Wifi Stopped Working / Says Adapter Not Installed
Feb 19, 2011
I turned on the monitor (I had left the system running) and it said that it had recovered from an unexpected shut down. It didn't automatically connect to the wifi, so I opened the connections window to connect to a network and it said "Windows cannot find any networks." I refreshed several times and nothing happened. I clicked the option underneath "Diagnose why windows can't find any networks," and it came back with "This computer does not have a wireless adapter installed and configured." I then opened up the device manager, and under network Adapters, the only thing is "Intel(R) 82566DC-2 Gigabit Network Connection." I checked it out and it says it's working properly, and I believe that this adapter is for when you actually connect a cable directly to the PC.

The other day I went to a friends house, came back home, booted up my PC, and my wireless network adapter wasn't working. I've tried everything to fix it.It's a D-Link DWA-525 802.11n Wireless PCI netowrk adapter. On device manager it just says 802.11 Wireless LAN Card with a yellow exclamation next to it. And when I check what the error is, it's either error 31 or 52 at different times, depending what I've tried to do to fix it.I tried downloading the driver for it off the D-Link website, nothing happens at all when I install it. I tried taking it out of my computer and plugging it in. I tried enabling it and disabling it on device manager.I noticed one thing, when it's in my computer the green light at the back that says activity next to it isn't on.

my wireless connection has stopped working and won't repair itself.I have uninstalled it and rebooted my laptop (as suggested in a previous thread) but it's still not working. I have a Toshiba Satallite Pro L300 laptop.I went to the Toshiba site to find a download for the wireless adaptor but couldn't even find my model number on their system. I can get on the internet by plugging directly to the modem, and my internet provider suggests it must be the adaptor. I'm too scared to randomly download stuff from internet in case it is rubbish and mucks up my computer.

It may be a coincidence but my Broadcom Network Adapter 802.11g stopped working after trying to fix 'unknown device' in Device Manager (It was working perfectly before this).OS: Windows 7 Starter on 'BenQ Joybook Lite U105'.I tried the Windows Network trouble shooter and it didn't work (saying there may be a problem with the driver. I uninstalled the driver and re-installed it (including a possibly newer one) and it didn't work. Within 'Network Connections" the Broadcom wireless adapter is shown as 'disabled' I R-clicked to enable it, a window popped up saying it was enabled but it still showed as being disabled. My feeling is that something is preventing it from being enabled, logically, I would guess. Also went to 'Component Services' and ether started or restarted everything with the word network on it still no luck..My Google search on an other pc , now on day 3, couldn't find anything. (BTW the 'unknown device' which according to the icon, seems to be the joybook itself, is still not fixed and still listed as 'unknown device').

i have an Asus u56e that I recently bought a couple of moths ago. It has been a great computer until today when my wireless randomly disappeared for no reason. The wireless adapter has been disabled for no reason, and when I try to re-enable it, I can't seem to find it.

I currently own a Sony Vaio Laptop that has been working fine for the last 2 years, I was happily on facebook when all of a sudden, my laptop started lagging massively and it disconnected me from wifi, I was shocked to find that when I tried reconnecting, the laptop decided to stop working for a second and my wifi stopped working completely, every time I disconnect the Ethernet cable from my laptop even though my wireless switch is on, it won't even pick up my Virgin Media superhub I have about 5 meters from my laptop, it indicates that there is NO wifi anywhere, just the ascending bars with a big red X on it

I originally bought the 615 router because my Net Talk telephone required it. The first Wi-Fi device I used is my Kindle Touch. I have been able to use the Wi-Fi several times since I received the Kindle, but there have now been two failures to connect. The first time I just unplugged the router power and connections, restarted the modem, and rebooted my computer. The Wi-Fi then worked. Now I am experiencing a failure to connect again.
I have noticed that when I restart my computer I have to connect to the internet directly by pulling the cable from the router and putting it from the modem to the computer. This seems to teach the router what it is supposed to do, because when I reconnect the modem to the router the internet starts to work immediately.I have tried changing the password to wireless internet, but my Kindle still will no longer connect. The router is about two years old. [code]No go to the devices and check to see if you see the new SSID name you gave in the router. I should be listed there. Select it and it should ask you for a password, enter the password you gave in the router. The only problem is that my modem does not exactly say "mixed G and N".

when I couldnt turn on the wifi from the switch. It remained orange(which is its off state) and so I went to the device manager and the wifi adapter was shown there but with an exclamation mark. Showing the error "the device cannot be started(code 10)". So I uninstalled and rebooted, only to get the same error when it got reinstalled.

