Verizon/Qwest single end-user difficulty vs Xfinity

Sat Mar 18 21:06:52 UTC 2023

Verizon does weird stuff with traffic in their cell network. Like wireguard
only running 1-2 Mbps over Verizon but faster on fixed like providers. I'm
assuming they rate limit certain protocols to avoid bypassing their
streaming video rate limits. I can see 200/30 Mbps on a 4G speedtest but
VPN runs very slow still.

Xfinity is better than cellular so I'd switch back. Any fixed cable, fiber,
wisp, or fast dsl provider should be better and more stable.
