• Satellite A100-784 - Intel PRO Wireless 3945ABG off randomly

  Hello

  I have Toshiba Satellite A100-784 with Intel PRO Wireless 3945ABG wireless adapter.
  Today I was working with my friend on some project connected on his wifi sharing internet connection on Toshiba Satellite A100-510.
  After a while I lose the internet connection and I see that this blue icon is no longer in the test system.

  I try to use Toshiba ConfigFree but it was impossible to open, so I try to open the network connection of the control panel and after a period of time the network connection has been accessible and I saw that this network adapter is disabled. I try to activate three times but nothing.

  After rebooting, everything was ok and wireless adapter is turned on and ready to use for the next 10 or 15 minutes.
  First disable comes after two hours. I use Windows XP SP 2.

  The problem is that I have to restart my computer everytime where I lose internet connection (WiFi is turned off automatically).
  Everything is blocked its very hard to access the settings of network or toshiba configfree

  Thank you

  Try this:

  Update the BIOS of the laptop
  Update driver Intel Wireless LAN
  Use static IP addresses, instead of dynamic (DHCP)
  Temporarily disable your firewall software
  Update the Firmware on your Access Point

  Go to: Control Panel, Manager of Devic, adapters to extend your network, click with the right button on your wireless network and click on uninstall.

  Do not put a check in the box: remove the software driver for this device.

  Restart your computer and Windows will install your wireless network.

  If the problem persists, see if your computer manufacturer has an updated driver.

• Intel PRO/Wireless 3945ABG Network Connection problem under Win XP (Latitude D430 computer laptop)

  I use Latitude D430 Laptop & Windows XP. Initially, it is ok, but after some time I have a connection problem. I have run the diagnostics & "Radio Test" failed. Any idea about this problem? The problem is solved only when I restart my computer. I think the Win XP driver problem because I don't have this problem when I use Win Vista. Everyone knows it needs to solve this problem?

• Portable win 8 frequently loses connection wifi

  Buy brand new laptop with Win8 Pro installed.
  MSI GT - 70 / i7XM/32 GB of RAM
  Intel wifi card

  Laptop has had problems with the wifi since the beginning.  Sometimes spend a whole day, sometimes lost wifi after about 20 minutes.  Workarounds for many working restore wifi:
  -airplane mode on / off
  -Restart WlanSvc
  -Restart the computer

  Instead, I use this laptop for business, I am obliged now to use with Ethernet only when dealing with customers.  Excruciatingly painful.

  There is nothing wrong with my wifi at home - several other laptops, tablets and phones all hums along without interruption.  It is only $2000 + brand new laptop that breaks down frequently.

  All drivers verified to date: no change.
  All checked the firmware up to date on router: no change.
  Wiped computer in its entirety and rebuilt: no change.
  Card replaced wifi adapter: no change.

  Simply, this is not satisfactory.  Please help.  I have work to do and I'd like to be able to do with my work instead of a power machine laptop low vintage 2006.

  It's fixed!

  None of the technical solutions provided on this website provided a fix, but here's what finally makes a difference.

  Win 8A power of material management control.  It seems that this feature of power management is defective (for a very large number of people) and turn off the wifi adapter once from time to time.

  To solve this - go to network and sharing Center

  Click the Wi - Fi network in use

  Click on the properties button

  Click on configure

  Go to the power management tab

  Clear the check box.

  Fixed!

• Intel PRO/Wireless 3945ABG slow wireless

  Hello
  I reformatted my laptop on a wek ago, and since then, I've noticed that my wireless works more slowly than usual.

  Before he was reformatted my download speed is about 240KB, but now it's about 160KB download. It is not the source of the download as my old Toshiba with an external wifi adapter gets about 240KB download the same file.

  I've updated the drivers to those most recent outside, but it has not changed a thing.

  I don't know what I can do and any help will be appreciated.

  Dan

  Hello

  Your Intel Wireless card supports three different modes of WLan: A, B and G
  These three different modes that also supports different speeds.
  In my opinion your use a slow or well the server mode where you download files of does not support a faster speed.

  All WLan settings, you should find in the WLan card properties. He just go to Device Manager, select WLan CAD and click Properties.
  On the Advanced tab, you'll find plenty of options, and there you can choose A, B or G mode.
  Additional I recommend you disable the saving on this card.

• Intel Pro/Wireless 3945ABG cannot load the driver

  Wireless worked fine since I bought this laptop

  Now it has stopped working and has a yellow exclamation mark in Device Manager - it says "this device does not work properly because Windows cannot load the drivers required for this device. (Code 31) »

  So I uninstalled the device and check the box that says "Remove the driver for this device", then reinstalled the latest version of the driver on the Toshiba site 11.5.0.32.

