• a6755y: a6755y wired and wireless network hard

  I already spoke with my ISP nothing helps technical support.

  I recently created my desktop computer again after having been stored for several months. Before I put it there, I was using wireless internet and local wireline connections regularly and without problem, and now I can not access to either. I have a strong connection with the modem/router device, so I thought that the issue could be in how its configuration or interpret the connection from my computer, but nothing, I have discovered has indicated that this was the case, and convenience store customer support my ISP did not find anything abnormal. I was now more confused when I discovered that it also fails to connect to another computer using a direct wired connection, even though I had in the past linked their and transfer large files regularly. I would like to assume that these issues are linked, to make the simplest solution; but as one involves a separate network adapter, and the other connects directly to the motherboard, I don't think that's likely.

  For any help or suggestion would be appreciated.

  Is this the same router that you were using before you put the computer in stock?

  How is the computer to the router? (Sometimes too much signal is as bad as not enough)

  What type of cable you are using for the connection from computer to computer, you mentioned?

  There is special software required?

  Have you other wireless devices that are connected to this router without problem?

• Disabled wireless network adapter

  The wireless network adapter in my desktop Pavilion (WE167AA under Windows 7 Home Premium) maintains have turned off. This can be fixed about half of the time by running the troubleshooter from network problems, but the rest of the time, the PC freezes during troubleshooting.
  
  The problem occurred only in the last two weeks, after nearly four years of perfect operation. I have no manual changes to configurations. Unfortunately I do not have a system restore point from before the show began. Performance on other wireless devices in the same room are very good, so I don't know that this is not a problem with the wireless itself.

• Satellite L750D-159: different problems: wireless network adapter, freezes, power

  Hi all

  2.5 years ago I bought L-750d-159:
  Video: AMD Radeon HD 6520G (TM)
  Wireless: Atheros AR9002WB-1NG wireless network adapter
  CPU: AMD A6 - 3400 M APU with graphics Radeon (TM) HD
  RAM: 4 GB
  OS: Windows 7 Home Edition SP1, 64-bit.
  BIOS: 2.1

  For the majority of the last 2.5 years I had the same questions, alternating between them over and over again without solution in sight.

  Repetition of questions: *.
  1. wireless adapter goes dead, no help of the troubleshooter in windows. Only restart help to, rarely he demans restart another. at the same time #2 arrives:

  2. cannot read USB (IE external HARD disk). allows you to restart.

  3. wireless mouse does not respond. Randomly, reset help.

  4 gel. Sometimes, when there is nothing running in the background. Of course, hard restart (only power button)

  5. office freeze.not always, but if he gets in the mood, he could go the days where minutes after I start the 'word' it would just freeze. Hard reset again.

  6. "atikmpag' blue screen. After not having it for a long time, I started just have it again.

  7 power supply and battery issues:

  7.1 with battery:
  Suddenly load stops. disconnect and reconnect do not help.
  Fresh only when the computer is turned off.

  7.2 without battery:
  Instant stop. Usually when you use Chrome.

  These issues are alternating, everyday sense I get something else, without a prescription for them that I noticed.

  * How to try to remedy: *.
  1. updated all the drivers for the toshiba page.
  [Page drivers Toshiba | http://www.toshiba.co.il/innovation/download_drivers_bios.jsp]

  2. update the BIOS. I do this cotton after having feeding problems, not so useful.

  3. formatting and reinsalled Windows 7 to factory settings.

  I am sure that there is a solution out there, the computer itself works fine for me (when it works) and I will not buy a new one, until it falls dead (I could give a year or two).

  Are you guys famliar with these questions?

  Here are the proven solutions for this model?

  > 1. Wireless adapter goes dead, no help of the troubleshooter in windows. Only restart help to, rarely he demans restart another.

  WLan problems could appear for different reasons. I don t think that it is a WLan driver problem. I think that you should just check the WiFi configuration.
  For example, you should check whether changing the WiFi 1-11 channel would improve performance. Also change the settings for encryption (WPA/WP2-AES, TKIP) is worth trying.
  Turn off all the settings for the WLan to save energy and check if there is a difference if you turn off the WLan mouse.

  > 2. Cannot read USB (IE external HARD disk). allows you to restart.
  Also the issue of USB can be related to energy saving settings.
  In the Device Manager-> USB Controllers-> properties-> tab power management option that allows the system to power off the device to save power.

  > blue screen "atikmpag. After not having it for a long time, I started just have it again.
  This file/process is tied to the ATI graphics card. Try to use the latest graphics card driver. An update is recommended in this case.

  Battery issues:
  Well, sooner or later each battery must be replaced. I put t know if your battery is malfunctioning but probably new battery would help to resolve the issue
  In addition, to remove and uninstall the device control method battery Microsoft acpi located in Device Manager.

