From my limited knowledge of the ntl side, I think that looks ok. Only bad when you see T3 or T4 timeouts. But I could be wrong.

[Richy99]

what area are you in? you might be in an oversubscribed area

[Nedkelly]

What ype of modem do you have look on the bottom it wil say ambit 100 / 120 200 silver modems 250 is the blue modem 255 256 black VM modem

[Hom3r]

you may have an old modem
you should have QAM256 not QAM64

[DancingBrave]

I thank you all for taking the time to reply

i have the black modem virginmedia 255

rm8 area

[Hom3r]

What SW version is the modem on http://192.168.100.1/CmInfo.asp (Cable Modem Information)

what data rates is the modem using http://192.168.100.1/CmOpConfig.asp (Operation Configuration)

some areas haven't been upgraded to the 256QAM yet.

[Hom3r]

is you modem left on 24/7?

If so turn it off for a couple of minutes, QAM64 may be you problem

[DancingBrave]

I allways turn it off at night because my last modem used to overheat and when the guy from virginmedia came he replaced it and said its best to turn it off at night so i do,

ok i will turn it off now what does that 256qam do is it better than my qam64

Right quick update guys

just before i get disconnected from a online server my send light flashes very fast and thats the only one that flashes ????

still same qam thingy ????

QAM64 /256 isn't a choice that can be reset by a modem reboot- it's the scheme of modulation that a particular network uses. Virgin Media is not one uniform network, but an amalgamation of many smaller local networks that have been created at different times, using different hardware by different companies. Gradually over the years, the number of independent local cable operators has diminished as smaller companies were bought-up by larger ones. The final stage of this process was when Telewest, NTL and blueyonder were consolidated under the re-branding called "Virgin Media Broadband" early last year.

QAM256 enables more bits per symbol to be transmitted, but is more sensitive to noise than QAM64, so requires better quality cabling and hardware in order to be reliable, hence some older parts of the ex-NTL network are currently not up to using it (e.g. Peterborough: ex-NTL > ex-ex-Bell Cable Media system is still utilizing QAM64 - and I don't have any particular problems with it, it works okay most of the time...)

[DancingBrave]

I understand now thank you

So what should i do then ????

[JenJen]

What is the mac address of the modem? I can run a diagnostic test to it, which will confirm if anything is causing intermittent connection. If there is a fault you can get a technician booked to sort it out.

[DancingBrave]

do you want me to pm you it or type it here
