I have an older 04:00.0 Network controller [0280]: Intel Corporation
Wireless 8260 [8086:24f3] (rev 3a) on a Thinkpad X260.

I also have multiple Access Points broadcasting the same SSID in my
house, and yes, I experience those issues often when I move from one
part of the hose to another. I have, however, also experienced it in a
hotel when I was using the mobile hotspot offered by my mobile, so that
was clearly not a roaming situation.
