F5D7632-4 - Belkin Router Will Not Hard Reset

I recently rescued an old Belkin 54G router (Model: F5D7632-4) which I planned to use as an extra wireless access point towards the back of my house where I have some dead spots. I logged in on the Belkin's IP: 192.168.2.1 And went straight to change the IP and put it onto the same subnet as my router. I changed it to: 192.168.0.1 as I had it in my head my router was .254 My router is 192.168.0.1 so obviously this didn't do much and I couldn't access either device.

I unplugged my network and plugged directly into the Belkin to change to another IP and I cannot access it. The operation times out. I can access the normal router when I connect back up to the network fine. To solve this I decided to reset the router. The instruction manual for the Belkin says a momentary push on the reset will do a quick reset. while >20 seconds will perform a full hard reset. Both of these are signified by the power light flashing, and the reset is complete when the power light becomes solid again.

Unfortunately no matter how long I hold the reset button for, the light does not even blink and no reset happens. Obviously this may just be a dodgy reset switch, the router is getting quite old, so I will go in an short the reset pins by hand if I need to. The solution I am looking for is either to reset so I can start again - or obtain access to the router through some other means to change the IP and carry on. When I connect the Belkin to my network, the router cannot see it connected to it's Ethernet port. However the Belkin's link light occasionally flickers.
