I'm having strange random connection failures. Are there ineffieciency in my config?

Question

I've been having strange, random connection failures and I'm trying to eliminate possible causes.
What happens is while I'm browsing on the net over wifi, a link will at random not connect to the site, but instead fault to the ISP error page. It happens with highly reliable sites like google, or ebay, or whatever. If I direct connect to the cable modem, the problem site is immediately available.
I'm sitting <6 feet from a 871W router (with antenna). There's one router in my building and others are at my neighbors. 
Below is the conf file. Just to imagine how rediculious this problem is, here's a screen shot from a web page. This shows a web page I visited, and after clicking on a link (an embedded youtube video), the error showed up within the page itself.
Why would only some URLs fail to connect? Is there inefficiencies in my config?

Answer 1

I removed the ip router 0 0 to no great effect, which I consider to be a win.
I'm guessing that since overload is what--I understand--translates the one outside to the many inside IPs, that the suggestion to have only one overload configured means I should combine the two ip ranges into one.
I deleted 10.0.0.0 network. Changed the bridge references to 1 and vlan references to 1. Now wifi and ethernet should all be using the same internal network? That's the idea, right? Any more fat?
