to try and answer most of the questions:-
the 2 routers have different SSID's
they are on different channels [in original post]
the 2 pc's/routers are completely seperate, no bridging.
pc 2 does work when connected over cat 5 to router 2 [in original
post]
both are winxp platforms
both had dhcp servers running [range 192.168.1.100-149]
In my earlier post I mentioned that I had tried dynamically
configuring the wireless connection IP and this had not entirely
worked, i.e. the wireless icon stated that it was connected but from
the PC i could not ping the router IP, well I have got it working now,
I switched of DHCP on router 2 [which I did not do initially], I can
now ping the router [192.168.1.1] over the wireless connection. A
further complication was that once the wirelss connection was up and I
can talk to the router I then have to setup a VPN connection into my
ISP as this is my corporate broadband, this did not work until I
enabled RIP on the router.
I am happy that I can at least get connected now even though it is a
static address I have configured, I have read loads of posts however
which elude to the same issues with Linksys routers and Dell laptops
not acquiring DHCP addressing.
