Ok man. Just checkin on ya. Seems like we might have helped the router work a bit better. Let it run as is. I wouldn't upgrade FW. Should work well. Keep us posted when you can.

Enjoy.

Uptime now almost 8 days. Small problem however...I can no longer get to the admin gui at 192.168.0.1
I have been able to access fine, and have just let it run for days now. Had to do a kernel update and after
I closed the page and rebooted my Ubuntu machine, I could no longer access the page. My XP box is also unable to get there. Any ideas on what to do?

I sure hate to do a hard reset now that everything is working fine.

Shouldn't have to do a hard reset, however you could just power OFF for 15 seconds and back on. Odd that the UI is not accessible though.

Update: After watching and waiting, I finally believe that the issue may be diagnosed correctly. Over the past month or so, I have had these random disconnects. Originally, because I had installed the new D-Link router I thought the issue was something to do with it. However, after watching everything, and especially the past 2 weeks when the disconnects got worse and worse, I saw my modem reset itself. I called Cox Internet and they sent the techs out. Three service trucks and a van showed up and they found some serious line interference on the run that feed my house and others. They will begin testing and fixing the line noise. I belive that once that is done, the d-link will be fine, without a firmware upgrade.

Fuzzy: I will keep you posted. I can say there is value in watching, waiting and observing rather than just running out and changing something.

Well hello again! I was hoping not to have to post here but I thought I would give
an update on my situation, especially since the folks here on the forum have been so helpful.

I have no clue as to whether or not Cox has actually fixed the line, however my modem is no longer resetting itself.

I have gone ahead and done a firmware upgrade to v3.13 and that seems to have fixed the issue of my all my connections dropping off and also some of the router lockups and me having to yank the plug on it. Not sure if that issue is actually solved but will continue to monitor it. I am very hopeful that it is.

As for my random disconnects goes...they still have persisted. They mostly show up when I play a MUD game, which of course is basically a fancy telnet session. I use mudlet which is a fine client. After careful watching and waiting, I finally discovered that it seems to disconnect every 10 minutes if I am in a situation where no data passes the connection. I searched around in the manual and found this:

Under Firewall Settings:
NAT Endpoint Filtering - Endpoint Independent - Any incoming traffic sent to an open port will be forwarded to the application that opened the port. The port will close if idle for 5 minutes.

I have tested this extensively over the past week and can confirm that idle ports are closed after 10 min. By idle I mean no data passes over the session in either direction.

Is there any way to turn this feature off? I don't want it to close any session unless I close it.  I have searched the manual but see no way to stop this unwanted action.

I presume that if there is no data flow in either direction, that any router might close the connection due to inactivity and would keep the connection open if there as some sporadic data flow with in the 5-10 minute time frame to reset this time out. Does your faux telnet program have any sort of "Keep Alive" connection option?

This is the first router I have had that does that. I did set an idle out timer on my mud client and that is how I can confirm it closes the session at 10 min.

I was wondering if session limits are in effect if I choose the Address Restricted option?

Possible...i would test each of the settings out.

I would check the following as well:
Turn off ALL QoS or Disable Traffic Shaping (DIR only) GameFuel (DGL only and if ON.) options. Advanced/QoS or Gamefuel.
Turn off Advanced DNS Services if you have this option under Setup/Internet/Manual or under Setup/PARENTAL CONTROL/Set to>None: Static IP or Obtain Automatically From ISP.
Enable Use Unicasting (compatibility for some ISP DHCP Servers) under Setup/Internet/Manual.
Turn on DNS Relay under Setup/Networking.
Setup DHCP reserved IP addresses for all devices ON the router. Setup/Networking. This ensures each devices gets its own IP address when turned on and connected, eliminates IP address conflicts and helps in troubleshooting.
Ensure devices are set to auto obtain an IP address.
If IPv6 is an option on the router, select Local Connection Only or Disable IPv6 options under Setup/IPv6.
Set Firewall settings to Endpoint Independent for TCP and UDP under Advanced/Firewall.
Enable uPnP and Multi-cast Streaming under Advanced/Networking. Disable uPnP for testing Port Forwarding rules. Disable IPv6 Multi-cast Streaming if IPv6 is not being used.
Turn off WISH, and WPS under Advanced.
WAN Port Speed set to Auto or specific speed? Some newer ISP modems support 1000Mb so manually setting to Gb speeds can be supported by the router. Advanced/Advanced Networking/WAN Port Speed
Set current Time Zone, Date and Time. Use an NTP server feature. Tools/Time.

Well Hello Again!

I want to report that it seems all the issues that I have reported in this thread have been solved, and you can mark this thread as RESOLVED.

The issue of the router locking up, dropping all internet connections, and requiring me to pull the power plug to reset it was solved (I believe) by upgrading to the latest FW v3.13NA. This was described in the release notes as "fixed the wireless disconnect issues."

The issue of the router loosing connections when I was using my MUD client or with telnet sessions when I am logged into an internet server but idle is a router issue as detailed in the manual I referenced above. I have solved the MUD client issue by setting up an idle trigger. The telnet session disconnect issues persists.

The issue of troubleshooting these problems at the same time my cable modem was misbehaving was challenging, to say the least. I must confess that I was losing faith in the DIR-615 and had purchases a still shrinkwrapped Linksys WRT54GS2 for $15 as a replacement, however it will now be a backup. The DIR-615 performs quite well.

The only issue remaining for me is the date issue, but to be frank, I don't really care if it keeps the right date or not. All it needs to do is toss packets the way I want. I have plenty of other devices to keep time.

I would like to thank FurryNutz for helping me. I appreciate your
professional approach and patience. I don't know if your paid support or just a volunteer, but you should be congratulated for the effort you put in here! Thank you.