  Hi @Mina85 and welcome to the Forums of HP!

  I see that you are having connectivity problems.  I would try to help!

  I recommend you to perform a power reset.   Unplug the power cord from the printer and the power outlet, then wait 60 seconds. After 60 seconds, plug back in the printer. Make sure that you connect the printer directly to a wall outlet. Make sure to bypass any surge protector or power bar.

  I also suggest this document on Center of troubleshooting wireless printing.

  Good luck and please let me know the results of your troubleshooting operations. Thanks for posting on the HP Forums!

• Best wireless network installation with the switch TP-Link

  Hi all

  Few question numpty maybe, but what follows... We just moved to a new (larger) home with thick walls and I want to set up a new wireless network.

  The current installation is:

  Fiber cable entering the House in the basement and connected the modem to the service provider that provides 150 mb internet. I changed the capacity wireless on the ISP's modem and connecting an airport extreme (2014 model) via the LAN to the modem. The extreme is in the office but on the 3rd floor is having connection problems than you can imagine. All rooms have access points CAT5e who all meet in the basement. I have two spare Aiport express and two Apple TV that I would use. Also I bought a TP-LINK 1000mbps (16 channels) Network Switch.

  Could someone please tell how the best set-up of my home network. For example, the Airport Express to the 3rd floor connected to the switch (wired) network or to an extreme in the Office? Apple TV also connected to the network switch?

  I would like to end up with a solid wireless network that passes without problem from extreme to Express necessary each time you walk and you want to use an Apple TV for television on the ground floor and one in our room.

  Many thanks and apologies once more for this very basic question... I have expanded my front (extreme Express) wireless network but just don't know how best to use the switch.

  Thank you

  The simplest up set... which is almost always the best game in place... would be to connect the switch 16 ports to the modem/router and then connect devices to the switch. In other words, if your modem/router has 16 + Ethernet ports, the simplest network configuration would be to plug as many devices as possible directly to the modem/router.

  Other variants are possible, for example, the network might look like this:

  Internet > Modem/Router > AirPort Extreme > switch > devices... or, you can connect certain devices to ports Ethernet on the AirPort Extreme and some to the ports on the switch.  One thing to keep in mind however... If there is a problem... Troubleshooting may not be easy since it will be difficult to know where the problem actually lies.  Much easier to all have, or of possible devices, connect to the switch.

  Unfortunately, the AirPort Express devices will be of real bottlenecks on your network.  These devices are notoriously slow as well as wireless, and even if they work well, the speed will be does not exceed 100 Mbps... since it's the speed of the port to the AirPort Express.  In fact, I expect each Express to provide a wireless signal in the range of 50-60 Mbps.

  Another thing to keep in mind of the wireless network is that Macs will usually a good work of tilting automatically to the point of wireless to the other as moving from one place to the other in the House... but the iPhones, iPads, PCs, and other mobile devices will do that very well... If they do at all.

  So with these devices, you will need to get used to temporarily disable the WiFi on the device and the device when you move in one region to the other, and then turn WiFi on must generally then pick up the signal from a nearby wireless access point.

• OfficeJet Pro 8625: HP8625 sleep mode/wireless network connectivity

  I recently bought an OfficeJet Pro 8625 and it worked fine for a few days, with everyone in the House, being able to print wireless connection network (Verizon FIOS via an Airport base station).  However, now it won't keep (or restore) a Wi - Fi connection after going to sleep.

  I can get the printer to work, if I turn it works, then immediately print (but only one machine... If I need to print from two different computers, I have to restart again to use the second computer).

  This is the case for all computers in my house - using several OS X (El Capitan, Mavericks and Snow Leopard) and the other with Windows 10.  I tried the troubleshooting tips that I could locate, and the firmware is up to date.

  I should be able to send a document to the printer from anywhere in the House, from any computer, without walking to the printer and restart it first.  A network printer should be sprained able himself, reconnect to the wifi and print jobs sent to it, but mine doesn't.

  How can I solve this problem?

  These settings are to set up your wireless printer to stay connected to your router, wireless devices stay better connected and makes your router secure and hack proof.

  While the DHCP is convenient, devices like printers must always be assigned an IP (fixed) manually to avoid conflicts on your wireless network.

