router - What could be the causes of DNS Client Event error in windows log?

    Long story short(and most likely the cause). Recently had work done on my cable in front of my house, and they screwed it up several times. for about a week, looked like i could stop complaining to them.

    All of a sudden I'm getting internet disconnects all the time and random. No rhyme or reason, although a lot happen between 8pm and 11pm.

    I noticed in my windows log when ever one occurs, i get a DNS Client Event error.

    I'm fighting the cable company to replace it properly, they keep patching it. The only thing i really changed on my computer was a video driver update, not sure if this could cause the issue.

    Why i wait for this awful company to replace my cable, what else could i check? Could it be a virus or maybe my cell phone connected to the wifi, is comcast throttling me(not doing anything besides a few online games)? Could it be some type of interference from a neighbor? I did try to go into the router and change the primary DNS to 8.8.8.8, but the issue still occured later that night.

    I've checked all the connections inside and outside. And also my TV experiences issues with sound and video pixelation, usually have to change the channel for it to correct itself.

    Edit: Also, some of the time, the cable modem(i have a separate wireless router) would show a disconnection, the connection lights would go out and have to reset itself.

    So this is a problem I've had pretty consistently since I got my cable broadband hookup, and its starting to get on my nerves.

    When I'm just doing regular browsing or playing a game, its fine. But when I start streaming movies and video or downloading via bittorent, it'll sometimes just disconnect. Usually unplugging the router and plugging it back in will fix it, but sometimes I have to unplug the cable modem too. And sometimes I have to unplug both of them twice to get my internet back.

    I use a personally-owned Motorola cable modem that I bought a few days before the cable guy came so I don't think that its broken, and I have a Linksys E2000 router, which is one of their better consumer models. So I don't really know what the problem is here. I want to call the cable company and get someone out here, but I want to be sure its not a problem with my own hardware.

    My router links my PS3 and my computer with a wired connection, and my phone wirelessly.

    If you have connection issues, simplify things or you'll never figure out what is going on.
    If you direct connect to your modem and stream, do you still get disconnected? Routers fail fairly frequently. Even if you paid $600 for your enterprise grade router yesterday, it can still fail today, it happens, never rule it out as a possibility just because you don't think it should have failed.
    Have you tried swapping out cables? Bad cables are a very common cause of poor or intermittent connections. This includes ALL cables, including those in your walls. Sync up at the cable junction box with a laptop if you need to.
    Have you checked to see if your cable company is having issues with their CMTS? This is not as likely, but can be a possibility if you've ruled out layer 1 issues on your side.

    Have you made sure to update the firmware on each device to the latest version? I had a similar issue with my linksys router and updating the firmware helped a lot.
