I have a Dell Inspiron 1720 laptop and up until Saturday I've never had any problems with my WiFi.The adapter I have built in is the Intel Wireless WiFi Link 4965AGN. Every other computer in the house is having no problems at all and is keeping the connection.I am having issues and it's not software related since I was due to backup/reformat the hard drive anyway, I did that to speed it up. What's happening is it will connect for a few minutes and then all of a sudden NO networks will be found. Not mine and not the twenty others I usually see from the neighborhood. Then, after a bit, only mine will show up but it won't connect properly. It'll just give me a local connection and no internet. If I reload the drivers and reset the computer it works again for a bit and then does the same exact thing.Does this sound like a bum WiFi card? Something else?

did you disable power saving? Mine used to do something similar. It would go into 'low power' mode while I was reading a page and ultimately drop the connection.Also try older driver set.And finally http://shop.ebay.com/?_from=R40&_trksid=p3907.m570.l1313&_nkw=Dell+Inspiron+1720+wifi&_sacat=See-All-Categories

No go on that. Tried all tips I've found on the Internet.I guess I find it odd because it works perfectly fine for like a half hour and then just drops and can't ANY networks for a while and then works fine again.

You'll laugh, but it could honestly be interference from another device, e.g. a microwave or cordless phone. Use a site survey program like NetStumbler to see what channels are in use around you, then switch to one that isn't as busy.[Edited on September 21, 2010 at 12:27 PM. Reason : ...]

I'll give that a try. The only reason I'm skeptical of that is that every other laptop in the house holds connections no matter where they are.I did disable the Bluetooth adapter and just did a Ping and Speed test and that seems to have helped with the down speed and so far I haven't dropped a connection. I wonder if the Bluetooth channel was interfering with the WiFi card -- but I can't wrap my head around why that would happen after three years of having no issues at all...
