Internet connected / Time synchronized every 6hrs drops connections

Greetings to one and all,

Been happening for months now, I can time it to the second as to when my IPTV locks up lol I've checked logs and seen that I had an intruder through the Upnp (so disabled) figuring that was causing my internet reset/dropping wifi etc. After seeing a couple DDOS attacks the intruder used as retailiation for not having entry, I cleared the logs and hoped that was the end of the problem but even with no more intruders but now i'm seeing the trigger/time of when my internet is dropping momentarily and causing havok with my IPTV etc.

- I've called my isp, had them check the line, no problem between them and my modem... so, its something in the router that might need tweaking/changing that could have been reset since updating firmware possibly?

Here is my logs everytime this happened, my dhcp would reissue ip addresses too (I've removed the DHCP/cleaned them up for easy viewing), :

- I have an R8000 X6 AC3200 with Firmware Version V1.0.4.28_10.1.54
- I've reserved ALL my devices attached/wireless ip so no dhcp should be triggered any further in logs.
I've love any advice cause i've searched the forums and internet and other than "hard reset", not sure if there is something else I can do?

Thank you in advance,
Sith

Re: Internet connected / Time synchronized every 6hrs drops connections

IP address renewal happens all the time on networks. A renewal of IP address of the WAN interface on the router should not cause a pause in the IPTV. I would look at the router and specifically the router firmware. It might be worth the effort to go to an older version of the firmware. Do you know of a version that seemed to work for you? If so I would reinstall that. You could try a hard reset, but not really sure what that would accomplish in this case, but who knows?

Re: Internet connected / Time synchronized every 6hrs drops connections

Well, those lines are NOT drops.

 

My R8000 log is similar:

 

[Time synchronized with NTP server] Tuesday, May 21,2019 16:19:22
[Internet connected] IP address: 97.xxx.xxx.xxx. Tuesday, May 21,2019 16:19:21

 

Leases are set by the backend of your ISP's configuration for your IP Address. Totally OUT of your control.

 

If you look at the ADVANCED tab, and click on CONNECTION STATUS, you'll see the LEASE time, mine:

 

Lease Obtained 0 days,20 Hours,29 Minutes
Lease Expires 0 days,6 Hours,5 Minutes

 

My time now is 6:45AM on the 22nd.

 

Do the math, lease gotten yesterday @ 4:19 in the afternoon. This is roughly 8 hours yesterday and 6+ today, which matches roughly the 20 hours and 29 minutes since it was obtained. 6+ hours to go before it will try again.

 

That said, it usually IS normal for a least to be attempted to be renewed at 1/2 the time! It is NOT happening for me.

 

My ISP (Spectrum) it appears as rumors persist is transitioning to faster base service and seriously upgrading the backbone for GB speeds as well. So recently my IP Address changed. Before I was having a VERY short lease and at 1/2 the lease time it was getting renewed:

 

[Time synchronized with NTP server] Sunday, Feb 17,2019 03:33:30
[Internet connected] IP address: 67.xxx.xxx.xxx, Sunday, Feb 17,2019 03:33:29
[Time synchronized with NTP server] Sunday, Feb 17,2019 02:07:35
[Internet connected] IP address: 67.xxx.xxx.xxx, Sunday, Feb 17,2019 02:07:10

All this is out of your control.

 

As for logging, especially for attacks, I think NG logging just sucks, period. If you Google the attack type you had almost ALL results that mention a router will be NETGEAR!!! I'd say at least 99% of them are FALSE POSITIVES. Google the IP Address and most of the time you'll see that they are related to sites you visited or connected to something that is active on a device.

 

I think it is poor handling by the CPU of the router. Basically, usually under load (a lot of active Internet connections) it loses track of what LAN IP address was expecting a TCP/IP packet. When one comes in that it wasn't expecting, it thinks it is an attack and logs it as one depending what is in it. You would not even notice this usually. The device waiting for a packet realizes it didn't get one in a very short period of time and requests it again which the router now 'remembers' and it comes in very fast. Device is happy and continues. Might see a second pause or so in a video, a web page load, or never notice it.

 

I have seen spurious devices trying to attach with UPnP on myself, but it wasn't an attack.

Re: Internet connected / Time synchronized every 6hrs drops connections

Thank you for the reply, 

Lease Obtained 0 days,12 Hours,0 Minutes
Lease Expires 0 days,6 Hours,59 Minutes

okay, i understand the lease renewal at half time, that fits what's happening here but my problem still exists that at every 6hr interval my iptv will freeze on my 5G (high end android boxes) and its annoying as heck! I was hoping for an uninterupted experience, is there anyway to fix this so it doesnt interupt my IPTV? I mean a router shouldn't freeze devices while doing an ip renewal.

Re: Internet connected / Time synchronized every 6hrs drops connections

If only IPTV freezes, and no other devices, then the problem is probably with IPTV.

