Like said in the title, IRC, IMs, anything else that requires a constant connection cannot stay connected when there are P2P running (stays connected just fine without P2P). This happens quicker with SPI turned on. Without SPI, it can stay connected with more connections. Although initially I've thought it was only IRC, but through some more testing, it seems to drop the IM ones as well. It is just IM disconnection and reconnection happen with much less fanfare than IRC. The behavior of the router seems like it is drops older connections in favor of the new ones.

The only change I've made to my network is replacing the old DGL4300 with the DIR-868L. I've done much worst to the 4300 without it dropping connections. It is a little frustrating that buying a new top end home router and having it performing worse than my 8 year old one. I always tried all the basics, lower maximum connection counts, played with firewall settings etc. Prefer not having to foward/trigger ports. Any other things I should try other than throwing it out the window?

Welcome!

• Link>What Firmware version is currently loaded? Found on the routers web page under status.
• What region are you located?
• Are you wired or wireless connected to the router?
• Has a Factory Reset been performed?

Internet Service Provider and Modem Configurations

• What ISP Service do you have? Cable or DSL?
• What ISP Modem Mfr. and model # do you have?
• What ISP Modem service link speeds UP and Down do you have?
• If this modem has a built in router, it's best to bridge the modem. Having 2 routers on the same line can cause connection problems: Link>Double NAT and How NAT Works. To tell if the modem is bridged or not, look at the routers web page, Status/Device Info/Wan Section, if there is a 192.168.0.# address in the WAN IP address field, then the modem is not bridged. If the modem can't be bridged then see if the modem has a DMZ option and input the IP address the router gets from the modem and put that into the modems DMZ.
• Check ISP MTU requirements, Cable is usually 1500, DSL is around 1492 down to 1472. Call the ISP and ask. Link>Checking MTU Values
• For DSL/PPPoE connections on the router, ensure that "Always ON" option is enabled.

Router and Wired Configurations
Some things to try: - Log into the routers web page at 192.168.0.1. Use IE, Opera or FF to manage the router.

• 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. Link>Finding Faster DNS Addresses using Name Bench
• 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 or Disable SPI to test.
• Enable uPnP and Multi-cast Streaming under Advanced/Networking. Disable uPnP for testing Port Forwarding rules. Enable IPv6 Multi-cast Streaming for routers that have a Media Server option. Disable IPv6 Multi-cast Streaming if IPv6 or Media Server 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.

• Check cable between Modem and Router, swap out to be sure. Link> Cat6 is recommended.

Thanks for the reply, but I already tried the pertinent settings listed before coming on the forum. Most of the list has to do with general disconnect problem, which I don't have. My IRC can stay connected (only tested for 3-4 days) without P2P. Only when it is tracking many open connections it has problem. Many as in very few compared to my DGL4300, as only 2-300 open UDP sessions is needed to make it drop IRC connections (it'll disconnect in 20-30 seconds when there are 800+ sessions). Active connections, such as HTTP and FTP downloads, doesn't get dropped even when there are many more open sessions. First sign of problem is that IRC will stop getting ping pong events. Probably means the router closed the connection and the IRC server cannot traverse through the NAT anymore. I've tried generating a bunch of TCP sessions, and it too will make the router drop the IRC connection.

I've tried triggered ports and port forwarding. Neither helped.

PS, where is a setting in the router for admin time out? It was very annoying to enter bunch of stuff and have it time out on me before I saved.
Also, why I can't use the drop down list for computer name for IP when I use DHCP reservation?


^Edit, I got IRC to stay connected by forcing the client to use IPv6 through teredo tunneling. What a hack of a "solution." Now, if I can just get my IM to stay connected o__0

It would be helpful to us if you could post some of the results and answers to the questions back here as this would be helpful to us in gaining a better idea of what your system is and what is going on and would be beneficial to you as this would help us give better feedback and suggestions in finding a resolution to your problem. We understand the need to resolve this and do it on your own as well. It just helps if you could post information so we can help you better, not just saying that you've already tried that already. Not everyone has the same problems and in some cases like this, this is a odd ball issue that nobody else has brought to our attention here in the forums. So working with you to get as much information helps us help you find the solution for these cases. However it seems you have found a work around that works for you and thank you for sharing the solution.

We can presume that IPv4 does not work as expected for your chat program?
