Got a question for cable internet connection pros

[tony286]

Ok, I have comcast.
About a month ago my internet would go out. I would turn off the router and the modem. Then pull them right back in and they would reboot and then it would work. It started happening more often. I replaced the modem and it still happened. Comcast came out of course it being so intermittent he found nothing. The signal was fine he said. It happen that same afternoon again. I now got replace the router(it was 4 yrs old). Today its happened again twice. Any ideas? thx

Does this happen on all devices? Computers, tablets, phones? What about TV cable connection, fine?

cable tv is fine. It happens to all devices, the wifi devices and the hard connected one (my desktop)

We get that often, too - drops the signal to all devices (laptop, tablet, cell). I just unplug the Cisco wif-fi router...let it sit a minute, then replug it in.

It happens maybe once a week (or so) - not really a big issue so I haven't looked into replacing the router yet.

Ask your neighbors if they have similar problems. Anything that you can do to narrow down where the source may be could help.

Didnt think about that, good idea. thx

[mikesouth]

another thing you can do is power down yer devices one at a time and then bring it back up and see if it fixes the problem..that should isolate which device has the issues


My moms was doing that and it was the router

if it looks like comcast is the problem they can monitor your connection (prolly already do)

may not hurt to try a ping and a traceroute as well

I lived in a older apartment a few yrs back, old coax was wired in the 1980's and had the same issue, would drop multiple times a day. Cable co said everything was fine . This solved it for me:

Could it be something simple like a broken cable or dirt in the connection? When I had this problem about a year ago, Videotron came around and swapped the cable that connected my house to the pole and this solved the problem.

Your cable company may also be able to see the connection drop. They can see your IP address and when your model is on and connected (which presumably is all the time). If you lose your connection, call them right away and find out what they can see on their end.

Routers get shitty as they get older, heat takes a toll on them. It probably has never had a firmware upgrade on it..which is always a good idea to stay on top of. This is especially true when it comes to the wireless signal is putting out. If you have a new router, make sure its got the latest firmware upgrade as well. Also make sure you that you have one of the latest cable modems with whatever they are providing in your area..DOCSIS 3.0 / DOCSIS 3.1 and make sure the cable modem has its firmware upgrades as well....which is a good reason to own your own instead of leasing one, because cable companies are for shit about keeping their leased modems up to date...

You should also check on what band and channel you are broadcasting on....b/g/n and auto & 1-11 ex. You can download a free wif analyzier for google play or itunes that will show you how many devices you have broadcasting and on what channels. Moving your internet wifi to its own clear channel will help. House phones and other electronic devices operating in the same channel can impact your inwifi if you are having issues with that dropping in and out as well

On the cable company end, it could just be the cable just going in and out and when that happens, of course the modem will grab the new DHCP address before your router...in a perfect world the router should grab the new IP address and then pass it down to the PC....that doesn't always happen. Which is why you have to do power down and up cycles with the modem, router, and PC.

If its happening with a new router, that means its either:

a) Cable modem failing
b) Cable signal dropping from your box to the modem
c) Coax is old and getting shitty...
d) all of the above

It would be a good idea to have replaced all the coax from the main splitter in the house to the cable modem, unless its a dedicated line (which they usually are) and replace your Cat5 cables that run between the modem and routers...believe it or not..those can get shitty over time as well...

Im sorry i wasnt clear. I have replaced the modem and the router. They are both less than a week old. When the comcast man came out I had just replaced the modem. He checked the signal and it was fine.Then it went out again. So then I went out to replace the router. I had no problems until about a month ago before that it was perfect . I think what I will do is the next time it goes out is instead of turning everything on and off to get it to start back up. I will call comcast.

I am not the techie type, but we had this happening for a long time here too on Mediacom - we kept replacing, rebooting and everything - bought all new gear and everything same as you.

FINALLY we had a good tech come out, he had recently moved down here form a big city and wasn't an uneducated fool like our current people were... what happened he said was trash in the lines, and yes he dumbed it down for me. lol

There was 1) Trash in the lines, the waterproof seals they had put on them had basically sprung a leak and water and dust particles and other things had gotten in there between the connections and was trashing up the lines.

Next they had to replace their lines that came to our house, they were so old they were beginning to fray, so he replaced that line and everything worked perfect.

All the previous guys could ever do was just tell us it was on our gear, which I knew better because it was all new, but this guy went right to the problem and had it fixed within an hour.

Tell him to go to the connections OUTSIDE your house if nothing else works and see if that will help.

Same thing happened to me. When the tech took apart the outside connections water came out of them. No problems since he replaced the line from the pole to my house.

And they'll tell you to turn it off and back on

You should really call them EVERY time this happens. Let them know how much of a disruption this is. Without calling them and reporting this EVERY time they'll just let their shitty system stay shitty.

I know what you mean, I did the exact same thing - But since doing that, now I know it wasn't my gear so I have great backups in case it ever IS my gear. lol

But they aren't ever going to just openly say it's their work - that would be suicide. lmao

I now just ask for that service guy when I call and won't even let any of the others in here. lol
