Wrong Subnet mask Entered

I just got the 6600 back from service and I noticed it was set to DHCP. I went ahead and set it to the static IP address I had reserved for the radio. Unfortunately I typed in the wrong subnet mask. It was supposed to be 255.255.255.0 instead I typed in 255.255.25.0. I can't get into SDR to change it. Any thoughts beside changing the subnet mask for my network?

the incorrect mask should have been rejected rather than accepted!

255.255.25.0 is a valid subnet mask. Any number between 0 and 255 (inclusive) is allowed for each spot. Usually bits are masked from top to bottom, so 25 in binary is 0b00011001 is definitely odd, but not strictly wrong.
As for getting connectivity, I would expect you to be able to assign a similar subnet (and IP within the mask) to your computer, then directly connect it to the radio. That way you don't have to reconfigure your whole network - just one machine.

Got it fixed.

I tried connecting my laptop directly to the radio and then attempted to enter the mask as 255.255.25.0 on the computer and the computer rejected the mask. Fortunately someone mentioned a factory reset which resolved the problem.
