I dumped the MJ and found my password (20 characters, all caps) and loaded all the configuration information into a SPA-2102. I played around with that for weeks and didn't get anywhere, so I found a RTP300 and have been trying to set it up, thinking that it might just be trouble with the SPA. No joy there either.
I've read that port forwarding in the upstream router is required, but that doesn't make any sense to me because the dongle works fine without any port forwarding. I'm having a little trouble configuring my router to forward those ports and I don't want to beat my head against the wall for too long if it's not needed.
Any constructive suggestions appreciated.