  Windows Vista detects new hardware and install the driver, but fails with 'Windows found driver software for your device but encountered an error trying to install it. The system cannot find the file specified. "

  All ideas

  Remove the wireless network adapter in the device, download manager driver the latest from Intel page and repeat the procedure of installation of the driver.

  Good luck

• Satellite A200 - Intel Pro Wireless 3945 fall

  Hello
  I have a problem with my laptop Satellite A200 (with Vista Home Premium 32 bit) where the Intel Pro Wireless connection keeps itself turning off after several minutes or several hours of use.

  In network connections, the wireless connection is shown as people with reduced mobility. When I try to enable it, it will say something like "Enable already ongoing attempt". And he's never coming back. However, wireless orange light is always on the cell phone all the time. The only way to reactivate the wireless connection, is to restart the system.

  I know this is a very common problem, I see the same problem among other threads on this forum.

  After a short search on Google, and I see that many other people have the same problem too, particularly with Dell laptops. Forum sites there 2 in particular, that have the most information on this topic, I found:

  http://www.vistaforums.com/Forum/Topic4198-45-1.aspx
  http://thevistaforums.com/index.php?showtopic=9834

  These are the things that I tried to resolve this problem:
  (I got all the drivers from the site http://www.toshiba.co.nz, that I got this laptop from NZ and the specific laptop model number is PSAFCA A200)

  -Updated the BIOS with the latest version.
  In fact, I think that updated the BIOS could be the cause of this problem wireless, or in part. Because a few months back, the laptop kept cutting itself no reason apparent, perhaps once or twice a week. So I've updated the BIOS, which actually fixed the random stops, but since then, I've known this wireless problem. Coincidence maybe.

  -Upgrade to the latest driver for the wireless network.
  I tried a various number of drivers. Later off the coast of http://www.toshiba.co.nz, http://aps2.toshiba-tro.de/wlan/, http://www.intel.com. None of them have worked.
  For the moment, I use the older driver comes preinstalled with Vista.
  Intel Pro wireless 3945ABG (Microsoft) was sometimes since 2006. And surprisingly, this one works best. Drop-outs are not as frequent as more recent drivers, but the problem still happens.
  With this new drivers (dated from 2007), I find that it turns off several times a day. Once or twice an hour.
  With the former, once every two hours.
  That's what I feel, it is probably coincidence.

  -Update of Windows Vista with service pack 1.

  -Updated the firmware on my router. It is a DLink G604T. However, I doubt that it is one router problem, my other laptop running fine without any abandonment wireless.

  -Power WLAN disabled economic option.
  Under power settings, select the setting of maximum performance.

  -Set lowest roaming aggressiveness, even tried with highest.

  -On the "Power Management" tab in the properties for Intel Pro Wireless 3945ABG Network connection, tried to activate and deactivate the option "allow the computer to turn off this device to save power".

  -Done a full virus/spyware scan.

  -Uninstalled the software Toshiba Wireless Zero Configuration.

  I think I've tried just about everything that I can, so I'm here pretty much as a last resort.
  I hope someone can help me solve this problem.
  It was so annoying since many months now! It's not fun to have to restart the laptop all the time.

  Thank you.

  I see that you have tired most of the things that I would say too
  You said that WLan works better using the old driver Wlan MS if it s really a WLan driver problem

  But what said
  I searched a bit in the MS knowledge base and found this article:
  + Several problems occur on a Windows Vista-based computer when you work in a wireless network environment.
  http://support.Microsoft.com/default.aspx?scid=KB; EN-US; 932063

  Check it out.

  But a friend of mine had a similar problem of Wlan and nothing helped, he did a update BIOS, set the Wlan driver, etc.. nothing!

  Finlay, he changed WiFi channels.
  He chose the other channel on the router and wireless network and since then the Wlan card works well...

  Maybe it s worth a try!

• SP1 RC rest + mobile pro/wireless 3945 problems

  Yesterday, I reinstalled VISTA and apply the SP1 RC Refresh on my SS SX17a which uses the Mobile Intel (r) 945 GM Express Chipset.

  The reinstallation of VISTA Business edition (6.0.6000) caught around 50, it took almost 3 hours to bring in SP1 RC Refresh via autoupdate on a 10mega ADSL link... I started with 41.6 GB of free space and endedup with 39. Lets hope the final SP1 has a possibility not to save the changes for those who ask the SP1 for a new installation.

  No error was reported, but the machine crashes whenever I have turn off the wireless LAN using either the Toshiba soft-switch or the material on the laptop. The laptop has Intel PRO/Wireless 3945ABG chip and came up with the Intel v.10.6.0.29 driver installed. I tried to install the latest driver from v.11.5.0.32 of Intel and demotion to the v.11.1.1.20 of the MS driver as of 21/06/2006, but the problem persists. v.10.6.0.29 works since April without problem.

