I've been having an issue with my laptop losing it's wifi connection. It's a Dell Latitude D630, WinXP, 1.8 Ghz and 2GB memory. I bought a new router and that seemed to fix it for a couple days. Now i'm back to losing my connection randomly again. Any other suggestions?
This may not be a PC or a router problem - instead, it would be the connection to the ISP. Are you in a position to use a cable for a while to experiment? If not, you need to keep an eye on the router's LED lights to see if the DSL flickers or disappears at times.
