Since receiving a new router about a month ago the quality of my main channels(BBC, ITV and Channel 4) through the TalkTalk box has decreased. The picture on these channels are pixelated. With my previous router all channels were higher quality and no pixelation. I have also lost some of my radio channels (Classic FM appears but there is no sound). I have retuned three times without any improvement. Is this all connected to the router or to low internet speed which currently is around 10Mb/s which seems slow. You advice will be welcome as I am fed up at being unable to watch TV.
The picture on Freeview channels is not connected to the internet as they use the tuners in your TT box.
Could you try unplugging your aerial from the box and retune. The box will show no channels found but it will clear the box memory. Then try retuning again with the aerial reconnected and see if it has improved.
Are you in an area that has recently had a transmitter update requiring you to retune your TV and Box as a number of people are finding that their aerial is no longer fully compatible? I am in the Crystal Palace area and Freeview replaced my aerial free when they "upgraded" those transmitters.
You didn't say if you are in an area that needed to retune as that is causing a lot of these problems in those areas due to the frequency changes.

I'm trying to troubleshoot for you to eliminating the main known problems that may be causing it before going through other things which could be causing it. Do your pictures on the TV if you plug the aerial lead directly in to it pixellate as well?
If you plug the aerial back into the TV box, tune to BBC1 then Press the Blue Menu/YV button on remote > Settings > TV SignalQuality and what do the Signal Strength and Signal Quality readings show?
A retune never hurts. Take the aerial out of the box and retune. No channels will be found, but this will clear the channels from memory.
Connect the aerial again and retune and then retest.

I'm afraid that it sounds as if your aerial or hopefully just the aerial lead is the problem as you say that you get nothing on the TV when it is connected directly from the wall socket to the TV.
I am assuming that the TV is a digital, HD ready or full HD set and already tuned to the DIGITAL channels? It may be worth trying a retune of the TV on the digital NOT analogue channels with the aerial connected directly into it from the wall socket. If that is then picking up a good signal it is probably not the aerial. so report back please.
If the TV, directly connected to the aerial still doesn't give a good signal, I suggest that you try a new aerial lead first as they often fail and if this doesn't improve it you will need to get a reputable aerial installer in to check it all out for you.
OK well that's good news as you can now receive TV channels and it is not your aerial at fault, so we can now try some other things.
Could you please try the following :
Turn the box off, then unplug the power lead for about 10 minutes.
Re-plug in power lead.
You will then need to reset your personal settings (such as parental controls / ANTENNA OUT (blue button on remote > Settings > Picture and sound > Antenna out) / Surround Sound etc.) and also reset your scheduled recordings (might be worth taking a note of future recordings before doing this so you don’t miss any).
It is also a good idea to restart your router once you have done this.
If you do NOT have any recordings that you want to keep :
Blue YV /Menu button on remote > Settings > Factory reset. This option will re-format the hard drive and reinstall the system on your box and you will lose all recordings.
Either of these will confirm if it is the actual tuner in the box or a system fault, although obviously the full reset is better.
