Re: New Modem

downstream is good though. Unless your connection is starting to drop I wouldnt worry about it.

Yeah I guess still no disconnections was a slight break up on sky movies HD the other day but didn't come to anything.

Hopefully these changing power levels will be sorted when cabs are upgraded.

Re: New Modem

HD channels have started breaking up again today :( It's happening now with Thor on Sky Movies Premier HD. It was happening earlier this morning as well on sky sports HD 1.

They have been fine the last couple of days watched all the master golf on Sky Sports HD 1 no problem at all.

Re: New Modem

Did you check your levels when it was breaking up? When I had issues with picture & broadband it was always when the levels dropped very low.

Re: New Modem

I have just literally finished watching Thor, great movie. I love his accent. I can't wait for The Avengers to come out.

The levels aren't stable they jump all over the place they go from 47 to 56 in a few minutes. Then from 56 to 47 again in minutes. This is happening all the time.

They change a lot.

Re: New Modem

Not so good, touchwood wood after they fitted an active splitter for me downstairs mine been fine and Tivo box and superhub (in modem mode) been happy and working ok with no break up of signal or disconnects of the broadband.

Hopefully you will get an engineer out and fit one for you and sort it out for you.

I had 3 techs out last week.

They fitted a powered splitter a few months ago. There must be a fault somewhere. I'm no expert but maybe I need a re wire to my house or there's a fault in the cab that feeds my house.

The break up is happening on both my TiVo boxes.

funny looking pit

They have small green boxes even with pits here is pits and there is one of those across the road

Engineers I was told don't have access to some cabinets in a pit area only networks, as the small cabinets in a pit area are main termination points for the phones and or amplifiers rather than taps. Because the taps are underground.

Only queried it because that cabinet looks a bit small to house the various taps for different attenuations as well as the amp and telephone terminations as well.

And from pics the cabinets are normally a lot higher and wider

Re: New Modem

Just had the head tech for my area here. He changed the active splitter and put all new connections on the wires leading to it.

Hopefully levels willl stay roughly the same now.
