wireless working but doesnt find my own network...

[zeca]

Hi, I have a strange problem with my wireless, I have the broadcomm bcm4312 802.11b/g LP PHY installed, and it can see some wirless networks, of my neighbours etc, but not mine (its not a problem of my network cause with other computers I have no problem conecting to it...)

I set the connection manually and it was working fine for a long time...until someday it stopped, it was after I had to shutdown the computer with the power button for a few times,
cause I had some problem with the display...

Anyways, right now I can see some wireless networks, but not mine, and even the manual setup isnt working,
I tried to reinstall the firmware and so on but so far no solution.

Any ideias ??
