In response to your questions in the other thread (sorry for not responding to that one; I must have forgot to press "notify" on that thread:
What region are you located?U.S.
What ISP Service do you have? Cable or DSL?DSL (U-Verse)
What ISP Modem do you have? Stand Alone or built in router?
What ISP Modem make and model do you have?It's a Motorola 2210-02. It's set up on bridge mode so that the router gets a real WAN IP.
Some things to try: - Log into the routers web page at 192.168.0.1.
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.All turned off.
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.Check.
Set Firewall settings to Endpoint Independent for TCP and UDP under Advanced/Firewall.I've got UDP on Address Restricted, and TCP on Port and Address restricted. Unless there's some real connection between the firewall and UPnP though, I'd rather leave these as they are since I can't reproduce the problem quickly and would have to leave them less restricted for a long time.
Enable uPnP and Multi-cast Streaming under Advanced/Networking. Disable uPnP for testing Port Forwarding rules.There WERE both enabled, though I just disabled IPv6 multicast streaming to see if it would fix that log thing (it didn't, see below).
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 SpeedIt's set on Auto, and as far as I know, my modem doesn't support Gigabit.
Turn off all anti virus and firewall programs on PC while testing. 3rd party firewalls are not generally needed when using routers as they are effective on blocking malicious inbound traffic.
Turn off all devices accept for one wired PC while testing. Where applicable these are turned off; usually when the UPnP failure occurs, there is only one wired PC connected to the router turned on. I don't usually notice til I try using the other devices though.
Check cable between Modem and Router, swap out to be sure. Link> Cat6 is recommended.The cable is still there
On an additional note, it seems like about every 4-5 seconds, I get the following messages in the router's log (addresses redacted):
Jan 14 11:16:14 info version 1.7 started
Jan 14 11:16:14 info Joining mDNS multicast group on interface br0.IPv6 with address <IP6address>.
Jan 14 11:16:14 info Leaving mDNS multicast group on interface br0.IPv6 with address fe80::218:e7ff:feef:f5b8.
Jan 14 11:16:12 info Joining mDNS multicast group on interface br0.IPv6 with address fe80::218:e7ff:feef:f5b8.
Jan 14 11:16:12 info Leaving mDNS multicast group on interface br0.IPv6 with address <IP6address>.
Jan 14 11:16:12 info version 1.7 started
The log's just completely full of these messages since they pop up so often. It's making looking for any other log messages hard, but also has me concerned there's something else up with all the constant leaving and joining.
Edit: I'm going to turn IPv6 to local-only for the time being since that seems to get rid of all these extra log messages, and might help make debugging the UPnP thing easier.
