My 17" iMac can not seem to get a decent download rate! Using speedtest.net I get 65KB/s (kilobytes, not bits) but on my PS3 (also is connected via wireless) and PC I get between 160KB/s and 200KB/s. My PS3 gets less signal strength as well but it is still three times faster so I am thinking that maybe there is a problem with my iMac's wireless card or is is this just normal for Mac's? If this is a problem is there anyway for it to be fixed? Any help would be greatly appreciated.
