• Problem with laptop Pavilion dv6 wireless connection

  I have a problem with a computer laptop dv6-6b50ea Pavilion of customers. He has win7 64 bit installed and an Intel Centrino WirelessN1030 with blutooth wireless card.

  The user has used the laptop abroad with a 3G usb dongle with T-Mobile, but now wants to connect to his home wireless router.

  Initially only the two switched 3g options are visible in the network for the connection options. Therefore, I uninstalled all T-Mobile software for control of the key usb 3g and removed the dial two profiles, but the laptop wouldn't see any wireless connection.

  The orange light was on the f12 key and I couldn't get the wireless to work. Finally I found that even if it has been enabled in the HP connection manager, it has been disabled by Windows Mobility Center. I finally got the light turns white but still saw wireless networks while two other laptops could see the router in the same place.

  I took the computer laptop and tried it on my own wireless network, and although he saw them he said that they were very poor and wouldn't connect. I tried all the normal things like turning off the antivirus and windows firewall. I've updated the software of the driver from the HP website, but it still wouldn't connect.

  Finally, in desperation I disabled two virtual connections created by the driver. Finally he saw all my access points Wi - Fi including some a long way outside. I have is that it connects and thought that I had a crush, but restarting it would link is no longer. Since I brought the oldes driver I can find on the Intel site, updated twice by HP Support Assistant, who has updated the bios and installed the latest drivers intel, but it now not see any wireless network, or if it does sporadically and does not connect. Ethernet connection works fine.

  I've seen lots of messages on mobile phones of series dv6000 with Wi - Fi and an overheating issues etc. What is the same thing with the dv6 6b50ea?

  Any suggestion would be appreciated

  I had a very similar problem with Tablet Dell Latitude slate ST of my son.

  He has the card brand Dell Atheros wireless bluetooth/wireless combo. He had connection problems in W7, but I was finally able to make it work most of the time.

  I saw on the Dell forums, a lot of people complain about this card.

  I installed W8 on the Tablet and there is no pilot, so I resorted to an old driver w7 and I can't get the map to work most of the time.

  So, I ordered an Intel 6230 without wireless/bluetooth combo card for it and I'll see if it makes a difference.  Intel has W8 drivers for the card.

  I did the same thing you did... inserted a map of the network, D - Link DWA-125 USB into the USB port.  W8 recognized, installed the drivers and it connects without any problems at all.

  The difference between my situation and your is however that the 1030 Intel has no problems experienced with W7 link I know, that's why I suggested a factory reset to see if you can start from scratch and exclude a hardware malfunction.

  If the card still does not work, then of course we should be replaced by a card support listed in the service manual.  Unlike Dell, with all computers laptops HP, you can install one of the maps in the service manual and they must have the part number HP on them or they do not work.

  Kind regards

• Vista's intermittent wireless connectivity

  I recently bought a laptop Sony Vaio with Vista. I have Norton 360 installed. My modem is Netgear PK5000. The connectivity of the laptop to wireless technology is intermittent. When I check the status of the connection it shows 'excellent' and 'trendy', but the phone displays 'no internet '. Looks like a connectivity issue between vista and wireless, but I do not know how to troubleshoot/repair. Help, please.

  Hello

  Check with the Sony Support, their drivers and documentation online and ask questions in the Sony Forums on well-known
  questions. Check also with NetGear support (are you sure it's a Netgear modem? PK5000 sounds like a
  Actiontec?). Also check with the help of the internet service provider.

  Your router could be suspicious here, you have successfully updated its firmware as a possible solution? And I would like to
  Update your WiFi drivers on computers. How you are positioned in the router? Are there
  obstacles in the path?

  Actually try updating your driver and disabling the network logon.

  Control Panel - network - write down of the brand and the model of the Wifi - double click top - tab of the driver - write
  version - click the driver update (cannot do something that MS is far behind the pilots of certification). Then
  Right click on the Wifi device and UNINSTALL - Reboot - it will refresh the driver stack.