  WLAN is not configured and therefore no IP address is passed through the router and the PC can't see the WAN, but VISTA the adapter needs to be on, if not, that it is qu' il se bloque blocks... fall time varies, sometimes it fails when connecting, others a few minutes after (a few times, it crashed when I accessed a SD card via a built-in player.

  The crash isn't a total freeze, blue screen, no messages, nothing... Finally the laptop fan made in power until a max and I have to power down. The facility is clean, nothing else was installed as SP1 RC...

  When I disable the driver in Device Manager, the machine freezes almost immediately, but when I restart the I need WIFI works without problem and the machine not crushed (so far anyway...)

  Has anyone else noticed a problem with the 3945ABG chip? It's as if VISTA does not treat it as a plug n play... or the current drivers work well with the new SP1 USB drivers to level v. 6.0.6001.17128?

  And Yes, this is the pre-release software, but it is very close to release...

  To be clear on your questions: SP1 is just the beta version and it is not in official use. When the SP1 will be in official use that Toshiba will use it on recovery image. All problems must be fixed, probably using new and suitable drivers.

  At present, it is not easy talking about this because there is no official solution.

• My pro iPad connects to the WIFI, but loses connectivity to drops in use.  My other IOS devices (iPhone, macbook, etc.) do not have this problem.  Ideas to solve?

  My pro iPad connects to the WIFI, but loses connectivity to drops in use.  My other IOS devices (iPhone, macbook, etc.) do not have this problem.  Ideas to solve?

  Hello BrooklynWM!

  I definitely want my iPad to stay connected to the Wi - Fi connection while I use it.  Thanks for posting that other iOS and OS X devices have no problem with the connectivity dropping.  We can try a few things.

  Would first go through the steps listed in this article: If your iPhone, iPad or iPod touch connects to a Wi-Fi - Apple Support Network

  Then if it does not help, you can check network settings with this: recommended for the WiFi routers and access - points Apple supported

  After trying those, if you still see the drop connectivity, make sure the iPad Pro is updated with iOS 9.3.2 and check to see if the connection when you are in a certain place, time, or one event happening elsewhere in the House.

  Best regards.

• WiFi loses connection intermittently and the erasure of the arp arranges

  This has been asked before many times, but none of the above worked for me so far.

  I have a MacBook Pro with El Capitan on it. From time to time, usually 5 to 10 minutes,

  my connection drops and I can browse the internet. As:

  4 bytes of 8.8.8.8: icmp_seq = 7646 ttl = 53 time = 13,091 ms

  64 bytes of 8.8.8.8: icmp_seq = 7647 ttl = 53 time = 17,035 ms

  64 bytes of 8.8.8.8: icmp_seq = 7648 ttl = 53 time = ms 13,716

  Request timeout for icmp_seq 7649

  Request timeout for icmp_seq 7650

  Request timeout for icmp_seq 7651

  Request timeout for icmp_seq 7652

  Request timeout for icmp_seq 7653

  Request timeout for icmp_seq 7654

  Shooting, then turn on the WiFi will fix the problem, but I tried to limit the problem

  and I discovered that deleting IP of the route in the arp table will also fix connectivity

  immediately:

  $ sudo arp d 192.168.0.1

  Request timeout for icmp_seq 7718

  Request timeout for icmp_seq 7719

  Request timeout for icmp_seq 7720

  64 bytes of 8.8.8.8: icmp_seq = 7721 ttl = 53 time = 10,947 ms

  64 bytes of 8.8.8.8: icmp_seq = 7722 ttl = time 53 = 11,966 ms

  64 bytes of 8.8.8.8: icmp_seq = 7723 ttl = 53 time = 12,576 ms

  64 bytes of 8.8.8.8: icmp_seq = 7724 ttl = time 53 = 11,058 ms

  64 bytes of 8.8.8.8: icmp_seq = 7725 ttl = 53 time = 15,173 ms

  Deactivation of unicast arp has NO had no effect either:

  $ sudo sysctl-w net.link.ether.inet.arp_unicast_lim = 0

  Notes:

  -J' have two MacBook Pro at home. Other works without problem.

  -My phone and other devices work also with the same router with no problems.

  -The problematic MacBook works with other WiFi networks without any problem.

  What could be the problem?

  Yes, clear arp fix it. Very familiar with it.

  I had this problem for 2 years and more than 2 or 3 MacBooks, on El Capitan, Yosemite, and Mavericks.   I Googled it every 1-2 years months.  I captured packets and tested several access points... The best fix so far... is the arp compensation, and I have the automated at the moment:

  in a terminal:

  While true; make sudo arp - da; sleep 2; fact

  When the window is open, every 2 seconds, my arp table gets undervalued... and if I lose connectivity, the maximum cut is 1 to 2 seconds.

