I hope someone can really help me with that.
I had many problems to install my wifi TP-Link Archer T2U Adaptater on Xubuntu 18.04. After long time searching the internet I found a solution that upgrading my kernel to the brand new version 5.0.5 could solve the problem and it was really solved.
But a week ago the upload speed of the adapter decreased a lot. The Download it's ok I'm having problem only with upload.
Look what I've already did:
filimm@avaris:~$ lsusb Bus 001 Device 002: ID 8087:8000 Intel Corp. Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub Bus 003 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub Bus 002 Device 006: ID 0cf3:3004 Qualcomm Atheros Communications AR3012 Bluetooth 4.0 Bus 002 Device 005: ID 5986:0652 Acer, Inc Bus 002 Device 004: ID 0bda:0129 Realtek Semiconductor Corp.

- I have Windows installed on this notebook and there it's working like a charm!
- I have an Archer C7 router 2.4/5GHz and I've already tested disable the 2.4GHz
- When I use the 5GHz band the download is ok and upload is poor but when I use 2.4GHz band is the opposite the download is a shame but the upload is FASTER than using 5GHz (yeah, I know it's crazy)
filimm@avaris:~$ uname -r 5.0.5-050005-lowlatency
I can give any information you want. I just can't understand how it got slow from nothing.
