Hi. I'm glad I found this place cause I'm almost ready to give up on this problem. Maybe you can help me.

I have been getting random disconnections since November, and several Comcast technicians have come over to my house to see what my problem is but they can't find the source of the problem. They have checked my wiring and they SAY everything is fine. I have bypassed the router and the problem is still there.
My PC and my laptop have the same problem, so I figured the problem was the signal and not something in the computers. But because I have tried making Comcast do something about it without much success, I guess maybe there's something wrong with my computer.

I have RAN Adaware and AVG antivirus.. and they don't really find something wrong. Then I checked these forums and found similar posts in which the OP wheres asked to post a Hijack this log. I don't know if this is the right place to post these logs, so forgive me and redirect me to right place. But here it is:

(hoping there's something wrong that can be fixed haha)

Thank you in advance.The log is clean.
What do you mean by disconnection? Modem/router lights go off, or....?Well my modem can look fine and still be DISCONNECTING. Sometimes I noticed the cable light blinking on the modem. The last technician I contacted told me theres probably something wrong with the line that comes from the pole to the back of my house. They have been working on the poles outside my house but the problem is still there. I guess they will have to come back again to check the lines.
The problem usually happens in the evenings, with random disconnections that last a few seconds, then as it gets later in the night it worsens and the disconnection lasts several minutes; when it connects again it only gives me a space of a few seconds to load pages, etc. It is really weird, cause it doesn't happen every night. I thought the cold weather on some nights might be affecting it, but they tell me it shouldn't be an issue.
I just wish they could find something wrong with the lines, or something to give me hope that it can get solved.
Thanks for your answer to my post and your help.OK. Am I right, that by disconnecting, you mean, you can't open any web site?
If so, what browser, version?
Did you try another browser?
Did you double check, it's really connection problem, by running ping command, when the situation happens?By disconnecting I mean the connection is interrupted, lost, unable to communicate with the web. When it happens I can't browse, download, stream or play online because there is no connectivity. We FIRST noticed it because some pages wouldn't load and we had to click refresh until they did. We thought maybe it was the website being slow with traffic, but then my brother who plays World of Warcraft started noticing that he would disconnect randomly. He would start lagging a little and then suddenly he got disconnected. He had to keep on logging in the game. He always ask the people in the game if the server is lagging, and most of the time it's just our connection being unreliable. Neither my PC connected directly through a cable nor my laptop (wireless) can connect to the Internet when the problem happens.

The problem is very random, I tried to notice a pattern and I still don't get when it exactly happens, aside from when it happens it gets worse at night time. For example, today it's not causing any problems apparently, but I'm sure this doesn't prove it will also work tomorrow.
The technicians over the phone have noticed that the connection drops because I call them when it's not working, but when they send the technician most of the time they don't find anything wrong because as I said, one day it can be bad and the next one fine. I really hope they come check their lines or something, cause when they come to my house they don't find anything wrong, and I am honestly tired and frustrated of having technician appointments almost every week for the past two months without getting good results.
The other thing that discourages me is that about two weeks ago there was an outage in my area, and supposedly that was what it was causing the problem. They fixed the outage and my problem still persists. Basically, it's very weird, and that's why I need to make sure that I check any possible thing that can cause this.
I hope I don't sound like I'm complaining too much, I really appreciate your attention to my problem. Did you ask ISP to replace the modem?
Is any router involved?They did replace the modem, and as I said I bypassed the router and the problem was still there.

Thanks though, because it seems in the past days I haven't had any noticeable lag issues. Hopefully the problem is solved and it will continue like that.Let's hope, it stays that way
