Hi! Noticed this was a recent thread and I think we are having a similar issue.
I just moved places, I brought my xfinity equipment with me and it booted up without a hitch. The internet works fine on my laptop and my phone, however, my desktop is a different story.
My issues are:
Slow browsing speed
Momentary disconnections/reconnections (I only notice these if I'm playing a game or remote accessing my work computer)
I've tried different browsers, using an ethernet cable, different DNS, along with flushing the cache. I've updated all my network drivers - still the problem persists. Speed tests reveal normal, if not great, speeds.
There is one thing though - when I use my work-provided VPN, browsing is lightning fast. My internet can still disconnect while on my VPN, but nevertheless the browsing is apparently normal.
I'm know very little about networking, but could this piece of evidence help arrive to a solution?
