Since nobody has actually definitively stated that it works for them: I've just tested mine and I can successfully access machines on my LAN. Admittedly I'm running RISC OS rather than Linux, but it rules out an issue with the actual Pi hardware/firmware.

Googling hasn't helped me so I assume the issue is isolated to mine. But just can't see how hardware could cause such a specific network fault.

Assume the Pi runs some kind of base firmware tho? Like a BIOS. Wonder if there could be something dodgy there

Indeed, it does seem very strange! Like you say, there must be some sort of "firmware loader"; I believe that there's a firmware image on the SD card but even then it needs to know how to load that in the first place.

Can you post the output of the following commands, when run on the Pi:
ifconfig
netstat -r

Also firewall can cause this, what do you get from:
/sbin/iptables -L

Yep. Will do this tonight when I get home and post back. I rebooted it remotely before and it hasn't come back online (sometimes gives me a card read error on warm reboot)

Had a quick scan of this thread again, couldn't see if you had said if you could ping devices or not.  The implication in a lot of what you have written is that you cannot - but the assuming something is the mother of all cock ups so...

Can you ping your router?
Can you ping any other device on your LAN?
Have you tried to force a IPv4 ping? (e.g. ping -4 192.168.1.1)

Look normal.

What happens when you ping SFDDWRT1 using (1) name (2) IP address ?

Pinging SFDDWRT1 works fine. That's the router.

Have you tried a traceroute to one of your LAN hosts?  Does it fall over at the Pi or the router?

When you say:
Cannot ping LAN hosts from the Pi
Do you use name or IP address, if only name try IP address

If name it successfully resolved IP from hostname, but fails to ping.
If IP - fails

The plot thickens.

There is another windows host on the LAN presenting the same symptoms (One I hadn't tested with) as the Pi.

Hmm, that's curious. I'd look at your switch. got another to swap out temporarily?
