No proxy is used. I use Verizon FIOS with the Actiontec MI424WR router for Verizon FIOS and have for years with no problems. I have the minimum speed, 5 MB/s download, 25 MB/s upload, and get those speeds according to http://www.bandwidthplace.com/ and http://www.speedtest.net/ (just now checked to be sure).
Whoops, initiated full system background scan by accident looking for proxy settings. Then, LU failed with a 8920,208. Waiting to see if the background scan fails with a 3038,104 when it gets to that. Usually background scans just skip a step if it fails, so I'll look at the log.
Here is a log entry that may bear on the 8920,208:

Here's the log entry on the failed LU:

Whooa. Browsing the security history, I see something made a whole lot of file accesses that were refused abour 11:25 this morning. They were all attempts to access N360 files. There are a total of 64 blocked file access warnings. The first one is (hey, I discovered Copy to Clipboard!)
