Freeview channels gone wierd since setting up broadband

[FranB1971]

We've just set up sky broadband. An engineer is coming to link in the dish thingy in tomorrow so not got skyQ as yet. 

I can get prime, netflix, YouTube as normal on the TV via broadband but the freeview channels have gone wierd. Instead of channel 3 being ITV, channel 4 being Ch4, channel 5 being CH5 etc I've got BBC news on channel 4, BBC red button on channel 5 & all sorts of radio channels from ch10 onwards instead of the normal ones.

I've restarted everything after turning off & on again. I've returned too. Surely all freeview should be the same if doing it through our normal ariel?

@FranB1971  Having broadband installed has no effect on Freeview channels received via an aerial unless you have a New TV (bought in 2024)with Freely?

It also not linked to Sky Q (where you originalyl posted this)
