4480, were you able to resolve your issue?
I'm sitting down with a roborio and the router finally, and I'm having a similar issue. I did reflash the router, and I can confirm that it's definitely a DNS issue (at least, on my mac it is):
Examining the tcpdump output, it looks like this is happening:
- t=0, query to multicast 5353
- t=0.1 response from roborio on IPv6
- t=0.2 cache flush AAAA from roborio?
- OSX sends 6 ICMP6 neighbor solicitations trying to find IPv6 address of roborio, no responses
- t=6 first ssh syn packet to roborio from computer (ipv4)
Here's the raw tcpdump output for those interested:

Interestingly enough, I found a workaround. If I connect to roborio-2423-frc.lan, that works almost instantly. Of course, it would only work when connected to the router, and I suspect the router will be configured differently at competition...
