This is where your problem is:
Feb 19 21:36:35 (none) comm[163]: Uploading HTTP Header for modLog of /var/log/svclog: POST /tivo-service/mlog.cgi HTTP/1.0^M Content-Length: 14234^M ^M
Feb 19 21:39:32 (none) comm[163]: XferRqst timeout waiting to read
So to clarify, even if you move it back directly to the router it now still does not work?

Also run though these tests and let us know what you get.
