We have the 1GB internet and it works great except in the upstairs bedroom. Anytime we try to stream HBO/Hulu/etc it will play and then start buffering after a few minutes. We have a wifi extender and the signal strength is “very good”. It’s not the device because we’ve tried it with Apple TV and Amazon fire stick. I ran the speedtest and the first time I got .07 mbps and then a few minutes later 12 mbps. Has anyone else had something similar and know how to fix it?
