So on wired you see 1MB/s download and on WiFi you see 5 - 6Mb/s. Ok.
Open up cmd (I'm assuming your a Windows bod).
type "ping -c 100 www.google.com"
Let it trundle through and eventually it will display a summary. If the packet loss is exceptionally high then bin the router and get another.

Make sure you laptop and the router are working at 802.11G speeds (54Mbps), if it's fluctuating wildly try updating the drivers for your wifi card, flashing the router to the newest firmware and changing the channel the router is operating on.

Even assuming you're running with max security turned on (WPA) and allowing for that speed hit a 54Mbps wifi link will outpace a 10Mbps inet link.

Not familiar with the telewest service, but I use the same wireless router. When you say "straight into ethernet" do you mean you've tried using an ethernet port on the back of the WRT54G router (i.e. Telewest > WRT54G "Internet" port, then either WRT54G's "1" to "4" ports > Computer's ethernet.) If that is working OK, then you at least know it's a a wireless issue.

Security is WEP and yeah if i go straight from the modem to my laptop / desktop i get downloads of 1mb/sec without a problem , if i use the wirless i get 500-600 kbps max

done the ping , packet loss seems ok there was 0% lost and ping speeds were around 31 ms

i downloaded the latest firmware last nite , will upload that to the router 2 nite

What i meant was when i remvoe the router and run the modem via ethernet straight to my desktop / laptop i get the full speed , when i run it via the router i get 500 - 600 kbps downloads

If he's on 802.11b at 11mb that has a 50% (ish) overhead so you only get a 5.5Mb actual useable throughput which might explain the numbers...

Sounds like 802.11b connection - you need to check the spec of the wireless card in the laptop. If its 802.11g then check the properties to make sure the driver is set for auto speed or 802.11g and hasn't been limited to b only
