Did someone accesss my router maliciously? (Score 1)

Same AudiTuner from the DLink forums. After posting a response on the DLink forums I noticed that my wireless connection suddenly cut out. This is odd because I always have great reception in the room where I lost connectivity. When I tried to reconnect, Windows' troubleshooting claimed the problem was "low signal strength". Even if this is correct, I have never had any problems with signal in this room and it seems odd that after days of up-time I would just looses my connection. I looked at the log on my router and there are a few things I'm not sure about in the beginning of the log. Specifically, how settings were saved when I was browsing the web and typing a response on their forums. The computer the the log claims made the changes (192.168.1.100 on my network) was not being used at the time and no one here except myself even knows the IP address of the router, let alone what to do in the configuration pages. I've added an entry to my journal on this site with of all activity logged on my router. Could someone more knowledgeable than myself please have a look at it to see if some malicious DLink employee accessed my router or if it just an "odd" coincidence? I'm unhappy with this company either way, but I would like to know if one of their employees thought they were being clever and illegally accessed my router.
