Hi there,

I've been using a dir-655 as my main router for a couple of years now - and thought it was time to change to the rev B version (it seemed that my old rev A had seen it's end of life)

the heaviest traffic on my network is IPTV (multicast) So obviously I've enabled multicast (for IPv4) However it seems very unstable:

first connect would not enable and join multicast groups.

Second connect after firmware upgrade to 2.09 joined the multicast group for 3 secs - and then "unjoined"

Third connect - all of a sudden it was working 100% Then a required reboot (due to power failure) of the router shut the multicast down once again.

I have tried to mess around with the firewall settings - but it confuses me to bits AND I'm now considering just using my old router- this does seem rather dumb though - also seeing as it seems the network is running smoother with the newer router.

On the rev A router the only setting which made it all work was to enable multicast, and changing back and forth with new and old works fine - so no ISP issue or the like.

any ideas?

thanks!

Link>Welcome!

• What region are you located?

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?
• 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.
