check the stickers on your router... like with motherboard in computers,
there are different revisions... if your router is a version 1, then i'd
use that firmware... if your router is a version 2, then that...

correct...

what was the firmware that was on it before you updated it last time? but
really, though, i think it has to do with the version of the router as to
which version of the firmware you can put on it...

not a problem... i've seen similar before... that's why i said to look at
the stickers and see if you can find the router's version... it made a
difference, in my case, of whether or not i had a router or a brick ;)
