I'm currently on XL BB and I'm wondering what other Virgin media users class as an acceptable level of drop off in download speed. Day after day I see the same drop off in speed, tech support think there is no problem:

According to google 20480000 bits/sec = 2.44140625 MB/s. To me an acceptable level would be around 2/3 of the maximum, which should be around 1.62 MB/s

These are the figures from the last day and an half (four simultaneous downloads, two from fuller.zen.co.uk/test and two from gamefiles.virginmedia.com)

Are you hitting the STM limits?

No STM limits hit, Upload always around 700 kbps

Looks like an oversubscription issue to me, judging by the times the dropoff is happening. The test at 12:13 today is appaling, if it's still going on I'd contact support either by phone or on the newsgroups.

Have you posted on the Newsgroup? My speed is slow, I posted my modem logs and signal levels. Now a tech is coming round to boost my signal (or some such).

Basically I've been having issues for ages now and in February I was told by VM, that the capacity problem with the UBR I'm on will be resolved on 19 April 2008 (subject to change). Then I got told the problems had been resolved by re-routing on the UBR, but my issues continued to happen. So I got back in contact with support, basically there answer to me is:-

"Tests on your connection do show that around midnight the SNR level had
dropped although this looks to have been restored around 2 AM. None of the
other checks show any issues with the connection"

"Checks show that in the last 24 hours, the downstream was hitting maximum
for less than 30 minutes, and is currently not hitting the trigger for us to
raise as an issue. Once it reaches a certain threshold, then it triggers a
warning to the networks team to start the upgrade process, this trigger
point is lower than what we use to raise the issue, and as yet there are no
dates as to when they will be implemented. At this time there is ample
capacity on your connection, so utilisation issues would not be causing you
a problem."

Yet, someone who lives less than half and mile away from me on the same UBR, gets this response:

"I have made a change from our side to see if we can make any improvement to your connection. Please note that whilst there is an issue on your UBR you may continue to experience issues with your connection until this fault has been resolved.

UBRs have 24 cables, each with a number jof upstream channels (I think it's four) problems tend to be cable specific or may only effect certain upstream channels. Whilst you near neighbor may be on the same UBR they will almost certainly not be on the same cable. It is likely the change made to you neighbour was to change the upstream channel, though this tends to be temporary as the automatic load balancing is likely to swap it back.

does not even show up on the status page which i find strange
just phoned the support line and a gent there said the isuse had been FIXED , and there are testing in we should be getting normal speeds in a 2 to 3 hours 9we will have to wait and see

what?
30-03-2008, 13:39
just had a check up on it for you.
the issue is not resolved. still logged on the internal status page.
the initial fix time was set to 26th march which has obv now been passed with no updates on expected resolve time.
it has been assigned to another department as of the 25th and with them you will find that it can sometimes take weeks - occasionally months - for ubr upgrades to go through.

I seem to get around 15mb during peak and full 20mb off peak.

Doesn't bother me, still allows me alot due to the full upload speed i always retain.

Acceptable - NONE! Put up with it you will, I downgraded to the 2 meg service and ever since it has been absolutely rock solid, always get the full 2 meg (at least 95% anyway).

I just hope when the upgrades are done later this year that the 2 meg tier remains. :)

Ufitm,

Yep, still got problems. Tech visit last Tuesday, no faults found from what he can test (modem, cable for kinks etc) and he passed it on to his manager, who has rang and is currently arranging for more tests to be done at my connection point and in the street at a local level.

Back to the UBR, the original date given to me for the fix / upgrade was 19 April 2008 (even though officially VM have told me the UBR issues have been resolved, but `what?’ above says differently from what he can see on the internal status page) and my reduced monthly charge was agreed with the 19th April as the resolved date, so VM have another 10 days or so before another letter or phone call goes in for even more money off.

Plus as the BT exchange is 24M ADSL2+ enabled now, I might be ordering it or 8M ADSL Max. 5.5Mb/s constant day or night + stable latency with a neighbour over the road with BT, so I'm guessing ADSL2+ will give around 17Mb/s (although I'm not really that concerned about download speed, more interested in stable connection for gaming as it is my primary use for the connection). But it all depends on what package I can find on a one month rolling contract because when cable works it works well, so I'm reluctant to switch totally away from it.

Even though I’ve given VM more than enough time to fix the problems. It will be nearly six months to the day from when I first reported a problem via e-contact (that’s if it gets sorted out next week on the 19th April). I’ve noticed that there isn’t a lot of planned maintenance for April on the VM website http://status-cable.virginmedia.com/vmstatus/maintenance.do.

Don't hold your breath. Mine's been an utter nightmare with speed issues. These people have had me jump through hoops, format my hd, are you running p2p software?, it's a virus, are you sharing your connection? blah blah blah. They finally admitted 3 months back that it was utilization, gave me a date of April 2nd for a software update to fix it all. I rang last night to ask what had happened to the fix 'cos it was as bad as ever, and guess what? It's not been done. They said it's being done today. I've tested it and it's still useless.

When I was on 512k it was great, the free 2mb upgrade hasn't been worth a light. Like you I play one or two on line games. Clearly with this connection I can't do that.

Don't worry I'm not holding my breath, otherwise I'll would have been dead a long time ago. May be that's what's wrong with my connection, it's been holding its breath. Quick call 999 and get the paramedics or is it the police I need for daylight robbery. :D

Snazzy,

When VM do get round to doing the work, please post back with the results good or bad. It would be nice to know if the local upgrades fix the problems.

Laters,

Laters,

It's meant to be fixed as of today. I told them I'd give them another two weeks before I ring again. I'm gonna sign up for WOW for a month again and see how it plays. I'll post back in about two weeks.
