are these ok for the speed

Re: just upgraded to XL BB 20 MB
 

downstream power is too low i would say, but if your not having any issues then no need to call vm.

Re: just upgraded to XL BB 20 MB
 

what should the ideal downstream power be ?

Re: just upgraded to XL BB 20 MB
 

0 ideally -15 is mega low ..

Re: just upgraded to XL BB 20 MB
 

doing the speedtest getting various speeds from 12 mb to 18 mb - will monitor it and see how it goes.

Re: just upgraded to XL BB 20 MB
 

A low power level is an indication you are on the wrong tap in the cab and would need a technician. Jump on the newsgroups and they will book one for you, without the need to call up. Rather book it now than suffer slow speeds or connection drops.

Just make sure the modem doesn't have an attenuator on the back, between the coax and the modem. If it does, just take it off and see how the power levels are.

noticed the modem had an attenuator plugged in, took it out now get these readings

looks good to me

Re: just upgraded to XL BB 20 MB
 

Excellent, much, much better. You're aiming for -10 to 10 but the targets are different depending who you speak to .. -5 to 5 is a clear winner.

Re: just upgraded to XL BB 20 MB
 

Much better how about the Upstream.

Re: just upgraded to XL BB 20 MB

however doing the speedtest not getting a full 20 mb - getting from 6 - 14 maximum

Try this link and follow the instructions http://www.virginmedia.com/testmyspeed/manual.php

Re: just upgraded to XL BB 20 MB
 

Speed tests suck, download from
http://gamefiles.virginmedia.com .. get two fiels running and add the speed together.

lol beat me to it .. but that's cheating .. gone are the days of step by step :)

Re: just upgraded to XL BB 20 MB
 

Oh I have step by step for the same material but the link is quicker.;)

Re: just upgraded to XL BB 20 MB
 

ok

downloading 2 files

one file is 600 MB and second one is 1.1g

getting 800 kb/sec on first one and 600kb/sec on second one

Re: just upgraded to XL BB 20 MB
 

I think Moldova is your best bet here

Re: just upgraded to XL BB 20 MB
 

Around 15Mb


Around 13Mb


Is this connected direct or through a modem, if direct give Tech Support a call.

Tech Support is open 24/7 on 151 from your Virgin Media Phone. It's absolutely free.

Or call 0845 454 1111 from any other phone line.

Re: just upgraded to XL BB 20 MB
 

connected via the netgear 80.11g wifi router (new 802.11n should be here in 3 days)

tried again with 4 files

250kb/sec
247kb/sec
330kb/sec
400kb/sec

Re: just upgraded to XL BB 20 MB
 

Just multiply by 8 and add 10% for overheads and still around 13Mb.

If possible try a direct connection and run the test again.

Re: just upgraded to XL BB 20 MB
 

Do you see any packet loss ? As per the forum mods it is safe to send me your MAC address. Pass it over tonight and I will ask the network team to check out your connection.

Re: just upgraded to XL BB 20 MB
 

I have done a continous ping to smtp.ntlworld.com and getting these results

Ping statistics for 81.103.221.11:
Packets: Sent = 265, Received = 219, Lost = 46 (17% loss),
Approximate round trip times in milli-seconds:
Minimum = 13ms, Maximum = 64ms, Average = 26ms

Re: just upgraded to XL BB 20 MB
 

still not getting a decent speed - should go back to 10 MB as I was getting a stable 10 MB connection but since upgrading to 20 MB this afternoon getting 7-8 MB for the past 3 hours

Re: just upgraded to XL BB 20 MB
 

google DAP its a download manager or if you use firefox try flashgot. These are multi threaded download aplications that hit the site with more than 1 connection at a time. Then try just one download from game files and run it through DAP and see what speed you get.

I do not trust speed tests but of all of them ive tried this is the best one

Re: just upgraded to XL BB 20 MB
 

Start to look at your equipment and or your cabling. Is everything screwed in nice and tight?

How are you connected when you are getting this packet loss?

Re: just upgraded to XL BB 20 MB
 

wired connection, PC has a gigibit nic connected to 10/100 port on VM Netgear wifi router

last night around 1am was getting 19 MB this morning am getting 17.5 MB so improved

may be last night the network in my area was heavily utilised.

Re: just upgraded to XL BB 20 MB
 

doing more test using http://www.speedtest.bbmax.co.uk/ getting speeds from 5mb - 14mb

I assume my area is heavily utilised hence the fluctutation in speeds
