Hey, the got the LG Marquee and I have been battling trying to get the groove ip working and it's finally working ok, but only if I'm in the front room where the apple air port extreem router is. I emailed groope ip that my google talk on my mac book pro works great in my whole house but my phone with groove ip only works in the room with the router and they said,
"Phones generally have weaker antennas than a laptop would. If it's working while you're near your router but gets worse if you move away that means the phone is losing signal and the network is being affected. Nothing in the app is really going to be able to help with that. If you add a WiFi extender or something that should help with the phone connectivity."
I have a small single story 1200 sq ft house and a wifi extender seems a little over kill. I used the speed test app in the room where groove ip does poorly which is only 25 feet away and I'm getting 9.2 megs and 13.10 megs where the router is. Is there another cell phone that would have a stronger wifi signal?
