E71 bugs when connected to an Ad Hoc wireless network

[t2sa]

Hi,
My new E71 works quite well, the only major problem I have is that I can't connect it to any Ad Hoc network. More specifically, I can connect it to this kind of network but when I try to open any application that require internet, such as VOIP or Opera, the phone just shut down and restart. If I don't open such an application, the phone end-up shuting down anyway after a while. The phone works fine with a common wireless wifi connection
and with Blutooth.
It's pretty annoying, meaning I'll have to buy a router for no reason. Has any one experienced this problem yet?
Thanks in advance,
Timothee

PS: I had the same problem with two different Ad Hoc networks, made by two different computer.
