I have an Archer T600U Nano installed on my partner's desktop PC. We have 100mbps internet in this house, which realistically translates to about 80-100mbps download and 20mbps upload speed on all the devices installed on it (my pc, her laptop, and both our phones).

However, while the upload speed on her PC is on par with the upload speed of any other device on the network (around 20mbps), the download speed is atrocious. Averages around 5mb/s but fluctuates between about 7 and 0.5mbps.

Running windows 10 home, and the latest win10 drivers from the TP-link website. Running on 2.4ghz wifi as the PC is just too far away from the modem for 5ghz to have a stable connection. Link speed says it's about 57mbps. I don't even care if the speed gets to 80mbps. A stable 40 or 50 would be fine.

Any advice would be appreciated

Thanks
