the IP address on computer 1 is 192.168.1.2. This router also connects to the internet.
The router on computer 2 is connected to the router for computer 1 and CAN connect to computer 1 and the internet.
I am however unable to connect to computer 2 from computer 1 and I've no idea why.

What you have is
x.1.n -> router (x.1.254) -> inet
x.88.n -> router (x.1.254) -> no where as it doesn't know how to find x.88.1
Why do you need 2 sub nets anyway? If it is for a vpn then the tunnel will handle it better.

Surely the IP address of the router is the default gateway for the network?
Could you give me an example of what I need to do? I suspect my other router has some built-in software to figure out the correct route which is why I'm not having any issues with that one whereas the Thomson one clearly needs some extra manual config. Really appreciate you taking the time out to help me on this one.
I need two subnets simply to emulate a work environment in my lab setup.
Cheers

2. in order to router from one subnet to another you need some info on the subnets, and importantly HOW to connect to both of them
So for the pn router on .1.n it needs to know how to connect to the .88.n subnet, so you either need to specify the gateway to get to it, or add a .88.n ip address to the router.
Now you have setup a route to .88.n via .88.1 but is .88.1 connected to the router? If not then there is no way it can route to it, as it doesn't know how to connect as the default route (0.0.0.0) doesn't route 192.168 addresses

Computer1 (can connect to the internet but not computer2)
|
Thomson Router (192.168.1.254) ---------------------Internet
|
|
|
Routerboard Router (192.168.88.1)
|
Computer2 (can connect to computer1 and internet)
There is a static route set on the Thomson router to the Routerboard router (192.168.88.0/24 192.168.88.1* LocalNetwork 0 UP [UP]) - see below
What have I missed?
Thanks again

if you traceroute from it to computer 1 (and viceversa) post the results here.

The routerboard needs to have a WAN address in a different subnet to its LAN , so that it can ROUTE.
You're probably best to give the Routerboard a static WAN address in the 192.168.1.x subnet. Then set the gateway on the static route ( to .88 subnet ) to that IP.
Finally you may need to add some port forwarding on the routerboard, since any attempted connection to computer 2 will be seen by it ( the routerboard ) as an incoming connection and likely blocked by any firewall

Tracert from computer 2 to computer 1:
C:\Users\Administrator.BC>tracert 192.168.1.2
Tracing route to W2K8DC1 [192.168.1.2]
over a maximum of 30 hops:
1 <1 ms <1 ms <1 ms router [192.168.88.1]
2 <1 ms <1 ms <1 ms W2K8DC1 [192.168.1.2]
C:\Users\Administrator>tracert 192.168.88.2
Tracing route to 192.168.88.2 over a maximum of 30 hops
1 83 ms 99 ms 99 ms dsldevice.lan [192.168.1.254]
2 * * * Request timed out.
MisterW, there isn't a problem routing from the Routerboard so I'm pretty sure I don't need any additional static routes. Let me know if I'm wrong here though!

It looks like the traceroute doesn't go via the 2nd router, so have you set up a route on the .88.n router to .1.n ?
It looks like the .88.1 router "knows" the route to the .1.2 box and ignores the .1.254 router to get to it.
It should be
router .88.1
router .1.254
pc .1.2
Which is what is happening with the 2nd tracert. but it doesn't go to the .88.1 router.

My guess is that router 2 is getting its Wan IP via dhcp from router 1. In this case it will be able to route outgoing requests fine but router 1 is trying to route to the .88 subnet via the LAN IP of router 2 not its WAN ip
