Nighthawk X6 - Model R8000 INTERNET repetitive disconnects with no log
Hi my router worked well after the last firmware update some months ago. Firmware V1.0.4.12_10.1.46 . Then about 10 days ago it has started disconnecting very frequently and repetitively, and reconne...
Hi, thanks James. I did install it earlier today.
I imagine that it must be related to the security issues in the news.
supposed to allow auto update of the firmware too.
Hopefully all goes well and keeps hackers at bay.....
But also this morning I had the visit of my 3rd technician and I am hopeful it is going to be finally working well.
First technician did some connections tightening and changes and changed my modem to another thomson. Not better five minutes after he left
I went to mediacom shop the next day to get another modem, arris, better.
2 days later second technician was helpful finding out and telling me there was a capacity problem sometimes (that appears in logs at the provider) and that he was going to ask to be looked at.
Then nothing happened during 2 weeks and still internet often bad.
No news about capacity increase when I was asking and it did look like problem was still too present to be only that.
Called and complained last week and Surprise: Third technician rings at the door this morning today.
I think he did a good job, very methodical, replaced some cables that were dammaged from ?rabbits, checked every connection and splitter. changed several. Noticed also I was using a ethernet cable from modem to wifi that was maybe a limiting factor in the speeds and not related to the drop we think
Very happy with him. Very hopeful. No issue for the last 12 hours and I saw the firmware and updated.
So modems might be more or less performant with a bad signal but I think 2 main factors to my problems have been
-coax dammaged and connections loose or deficient (hopefully all fixed for the moment)
-maybe capaicity
To have an increased capacity provider must do increase of capacity and it might not happen soon but I will be challenging them if problem
Also I have a 8 channel modem, might go and buy a 16 channel one. Hearing it could help.
If I think about the technicians I have had,I have seen others and none was as professional as the one today I think and I had given up on a TV problem (frozen frames) on TV for the last 2 years, getting worse last 2 moths while internet also underwent issues leading to this post.
Will check whether it improved or still happens.
Pretty thankful to the technician of this morning also I have learned a lot thanks to talking to them and this chat. Thankful to this chat too.
Check on the Modem to see if there are any entries in the STATUS or CONNECTION... I don't know what you can see, but sometimes you can see things like Internet disconnect or the modem rebooting or other things in the log like T3 timeouts. All of those would basically disconnect the Internet or if nothing more slowdown your usage of the Internet. Also, if you see the channels that are used you should see Correctables and Uncorrectables. Very high counts should not be seen for these. If you do, it could be line problems.
Thanks again irv5p
in the logs of the modem (DOCSIS )
I see T3 time outs not sure whether meaningful

T3 and T4 time outs can be a problem, again, especially if you see Internet drops at the same time they happen.
First read this data, https://volpefirm.com/docsis_timeout_descriptions/ which describes the different T's...
Next look at my JPG's from my modem. See those 5/2 0:32AM entries, well my Router log has a matching entry:
[Internet connected] IP address: 192.168.100.20, Wednesday, May 02,2018 00:33:04 [Internet connected] IP address: 192.168.100.20, Wednesday, May 02,2018 00:32:54 [Internet connected] IP address: 192.168.100.20, Wednesday, May 02,2018 00:32:44 [Internet connected] IP address: 192.168.100.20, Wednesday, May 02,2018 00:32:25
When the router can't get an IP Address, that is what you should see... and in the case here the ISP dropped the signal for a long time as the service was upgraded.
If the modem is sent to REBOOT mode it can take up to 2 minutes even and you'd see 20 entries like the above. If it is a SHORT interruption however you'll not see it, like a T3 problem (it doesn't always cause the modem to drop the signal, and if it does, it usually tries immediately and then it is so fast the router doesn't notice it.
Me, I'd call your ISP and tell them you see T3 and T4 timeouts on their modem and see what they say? They can usually see the same thing and other back end data and might be able to help.
