I got problems connecting my iMac to the internet (Wifi). Signal is fine, all other machines (iPad, win pc and macbook pro connect just fine).
read several posts about that issue but couldnt figure out anything.
i just found this suggestion:
"config t firewall amsdu" http://community.arubanetworks.com/t5/802-11-Client-Device/New-iMac-802-11n-issues/m-p/14505#M283
where do I use that commands or do you guys know any other solutions?
E: just read about 2,4ghz routers and bluetoth issues. when BT turned off the internet works again, but very, very slow. maybe another issue?
best regards, Alex