  I noticed that in some places, I don't have the problem... its as if my laptop reacts badly to some other customers on the same WIFI network.  This question makes me crazy, and I can't imagine how was such years.  If I don't fix it manually, I find myself for 30-120 seconds every few minutes.

• WLan signal is poor and often loses connection - Satellite Pro L10

  I have a Satellite Pro L10 and a home network, where I used two Belkin and Netgear Routers ADSL Wireless.
  My L10 always reports very low signal and often loses the signal unless I'm VERY close to the router.
  I have three laptops and a desktop at home and they all have very high or excellent signal.

  I changed my router and even installed a Netgear wireless card in the L10 (in case there is a problem with the Intel Pro/Wireless 2200BG, but he pointed out again and again a weak signal.

  Someone else had this problem?

• cant WiFi connection HP Officejet Pro 8600 e-all-in-one printer to internet

  I can't get WiFi HP Officejet Pro 8600 e-all-in-one printer connect to internet... at least I think that's the problem. I followed all the instructions on the HP print and Scan doctor as well as solve problems of failure to install HP. My router is working fine for everything else and I entered the router the static address for the printer.  It seems that my printer thinks it's connected to my WiFi (Ihave WPS it several times), but when I type there nothing appears in my IE IP address. My router does not see the printer either. I have the latest driver installed on my computer. I suspect that this may be a router problem: new Asus Double 450 Mbps N Router router (dual - band, but it appears my router uses the 2.4 Hz band to connect with WPS). Windows 7 64.

  Any help is appreciated!

  Hello NRHII,

  Welcome to the HP Forums!

  I understand that you are unable to connect the Officejet 8600 via a wireless connection. I will do my best to help you! I would recommend power cycling the router, the printer and the computer:

  (1) turn off your printer
  (2) unplug the power cord at the back of the router
  (3) restart your computer
  (4) wait less than 60 seconds, reconnect the power cord to the router
  (5) turn the printer, wait for the computer to turn on

  The wireless light blinking on your printer? If so, please reconnect the wireless on your printer using the Wireless Setup Wizard: (this information is declared here.)

  1. On the touch screen of the printer, press the right arrow key ( ) to display the second navigation screen.
  2. Tap the Installer icon ( ).
  3. Tap network , tap the wireless configuration wizard , and then press continue . The printer looking for available networks.
  4. Tap the name of your network and then press OK .
  5. If you are prompted, enter the password for the network, and then press OK . The printer connects to the network.

• OfficeJet Pro 8600 all-in-One connected as network printer loses connection

  In December 2011, I bought a HP Officejet Pro 8600 all-in-One to replace an Officejet 6500 as my network printer home. The 6500 worked very well on my cable, but his screen did not, I tried some of the features offered by the 8600 and I got a good price on a new warehouse of BJ. I have the 8600 connected via ethernet (not wireless), with a static IP address. All my computers on the network are running Windows XP Pro SP3 and are up-to-date with Microsoft updates. However, from one day to the next my 8600 will lose connectivity scan (Scan of the computer shows it as being disabled on all my computers at the same time, and I can't reconnect), and if I do not have anything he'll (as in a few hours) also lose connectivity impression. The only way to restore connectivity is to uninstall the HP Officejet Pro 8600 device software basis of all computers, and then reinstall the printer. I had a phone conversation and two debates with HP Technical Support; They suggested that the problem is in the firewall on the computers (but if that were the case I don't think that the loss of connectivity would occur on all computers at the same time), the IP address setting (doesn't make sense) and the printer driver is not not the latest version. I tried all the suggestions, and none of them have solved the problem. The last counselor "has raised the issue to the next level", which proved to be a Manager with no technical expertise and his only suggestion was that I have to return the printer to the merchant. I think the problem is the firmware in the printer (which, according to the 'update' on the printer option, is the latest version). Any other suggestions or experience?

  After a lot of research and find the settings that I did not know that Windows XP offered, I found that the following appear to have solved the problem I've known - at least the printer is now operational for more than 48 hours without losing printing or scan connection. Here are the steps I used:

  1. Start Control Panel  connections network and Internet

  2. Choose "network connections."

  3. Right click on "connect to the Local network.

  4. Choose "Properties".

  5. In the top window is the name of the Ethernet computer connection port, select "Configure" next to this window

  6. Select the tab labeled 'Power Management'

  7. Uncheck the box "allow the computer to turn off this device to save power".

  8. Select the "Advanced" tab

  9. Select the entry "power saving Mode".

  10. If this entry is set to change 'On' to 'Off '.

  11. Select 'OK', and then close the windows that were opened
