Wifi Card Not Working After Restart

Feb 26, 2013

After restarting my laptop my wireless card (Intel Centrino Wireless-N 1000) has suddenly stopped working (ThinkPad SL410 with Windows 7 Pro 64-bit). The hardware switch is on, the software / Fn switch is on, drivers are recent, device manager says the device is functioning properly, but there's a red X on the network icon in the system tray and obviously no wireless networks are showing up. I thought the wireless card died, but I booted off a linux live CD and the wireless card works just fine.

Hp Pavilion P6685l No Wifi Card But Working Fine

Apr 3, 2011

Had a look inside my HP Pavilion p6685l recently and found there wasn't any wifi card which was odd because it's been working fine for months.Device Manager says theres a 802.11n Wireless Lan Card in there but I traced the wires from the ariel to a chip on the board (MSI 2A9C according to Belarc ). Property sheet says it's a Ralink Card and so does the vendor id ( 1814 ) but the device id (3092) belongs to an Intel I20 1.5 Raid Controller which is where I got lost. I didn't know Raid Controllers did wifi.

Ethernet Port Quit Working After Restart?

Nov 22, 2011

I recently installed Arkham City on my computer played it for a while, tried google chrome, gave me a corrupt profile error or something (internet still worked and was connected at the time) restarted my computer and now it's telling me there isn't an ethernet cable connected to my computer.

Here's what I tried so far:

-Uninstalling and reinstalling the driver

-Updating the driver

-Using the network troubleshooting for windows 7

-Doing a system restore before I installed the game (gave me an error saying could not complete restore)

-Currently scanning my computer in safe mode with networking (seeing if that might work, doesn't) with malewarebytes

-Unplugged and replugged the router and modem

-Checked the router on another computer to see if there's a connection (there is none)

-Checked the router to see if there is a light in the port connected to the ethernet, it's blinking at a very slow a steady pace, unlike the ones around it which are solid green lights

-Tried the ethernet cable on another computer, works fine.

computer specs:

Windows 7 64-bit home premium edition
Gigabyte GA-MA790X-UD4P
NETGEAR router WNDR3700

Wifi Not Working On Asus Laptop - Lan Working Fine?

Feb 15, 2013

ASUS Notebook G60Vx Series

Windows 7 Home Premium 64-bit

Intel(R) WiFi Link 5100 AGN

A few days ago my internet suddenly stopped working. I plugged in the ethernet cord and everything worked fine. Checking the properties in the device manager showed the device was working properly, I also tried resetting it to make sure it was enabled but it did not work.

Upon troubleshooting, the "Windows Network Diagnostic" said the problems was that the Wireless adapter was not turned on. Using the switch on the front of the laptop as well as the function keys does nothing. Usually a graphic pops up showing if the WiFi is on or off, changinging transparent to show the WiFi is disabled. Now when I turn the switch on it always appears transparent, effectively going from off to off

So I know the computer reads both the function keys and the switch on the front but both methods never actually turns the adapter on. I just finished a system restore and nothing has changed

On-board NIC Card Stopped Working?

Mar 3, 2013

I have a toshiba satellite laptop (windows 7) with wireless on-board and an ethernet cable port. Up until last night, both worked flawlessly since I bought the computer a few years ago.

Now, the wireless still works in three different locations I have tried (i.e. three different networks), but the ethernet cable will not work. I thought it was the ethernet connection on the mobo at first, but then after acquiring a USB-NIC connection, I found I had the exact same problem... I can't connect to my router or even direct to the DSL modem using a ethernet cable. I know my system is good since all my other computers (7) work with wired connections, and my laptop doesn't work on other cables on which other computers do. Essentially, it appears that my computer has lost the ability to get an i.p. address using an ethernet cable of any kind. Both the onboard card and the usb-nic cable tell me they are 'working correctly' in the systems/devices/network adapters section. I have tried disabling one while trying the other. I have tried disabling the wireless while trying either, and still nothing.

Reinstall XP Wireless Card Not Working

Jul 2, 2011

I have a Dell Dimension desktop 4550. I did a reinstall of Windows XP sp2. Now I am having an issue with my wireless card. I am unable to install the driver. I don't have the original CD that came with the card. The wireless card is a Buffalo Air station wireless G. I went to the Buffalo site and downloaded the driver from the model number on the wireless card. I then attempted to install the driver using the Device Manager from a folder on my desktop. No such luck. I also tried to install the driver from the Device Manager using my memory stick. But that didn't work. I did uninstall the wireless card before attempting to install the driver. Now, My PC does recognize the wireless card and asks me to install the driver after every start-up.And yes the Device manager has the yellow exclamation point and exclamation marks under the Ethernet controller multimedia Audio controller and Network controller.

D-Link DCS-942L :: Not Working Over Wireless With SD Card

Dec 14, 2012

My DCS-942 is doing everything quite well, except when an SD card is inserted.  When connected to the network via ethernet, everything works well.  I can set detection zones with snapshot or video modes and it does what I want it to do, however, as soon as I remove the ethernet cable and wish to use the camera over wireless, the unit fails to work at all (red light illuminated).  If I then remove the SD card, it will work over wireless again with all the capability except for SD oriented operations.  I have performed several hard resets and formatted the card with no success.

