Battling with channel 121 !!!

[dunkyd]

Comes and goes. Pull out smartcard. Phone them repeatedly.
What do I do now ???

 

[Rickster]

Check your signal quality and strength.

Works fine by me

 

[Captain Beer]

What error message are you getting?

 

[dunkyd]

E16-4 error message……came on for a few hours yesterday so we left it. Off again today. Done all the resets etc. Their lady phoned but not really any help.
We are on a special package with the estate we live in. Others in my street have the same problem so it's not wiring or signal strength.
