Agree. The easiest method = check the router log time stamp. (make sure NTP is enabled, Time Settings)

If the router reboot itself, check the router log earliest time stamp that changed into actual time when NTP successfully synchronized.

Default time starting point is 2017-01-01 00:00:00 for 1.1.3 Build 20180124 52299 (EU). By checking the time stamp in the log where it synch into actual time, you will know when is the last time the router reboot itself.

Or use the mail function too? Auto mail every 1 hour. Then check the log on time stamp.

For me, i just check the External IP on Phone Ookla speed test, see attached screen capture.
if change = Router rebooted

"You can see the router log, apart from public ip change."
But my public IP address is still the same.

yes, not very reliable method, once in a while reboot also will be the same. but most of the time it change la.

.. Guess I'll remain on current firmware as it's been stable so far.

your C1200 have been switch on 24/7 for how long? never single self reboot?
you are on (C1200v1_eu-up-1.1.1 Build 20180101 rel.66049(Beta)) FW right?
can you share your setting, what make it stable?

Mine's running FW V1.1.3 Build 20180124 rel.52299 (EU). It's a firmware that was applied via online upgrade in the web UI. I believe it's been on for at least a week. WAN IP remains the same. I've had it on longer than a week. Before I can be watching Netflix or Youtube via TV app while some heavy p2p goes on PC or Media box and suddenly it'll randomly reboot. Sometimes more than once a day. Since flashed this firmware. Not a single occurrence. Lucky.


As for settings..
Router mode.
IPv6 is enabled and working.
Using OpenDNS for both IPv6 & IPv4.
Default DHCP Server settings.
Wireless:
*2.4GHz is on High TP & Channel 13 offers the least interference at the condo, Auto channel width.
*5GHz is also on High TP, a/n/ac mixed, Channel 36 has no interference whatsoever, auto channel width.
Guest Network disabled.. No USB/Printer connected.. Have other wireless devices for such.
All boxes ticked under the Nat Forwarding >> ALG area.
UPnP enabled, DMZ disabled
Both Parental & QoS settings are disabled.
SPI Firewall enabled, DoS protection disabled
ARP Binding and Access Control disabled
No VPN Servers setup/enabled.

your setting is very similar to default.
i also try that FW before using similar setting except having more feature turn off. it rebooted during halfway internet banking while no other heavy usage and Unifi TV was off. got piss off and replace with Archer C7. now so far so good.

Yeah.. Close to default works and so I left as is.. I too have read about so many disappointed by the router. Guess mine was one of the lucky batches.

That firmware produced the most uncommanded reboots for me.


I remember you mentioned previously that you rarely monitor the WAN IP, so how do you know for sure it didn't reboot?
Leaving it on for long periods doesn't mean it never auto-rebooted during the night or when your not using the internet.
All, it takes is a couple of minutes to reestablish a connection once it reboots...

Well, after i mentioned such and noticed so many people getting the same problem.. I offered to daily monitor the WAN IP.. Each night as tonight, I check and no change. I don't leave any browser cookies or cache behind as all are cleared with each browser exit .. so it can't be remnants. I've also explained that I could sit watching TV and cuz the router is right there beside the TV, easy to notice if it reboots. Not just me, other house members. I'm a night owl and most days of the week I'm home telecommuting on the PC.. So I'm sure I'd notice if I suddenly lose internet connection in the middle of a conference call.

Ok, got it...

After 22days..my router rebooted...how i know it was reboot..since i set vpn..so the public ip still same until it is reboot n wan ip is change..and i cant vpn anymore.22 days uptime consider ok la..

if not rebooting during halfway trading stock ok la.
if rebooting when entering order then no good d.

Haha... Really bad luck if it happens then.. By the time it's done rebooting.. Window closed..

So, anyone? who test the new beta firmware? How is the performance of the router?

[EDIT]

Nvm, I found it...

Give up on C1200 d.

Performance more or less the same as official EU firmware.
Reboot part --> Unsure, as it still haven't reboot since I installed it yesterday...although with a bit wifi channel modification.....


Eh, how many 5ghz channel available for your new toys C3150v2 ?

channel 36 and auto inclusive. . Having 9 including auto channels in total. So far i am a happy user of this router. Never faced a single issues. Special thanks SilentVampire bro for suggesting me to test this router. Those who wish to buy this router, do upgrade your firmware to the latest version. Because you will face some minor difficulties of getting an error to setup the router successfully.

Can refer my personal review on this router here



[attachmentid=9667832]

I hope they really find out a possible solution for the auto-reboot part. I felt pity to those who have to depend on stock isp router and those who tight budget. I felt surprise that, the router that received many negative reviews, DIR850L performs better than c1200. Awesome hardware, poorly coded firmware.
