Slow Speeds in SA1 area of Swansea

Welshchris · 02-03-2009, 00:07

My connection is really slow tonight and also having problems with timing
out and pages only loading part way.

I have done some speed tests on speedtest.net and speedtest.io and i get between 4 - 7 mb out and of 20mb which is appauling. Also on gamefiles im getting a max download between 4 files of around 545kb/s.

Ive been having problems on and off for weeks now its really starting to take the micky now.

You can add Southampton and London to your list ... My 10M is down to 2Meg.

its really starting to take the micky now. Virgin Media are gonna find themselves in deep trouble again soon if this carries on with a lot of people.

The above power levels are fine, so the speed issue may on the uBR.

Did you report this to VM prior to your newsgroup post?

Any packet loss?

Russ · 02-03-2009, 09:54

I'm sure there's a recorded message on the tech support number about problems in SA1 (other than the area being an over-developed eyesore

)

i did yes, and when i woke this morning my connection speed was still only 9.7mb and i posted again on the newsgroup and by the time i just came back my connection is now 19.2mb.

Funny that isnt it. I stand by what i said in a post previously on here Virgin Media are intentionally limiting connections when they shouldnt be.

Whats the best way of checking for packet loss....?

I was just looking at this..... and i tried it

http://homepage.ntlworld.com/robin.d...tips/loss.html

the netstat -s -p tcp command was first i tried and on that site it says any highter than 5 retransmitted and there r problems....

TCP Statistics for IPv4

Active Opens = 874
Passive Opens = 400
Failed Connection Attempts = 3
Reset Connections = 229
Current Connections = 19
Segments Received = 71591
Segments Sent = 62769
Segments Retransmitted = 266

Mine was 266 retransmitted.

I wouldn't go to the ISPA with that theory, there's no proof there at all and I can assure you it's not the case.

Just as a thought, there are probably 'a few' 20Mbit customers sharing your downstream with you, along with all the 10 and 2Mbit customers. In my case there are a total of 400 customers sharing the 38Mbit with me. Doesn't take many people using it at once to slice 10Mbit off.

I think you just saw a loading spike which took you to 9.7, someone was having a damn fine leech session. All it would take is one 10 or 20M customer to stop what they were doing and you get the 9.5Mbit back.

this has been happening for weeks, modem reboots, and when u mention this to them it suddenly returns. To much of a coincidence.

Ignitionnet · 02-03-2009, 15:06

But you're the only person I've seen complain about it sir.

If the modem is rebooting repeatedly that suggests a problem with the modem, not the network. There is no need for Virgin to reboot your modem to mess with the traffic.

Welshchris · 02-03-2009, 15:17

i have reported this to them and also posted on here what they tried claiming was wrong. They said it was Auto UBR balancing and that it was changing channel and thats why modem was rebooting and thats total nonsence. Virgin Claim there are NO! problems yet why is it when i do get the problem and report it within 2hrs all is well again EVERYTIME. Thats much more of coincidence.

My dad has also had slow internet and random reboots of his modem in Swansea this weekend. Maybe its an area thing where Virgin Media are not admitting to as they usually do.

Welshchris · 02-03-2009, 15:46

i wouldnt put it past them Chris.

Ignitionnet · 02-03-2009, 16:19

Or maybe it's a fault, dodgy modem power supply, dodgy more, whichever.

As I said Virgin will not be randomly rebooting modems on purpose. If they did reboot your modem you'd be able to tell from the event logs.

Welshchris · 02-03-2009, 16:48

but what ur telling me is complete rubbish as what im telling u has come from Virgin media support themselves. They said that it IS todo with them.
