network woes

I am having weird network problems this morning. After rebooting, I still am. Some connections work, sometimes. Others not. I can occasionally get a webpage to load for me. I got this one to. We'll see if it loads the post or not. I can't get to my mail. My weather program shows a temp in the task bar, but when I try to open it to get details it doesn't load.

I'm wondering if the router is going belly-up again, but in some slow intermittent annoying way.
