    Good afternoon,

    I'm experiencing very bad WiFi performance with Sony T13 (Atheros ar9485wb). I have clean install of W7 x64 and it happens with both - drivers from Sony site and most recent (10.0.0.75) driver from Atheros site. Power Management for WiFi adapter set to Max Performance.

    There are a few issues:
    1. Signal strength is not the best - I get 3 out of 5 bars in about 20-30 feet away from the router. Although problems below exist even if I stay next to the router

    2. There are intermediate disconnects every so often that lasts for a few seconds or even minutes. Adapter does not disconnect from WiFi but download process completely stopped. At this moment I can see in the router that laptop stopped communication.

    3. Even when it's connected, download speed is terrible. I get only 50KB/sec copying the file from the server in my local network (another server connected via gigabit ethernet).

    Never need to say that other wifi devices don't have the same issue. Wonder if either of you have the similar issue.

    Thank you very much.

    Try out this once:
    Disable the Bluetooth device and check if this improves your WiFi.
    Because it has a small overlap with WiFi, it can sometimes interfere (depending on antenna's / gain / channels / etc).

    I solved the problem by switching the router to another channel. It was another neighbors WiFi with very low signal on the same channel. Well, as I said, it's very interesting that Sony was the only device out of dozen I have that had an issue.

    Thank you!

    Yeah I realized this one too and wanted to update my post about this one.

    But you were faster :)
    Glad you figured out.

    I've a WiFi-scanner on my Android phone which gives great overviews of WiFi channel usage and so you can select the best channel yourself.
    Great piece of tooling in case of issues...
