However, once modified, the WRT54GC will not take the file. I assume that there can be some addtional checksum byte hidden in the file. @rbo83:

I am logging in to router then going to admin then the sub tab "management" then clicking on backup settings. The file is saved on my machine and then in my hex editor i changed the following listed above and saved. I then clicked on the select the modified file and try to restore but it fails. Do you have any other advise. I appreciate what you have so far. Rbo,

Make a copy of it because you are going to change it. If you are on linux or windows, use a hex editor and look at the 4 characters at address 01F64 (8036 decimal) in the file. That is the HEX DNS currently set for the router (check it by converting your existing DNS to hex) Now, convert your new desired DNS to HEX (e.g. 64.71.255.198 would be 4047FFC6). Replace the old DNS at address 01F64 with this new hex number in the hex editor. Then on the router menu, tell it to reload the settings from the updated file. And you're off to the races.

Visit the router's configuration page (http://speedstream/ or http://192.168.254.254/) in a new browser window. I get nothing like a system summary, and I can't find a system summary for speedstream anywhere on the siemens site re: the instructions for speedstream http://www.opendns.com/start/speedstream_5200.php, i don’t know if am just stupid, but when I go to the link in step 1:

If it is getting a dynamic IP address setting the DNS servers does not have an effect. If I set a static IP address, the OpenDNS servers appear.

I have a friend who has multiple computers that would like to use it, but doesn't want to go through the hassle of setting OpenDNS on each computer.
