Thread: Random uncommon lag spike

Hello all,

This problem has been going on for almost two years now. I have called for services for a few times and they came over and found nothing wrong.

Problem:

Once in a while - it could be once a day or twice a day or maybe even once per week. It's really random and uncommon/rarish. My connection just freeze for anywhere from 5 to 10 seconds. No activity at all. So if I was on online game, my game would lag, I can't go anywhere on web browser at all. Ping would just time out. All during the 5-10 sec lag spike.

I have tried new routers and even my Linux box with two network cards doing the routing - still same problem. Most of the time, the internet is stable and fast. But just this 5-10 sec lag spike that would jump out of nowhere after a long day/hours of stable connection.

After it lag, I went straight to 192.168.100.1 and see this message "DHCP warning - non critical field invalid in response" and the time matches the same time of lag spike, every single time. People would say it's normal message but why does it say that message at every single time I get a lag spike?

I have tried new cable modem too. TW just want to keep sending me technicians who will tell me my line looks ok, etc etc etc and nothing will be fixed. I do have another tech coming by again tommorrow though (for probably the fifth time).

Random delays like this are hard to track down.

It could be anything from an overloaded Node, a Node rebooting, Your Coax cable being affected by malformation(someone stepping on it, door closing on it, car driving over it, water in cable, faulty cable joint affected by something moving it) to Electronic Interference from Mobile phones, Ham/CB Radios, badly grounded equipment etc.
