Head Tech just left, all seems good.

TiVO down to 44 and 47 also.

Got a free V HD box on the way to replace V box. Also he installed a SuperHub as you can see.

those power levels are perfect but it isnt because of the shub

upstream modulation has changed

Shouldn't you have your modem and router next to your PC monitor?

Mine is in between two PC monitors.

personally I'm cautious with signals being transmitted so close to other electrical devices

why? They can be wherever you want them to be. Any device connected to the router can be up to 100m away from it so it could be down the street for all we care. If you got a couple of switches in on it you could link all your neighbours together :)

changed a few things around not near monitors now lol.

Will have to keep an eye on the levels. Checked an hour ago TiVo box downstairs was up from 44 to 51. TiVo upstairs was up from 47 to 55.

I'm out now didn't have time to check modem. My modem is upstairs.

Had my superhub enabled today to check if they had fixed the constant unstable upstream and jitter issues to no avail absolutely nothing has changed. Then phoned back to get VMNG 300 registered again to be told by someone from the UK that they wont activate it a prompt argument i hung up redailled got india and had it done No problems. Cheers VM

Latest power levels.

Can someone explain to me about the levels to going up and down does it allways happen is it normal? Does it affect your service connection.

are your TiVo's doing the same? if the upstream power is crawling up then disconnecting then its too high, but to me looks like a fault, going from 48 to 55.

Do you know where you cabinet is? is it open or have visible damage, or has it recently been refurbished? It could be that an amplifier has been replaced hence your power levels going up, noone can really tell apart from a VM engineer

Yeah TiVo upstairs comes off the same splitter as Internet so super hub levels are exactly the same as TiVo. Super hub is upstairs. The TiVo downstairs is going up from 44 to 51. So far I haven't had any disconnects on internet or break up on TV channels. Just the levels are pushing borderline just checked TiVo upstairs and it's 55. I also have a V box downstairs haven't checked those levels though, but no break up of channels.

I've got a powered amplifier installed plugged into electrical socket in living room.

The levels through the day are going up and down.

Posted a picture of my VM cab on page 5 it's in bad shape. There being upgraded this month the cabs according to VM and some cabs have been upgraded in Newport. Tech said the cab door won't close properly because it's too full of wires and outdated. He also said all the connections are water proof. I've reported the box to VM.

no idea really, is the small cabinet fed from a bigger one? Ive attached a picture of my cabinet, the drop cable from my house goes directly to the cabinet, so I have no idea what your small cab is. It must stem from another cabinet, but I dont know whether its just a splitter or anything more??

It sounds to me like the engineer putting the plug in amplifier was a bit of a bodged job, to cover up a more serious equipment fault somewhere in a local cab, whether thats aged, or damaged or what, I dont know. Maybe if you could get a photo of the inside of the tiny cab that may shed some light on what the setup is and maybe shine more light on your issue. Sorry I couldnt be more of a help

Checked TiVo upstairs before I left house at 9am was back down to 47.

There's a lot of these small cabs dotted around the streets by me, then there's one main big cabinet about a 2, 3 minute walk from my house (looks like that one in your pic Craig)

I haven't experienced any problems yet with disconnects or break up on TV channels. Just hope it's all good now and maybe levels going up and down will be sorted when they upgradethe cabs. My area is due the speed upgrade in July this year.

Thanks a lot for your help.
