Remote Wakeup EnabledNot sure how i could debug to identify the root cause. Any thoughts? I am running Kernel 4.9.111 with rtl8812AU drivers as a module.

Im using a TP-LINK Archer T4U Bus 004 Device 002: ID 2357:0101
on fedora28 4.16.13-300.fc28.x86_64
For the most part, the device works great with this driver. But over ssh sessions, I get lag every so often. Im trying to figure out whats causing it.. The server im connecting to has a really good connection to the internet and at home, ive got a 100Meg connection.

the wireless connection looks good, but I see dropped packets

thats over the course of about 10 minutes or so.
Any ideas?
actually I just noticed that Im connected to the 2.4Ghz side.. How can I force it to connect to the 5Ghz side?
