TP Link Nano adapter connecting to network but no internet
I recently bought a nano adapter for a old gaming desktop I was trying to connect to my network in a room without eithernet. I was able to successfully set up the device and it worked for a day but after everything updated (60gb) it shows connected to the network but wont get data. The rest of my network is fine so I wonder if my AT&T gateway has stopped connection to the desktop because of the excessive data use. I've looked into the settings and don't see anything wrong but I'm new to messing with settings so I'm curious if anyone has any advice.
