[SOLVED] Download speed slow via wireless usb adapter

[syynnh]

See, the problem is that since yesterday, after a restart, i noted that my internet was significantly slow, went to speedtest.net and yup there it was, from a solid 50 mbps download speed and 10 mbps upload speed i went to 1.5mbps download speed and the same 10 mbps upload speed.

A short term solution i found was to go to device manager, and uninstall my network adapter which is the USB TP-LINK WN8200ND V2, after i uninstall it i have to reset cause there is no internet, after that restart the download speed goes up again to 50mbps, but then if my pc suspends/restarts or simply turns off and then on, the problem comes back, from 50 mbps to 1.5 mbps.

I tried to reinstall the drivers, the latest one and the one one before, and nothing seems to work , not even restarting the network from the router or windows config, also cmd commands doesn't help.
I would be very pleased if someone could help me solve this, thanks

If nothing else has changed, i.e., your ISP isn't throttling your speed, I'd suspect a failing adapter. I recently replaced the one in my laptop and discovered that the old one was such a piece of crap that the antenna terminal had come off the circuit board.
