Ok, now I have another problem...

I can only use one computer (in the third slot)
unless I switch the main cable from WAN to uplink,
but then I can only use the one computer in the fourth slot...

I can't get back to the page because to re-enable the DHCP,
it keeps saying
"Page cannot be displayed" on the computer in the
fourth slot, but I can get to it on the computer in
the third slot, but everytime I try to change something
it says it has changed, but has really stayed the same....

How do I reset my router COMPLETELY?
