Windows 7: WiFi speed down from 300Mbps to 54Mbps??

WiFi speed down from 300Mbps to 54Mbps??

For my laptop, the speed was 300Mbps few days before but it changed to 54Mbps last night. I did not change any settings for my router and adapter and the only software I installed during this period is Windows update of March. I found the client monitor in router's setup page displays 802.11n is disabled. So what are the reasons?

Thanks in advance.

P.S. I've got the adapter driver to be the latest one.

Question, what router are you connecting to? Is it a personal or public router? How many other users are connecting to it?

on the other computer that is connecting wireless, are you having the same issue? If you are, the router could be failing.

Do you have the same connectivity issues while connected to other wireless connections?

Are you sure that no one else is connected to your router? Maybe change the password to something very complex and see if the issue persists.
