About two hours ago my internet connection became extremely slow across multiple devices. Using the command prompt to ping google resulted in 50% packet loss in most attempts, and at least one packet was lost in each attempt. Power cycling the router and the affected devices did not make a difference.

Results of a trace to google:
Tracing route to www.google.com [216.58.218.164]
over a maximum of 30 hops:

1 4 ms 3 ms 2 ms homeportal [192.168.1.254]
2 29 ms 24 ms 28 ms 99-136-88-3.lightspeed.ftwotx.sbcglobal.net [99.
136.88.3]

Tracert is kinda stupid tool because it does not send a real lot of data.

Open 3 cmd windows. Run constant ping to 192.168.1.254 (your router) 99.136.88.3 (your isp first router) and the 216.58.218.164 ip.

If your trace is not telling lies you should see only packet loss to the final destination. This means you router has no problems and the cable between your house and the ISP has no problems.

Issues within the ISP network unfortunately you can't really do much about. The first level techs you call are really good(well sometimes) at testing the connection to your house. They likely though do not have access to the other routers in their network. You will have to work to get a level 2 or level 3 guy.

The bad thing about the trace is there is a device in hop 3 that is programmed to not respond. There is no way to tell if their is a problem between hop 2 and hop 3 or not. There definitely is a issue either in hop4 itself or between hop 3 and hop 4

Seems to be working fine today. From discussions with friends in the area who have the same ISP, it was definitely an ISP issue. I'm waiting to see if the same issues begin to happen today during the late afternoon and evening.

Thanks for your time and your knowledge.
