Are there any how too's on more advanced wifi problems?
I can't seem to find anything offering up help on more advanced wifi issues. This isn't move the router closer, reboot the router, check the cables, get a faster ISP type stuff. I have 1GB fiber and I can't seem to get certain Apple products to work. They are all connected to the same Wifi but like my iPad and new MacBook Pro work fine, anywhere in the house even right next to the products that are having trouble. My iPhone, iMac, Apple TV and Mini HomePods all connect and show good signal, but then drop off, and at times REALLY drop off, like 900-980mbps down to like 20-30mbps. My google chrome cast works fine as do my Amazon Echos, so it doesn't make any sense why it would be only certain Apple products. My place isn't big enough for it to be a distance or interference problem, but I don't know what else would randomly effect only half the Apple products I have in my place.
I have an AT&T BGW320-505 router with 1GB fiber.
Any ideas? any how to's anyone can point me to for troubleshooting?
Thanks in advance!
