Wifi issue

[jcpety]

Hello everybody

I updated my QTEK83O0 with WM6. Everything works fine.

Unfortunately, WiFi can't work. It detects the SSID, then I can press
"connect". But nothing happens: no connection; no error
SpAddCert.exe doesn't work and I canot update HTC CommManager.
My modem is in mode b and g.
My laptop can connect, so the issue must be related to the phone.

I really need help.

Any ideas?
