Never had this problem before, it just started happen. Latest firmware (8.0.0) is installed. Didnt change any settings. My wireless signal is excellent but my MBPS varies alot, goes to 18, 24 and as low as 5.5. MY SIGNAL IS EXCELLENT. I have tried changing to every channel but it doesnt seem to fix it. I have reformatted my computer using Vista and XP and it still does it. I am using a Linksys wireless PCI card. Latest drivers. WPA encryption. I have even tried repositiong the router. I am out of options!