  Look at the sites of the manufacturer for drivers - and the manufacturer of the device manually.

  After watching the system manufacturer, you can check the manufacturer of the device an even newer version. (The

• Problem on a Mac C6380 wireless connectivity

  Last week, I bought Photosmart C6380 AiO and implemented with almost no problems at all. Then I started noticing the same question as others on this forum have experienced in this abandoned rnadomly conntection, which would be only seemed determined by power cycling the printer and the Mac. I have since tried to uninstall and re-install all software related and have even updated the Firmware to see if this solves the problem without having to turn everything off and then whenever I want to print.

  The problem I have now is that I can't connect wireless to the printer AT ALL. I perfectly connects to the router and the wireless network Test report shows that everything seems to work fine, but then my Mac does not see it at all. The only small problem is that it is the address IP begins with 169.264, who, in another post about Wi-Fi-Guy here, says "but if it starts with 169.254 or 0, then we have another problem to deal with."

  So, I wonder if anyone can help with what to do about it?

  For now I'll have to work with a USB cable hanging out on my desk, that wasn't really the plan behind getting a wireless printer.

  Thank you.

  Will be

  Hardware and software configuration:

  -MacBook Pro OS X 10.5.7

  -Linksys WAG54G2

  I knew that it would be something really simple and obvious that I would not do. Thanks much for that! I ran a few tests that have been resulting in the printer and mac lose each other before, but good.

  Thanks again!

• Intermittent wireless connection; limited connectivity message causing to reconnect me

  I keep losing wifi connection, I receive a "limited connectivity" and need to plug and re =.  I have a HP dv6t running windows 7.  The network card is an Intel WIFI LINK 5100 AGN.  I sent an error report to HP and got a call and the tech said I had something about 6,000 error codes, that it should be deleted.  Unfortunately, I was at work and never got a call back.  You are looking for ideas.  Thank you

  Hello:

  I would a driver issue when installing the last direct of Intel driver for your card.

• U940 PSU6VA satellite - wireless connectivity problems

  _ * My specifications: * _
  * Model: * Toshiba Ultrabook (Satellite PSU6VA - 00S 002 U940)
  * Operating system: * Windows 8.1 x 64 (upgrade of Windows 8 x 64)
  * Wireless adapter: * Intel Centrino Wireless - N 2200
  * Wireless adapter driver version: * 15.10.0.12 (which is the last for my device)

  I got this Ultrabook since February 2013, and throughout this period, I always had problems with wireless connectivity, even after a factory reset. My wireless icon varies between three States:
  * Internet access
  * Limited (in which case I can't connect to the internet or any other device on the network)
  * Not connected - connections are available (and if I try to connect to the network, it will fail)

  Sometimes my computer would instantly reach the State of "Internet access" at startup and remain in this State. Other times, it would be 'limited' for several minutes after the start of my computer before it finally connected, and even in this case, the connection will drop out every now and then. In the worst case, it would indefinitely remain "Limited" or "not connected", regardless of how many times I reset my adapter wireless or rebooted my computer.

  Until very recently, I always thought that these problems have occurred randomly. However, I noticed recently that I have always a connection perfect, whenever there is no other computers connected wirelessly to my router, and I always have problems more or less when there is at least another computer (or even a smart phone) connected wireless to the router. If there is another computer connected to the router via an Ethernet cable, this causes no problems. It's only wireless connections that interfere with my computer.

  It is only this computer that has these problems; the other computers in my house ever experience these issues, no matter how many computers is online. In addition, my computer is not only these problems with my home router; It has the same problems on the network wireless at my University.

  My question is, how do I fix? Is this a known bug or is my defective wireless adapter? I know that I can connect using an Ethernet cable if possible (I have never problems with Ethernet connections), but this is not always possible at the University.

