Yes, I realize that my D-Link Wireless-G WBR-1310 Version D with (the latest) Revision 4.13 firmware has reached EOL (End Of Life) in 2012.
However, at the end of the day 12/31/2012, the date did not "roll-over" into '2013'.
Instead, the router time-warped into '2002'. Huh?
When I tried to manually set the year, the only only choices are '2002' to '2012'.
If I choose '2012', and then "save settings", and revisit the pull-down,
the values still show '2002' to '2012', not '2012' to '2022' (which is what some routers do).
When I tried "copy my computer's date/time", the month and year and hour and minute and second were updated, but the year was set to '2002'.
When I tried connecting various NTP-servers, the router did not update to '2013'.
The problem is that the router's DHCP-server will not generate valid DHCP-leases, because the date/time that my computer sends to the DHCP-server, plus the TTL (time-to-live) for the lease, means that the generated lease has already EXPIRED, and thus will not be sent to my computer.
So, no Internet access, without getting a valid IP-address.
Similarly, since the date/time in the router are wrong, my ISP's DHCP-server won't grant an IP-address for the 'WAN' interface on the router.
Any sugggestions, other than buying a different router?
From limited online reading, I get the impression that the DD-WRT firmware requires more RAM than is present in this router. Sigh!
