Or tell them provide a router that works for free or you're leaving, and they'll send you one for £0.

You could also try speaking to the Social Networking team on Facebook or Twitter. I got on to them about my wireless problems etc and they arranged the superhub 2 to be sent to me free of charge on the first instance ; no further questions asked.

Worth a try :)

When the networking people have sorted this channel out the issue will go away for SH2.

When a SH1 locks onto the offending channel, IMO there will be some performance effect but that will be somewhat invisible because the channel has at least been acquired.

What I've said above is my extrapolation from what I was officially told by VM.

Hi Sephiroth,

Being a bit cheeky here, but it's been a few weeks now, I've asked for an update on the VM support forum, but they always take an age to reply to anything.

Do you know if this issue has been resolved yet? I don't want to contact VM CS until I know it's been resolved as they will probably just send me out a SH2 regardless telling me it's fine (cynical, but I know that's a likely outcome).

Also you mention about performance drop if a SH1 locks onto the channel, does this only affect upstream or will it affect downstream (I only ask as I am getting 50Mb regularly with the SH1 when I was getting 60Mb with the SH2)

Cheers

Hi Gonzo

I've asked the man at VM about resolution of the issue with the CMTS.

As regards the performance drop, generally if upstream has problems, downstream is affected because upstream sends ACKs and other commands to the download source.

So how is the updated shub ?

I've stuck with the ntl250 modem/ 20MB so far as its rock solid and never given any problems - wasn't convinced with all the reported problems from the shub. Is it worth updating ? 20MB seems to be enough for me, but I'm paying for L Broadband for which i should be getting 30MB really. I'm going to have to renegotiate my contract soon, so now might be the time.

I'm not interested in the old Shub, gather i'd have to upgrade to 60MB to get the new one ? It must be reliable for VPN as I work at home a bit. Is it still best to use Modem mode with the Shub2 ? If so would my Netgear WGR614 router be ok for 60Mb ?

If it ain't broke ....

yes, that's been my attitude so far. Even so, don't like paying more for 20MB than some are paying for 30MB.

The old superhub is still perfectly adequate as a modem. I wouldn't dare use it as a router but as you're currently using a modem only (and presumably your own router), then it wouldn't be an issue to swap out the Ambit 250 for a SH1 in modem mode.

That said, the SH2 is a much better device than the SH1. I have had zero issues with it but again I keep it in modem mode.

ok, thanks - i'll think about it ;) Also depends on what retentions offer when I give them a bell soon. Is it unreasonable to ask them upgrade me to the shub/30MB for free seeing as I'm paying for it and getting 20MB (and I'm a cable customer of 17 years)

I don't think that's unreasonable at all, especially as you say you're paying for L as it is. In fact, I'm surprised you haven't got an option to do that automatically in My Virgin Media.

Thing is if you're on the legacy frequencies, when you go onto the bonded frequencies, they may well be more congested. If you post your modem stats, we can have a shot at deducing whether or not you're on legacy frequencies.

Think I'm on the old system which is very reliable, and gives a consistent 20mb. Maybe I'll just stay as I am.

Don't be so contrary, Qasi!

8 channels on the overlay/overbuild frequencies are better than 4 for reasons well understood - except where there is saturation and then it makes little or no difference. In this case the OP may well be enjoying an uncongested frequency range. These are the realms of the bleedin' obvious.
