For over a year when visiting a relative who has no Internet, I've been able to successfully connect to a nearby Xfinity hotspot with no trouble. Lately, however - maybe the last 3-4 weeks - my phone will connect like always to the hotspot but after a period of time (15-20 minutes) I lose Internet connectivity over wifi. Today, I brought my laptop with me to try and pin this down some more (I'm better troubleshooting on Windows than Android) and the same exact thing happens. Can authenticate and connect to the Xfinity hotspot but Internet drops very shortly.
Sometimes it will sporadically go in and out for a few minutes, and pop up a message that it failed to obtain an IP address, and then a few minutes after that it will connect but say that the Internet may not be available, and then no browsing at all. (DNS_PROBE_FINISHED_NO_INTERNET)
Or, I can't browse a site directly (DNS_PROBE_FINISHED_NXDOMAIN) but I can get to it via Google search. I tried the things listed here and still no help: https://errorcodespro.com/error-code-dns_probe_finished_nxdomain/
This only happens when I'm visiting him - I have absolutely no wifi issues anywhere else, including Xfinity hotspots, with either my phone or my laptop. I have Performance plan so should be covered that way, right? My relative has no other visitors with Xfinity credentials, or at least any who might have noticed a drop.
I've run out of things to troubleshoot. Could it be that the public hotspot on the closest Xfinity modem/router is flaking out? Who knows where that could be - it's a multi-unit dwelling. Is there a way to permanently "forget" that particular router and hope there's a different one nearby?
Any tips much appreciated - thanks!
