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

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?

Typically you only want one

Typically you only want one overload statement on the router. Another thing I would remove ip route 0.0.0.0 0.0.0.0 FastEthernet4. I know it sounds silly but when you set that interface to DHCP it creates a default route itself (not visible in config). I have experienced many strange issues similar to this one where routing will work and then stop working and other strange issues.

I removed the ip router 0 0

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?

HelloAs you have RPF enabled

Hello

As you have RPF enabled I would NOT remove the default route  as I am on the understanding RPF  running I loose mode uses the default route -

 

Can you try-

1) remove the acl 100 from  RPF

2) change the default route to

ip route 0.0.0.0 0.0.0.0 Dhcp

 

Lastly is this router connecting to a fw and if so does that fw have the correct licence  for multiple user connections?

Please don't forget to rate any posts that have been helpful. Thanks.

Since FA4 is set to DHCP the

Since FA4 is set to DHCP the ip route 0.0.0.0 0.0.0.0 dhcp is not needed. It will get the default route from ISP on DHCP request.
