This is a problem that i observe regarding the Indicated wifi speed on the 'status' dialog box (Windows 7 operating System). I have a TP-Link wifi-n enabled router. The box indicates a connection spped / maximum speed of 150 Mbps(small b). on my status dialog i do see a speed of 150.0 Mbps listed. However on certain other PC's (All Win7) I see speeds as low as 5 Mbps. Why does this happen? How will this Affect performance? how may this be rectified.