Cabling / Cards :: Wireless Card Only Working On Second Boot Up

May 5, 2012

I built a computer a while ago, from a reasonably low budget. Ever since the very first boot up, the wireless card (TP-Link, unable to find model currently, will add later) only works on the second consecutive boot up. I have no idea why, I have not found anything relating to a problem like this, the computer doesn't even appear to know that there is a wireless card in it. Instead the icon shows a cable, suggesting that the computer isn't connecting with the card.

Dell Inspiron 7600 / Realtek Wireless Card Not Working?

Feb 7, 2011

I recently bought a new Dell Inspiron 7600 pc running on windows 7 home premium and to enable access to our wireless internet I installed a Realtek 8185 wireless pci adaptor. It has worked fine (although not without the occasional blip) but recently it has stopped working. I could connect to our wireless network but connection came with a small exclamation mark on the wireless connection icon in the system tray. I tried reinstalling the most up to date drivers I could find on the realtek download website and this has removed the problem of the exclamation mark with the wireless connection claiming it now has internet access. However the internet is now so slow (vastly slower than before these problems began) I get timed out errors whenever I try to access any web pages. I have ruled out the router being an issue as my two housemates' computers are working just fine.

Dell :: Wireless 1500 WLAN Card Utility Not Working?

May 31, 2011

I have a Inspiron 9400/E1705 laptop with the Dell Wireless 1500 802.11n WLan card when I try to use the utility I get an error message that the internal settings are bad and to restart the computer to fix. It does not fix this. I am currently using the windows wireless to control the card. Is there a way to fix this, It used to work fine just when I downloaded the R151519 update now even when I use a previous update I still get this error. The driver is Broadcom dated 10/12/2006 version 4.100.15.5

Dell :: D820 - 1390 WLAN Mini Card Not Working

Feb 2, 2012

I recently re-installed the driver for the 1390 WLAN Mini Card after not having wireless for a few years, and have a few problems.  In the Windows XP Home Network Connections folder, the  Wireless Network Connection Icon shows, "Acquiring Network Address", but never gets past that.  I ran a diagnostic in the "Dell Wireless WLAN Card Utility" and the card passed all the tests, even though with the card switch in the on position the LED doesn't light (??) 

When I right click on the Wireless Network Connection Icon and choose, "Status", in the "General" tab I can see that the card is sending out packets, but none are being received.  In the "Support" tab under "connection status"  the following appears:  "Address Type":  Invalid IP Address, "IP Address": 0.0.0.0, "Subnet Mask": 0.0.0.0, "Default Gateway": (nothing listed).

Background:  I have a Desktop (no brand) and the Dell D820 connected with a Westell Modem and a D-Link WBR-1310 Router.  Both computers work great connected to the Router with a cable.  Both computers are running Windows XP Home.

The only thing I can think of (and I'm remembering this from 2007 when I purchased the Laptop and had a wireless set up for a short while), is that the Modem and Router were bridged, which is not the case now.  Do they need to be bridged for the wireless connection to work?  Is it not necessary anymore and something called "Double Netting" or something like that is used...

Hpg61 Laptop Wifi Keeps Resetting Card

Jul 27, 2011

I had to send my HPg61 laptop in to check out a heat issue a few months ago. When it came back, I got a headphone jack issue (now resolved) and a Wi-Fi problem - I used to have great wifi from my bedroom to my parent's study which is where the modem is, even when I did have the heat issue, but when I got it back, that all changed.From my bedroom, my laptop would say "no connection detected" and had a red x over the wifi icon in the taskbar, but would have good connection if I were in the living room with it. This didn't last long - one day, the icon turned into a computer with a red x over it.

Upgrading Internal Wifi Laptop Card

Mar 5, 2013

I would like to upgrade to b,g and n so they will connect to all home networks more easily. I believe most of the b,g and n internal WiFi cards have three wires were all my laptops only have two.

No Wireless Networks Ar9285 Wifi Card?

Jan 26, 2012

I have read numerous postings on this and ather sites about the Atheros AR9285 not being able to see wireless networks - and guess what I have the same problem!My laptop is an HP CQ61-312SA upgraded to 4GB of ram, and running Windows 7 Home Premium, I have tried everything I can find on this and other forum sites with no luck at all, including updating drivers, making sure Wlan is started etc and I have downloaded programs like Xirrus Wi-Fi Inspector and Insider = both of which show absolutely nothing.I have one other problem that might indicate a software problem - on the odd occasion when my computer does try to connect to a wireless network it resets to a blue scree which states that it is doing a 'physical memorey dump' and then restarts.My Atheros card has worked perfectly for 2 years, but I managed to purchase another it case it was faulty - with the same results. I also upgraded the memory in case of a memory fault.Rolling back drivers and using system restore does not work and ipconfig/all gives identical readouts to others with this problem.