  Did you remove the old driver Win 8 Intel of the system before you upgrade to version 8.1 to win?
  The old Wlan Intel driver could affect the performance of a Wi - Fi connection.

  The driver update page Win 8.1 says clearly that Intel Wlan driver must be uninstalled and the
  Inbox Windows 8.1 version must be used.

• Intermittent problems of wireless connection in Windows 7 Ultimate

  I recently bought Dell Studio XPS 1645 Windows 7 Ultimate edition. I am facing a frustrating problem with Wi - Fi. The connection is down and reconnect. I have the adapter Intel Wireless 5300 AGN and a router Dlink Wireless G I tried to update the latest drivers from Intel (Driver Version: 13.0.0.107), disabling IPv6 for all network interfaces, configuration of the wireless adapter to only use IPv4 and so on. I have 2 other systems with XP Professional on my home network. As soon as I start my Windows 7 laptop, the chaos begins. The router restarts every few seconds, other disconnected systems and so on. I have not found so far any solution on the internet that could solve this problem.

  Other observations that may help to understand my problem:

  1. once my wireless adapter disconnects, the ping my router fails. It tells me whenever my system is asking for a new IP address.

  2 Event Viewer displays multiple entries, which indicates that the DHCP could not get an address. The error looks like as follows:

  The lease of the IP address 192.168.0.100 to the network with the network 0x00216A934EE2 address card has been refused by the 192.168.0.1 DHCP server (the DHCP server sent a DHCPNACK message).
  

  It gets an IP address later, but I do not understand why my adapter tries several times to get a new address every few seconds.
  DHCPNACK is the negative acknowledgement which router returns Win 7 DHCP client. I believe is that the client requests an address that is not available. Why would be client DHCP running on Windows 7 this?

  3. I have a D-Link WBR-1310 wireless router G with the latest firmware. Web sites of the reports that it is compatible with 32 and 64-bit Windows 7.

  4. I see no problems with the wired connection.

  As I type this, which could take a few minutes, my wireless connection rolled 7-10 times. All ideas, experts?

  If you need more information, let me know.

  I was able to find the main cause of intermittent disconnections on wireless interface. According to the information I have collected on internet forums and my research, I did as a result of configuration changes that have stabilized the connection. These settings work when you have N wireless adapter and a B/G Router:

  The wireless adapter settings:
  
  The driver for the most recent driver update.
  Access the properties of your adapter wireless network and sharing Center.
  Click on "Configure" and select the "Advanced" tab Make sure the following is in place:

  1 channel 802.11n for bands of 2.4 and 5.2 width are set to 'Auto '.
  2 disable 802.11n Mode
  3. Ad Hoc channel 802. 11b / g should be 1 or even that you have configured on your router.
  4. Ad hoc QoS Mode, keep WMM disabled - disable the router too. My wireless connection is stable once I made this change.
  5 fat Channel intolerant - disabled
  6. mixed mode protection - RTS/CTS enabled
  7 roaming aggressiveness - the lowest
  8 flow Enhancement - active
  9 transmitting the power - low
  10 mode wireless - 802.11 g

  Uncheck the box "Allow the computer to turn off this device to save power" on the tab "power management."

  Other Configurations:

  1. disable IPv6 completely. Uncheck 'Internet Protocol IPv6' in the wireless connection properties window. Repeat this for every other network connection you have.
  2. make sure you have the latest firmware installed on your wireless router.
  3 CTS Mode should be disabled in the configuration of your router 'Advanced Wireless' auto and WMM function.
  4. use only the WEP or WPA Wireless Security. Other methods have problems with 802.11n adapters.
  5. do not disable broadcasting of the SSID of your router. You don't need when your network is secure.

  I hope this helps.

• Satellite L755-1HW: problem of Intermittent Wireless with Sky router LAN

  I recently bought a L755-1HW Satellite from a dealer is seller renovated, but a condition of work entirely, after factory reset.

