I am running Vista on an Acer Aspire 4530 with an Atheros AR5B91 Wireless network adapter. I used to get 2 bars of signal strength and suddenly the connection would go off and on. That was about a month ago. Now I get nothing at my normal spot, but if I sit right under the D Link router, I get 5 bars. We tested a Dell side by side and he got 5 bars to my zilch. He also tested his IPHONE - it worked. He tried a wireless dongle and it overheated.
I uninstalled the adapter, and rebooted, then set the power requirement not to save power.
Any help wpuld be appreciated - with thanks
