When we moved house, my machines were sent to a spare bedroom, rather than the dining room. The net router was downstairs, so clearly inconvenient for wired lan. I bought some TrendNet wireless adaptors, (Wireless N PCI Adaptor modules), fitted them, switched on and all seemed fine.
A few hours later, there was no connection. The router looked normal, my wifes laptop worked fine, but my machines were incomunicado. Rebooted and it seemed to fix things - for a couple of hours.
This was a year ago. I have been dogged by this problem since then. TrendNet say the problem is everywhere but with their cards. My wifes laptop if sitting on my desk upstairs, has no troubles. One of my machines has been upped to Windows 8, but the problem has not changed at all, (the others have XP).
I am about to bin these cards, but thought it might be worth asking here. What could be wrong, can I fix it?
