Regular drops for short periods

[roadrunner_68]

I have started experiencing regular drops on our virgin media cable. The down time can last anywhere up to 10 seconds. Often when it happens windows does not recognize the connection has dropped and some programs will remain connected. It is however enough to disconnect game servers and stop browsers from working.
I am new here so I am not sure what information you need. Here is the event log after the last drop.

Sun Jan 01 19:43:22 2012 Sun Jan 01 19:43:22 2012 Critical (3) Started Unicast Maintenance Ranging - No Response received - ...

Sun Jan 01 17:49:52 2012 Sun Jan 01 17:49:52 2012 Warning (5) DHCP RENEW WARNING - Field invalid in response

This two logs appear at least once a day, our connection drops once a day quite often more.
Any help would be great, thanks.

please post up power levels, 192.168.100.1... login (defaults are username: admin - password: changeme)... advanced settings below the 3 boxes... connection tab... copy and paste or print screen.

and is your VM Hub running the wireless network too? if so,

download inSSIDer (http://www.metageek.net/products/inssider/) onto a wireless capable device such as a laptop which connects wirelessly. Run the program downloaded above and let it search for all networks within reach of you.

Note the channel numbers each network uses, they will range from 1-13 then set your Hubs wireless network to use a channel that is not in use. Don't leave the Hubs wireless channel as auto, it sucks. 192.168.100.1... login... advanced settings below the 3 boxes... wireless settings.
