Slow speed on Linux laptop

I am having the same problem as the linked threads. My internet speed on my Linux computer ranges between 6mpbs and 12mpbs. This is ONLY the case on my home network. I have run through every Xfinity troubleshooter, changed Linux distro, and replaced my computer's WiFi chip. The speed was great up until very recently.

Thanks for reaching out @phiboy! I completely understand wanting to see speeds above 12 Mbps. A step you can try now if you haven’t already is connecting your laptop directly via an Ethernet cable (CAT6 or higher) to the modem or gateway and run a speed test. This helps confirm whether the issue is strictly WiFi related or affecting the connection overall. 

 

Was the WiFi chip replaced before or after your started to experience slow speeds?
