Wow, I came here looking for answers about connectivity issue with my WBR-2310, Rev A1 firmware 1.05. I'm surprised that people at DLink don't think this is widespread issue when there are at least 6 recent threads on this (this one, others from AwShuxs, Megabite, San Antonio, TheJackal, jonesb), plus the many users who posted on those threads.
And no, returning the router is not an option as it was bought more then 6 months ago. It works fine except for the annoying can't connect issue.
Firmware 1.05 has been out for more then a month, didn't someone at DLink get 5 min of their time to test and try to duplicate the problem?
