I'm getting very high pings (2000-10000ms), and intermittent internet connection when using a wireless router (be it on LAN or WAN). When connecting a desktop directly to the cable modem, there are no issues so I think I've isolated the problem to the router. However, even after a factory reset to the router the issue still persists. It began a few days ago and was intermittent, but is now permanent. If I ping from the desktop or from the router control page itself, I get the same results (2000-10000ms). Some websites do not respond to pings at all, while some do. I also get very high pings on Google DNS (8.8.8.8).

1What if you plug wired into the wifi router? Can you isolate whether it is the router itself, or the wifi connection to the router? – Paul – 2014-07-28T00:29:36.787
1The same issues occur if I am wired to the wifi router so I think it may be the router itself. I've also tried replacing the physical cable between the router and the modem, and the router and PC. – Zach – 2014-07-28T01:06:02.583
Is the problem just with synthetic tools like ping? Or do you see issues in real world applications? Do your upload/download rates (measures with speedtest or similar) show an issue? – David Schwartz – 2014-07-28T01:36:39.647
How is the router connected to the cable modem? Via LAN ports or WAN port? If the former, have you disabled DHCP on one or the other? – Paul – 2014-07-28T01:49:15.137
The problem is not just with the tools. Some websites will not load at all, some will load very inconsistently. If I manage to get a speed test site to load, the connection speed is fine. The problem is getting one to actually load. As for the router, it is wired to the modem. – Zach – 2014-07-28T02:07:34.953
The modem is a D-Link DIR-655. I turned off a setting called "Advanced DNS" and specified Google's DNS instead and everything seems to be working correctly now. Maybe the issue was just with whatever DNS D-Link was using? – Zach – 2014-07-28T03:44:22.017
