Router slowing internet

Hi.



When I use the internet just through the usb modem the connection
is fine. However, when I connect through my router (wired or
wirelessly) the connection speed appears to be drastically reduced. I
used this router for 6 months without any problems. I returned it and
got a replacement but the problem still exists.



I did a speed test I found and here are the results. Any help would be greatly appreciated.

This was done yesterday... I did another test today and the download speed was around 6kb/s. Below is a test I did when just plugged into my USB modem.

I am in the UK using talktalk.net. The router is a Linksys/cisco WAG160N.
