With my Wifi if the signal strength is less than 50% it and i search for a signal i get No Wlan found but if i walk closer to the router (within about 10 feet) it will find the signal and i can then walk back to were i was before and abit further and keep a signal (although it may be week) But whatever i do the furthest from the router i can be is about 20 feet before i lose signal compleatley . is this normal. is there any way to improve it. thanks

I get a maximum of 30 feet at home with it, it seems to be a common problem with the phone.

My wifi signal and stability has improved with the upgrade firmware from N80 to N80ie...

No real problems ... not great and easy to lose connection - but I am a long way from the Router without complaints!
