WiFi stopped working. What to do?

March 13, 2010 at 16:59:41
Specs: Windows 7
My laptop is connected to the internet by Wireless Connection/WiFi, the WiFi was working just fine last night but ever since this morning it hasn't worked. I tried rebooting it, even bought a new wireless router and it still won't work. It found several other wireless routers but not the one that I'm using. When it's connected to directly connected to the router, it works fine but when it's not, it doesn't. I don't really know what to do, I'm extremely confused. And I've been trying to figure it out for over five hours now. If it matters: the laptop is a HP G61-429 Notebook and runs Windows 7.

In light of what you've done and tried, I suspect the issue is the wireless interface in your computer.

Check in Device Manager to ensure it's working properly. You may will also want to ensure you have the most recent drivers for that interface.

If it's shown as working in Device Manager and you have the most up-to-date drivers then the issue may be corrupt files in the TCP/IP stack. If that seems to be the case, uninstall the TCP/IP stack, reboot and reinstall it.

If it's still not working, you may need to replace the wireless interface.

How would I reinstall the tcp/ip stack?

& To replace the wireless internet, I would just have to buy another card?

I forgot to mention that the Playstation 3 & my friend's cell phone wouldn't pick up the WiFi signal if that matters.

The fact that you bought a new router and tried it made me think it was the wireless interface on your computer. Considering your PS3 and friend's cell phone aren't able to connect has me wondering about the router.

At this point I would suggest you reset the new router to it's factory defaults. I would then connect it and configure the wireless on it without using any encryption. Use a different SSID from what you used originally. Can you connect?

If yes, then it seems like your new router is indeed working and I would then enable WPA encryption and setup a complex password for the WLAN and I would then connect the computer to it.

I'm not quite sure how to reset the new router. Or what A SSID is.

It's even more confusing because the computer I'm on now is connected through the router.

I reset the router and got it to work for a brief minute. I went downstairs to tell somebody, and came back upstairs and it was disconnected. After clicking it again, it connected. But not with full strength. Which was fine. I shut it down and went downstairs again. I came back upstairs to do something and turned on the computer to find out if it was a fluke. I turned it on and the connection could not be found in the room. So I moved closer to the router and the connection appeared but it wouldn't connect. =/

Edit: Also.. the laptop was taken to somebody's house with wifi and it worked so it's got to be a problem with the wifi. (Netgear WGR614 v9)
