Internet keeps going down

[Riekopo]

My internet goes down at random and I can't figure out why. I have an Asus RT-N66U router. Its firmware is up to date. I'm running Windows 10 Home 64 bit on my PC. I'm using Cat 6a cables. I'm using TrendNet TPL-420E2K powerline adapters. I've reset my network adapter and reset my router. My OS is up to date. I really need to get my connection stable because my fantasy football draft is soon.

This could be a lot of problems. You need to narrow down the problem to a device. Is your router over heating? Do you have a PC problem? Do your powerline adapters have an issue? If you think it is your powerline adapters try running without them for some testing. Do you still have the problem?

I have experienced similar problems. The first step is to ping the gateway. I use a batch file to do this:

set "ip="
for /f "tokens=1-2 delims=:" %%a in ('ipconfig^|find "Default"') do if not defined ip set ip=%%b

ping %ip%

The alternative is to find the LAN IP of the gateway via the DOS command line: ipconfig and ping the gateway IP.

If this is not successful, then you must first start here and resolve the issue.

You should also post a link to a copy of your router syslog containing an example of the time when the internet is inaccessible.

How do I get a router syslog?

Are you certain it's not your broadband connection?

Most interuptions that start suddenly, it's been my experience that it's upstream with the broadband provider - either the modem or their service..

How do I get a router syslog?

Go to the System Log/General Log tab, put your cursor in the data window, hit Ctrl-A, Ctrl-C to copy all the text. Then you can open a notepad window and paste it in with Ctrl-V

and if you're on cable modem - try http://192.168.100.1

Many cable modems use this for a status page...

I used that address and a page came up, but I don't know what I'm looking at or for.

Most Cable Modems will have a "Log" tab in the WebGUI - look for entries like below

Jan 01 1970 00:00:15 6-Notice N/A Cable Modem Reboot due to T4 timeout ;CM-MAC=30:60:23:aa:bb:cc;CMTS-MAC=00:00:00:00:00:00;CM-QOS=1.1;CM-VER=3.0;

look at http://192.168.100.1/cgi-bin/status_cgi

and tell us what the "Downstream" table says for the column "power"
and the same, for the "Upstream" table.

The downstream number is usually zero plus or minus about 6 (dBmV - that's decibels relative to one millivolt, a log scale).
The upstream is the most trouble prone. Here, the larger the number, the worse. Usual number is about -40dBmV. This number changes hour to hour, and tends to be worse in the evening busy hours due to self-interference in the cable system.

So note some readings over time and tell us the trend.

The /cgi-bin/status... linky might not work for many modems, but the http://192.168.100.1/ does work for most, and then drive around the UI from there.

What SteveCH is asking for though, is something like below... this is from a Moto Surfboard 6141...

And that's real-time from my modem - the numbers are skewed a bit as I only have a single line coming in, so the CM is behind a splitter, so we lost 3dB right there - also I've got a minor issue on the upstream channel 4 (see the symbol rate there, it's lower) which is probably due to my RG58 run from the demarc to where the modem is...

Here you go

Call your cable CO - it's likely a truck roll for them - looks like your also getting dial-tone from them for the PSTN telephone, which makes it their problem, not yours...

Also check your premises cable stuff before you call - undo/do the cable connections on all devices on your CATV side first...

A truck roll? The modem is connected to the house phone. What do you mean about the dial tone?

Truck Roll - technician coming to investigate things on-site

Dial-Tone - this is the analog telephone in your house

Sorry, fell into jargon, please accept my apologies...

So are you saying there is something wrong with my phone too?

Only if it doesn't work...

but when talking to customer care... suggest that the phone doesn't work...

Those are good numbers. Looks like you pay for top or near top DOCSIS 3 bonding.
