I had a bitch at COX a while back over dropouts and signal latency and they came out and replaced the Motorola Surfboard modem with a Cisco DPC3010 … that just about halved the latency and virtually eliminated the service drops that I was having at work. But the number one cause of large latencies is traffic - if you have a lot of traffic in the pipe (in or out) then the packet latency is going to rise. I’d measure the traffic in the pipe and see if there’s not some other source of traffic on the connection. I’ve recently moved to using both COX and AT&T in an effort to improve connection reliability and it’s working very nicely to date - I feed the two WAN connections into the firewall and the LAN uses them both giving me almost 12Mbs at home with a pair of 6Mb connections from COX and AT&T DSL.

Also take a look at your router. When my old router went flaky (which I eventually figured out), http was slow while email worked fine. Eventually, web browsers could never get the full page. Pulling the plug on the router, waiting 15 seconds, and then reinserting the plug solved it -- but two weeks later, same problem. Then 2 days, then 2 hours...

My ping times to quakelive servers got higher than usual but not by much. Cox techs, at least the ones who came out to my place, were mostly incompetent. In all their tests, the "signals" were good but my modem would disconnect every few hours or so. The modem will be back online within minutes. Won't notice that while browsing but when you on a video calls, you will. I changed my cable modem twice but that did not resolve it. I went ahead and changed the coax from the drop outside to my house to the attic distribution box and change out cable from the distribution box to the cable modem. And that fixed the issue. I don't want to move to another ISP, but if it comes down to it, i will. haha... Like you have a real choice. Unless you wan to go commercial, you only other choice is ATT and they suck too. Find out if your modem's S/N ratio is in the acceptable range and if you have the latest firmware. If you call cox tech and if you are lucky, you will get someone who will know the answer to this.

I've been running smokeping for a few weeks and every evening, about 7-11 speed and latency is very sporadic. I'm not 100% how long this has been a problem but back in april/may I started a new project where I have been working from home more and need to use a VPN to connect to another network. Actually, two different VPNs on two different networks. One, is Dell Sonicwall and the other is a Cisco. The Cisco, is surprisingly very stable and even though the network is flakey the Cisco stays connected. But the Sonicwall is very sensitive to the network outages. Any time the network glitches the Sonicwall disconnects and all my SSH connections drop. Now I RDP to a server on the network and run the SSH sessions from there. So I don't lose everything. But, this brings me back to Cox's evening service. A tech came out about a month ago and checked my signals which were all in the good range, he even replaced the cable modem on good faith. Even though the one I had was only a few months old.I replaced a much older linksys docsis2, with the Cisco docsis3 modem. So, the tech replaced my modem with mostly the same model modem, but still the signals are good. Normally, running a speed test on speedtest.net, i get around 30Mbps down, 15Mbps up. Just now, i got .75Mbps down, and 4Mbps up. My smokeping is hitting 3 Cox DNS servers and one of their web servers and a handful of other high profile servers. As well as two of my own personal, which have no traffic and should be no lag what so ever. Yet smokeping shows dropped packets and higher latency. I've called a few more times to try to explain the problem again. Monday i called and the guy said they will send someone to check from the house out. Last night I called and the person wanted to schedule a tech to come to the house again. I asked for level 2 support and was put on hold for an hour. I eventually hung up. If I were just web surfing, i would probably have never noticed and probably wouldn't care, but now that i'm using the VPN a lot it would be nice to have stable service in the evenings. has anyone else run into this and have any suggestions about how I can get to the bottom of it with cox? I don't want to move to another ISP, but if it comes down to it, i will. thoughts? suggestions? bullshit remarks from jarred? -- Have Mercy & Say Yeah _______________________________________________ General mailing list General@brlug.net http://brlug.net/mailman/listinfo/general_brlug.net
