cannot connect to tv from router

[John1,3]

had uprated wifi connected to replace previous, continual problems with roter connecting to tv, have tried all usual online tests , occasionally succesful, i must say had no problems with previous sky router, only since upgrade, have had 2 engineer visits but problem persists and no connection to tv for days at a time then works for a while , tv is fine just cannot connect apps, wish i had stuck with old sky broadband, no prioblem with that

If you have the new wifi 6 router change it back to 5 in the settings. I had the same problem and it's because my tv wasn't compatible with wifi 6
