A few days ago my friend brought me his wifes Toshiba laptop that they're letting a friend use saying they couldn't get it online wirelessly. Using my DSL, I got it online & updated some programs & then decided to try my USB wi-fi & had no problem getting it online. Fine. It was returned to their friend & last night,(a few days later), it was brought back because no wi-fi. I went into device manager & see an exclamation mark on the Intel(R) PRO/Wireless 2200BG Network Connection I did re try my USB wireless flashdrive & it don't work on the laptop BUT works on my tower fine.