 

This appears to be a common problem when I Google'd "iptv will freeze"? Might want to look at some of those.

 

There is a difference also between freezing and buffering. First one mean it completely stops and doesn't change, the other it stops and then starts again. Those are two different problems. Freezing is locking up and you have to reboot or restart, the other pauses and then jumps ahead and usually indicates either slow internet that can't fill up the buffer and then starts when new frames come in until it happens again.

 

Possible QoS could help here IF Internet speed is slow, or hurt if Internet speed is 2-300Mbps or higher.

Re: Internet connected / Time synchronized every 6hrs drops connections

Download - 43.50Mbps
Upload - 10.98Mbps

Qos is enabled. I've had the R7000 and never had issues with streaming with the same IPTV service that i've had for years now. Same speed I've always had from ISP. I've never had issues streaming/multiple devices on my network all running at once, ever, till now. 

I'm personally thinking that the router as robust as the AC3200 R8000 should be able to handle an IP address renewal at HALF interval without loss of any connection before it fully expires and actually loses connection without IP renewal period. I mean nothing is actually changing since the IP address isnt actually running out for another 6hrs AFTER the half way renewal. IF anything, it should be once a day IF my ip addy changed but it doesn't.

Come on Bill... on your 'crap firmware' kick yet again?

 

If this were a F/W problem then ALL devices would suffer. It appears it is ONLY IPTV. He did say though it work before with an R7000.

 

We don't even KNOW if this KB article was followed setting IPTV up, https://kb.netgear.com/29911/Configuring-VLAN-IPTV-setup-on-your-Nighthawk-router?

 

Try and help solve the problem before blaming the F/W please.

Re: Internet connected / Time synchronized every 6hrs drops connections

Bill, thank you for giving me an option to try. I've found the version before the latest and backed up the FW to that one and will give that a try. Hey, it can't hurt. I've not posted here for nearly 2 years, and there's been F/W updates so perhaps one i took was partially corrupt, you never know but I like the idea of ruling out F/W. I'll know tonight if my TV glitches out/back if its fixed it. Then we can try something else as I dont want to give up on this nice router.

IrvSp - I only said i notice it with my IPTV, normally i'm not on any other devices while i'm watching tv but the DHCP log in the router also shows that not only my wifi devices are getting their ip's renewed but my hard wired devices are too. 

Thank you both for helping, I really enjoy and endorse Netgear products to my family and friends cause I am their IT guy (since I taught IT for a living before my retirement). So credentials, i've got them too 😉 MCSE/A+/Cisco Certified etc

That is quite normal... and it can happen for many reasons. Such as the PC going to sleep, or waking up from sleep. Even when booting it gets logged. Sometimes even when 'calling' home to get/check for s/w updates. Many times it is just verify the IP Address.

 

Here is my log entries:

Some of those are clearly (I know what is on what IP Address) iPad's waking up, some are our phones powering on, some are printers turning on. All these are wireless of course, no wired connections.

 

The ones ending in .45 and .50 are the PC's. One has a NG A6200 USB adapter and it has a bug where it will on occasion quickly try again to get an IP Address. W10 specific problem with the driver.

 

When I had wired devices it was similar.

 

All normal.

Re: Internet connected / Time synchronized every 6hrs drops connections

Don't know if this is possible with the IPTV you have.

Thought is can you hard code an IP address on the IPTV? If so then it would not be making dhcp lease renewals. If you can and want to try this make sure the IP address you choose is outside of the dhcp range. Also note the gateway and DNS IP addresses as you will need them. Probably the same as the router. Netgear routers do not do a ping ahead, last I knew, before assigning an IP address so if within the dhcp address range could wind up with a duplicate assignment. I hard code my NAS and Rasberry Pi Pi Hole.

Re: Internet connected / Time synchronized every 6hrs drops connections

okay, last night, i had a convo with roommate, he told me his wifi was sporadic for a few months now and his phone wouldnt connect to the wifi. 

I checked my phone... funny, mine wouldnt connect either and the password was not accepted (even though i knew it and using correct one).

I took Bill's idea and flashed back to previous firmware and immediately my phone, roommates phone connected to the 5g wifi. I waited up last night with my IPTV on to see if it would glitch at the 50% renewal request... IT DIDNT GLITCH. 

So, in conclusion, Thank you Bill, your suggestion fixed my problem that I was having. Other than a few ddos attacks since my turning off upnp, my internet/router issue is resolved. 

Thank you again Bill. Its people like you who give a possible action/solution that get things sorted out. Alternative is just lecturing and preaching, which does nothing but have products thrown in the trash and people buy other companies products to solve the problem.

AGAIN, Thank you Bill. Keep up the good work.

You might want to try the latest f/w again. It is possible you had a bad install. That f/w is solid.
