Hi guys,

I have an Acer Aspire One A110AB (bought new in late 2008) - I've since upgraded it Ubuntu Netbook Remix 10.10 (Maverick) and I'm having lots of issues with the wireless, it seems very flaky and unreliable.

I have been told to post the following info to aid in finding a solution (sorry if I've done this wrong, I'm no expert with Ubuntu)

If nobody has a suitable solution, i'd probably just buy a USB wireless adapter - any recommendations?
