[Solved] Internet connection sluggish and choppy but not slow.

Hi,


Update: I am now convinced it's my ISP which causes the problems below since they are still present when I hook up to the cable modem directly, so the post below doesn't really belong in this forum, sorry.

I have a problem with either my router, an RT-N66U or my ISP which is Suddenlink. Yesterday I started having issues connecting to our corporate VPN and e-mail clients and other Internet connected applications timed out a long time before they did anything. Online gaming also got impossible being cut off all the time. When I wanted to do a speedtest it took a long time to get the Speedtest.net site loaded, but when it ran the ping and speed was very good and what it normally is when everything works. I have never seen anything like this. I also tried to do a traceroute from the router to www.cnn.com and got this:

traceroute to www.cnn.com (157.166.238.17), 30 hops max, 38 byte packets

I tried to ping from the router and got this:

PING www.cnn.com (157.166.238.17): 56 data bytes
--- www.cnn.com ping statistics ---
5 packets transmitted, 0 packets received, 100% packet loss

I am not able to determine if it is the router or my ISP. It started yesterday afternoon and is not gotten any better this morning. I am running the latest Merlin build on the router.

Any idea where I should start to look, or if calling my ISP is what needs to happen?

Disconnect the router and connect your computer directly to the modem. If it still happens then your router is not at fault.

Does your modem have a log? Could you post those logs? Could you also post the router's log as well?

try pinging / tracert to your DNS servers

I tried to connect directly to the modem and I had the same problem. I wrote Suddenlink and they came back after a couple of hours (impressive!) letting me know they had been resetting my modem three times and that it now should be better which it actually is. I still do not have any idea what was wrong. Never had that kind of connection problem before.

Thank you guys for help!