I have recently gone as far as restoring my computer to its "factory" state to try and combat this issue.
Unfortunately, I'm not sure there is much else I can do at this point - the issue has not been resolved.
I re-installed factory drivers for my adapter, then replaced those with updated drivers from Intel. I was 'alright' for a while, but have had to launch Device Manager to re-enable the adapter, or restart my computer entirely because it failed to display my adapter at all. At this point, I get no result with either.
I have tried to 'recognize' the adapter as a new device (added hardware), but that didn't solve anything - it duplicated it in Device Manager and then displayed the yellow exclamation point indicating it needed new drivers - I attempted to update but it displayed an error, so I ended up uninstalling the duplicate.
At this point, I feel like it's the hardware that is the problem, and not my computer's ability to recognize it. Though I have been able to connect to my network in the past, its ability to function would be patchy, at best, if I could get it to work at this point. Should I try to reset/replace my wireless card, or is there something else I can try?
My 'network card' is fine, according to a diagnostic, and my Bluetooth works fine.

I purchased a new built system, worked great 5 days, major trojan forced a reformat of drive. Now Win 7 64 Device Manager is empty- no network adapter found - I get the notice that "there are no properly installed network adapters". I use the on-board network adapter on the mobo, no plug in network card, hard wired to DSL -- like I said, it worked fine for a few days now it's GONE after reformat.

My laptop keeps saying "Windows did not detect a properly installed network adapter.If you have a network adapter, you will need to re-insatll the driver". I've found the right one and it still want install. Says it's the wrong one but i'm pretty sure it's the right one. I just did a fresh install where i put windows 7 extreme on a laptop and i can't seem to ge the right drivers i guess. I don't know if it's the wrong driver or a bad NIC Card.

I purchased an Alienware M17x R4 about 2 months ago and it was working perfectly until yesterday. After using it for a while, it disconnected from the WiFi, and after restarting the laptop I got a pop up message saying a physical WiFi adapter is not installed, meaning I can no longer use my wireless connection, but only a cord. Going to device manager, I did not see the wireless hardware on the list of network adapters (Intel® Centrino® Wireless-N 2230 With Bluetooth 4.0), however it is still listed for the Bluetooth. I have already tried reinstalling the drivers, system restore, dell diagnosis (which says there is no problem), AlienAutopsy (which also said there is no problem) and scanning for hardware changes from the device manager, none of this has fixed the issue at all.

To fix a bunch of other problems I've installed the 313NA firmware on my rev. C2 DIR-615
I can connect to my ISP and DHCP just fine, and I get DNS servers back just fine, but the DIR 615 doesn't serve DNS correctly for the devices on the LAN. If I set the LAN machines' DNS manually to the IP addresses provided by my ISP they can look up hosts just fine. With them pointing at the DIR 615 for DNS they get nothing.
When I attempt to perform a name lookup using the admin System Check -> Ping Test I get "Unknown Host". The same name lookup up by any other LAN machine using the same DNS hosts gets the correct result. I've made sure there's no caching.

having a problem with my Linksys wireless adapter: the light will flash a few times when I plug it in, then it will turn off. It won't let me connect to the internet or my printer.It's not the port: it is recognized when I put it in any other port, but it still won't connect. I think it's a virus, but my antivirus software isn't showing anything when I run a full scan (I use Malwarebytes Free). I'm gonna put AVG on a flash drive from another computer and try to use that later today, but right now I've been thinking that I might have to back everything up and reinstall windows.
-Windows Vista- Home Premium
-Linksys Wireless USB Network Adapter (I think it's WUSB600N, not sure though)
-Malwarebytes Free Anti-virus
-Netgear Router (I think it's WGR614L)

My router has been working for close to 4 years now with minor problems, just stopped yesterday, All my PCs lost wifi access and then when I looked at my Linksys WRT300N only the 4 Ethernet port lights were on. Unplugged plugged it again, I connected one of the PCs to the one of the Ethernet port, the PC is reporting that there is nothing connected to the other side. It's been 4 years already, I do have a Linksys wireless G router even older than this which is till working. I guess its spoiled, I don't mind replacing it

I have been using a d-link router for some time now and since yesterday it has stopped working ( I have an orange 'world' light on all the time) After looking around this site I have tried resetting etc and nothing works. If I plug the ethernet cable into the modem I can get on the internet if I plug the cable into the router then nothing. These are the details I got from the config all when I plugged the ethernet into the router.

Randomly my router stopped working in the middle of the night. I didn't think the issue was with the router so i called the Tech Support people from Brighthouse and they told me to connect directly to the modem so i did that and I had internet. But why would my router randomly stop working, I've had this Linksys Dual N bound router for a year and never had a problem with it. I want to think that its the internet providers fault but I guess I really don't know.

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.

My desktop was wirelessly connected to a router. It was working perfect, I did a wired connection from the modem to the desktop and when I tried to get the wireless connection again it has not been possible. When I try network trouble shooting I get DNS server might be unavailable. Been reading around and tried many of the things that I've read but none has worked so far.

I have been a loyal customer of a hosting company for over 10 years. The main reason I have a dedicated server is to eliminate those shared-hosting issues.For the past 4 years the service has been getting crappier. In fact; this week alone the ftp stopped working, mysql stopped working, and email.It is now to the point I have to move all my domains, mssql databases, mysql databases, email servers and countless files.I have been contemplating to set up my own dedicated server (Mac) and hook it up to my ISP. Most of the websites I host are local - only one or two are national/international.