  1. Set a static in the printer IP address (click here) outside the range of the DHCP of the router (check your manual). It is for Linksys routers, but can be used for all routers. Check your DHCP range and change this first if necessary. More Help Wireless Printing is here (Windows solution 4, static IP).
  2. Or check in the printer "Auto off" is disabled the System Mode Time Out is set to zero (0) Use the built-in webserver (EWS) by visiting the printer address IP address in the address bar of your browser, click on settings tab/Auto Off. Or use the printer, printer Home Page (EWS) Wizard. Also check the properties of your printers.
  3. If the printer supports and has IPv6 enabled, disable the IPv6 option in the printer.
  4. If necessary and you have assigned a static IP address, try using auxiliary for the preferred DNS Server 8.8.8.8 and 8.8.4.4 as DNS server.
  5. Wireless printers work only on the 2.4 Ghz band.
  6. Make sure the printer is on the latest firmware by checking with the HP support site.
  7. Check all devices wireless in your home for interference. Check microwave, babyphones, phones, wireless and wireless alarm systems are a big culprit. Any of these will knock at your printer wireless intermittently.
  8. Make sure that your printer and router are at least 6 feet, independently of the other.

  In the router: (refer to the manual of your router for more information)

  1. Use a fixed wireless channel as the 1, 6 or 11, never 'auto', try channel 1 first then the rest.
  2. Set the router to 20 Mhz only or 145Mbps router function.
  3. Always use WPA2-AES encryption (personal), but you can try the "mixed" mode
  4. Disable the WPS and never use it and disable the UPnP for the security of routers. No one can hijack your system now and help with wireless connectivity (if you want to know why, research on the web).
  5. If you have a router dual band (2.4 Ghz and 5.0 Ghz bands), make sure the SSID is NOT identical, they must be different for all the bands, even for networks without comments.
  6. SSID broadcast should be enabled.
  7. Save all the settings. Food at the same time, wait 2 minutes.  Power on router wait 2 minutes.
  8. Marketing the printer and check that it reconnects to the router.

  Windows 7/8/8.1 is discovered the system on or off?

  1. Control Panel/Network and Internet/network and sharing Center / advanced sharing settings.
  2. Under home or work (current profile) / network discovery.
  3. Select "Turn on network discovery" and save the changes.

  Now last thing to do once everything above has been tried and you still have the same problem, completely uninstall and delete the printer and its software.

  Use http://www.iobit.com/en/advanceduninstaller.php and powerful Scan at the end.

  Now go back and reinstall the drivers and full software on the HP website.

  Last resort effort - if your printer has an Ethernet connection, suggest you to get some adapters line and convert your Ethernet wiring for your printer.

• Equium A60 - 157 HELP Card/PCMCIA wireless network!

  Hi all!

  This problem has been frustrating me for at least 2 months.

  OK, I recently bought a Belkin Wireless G Notebook Card (wifi card).
  The first time I installed the wifi card it worked perfectly. I powered
  extinguish your laptop (after I had finished working on it). The next day
  When I turned the laptop on, you guessed it, the wifi card was not
  work. I did not remove the wifi card for the power off/power on stage.

  When I went into Device Manager, a yellow exclamation point was
  above the wifi card. When I looked at the properties of wifi cards, I found the
  following message appears:

  This device cannot find enough free resources that it can use. (Code 12)
  If you want to use this device, you will need to disable one of the other devices on this system.
  Click Troubleshoot to start the troubleshooter for this device.

  I tried unistalling and reinstalling the wifi card. I tried to use the latest Belkin drivers for the wifi card. Sometimes it works, but when I have the power turned off/turned on the laptop it s not go.

  One of the ways I got the card to operate was removing and inserting the card several times
  until he finds resources and finally worked. I put t use this method as, obviously, I might damage the cardbus slot and the card. In the meantime I ve been using a Belkin Wireless G USB network adapter. I had no problems with the USB adapter, but I prefer to use the wifi card. This is because the majority of the wifi card is housed inside the laptop, so it s not easily evicted. The USB adapter is great for wireless networks inside, but too risky for roaming outside.

  I had this problem of 1.70 at 1.8 ° C bios version, and I still have it with revision 1.90. I intend to return m wifi card in the store for an Exchange, but I have a really bad feeling that the same thing will happen with the replacement of the card. I m not convinced that the current wifi card is defective, because it works perfectly when he gets the resources.

  I tried to manually configure resources on the devices, but I have a major problem. Windows seems to be LOCKED in the automatic settings. The automatic settings check box is grayed out completely, it is impossible for me clear the checkbox. I did not take anything in the bios that can help me solve this problem.

  I noticed that there are many devices running off IRQ (interrupt requests) 19, when you view resources by type in Device Manager. These devices are:

  Standard enhanced PCI to USB Host Controller
  USB host controller standard OpenHCD x 2 (two entries)
  Texas Instruments OHCI Compliant IEEE 1394 Host Controller
  Controller CardBus Texas Instrumetns PCI-1410

  When the wireless card works she also runs IRQ 19, but as I said before Windows is locked in the automatic settings and do not manually configure the hardware resources.

  Equium A60-157 is not provided on board, but it has the potential for. WiFi L.e.d. on the front panel, physical location for wifi turn on side panel wireless icon and F8. Someone know if Toshiba offer an upgrade service, or can I install wifi on board myself?

