My PC uses a TP-link model TL-WN722N (link to product below) to receive wifi from the router in the other room. I've been using it for about 5 months now with no problem, until about 6 days ago. My internet speeds from my PC drastically crashed from the normal speed of 15-20mbs download to about .7-1mbs download. The ping is unaffected but the upload is slower than normal ( not as bad as the download though). I've tried fixing the problem by: restarting routers, turning off literally all other devices that use wifi, uninstalling and re-installing drivers for the adapter via internet and original driver disc, changing USB ports, and changing the power-savings mode for the USB ports. None of these things worked out. Is there any advice/solution that anyone knows?

Update:It uses a 2.4 Ghz frequency, I apologize for not mentioning that.

I went to your link thnx..BUT i was looking for the frequency which is not listed. For example 6 gigahertz...
If you or someone near you has one of the new phones that uses 6 Gigahertz frequency then that can cause interference with your wireless device.
I never liked wireless cause it has intermittent problems.
Goto the manufacturers website or email them for info on that frequency.
the 150 Mbps is speed not frequency.
If in time you still have interference issues then you're going to need a way to figure out to shield your device from the other devices.
It may also be a grounding issue too. If your house or apt is not properly grounded. For example..when lightning comes around, do you sometimes lose electricity in the house?
