All of those links seem to redirect to other pages, but I have been through those different forums looking for solutions and sometimes while the situation matches, the solution does not resolve my issue.
CachyOS’ wiki has a dedicated Post Install section that I have following to configure the regulatory domain, but even after configuring, I am still stuck at 20 Mbps. (I cannot link to the page, but if you look up “Post Install | CachyOS”, you should find it)
As for firmware/kernel alignment, I have verified that I have the corresponding versions for both, but also it should not be a problem since Cachy is easy install.
For the AP compatibility, I am using Xfinity’s XB7 gateway. I feel like this could possibly be an issue since Xfinity tends to really lock down their gateway preferences, but I am leaving calling their support team as a last resort.
Maybe you could resend the links and I could verify if I have tried the solutions there. Also thanks for the welcome!
