OK as it turned out I had to set each PC’s DNS Server to the Virgin DNS addresses and reboot because although I had a network connection I had no internet on any PC now I have a painfully slow internet connection on all PC’s (albeit better than no connection at all) except my PC which will not save in the network connection manager and has decided in it’s infinite wisdom not to accept the terminal command gksudo nm-connection-editor
slowly losing the will to live
Try to set the DNS Server to OpenDNS IP adress (instead the router or Virgin nameserver) on the PC with slow connection:
208.67.222.222
or
208.67.220.220
except my PC which will not save in the network connection manager and has decided in it's infinite wisdom not to accept the terminal command gksudo nm-connection-editor
You could manually (as root) edit the stored networkmanager profile
sudo gedit /etc/NetworkManager/system-connections/"Network Emegra"
You have to edit it with root permission … you can’t even read it as anyone else
the above command assumes the connection is called Network Emegra … and will need adjusting if it’s called something else 
BTW, you REALLY need to get into the habit of not using spaces in names in Linux … it can handle them, but it’s easier if you steer clear of them
ok this has got to the stage where I can’t even describe the problems I’m having anymore, but to try to sum it up after setting all PC’s to static IP address and setting the DNS Server settings to the router IP address left me with no internet, I then had to set the DNS Server to the virgin DNS addresses which give me an incredibly slow internet connection an all PC’s except this one which give me no internet connection at all because it wouldn’t allow me to change the settings because of a bug that happens to affect this PC and no other even though I used the same installation disc to install all PC’s, and in addition to that it has decided it doesn’t want to let me access the network editor in root by not accepting the terminal command “gksudo nm-network-editor” , anyway the incredibly slow internet connection rapidly turned into no internet connection at all on any PC or laptop (that hasn’t even been touched) suggesting the the router is now screwed up so I reset the router to factory defaults expecting to to get the default network showing up (as virginmedia8286556) but instead I get Network Emegra (the connection I created) so explain that if you can, but at least it lets me post this message.
So I’ve had enough I’m not gonna try to sort this anymore but I would like to thank everyone whose tried to help me with this especially Mark whos perseverance and patience goes beyond the call of duty 
Many thanks
Graeme
I haven’t much experience with the Superhub … but normally to do a FULL reset, you need to hold the reset button for about 30 seconds
Some routers even require that you turn OFF the router, hold the reset button … then turn ON the router whilst still holding the reset button for a few seconds.
But if it’s working…
See above for a workaround for the one that won’t let you make changes in networkmanager.
Networking remains somewhat of a black/mysterious art (in Windows too) … even though it shouldn’t be :o
Did you try the openDNS servers ?
Another suggestion may be to try putting all PC’s back to how they were … just try a static IP (with the openDNS server) on the slow one … as SeZo suggested.

Ok I’m sorry if my last post come over as a rant and to be honest it was but it wasn’t meant to imply ingratitude and I’m sorry ,
I’ve had a few beers tonight and i’m just so frustrated with all this I’m going away on a weeks holiday from Monday and spend some quality time with my grand-daughter so it’s probably best left till after that, please don’t think i’m being ungrateful, I think computers have a habit of bringing out the worst in people and I suppose I’m no exception.
Many thanks for all your help (Mark & SeZo)
Graeme
Dunno where that came from … I never thought for one second you were ungrateful … I know you better than that (Mr Thankaholic)
If we don’t chat before … have a great holiday
If we don't chat before .. have a great holiday
Thank you Mark I intend to
I had another go at setting static IP addresses to the PC’s and Laptops this morning and I’ve finally managed it, I’ve used the openDNS addresses but then discovered there is no facility to set these addresses in the superhub Archived - Virgin Media Community
so the question is, is there any point in me using openDNS am I gaining any benefit or am I just making things worse, I’ve set the dhcp pool to 100-254 as you suggested but I still don’t know how to give the printer a static ip address.
Many thanks
Graeme
The PC’s will just ignore what the router is doing and get their DNS service from openDNS
What’s the make/model of printer ?
What's the make/model of printer ?
Samsung CLP-325W
Dunno if this is possible somehow in Linux … but in Windows you use an application called SetIP
see page 34 here:
But once the IP is set it doesn’t matter what OS is used … so you may have to use a windows PC to set the static IP.
If you haven’t got a Windows PC, let us know and we’ll see if there’s a way to do it within Linux.
On most printers it can be achieved on the printer itself, by use of the configuration buttons … but samsung seem to have had a brain fart moment where Linux is concerned :
SetIP (for Windows) can be downloaded here:
http://downloadcenter.samsung.com/content/SW/201108/20110811153648878/SetIP_V1.05.03.exe

There is a method of using SetIP in Linux.
If you go to page 36…
IPv4 setting using SetIP Program (Linux)
Well spotted SeZo … shows how lazy I was feeling earlier, just 2 pages further on :
@ Samsung … I apologise for my earlier comment
I have a Windows 7 installation so I can use either Windows or Linux whatever you think is best or easiest
Unless you know where to find the SetIPApplet.html file … probably easiest to go the Windows route with the executable above.
Ok I’ll download the .exe and let you know how I get on
Many thanks
Graeme
Well to get back on track I’ve set all PC’s on my network to static IP and everything is fine except for the offending PC which is still only giving me around 1 mbps download speed, we’ve covered a lot of ground on this without success so is there any point in pursuing this any further, because I don’t want to waste anybodys time
Many thanks
Graeme
It would be handy (now) to see how a LiveCD/LiveUSB compares.
Here’s an idea … is this system simply at the boundary of it’s resources ? … with the web browser open and running the speed test … whats the output from:
top
hit Ctrl+C to stop top from running, so you can copy/paste the output.
also what’s the output from:
free -m
Also run whilst doing the speedtest
Also the same outputs whilst downloading something may be informative too
Ok heres the top output while running broadbandspeedchecker

Wait for the transfer to start … then you’ll see something at the bottom of the terminal similar to:
36% [=============> ] 46,725,881 937KB/s eta 94s
What’s the figure I’ve highlighted red ?
Ctrl+C should end the transfer … as should closing the terminal.
