    Why do I lose wifi signal while I'm on the phone? If I'm just using the handset for browsing or downloading or whatever, the wifi signal is strong and constant at both my house and my parents' house. If I make a call, however, the phone almost always loses wifi and can no longer find the network... until I hang up. Then it picks up the network just fine... until I make another call. I cannot get it to stay connected.

    The weird thing is, the phone will detect all other networks in the area when I'm making a call, but once it loses my home network it can no longer find it until I hang up. What's going on?

    A CDMA phone (ie, Verizon and a few others) can't concurrently access phone and wifi.

    That isn't true at all. A CDMA phone cannot access voice and data over a CDMA network at the same time. You could talk all day long on your phone and browse the web using WiFi if you wanted to.

    OP, your most likely problem is that WiFi is set to turn off when your screen turns off. When you are making a call, there is a good chance you are holding the phone to your head, which the proximity sensor detects. This turns the screen off to save battery, it also knocks your WiFi out.

    To fix this, press menu>Settings>Wireless & Networks>Wi-Fi Settings>press menu again>Advanced>Wi-Fi sleep policy>choose Never. That should fix the problem for you.

    That was actually the first thing I checked, and it is already set to "Never." Is there another possible solution?

    I see you said "almost always" disconnects. What type of security do you have set up on the router ie: wep, wpa, hidden ssid? I'd try turning off all the security features and see what happens. Also, how old is the router? Some routers aren't compatible with the power saving features built into newer wifi chips, and will cause you to drop connection.

    I said almost always because I don't always check, and because it's not an immediate thing (so not all phone conversations are long enough to shut it off). The wifi will last for a minute or so after the call has started before shutting off.

    One router is about a year old exactly, the other 2-3 years. Both are wireless N and both are LinkSys. I think they're something like the WTR320N and the 620N, or something like that. Don't know the exact model numbers off the top of my head.

    I guess the power saving compatibility issue sounds like a possibility... The wifi works just fine and never drops signal if I'm not on a call.

    Don't forget, though, that once it drops the wifi the only way to even DETECT the network again is to end the call. It will pick up any signal but the network I was on until I end the call. Then it finds the network and picks it right back up again.
