Do Routers Affect Internet Connection Speeds? [RESOLVED]

[Kezmondo]

Hi,

I have recently setup a wireless network at home. At the moment, this just consists of one PC and the following:
- Cable broadband (1Mbit)
- Netgear WG311 wireless card
- Netgear WGR614v5 router

All went fine and connection was established and I can access the internet. However, it seemed slow. To eliminate wireless issues, I disabled the wireless card, and reverted to a "Wired" setup:
- Cable modem connected to router over ethernet
- PC connected to router over ethernet

But I am still getting the slow speed.
Running the test at http://www.adslguide.org.uk/tools/speedtest.asp, I get download speeds which vary from 30-80 KB/sec, where I would expect the full 125 KB/sec. If I bypass the router, and go straight from PC to modem over ethernet, I get that 125 KB/sec.

Am I being harsh here? Surely with a wired connection, the router should not degrade my connection speed like that?

I've upgraded the router to the latest firmware, and tried restoring factory settings etc...still no joy.

Any thoughts/comments gratefully received.

Thanks...
