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.

As far as 'blocked devices' getting an IP Address, I can't really say? Logic says they should not under any circumstances? That doesn't mean what the router might do? I 'googled' if a blocked MAC address can get an IP Address and can NOT find anything about that, not a single link?
Now if you are using TIME to block, it is possible it is on the LAN and when the time hits, it might be logging it blocked it?
As for seeing multiple entries of getting IP Addresses, I see it SPECIFICALLY with my wife's PC that is at 192.168.1.40 (I too assign the PC specific IP Address so I know I can always get to this even if 'sharing' doesn't work well (which does happen). For instance:
[Time synchronized with NTP server] Friday, May 04,2018 19:09:46 [Internet connected] IP address: 67.8.xx.xx, Friday, May 04,2018 19:09:45 [DHCP IP: (192.168.1.40)] to MAC address 08:BD:43:A5:8C:AA, Friday, May 04,2018 18:57:50 [DHCP IP: (192.168.1.40)] to MAC address 08:BD:43:A5:8C:AA, Friday, May 04,2018 18:57:38 [DHCP IP: (192.168.1.30)] to MAC address F8:B1:56:DD:6A:5B, Friday, May 04,2018 18:30:51 [DHCP IP: (192.168.1.40)] to MAC address 08:BD:43:A5:8C:AA, Friday, May 04,2018 17:45:15 [Time synchronized with NTP server] Friday, May 04,2018 17:43:40 [Internet connected] IP address: 67.8.xx.xx, Friday, May 04,2018 17:43:39
See different time, and one 18 seconds apart...
[DHCP IP: (192.168.1.40)] to MAC address 08:BD:43:A5:8C:AA, Friday, May 04,2018 13:34:28 [Time synchronized with NTP server] Friday, May 04,2018 13:24:23 [Internet connected] IP address: 67.8.xx.xx, Friday, May 04,2018 13:24:22 [DHCP IP: (192.168.1.40)] to MAC address 08:BD:43:A5:8C:AA, Friday, May 04,2018 12:48:15 [DHCP IP: (192.168.1.40)] to MAC address 08:BD:43:A5:8C:AA, Friday, May 04,2018 12:10:51 [DHCP IP: (192.168.1.40)] to MAC address 08:BD:43:A5:8C:AA, Friday, May 04,2018 12:10:38 [DHCP IP: (192.168.1.40)] to MAC address 08:BD:43:A5:8C:AA, Friday, May 04,2018 12:00:52 [DHCP IP: (192.168.1.40)] to MAC address 08:BD:43:A5:8C:AA, Friday, May 04,2018 12:00:31 [Time synchronized with NTP server] Friday, May 04,2018 11:58:25 [Internet connected] IP address: 67.8.xx.xx, Friday, May 04,2018 11:58:24
Some more...
I for the LIFE of me can NOT resolve why this happens. I checked when she wakes up here computer (which goes to sleep, and if sleeping long enough I know the USB wireless adapter seems to disconnect as when she does wake up the computer sometimes the Wireless Connectoid on the Systray shows no connection momentarily) and NEVER correlate those actions to log entries? I don't think it is Windows causing this, and if you run IPCONFIG /ALL you should see LEASE times of 24 hours:
Lease Obtained. . . . . . . . . . : Sunday, May 6, 2018 3:27:23 PM
Lease Expires . . . . . . . . . . : Monday, May 7, 2018 3:27:23 PM
The above is for MY machine, I was out and came back in and woke it up. So it got a NEW LEASE it seems. This PC is hard wired, and it does correlate the time of the DHCP lease to the LOG:
[DHCP IP: (192.168.1.30)] to MAC address F8:B1:56:DD:6A:5B, Sunday, May 06,2018 15:27:23
I sort of have a feeling that for WIRELESS it is different? Possibly it checks periodically to see if it is still connected OR it sense it has lost the IP Address and reestablishes it? Still, I can not reconcile all the DHCP entries in the log to any PC operations.
Secondly, I 'believe' that LOGGING is a very WEAK point in NG's routers. You can't log everything easily. It is possible some logging (like DoS attacks) are completely wrong or incomplete (I've seen ones that clearly have missing letters in what was logged). I'm sort of thinking in this case it isn't a DHCP request/assignment, but the Wireless device waking up and asking the router if it still has the same IP Address and the router logged that as a DHCP request. That goes back to the method old DIALUP and even Cable systems control the DHCP given out. They have a limited pool, and in DialUp of course once you hang up your IP Address is put back into the available pool. Cable, different story, always on unless you power down the modem. Still, Cable uses a server with a limited number of IP Addresses assigned to an area. Let's say 254 addresses. However it is NOT cost effective for them to have a node for only 254 customers. They know not everyone uses the computer at the same time, so for arguements sake lets say they assign 300 users to that node. Now when 254 are in use and no one has disconnected or let the LEASE (24 to 36 hours are normal with a RENEW usually done in 1/2 that time) expire they will look at the LAST TIME USE, and the oldest time last used will be dropped and given that IP Addresss. However, this IS rare. When it does happen the ISP knows it needs to split the node and create a new one.
So what does all this have to do with anything? The PC doesn't really know for sure where the DHCP server is? Under whose control either, so when it comes back to 'life' it will check if it is still its IP Address probably. If it were given away it would get a new one. If you are using a declared IP Address (Static) then as LONG as it is NOT within the POOL of available DHCP IP Addresses (you can set the size of the pool in the router and the highest number should be below the declares fixed IP address or conversely, the lowest number above the last fixed IP Address you used. Other wise you could have conflicts on the address and someone could lose Internet connections.

Possible that the usb wifi adaptor is shutting down if not used for a while when the computer goes a sleep, not sure if it is a laptop or not a laptop would turn off unneeded devices to save battery life when a sleep. Power management settings in windows and the settings of the devices driver software can play in when and if the device shuts down at specific time or even. My does the same thing the wifi usb adaptor must wake up and log back on the wifi network.

William10a, true that can shut it down and cause this. However in my situation that should 'not' happen.
Not only the USB adapters Properties set NOT to allow the computer to turn it off to save power (this is a desktop also) but you must also do the same for both the ROOT and GENERIC USB HUBS... those going off will take down the adapter as well.
All I can figure it the adapter s/w (this is a NG A6200 AC adapter) knows the PC is coming out of sleep and checks to see if the IP Address is still good? Happened on the R7000 and now the R8000. I think logging on both routers leave a lot to be desired, but I suspect it isn't the top of a list NG worries about?

Logging issues have been going on for a while and you are correct Netgear is not worry about the issue either they have other issues to handle which still need attention.
