Yes, you’ll have to pick up a cheap router, but any $50 gadget, such as a Mikrotik RB or Ubiquiti ER-X will do. Most network techs have a garage full of castoff routers they can pull out in a pinch.

Yeah, I should have included that in the initial email, apologies. I've plugged my laptop in (Lenovo T14) and it
exhibits the same behavior. I've even plugged in my travel router which works pretty much anywhere I've tried it, and
after some time, the same thing happens.
