Here we go again internet went down again! Woke up this morning at 6 am without internet. Its a daily routine for me now to reboot modem and router every morning! I hope Cox is following this issue. Here's the log from the new modem: https://photos.app.goo.gl/jK3m3PhcXNbLQPr4A https://photos.app.goo.gl/FkoSE2g7gjvwyqCH9 Here's the picture of modem and router LED lights: https://photos.app.goo.gl/Qm2D1jJ6HfQ3B4xj6 https://photos.app.goo.gl/Yt2974LzmmSmrBoTA photos.app.goo.gl/uNMC5WrM8sesCMmBA153Views0likes1CommentRe: Frequent Internet Dropping
I didn't really get a chance to tell him about the logs because I was at work. I was just able to tell him the general issue and how long has been going on. I assumed that he was going to check all that you know, since they he is the expert. For the other question, If I can remember right, I cant access the modem web page when connection goes down. And when I reboot and reconnect to the internet I didn't see any entry in the log that could say when or how the internet went out. It just shows the time when I reboot the modem and when it reconnects to the internet. If it goes down again, considering that I have replaced the modem and connected a new RJ45 then Im going to try to move my modem location and use a different ethernet cable. if this still doesn't work then I down know anymore. I wish we have other ISPs in my area but, Cox is the only one we got :(25Views0likes1CommentRe: Frequent Internet Dropping
Just an update, the tech guy (tier 2 tech) came yesterday, I wasn't home but my wife was and I was communicating with him over the phone and told him what has been happening. Hefound something was wrong with the ethernet cable that connects my modem to the router. One end of the cable RJ45 was loosing contact with the wire. When he tried to move the cable from the back of the modem the connection between modem and router would cut off indicated by the amber/red LED light on the router. I used an ethernet cable tester and it confirmed that it was indeed the RJ45 had lost contact with the wire.So I then replaced the RJ45 and still using the same ethernet cable. Used the ethernet tester again and it showed there was good continuity in all wires. Thinking that this was causing my connection problem, I told myself I dont need this new modem so I put the old modem back and called Cox to have it setup again and everything was working fine. Then this morning, again the internet went down! I am back to the same issue. Modem and router showed no LED light errors. I checked modem logs and showed that channel 9 still has high uncorrectables and my SNR is running at 34db at the lowest. I put the new modem back and I will have to see if this continues to happen.133Views0likes3Comments- 204Views0likes3Comments
Re: Frequent Internet Dropping
This is what my downstream and upstream look like now after bypassing splitters and router. Right now the connection is just the cable in to modem thento pc. I did this 12 hours ago and have not lost internet connection, however there are times that it was really slow. Here's the link to down/upstream: https://photos.app.goo.gl/5mQogvXFtk3Vc4Kw7 Still channel 9 correctable and uncorrectable code words is off the charts!19Views0likes1Comment
