Internet dropping frequently WRT1900AC David C build

Owengerig · June 25, 2019, 8:35pm

.
During this time, my modem lights show connected (when calling tech support they also show me as connected)
Im still connected to my wifi and lan just no internet access
after reboot of the router internet is restored

i noticed these 2 log statements and thought they might be relavent

Tue Jun 25 13:16:25 2019 daemon.notice hostapd: wlan1: AP-STA-DISCONNECTED c0:e8:62:cc:c3:00
Tue Jun 25 13:16:25 2019 daemon.info hostapd: wlan1: STA c0:e8:62:cc:c3:00 IEEE 802.11: disassociated due to inactivity

I googled around and found a recommendation to set disassoc_low_ack to 0. However that was last week, and the problem is still happening. prior to that i replaced my modem thinking it was bad.

So to be more clear, you have a device that looses WiFi?

Try changing channels.

sunnymonday · June 25, 2019, 10:00pm

It will be a good to give your 2.4Ghz and 5Ghz a different SSID (sorry, just noticed SSID is different). In case you have no internet, you can easier narrow down which band is at fault.

For example, your client could still be holding on to 5Ghz when the signal is real bad and does not jump over to the 2.4Ghz.

Also, I would set up VHT40 on 5Ghz to do some thorough testing and check VHT80 later to see if performance was better or poorer.

Hegabo · June 25, 2019, 11:19pm

Well, if you mean that clients connected to the router via Ethernet cable also lose internet connection at the same time, then WiFi isn't probably the first thing to look at.

What kind of connection do you have between the modem and the router?

anon50098793 · June 26, 2019, 11:24am

Also, what is your interpretation of frequently...

Every 20-40mins?
3-4hours?
Between a few hours and a few days?

Kinda important to establish this to move forward... Should have been something the ISP emphasized?

Owengerig · June 26, 2019, 1:09pm

frequency is a bit hard to pin point but i would say once every few days, occasionally multiple times in a day.

yes even Ethernet clients experience the issue (lose internet connectivity)

there is an ethernet cord going from my SB5101 modem to the linksys

Owengerig · June 26, 2019, 6:46pm

idk if it matters/helps
but it just happened again. that mac address has changed though

lleachii · June 26, 2019, 7:03pm

For the WiFi log issue...did you change channels?

Owengerig · June 27, 2019, 11:57am

no, because its happening on the lan/ethernet clients and the fact that wifi connect/signal isnt dropping; its just the internet connectivity

anon50098793 · June 28, 2019, 6:43am

do you think there is a correlation in traffic volume rather than time?

Owengerig · June 28, 2019, 12:28pm

i dont! but i suppose its possible

Owengerig · June 28, 2019, 6:16pm

it happened again without that errror so i guess its unrelated
but i dont see any other indicators in logs to investigate further

whats weird too is that the log indicates internet went down at
Fri Jun 28 11:04:52 2019 daemon.info watchcat[5530]: no internet connectivity for 1081 seconds. Reseting when reaching 21600
but on my laptop via wifi it was more like 11:10 when the internet dropped
there isnt a time difference between the router and my device its just some delay (idk, i cant explain it)

Owengerig · July 8, 2019, 6:55pm

purchased a new router Zyxel Armor Z2 AC2600
so far it seems that the problem has gone away , must have been a component going bad on the linksys

Owengerig · July 16, 2019, 5:52pm

putting here for reference
i think this was the actual root cause

https://superuser.com/questions/1460529/occasional-loss-of-internet

after a few weeks now i can 100% confirm that my isp was having problems with my docsis 2.0 router, upgrading to a 3.0 modem fixed the issue
