Looks like I spoke to quickly. Seems as soon as the disks stopped spinning (went into hibernation), all PCs lost connections and do not connect. PS3 still connects.
Everything is back like it was except that eventually I started getting 2 pink lights. Is it possible my drives are going bad? I restarted it and now its back to normal blue lights, I'm still able to connect through FTP though.
I tried the nbtstat command and it only worked on my local PC and the DNS. The local PC returned the MSBROWSE keyword. I did not get a response from the router or my iPhone or PS3. Actually it says "Host not found" and I'm not really sure how to interpret the information from that command. Man, this is really frustrating trying to consitantly connect to the DNS.
I've turned off the firewall, turned on Network discovery, turned on file sharing and don't know what else could be blocking it. I love my router but I'm wondering if that is the problem.
Thanks for the help everyone.
