My daily random ramblings
Sounds like you have got a lazy router. I am no engineer but I suspect that a brand new router might solve the problem.
That's what we asked for but no joy. It seems it may be a line problem instead so just waiting for it to be resolved.
Although I am quite used to talking to myself, any comments on my posts are very welcome, provided they are not abusive. I do reply to them so please check back. It's good to talk (!)
