Been getting this issue myself. Reported 3 weeks ago and still not resolved. Some of the guys on here will be able to offer you some good solid advice but don’t expect an answer over night.
To speed this up, I’d copy and past your router status stats. Connect to your router 192.168.0.1 but don’t sign in, click router stats and copy and past all the information from it to here so someone can look at here.