  ANYONE, PLEASE HELP ME WITH THESE QUESTIONS!
  Thanks for your time!

  Hello

  I found this for you:

  Both devices have received a same ports of entry/exit (e/s), the same interrupt, or the same Direct memory access channel (whether through BIOS, the operating system, or a combination of both). This error message may also appear if the BIOS did not allocate enough resources to the device (for example, if a (USB) universal serial bus controller does not get a break in the BIOS because of a damaged MPS (Multiprocessor) system table).
  You can use Device Manager to determine where the conflict is and turn off the device in conflict. On the tab General properties of the device, click Troubleshoot to start the Troubleshooting Wizard.
  Try disabling the features of conflict. It will be interesting to know if the problem will occur again.

  In my opinion, you should contact the Service partner and ask them if the unit is ready for the Wi - Fi module. Sorry, but I'm not sure about that and I don't want to give you a bad information about it.

• Satellite L500D wireless network card issues

  Over the last week I had problems with my Realtek wireless adapter... The wireless or the other works for about 30 minutes, a troubleshooting questions or laptop
  cannot locate the adapter wireless at all.

  Whenever I restart the laptop, he returns with one of the following error messages on the network wireless driver

  (1) Windows cannot verify the digital signature for the drivers required for this device. A recent hardware or software change might be installed a file that is signed incorrectly or damaged, or maybe it's a malicious software from an unknown source. (Code 52)

  (2) this device cannot start. (Code 10)

  or other times wireless driver cannot be found at all.

  I tried to uninstall the driver wireless and re - install... updated the BIOS and even a full recovery of the system however nothing seems to work.

  Any ideas?

  Hmmm, I think it might be from hardware, which means that wireless network adapter needs to be replaced, but before that you would get in touch with a local ASP, please set the BIOS to default settings and install the WLan driver from this page:

• Re: Satellite L450-173 - unable to detect wireless networks

  I have a similar problem with my satellite L450-173.

  I bought this laptop without OS and installed win 7.
  I found and downloaded the latest drivers toshiba WLAN support and download page and my Device Manager indicates that the device is turned on and that it works correctly.

  However, I am unable to detect the networks without wire in the box (alltough there are at least three in the district).
  I have a home network with the router. When I connect to my laptop with a LAN cable, it connects automatically without problem. But I can not connect via my wireless connection.

  Windows troubleshooting is of no use.
  I downloaded the chipset drivers updated too (following the suggestion by an online forum), but which did not help at all.
  My "doctor Conectivity" reported that my wlan adapter is 'on', but when I enter the 'Radar' option, it reports that this wireless network device is disabled. I tried to disable and then enable once again, but it did not help. I also used the option reset address IP - no use. My IP address is set to auto because my network is connected by the router.
  I tried pressing FN + F8 but I have not noticed any change.

  Indicator LED for a wireless connection at the front of the laptop is always red.
  I read many forums linking similar issues to win 7, but I have not found any solution.

  Any ideas?

  Hello

  Eventually the WiFi network is disabled and so you cannot connect to the Wlan router.
  If the FN + F8 does not change the status of WLan, then it would mean that Don t FN buttons work properly have you checked if the other FN keys work?

  You must reinstall the VAP (value added package) to obtain the keys FN working again
  If you want to use the Fn + F8 then you should see (flashcard) WLan icon on the screen

  Another idea;
  You can toggle the wifi in the Device Manager-> card Wlan-> properties-> Advanced tab.
  Check this box

  PS: If the BIOS is not updated, then you need to update it too!

• Cannot connect Tecra 9000 to wireless network

  Hello

  I am trying to connect my laptop Toshiba T9000 to my BT home Hub 2.0 Wireless v but a little difficulty.
  The laptop recognizes the hub, but every time I click on connect, I get the same message.

  ""Windows cannot connect to the selected network. " The network can be is no longer in range. Please refresh the list of available networks and try to connect again"

  I went through a few troubleshooting steps to resolve this problem, but always without success.
  Can I update the driver? My inclination is that this may have something to do with the laptop is not able to support WPA?

  I am not very computer but if anyone has any additional input to help me with this question then I would be very happy.

  Kind regards
  Answer by quoting

  > Can I update the driver? My inclination is that this may have something to do with the laptop is not able to support WPA?
  This may be possible

  The point is that this laptop is an oldie and the wireless network adapter appears to be old too.
  I ve no idea what WLan card you have, but you could try to connect to the WLan without use of encryption settings. Disable encryption on the router Wlan and test connectivity again. of course, this must be done only for testing purposes
  The wireless network must be always secure

  The alternative could be the use of external USB WLAN, it would be the easiest and fastest way for that to be resolved
