Flakey Ping loss, Web-Pages load fast or not at all.

[mclarty]

Hello all, I need help. Losing. My. Mind.

Web pages either load lightning fast, or they never load at all. The issue occurs, regardless of browser, OS, or computer/client. (See below for more details on network set-up).

I'm getting only ~90% of ping responses (inside of 10 seconds). But, not all the time. See attached.

I think I've ruled out DNS issues, by switching from my ISP's (Rogers) DNS to OpenDNS.

My ISP has sent a tech out, they say it's on my side.

Router/Modem:

Cisco DPC3825 DOCSIS 3.0 Gateway (Modem/Router combo), wifi enabled -WEP 64, DHCP. I had to change the IP address on it to 192.168.0.2 to get it to work. My switch likes to default to 192.168.0.1.

2nd Router/Switch.

Cisco E2000, with wireless disabled, (I believe) acting only as a switch only. I've disabled the DHCP server on it, disabled NAT, enabled Dynamic Routing.

I have Netmonitor installed on one computer, and wireshark on another....but I don't really know what I'm doing/looking at - need help to use these tools effectively. Maybe give me pointers/tips/filters to use? Maybe a way to look for relevant errors(?)

I can stream local HD movie files, without problem. Online video chat, works acceptably well. Sharing files works flawlessly between computers. It's just web-pages are SO flakey - it's like they have a mind of their own. They won't load for 5 minutes, then all of sudden, I'll give up, then that page will load 5 minutes later.

Thanks to all who read this. Any pointers? Tips? Links?
