When I encountered the problem, I stopped using WiFi with my laptops and desktops, and went with wired Ethernet. The problem is that, in my apartment, I'm surrounded with a large number of WiFi access ports (probably routers) so the sources of interference are out of my control. I don't think you have THAT problem, from your description.
Background: both Bluetooth and 2.4 GHz WiFi share the same frequencies. So does your microwave oven. Some portable phones (not just cell phones) use it, too. Lots of opportunities for cross-interference.
That is what I do. My main computer is hardwired. I have other devices that use WiFi and don't have any apparent problem with internet connections. Newer routers are sort of like automatic CB radios. When they boot up, they will scan for a vacant frequency and then lock in. I think it is unlikely a $100 router will change frequencies on the fly...
Thanks, but I don’t think this is an interference problem, as the Bluetooth works fine if I use Edge for the browser. Also, the problem is recent. I’m just not sure if it started when I started using the EcoCarbon speaker (which was ok at first) or if it started with a recent Windows update.
My smaller Dell laptop has no problem (identical placement of laptop, router, and bluetooth speaker.)
And last, I’m already using the 5 GHz band on the wireless router with this :-)
At this point I’m suspecting some arcane browser settings.
