Tmobile home internet suddenly doesn't play nice with work VPN
I have been reliably using TMHI for the past two years. I have a secondary Unifi Gateway and AP for the home network. I have been using a pi hole for the past several months. Last week, I suddenly can't stay connected to company resources via the main VPN tunnel. I can kind of use the older VPN. Nothing to my knowledge has changed.
I have tried the usual troubleshooting steps of restarting all the components. I have removed the pihole from the equation. I have also removed the unifi network from the equation in my last troublshooting attempt.
For the most part, i still get solid 100+ speeds download and 40ish upload, which is unchanged. I seem to notice that i am having to reload webpages more often, as they only have load or load without formatting, or not at all. Sometimes a speedtest will hangup completely. I have done multiple packet test and nothing ever seems to get dropped, just latency gets quite high (500+).
There are no hard wired connections available to my house, so my only alternative is Starlink. I have considered the external antenna, but I'm skeptical that it will solve my problem.
Does anyone have any experience getting TMHI to play nice with corporate vpns?
