Have wireless “4K” boxes, main box cannot maintain 1080p while watching sports. Slow right down and lags out while degenerating down to 480 and pixelated to hell. Have reset modem multiple times and box multiple times. Internet speeds are great and are testing at correct speeds, so I either have a faulty box or the box can’t even give us 1080p which wth it’s 2019 what is Shaw going to do to fix. (Bear in mind I have already powered on and off multiple time)