  I have trouble picking up my sky router (home network). It will pick up my iPhone when used as mobile and is access point find also all other routers of sky in the region, although it will automatically connect to mine intermittently and sometimes, can't find any as a wireless network connection. The sky router can be picked up fine by my father's laptop computer and other phones in the House so I think that the problem lies in the laptop and not the router itself.

  I have recently downloaded a driver for a wireless connection with my printer Epson SX420W, who, at startup, says "cannot reconnect all wireless drivers" If the printer is off, but even when the printer is turned on, the sky router is missed.

  I searched on the web and already done the following:
  1) updated the Atheos wireless network driver to the latest version
  2) updated the BIOS OF THE system to the latest version
  (3) scanned the PC using PC Diagnostic tools and the network is coming as a pass.

  Does anyone have an idea what I can do to fix this issue?

  Thank you very much
  Christian

  > I'm having trouble picking up my sky router (home network).
  Does that mean exactly?
  I mean that if the wireless network adapter is enabled correctly your laptop should detect your WLAN network. Is your WIFI detected and listed as available WLAN network?

• Pavilion (model 15-n019wm): intermittent network connectivity problems

  I'm having a problem with this laptop (product number 15-n019wm) where often, but intermittent network connectivity will cut. I ran a troubleshooting of Microsoft (results below) who said it has solved the problem, but the problem always. I tried a Ping in the command line when this happened for www.yahoo.com and she is "ping: transmit failed." General failure. "These problems occur when I'm wired or wireless, and when I have a problem with network connectivity, all other devices on the network can access the internet fine, it is therefore a problem with this device specifically.

• g505s 8.1 updates &amp; wireless connection problem

  I just downloaded updates Microsoft last night and as soon as I restarted, my wireless connection was gone/missing/non-functional. I have read some other posts that made me think that the issue may be with the (Qualcomm Atheros AR956x) wireless network adapter driver, but the download or install the latest driver from Lenovo (wlan149w81) support site didn't do me good. I do not see again for a Wi - Fi connection in the center of network & sharing.

  Someone at - he never saw something like this before / know what might be causing the problem?

  Hi solid Cruver - thanks for the help. Looks like that the combo of what I did and what you recommended has done. Update the driver LAN first and second WLAN driver seems to have solved the problem. Thanks again.

• Window7 & RaLink 802.11n & problem of the Netgear WPN824v2 router wireless connection

  Kevin Hau recommends a new thread to solve individual problems.  It's here.  In February 2010, I bought a new LG X 130 notebook with Windows 7 starter pre-installed.  On the first day, connection Wi - Fi was intermittent, although wired connection works well.  Links for laptop to a Netgear WPN824 V2 router.  This router has a wired to my PC and wireless for Toshiba laptop of my wife.  These work perfectly.  The latter two works on Win 7 Home Premium.

  I put WEP as a security measure for the router and wireless connections.  The LG X 130 connect wirelessly from a cold start about 25% of the time.  When it is not connected, no problems.  It should be necessary to restart, otherwise the computer expires then all that I get is "no connection is available" and there is absolutely no way to reconnect.  Cold boot does not work and the computer seems to need to set off for several days before it will condescend to connect again.

  Internet gives hundreds of 'my solutions' research which none appear not to work.  All the drivers are up to date and the latest versions.  I tried without security, WPA, WPA2, as some people suggest that 802.11n does not support WEP.  I tried b & g 108Mbps mode rather than by car.  All of these more recent attempts have failed to get any connection. On a recent trip away, the laptop could find the hotel network, but not connect to it.  He made a useful paper weight!

  The problem is clearly intermittent.  The laptop was returned twice to LG.  For the first time, they reinstalled everything, got a connection and returned.  The second time, they got a call and returned.  I can get connections, but I can't keep or make it reliable.

  Grateful for a solution.

  everything indicates material ralink or driver at this point... here, I had a
  best answer.
