Hi, I have a DIR-868L router.  I have Tivo Roamio Pro that today, out of the blue, started giving me an error message saying that it cannot connect to the internet, and an error message that says "No DHCP Server."  All of my computers, etc., connect to the internet fine.  I can still watch live tv through my Tivo, but I cannot use any of the internet apps on it (netflix, amazon, etc.) -- also, now none of my Tivo Minis can connect to my Tivo Roamio, so I effectively can't use any of my other TVs.

I tried restarting the Tivo box, restarting my router and cable modem, no success.  I called Tivo support, and they suggested that one problem could be that the Tivo service requires certain ports to be "open" on my router, and certain ports to be "unrestricted" on my network.  They explained that it was possible my router received an update which could have closed up some of the ports that need to be opened.  They gave me a list of 9 ports that must be "open" and a list of a few dozen ports that must be "unrestricted" -- there is some overlap between the two lists.  My problem is, once I log in to my router, I can't figure out how to ensure that the required ports are open, and the other list of ports are "unrestricted."

At least with respect to the first question, I believe that to make sure the required ports are open I go to the "Port Forwarding" page when I log in to my router.  The problem when I do that is that it asks for the IP address, and when I check the IP address on the Tivo, it's giving me a 169 address, which I gather is a problem.  When I try to put that 169 IP address in the IP Address field on the Port Forwarding page, I get an error message saying "Invalid host IP address." 

Any help would be appreciated!  Thanks in advance.

Link>Welcome!

• What Hardware version is your router? Look at sticker under the router case.
• Link>What Firmware version is currently loaded? Found on the routers web page under status.
• 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?
• Is ISP Modem/Service using Dynamic or Static WAN IP addressing?
• What ISP Modem service link speeds UP and Down do you have? Link> Speed Testing Sites
• By-pass the main host router and check internet connection by connecting a wired LAN PC directly to the ISP modem to verify connection access and ISP speeds.
• Check cable between Modem and Router, swap out to be sure. Link> Cat6 is recommended.
• Check ISP MTU requirements, Cable is usually 1500, DSL is around 1492 down to 1472. Call the ISP and ask. Link>Checking MTU Values

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. Besure to log into the Admin account on the router.

• Turn off TrueGigaBit Routing under Setup/Internet/Manual for those routers that have this feature for testing.
• Turn off ALL QoS or Disable Traffic Shaping (DIR only) GameFuel (DGL only and if ON.) options, Advanced/QoS or Gamefuel. For the DGL-5500, review this for Streamboost information and settings: Furry's DGL-5500 Review
• 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 or Disable Use Unicasting (compatibility for some ISP DHCP Servers) and test under Setup/Internet/Manual. Disable may help with speed performance on higher speed ISP services.
• Turn on or off DNS Relay under Setup/Networking. Link>Finding Faster DNS Addresses using Name Bench and input new DNS addresses under Setup/Internet/Manual.
• 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 and maintain consistency for applications that need to connect as well as mapped drives.
• Ensure devices are set to auto obtain an IP address.
• If IPv6 is an option on the router, select Local Connection Only 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. The DST setting is only needed in the NA region. Tools/Time.

You may want to set up some QoS rules using the Global example seen here:
