    Hi
    I had already posted some details about changing original WiFi card to a different one where I can get 5GHz working on Win-7.
    Now I have tried few more cards to check and the outcome was not much helpful so need some expert advice.

    Originally the laptop has Atheros AR5B93 card, which works fine on 2.4GHz on Win7 and Linux Ubuntu, no probs.

    I did put another card Intel 5100agn, while the drivers were installed on Win7 but kept giving “Error Code 10” – means cannot initiate the card, but the same worked while booted in Linux. - - No solution found to make it work on Win7, I guess I would blame the card as it was pulled from a Dell/HP machine, cant remember now.

    Tried another card – Broadcom BCM4312 – which was supposed to be %GHz as well as per Broadcom site but it would show only 802.11b in Win7 and wouldn’t even work on Ubuntu – outcome – useless…

    Tried one more card Realtek 8187B, the datasheet as per their website shows it fully supports 802.11 a/b/g, which means 5GHz as well. Downloaded the latest driver, Win7 shows the drivers are loaded in device manager, with no errors, but it wont find any network (yes, the antenna was connected). Downloaded the utility from Realtek itself with the drivers, but the utility would say “no Realtek Adapter found” – how stupid when Device Manager does show the card is installed and no errors, not even that yellow exclamation mark nothing… and finally Ubuntu wont load that either.

    Any help is appreciated for why the adapter (RTL8187B) would not pick any network, not even 2.4GHz or 5 GHz?

    Initially for a moment I doubted that Acer Aspire might not support 5GHz band but that was not the case when I used Intel 5100 card and Linux could use my 5GHz band (not Win7 though)…

    Any help for Realtek RTL8187B?

    Thanks
