I have an MF286D router and a B535-333 router which I use as a backup for testing if connection issues are my end or network based.
Where I live is in a very rural area and of left to their own devices these routers will both connect to band 20 with a terrible download speed of maybe 3mbps - nowhere near enough for Sky Stream to function. If they lock onto band 3 the speed is great, but the connection is unstable and causes sky stream to have the video and audio out of sync by a few seconds. To get around this issue I force the routers to lock onto band 28 by disabling bands 3 and 20. Sky stream works perfectly almost all of the time and the download speed is around 15-25mbps - excellent. Bands 1 & 7 are both available but the routers very rarely lock on them as the signal isn't great.
Here lies the issue, when the either router is unable to use bands 3 & 20 the connection is dropped by the network at 9am precisely, every day. This does not happen when they are free to use any band. This is a huge inconvenience as everything in the house stops for about 30 seconds whilst the connection is re-established, teams meetings, computer updates, browsing, wasting time on tiktok etc.
Why does the network do this and more importantly, how do I stop the connection being dropped by the network daily at 9am.
MF286D running OpenWRT, B535-333 running stock Three firmware.
