I would like to submit as much information to Brainslayer as possible in regards to our common issue:
Frequent and Automatic Self-Reboots

I know many of you have posted several times about this already, but I think having all the information in one place will help.
I'm sure Brainslayer is extremely busy with all the current models he supports, but if there are enough of us with the WRT1900AC v.1 who would benefit from a special version of DD-WRT then it may be worth it.

Personally, I would love to have a DD-WRT build with the 4.4 Kernel similar to LEDE:
https://davidc502sis.dynamic-dns.net/snapshots/Kernel_4.4/r4707/targets/mvebu/generic/

Also, I plan to make a small donation October 25 when I get $. I am ashamed to say this will be my first donation to DD-WRT.
While it is not necessary, I am sure it will be appreciated and deserved - regardless of whether or not we get our own build.

If you do decide to donate:

Thank you all very much!

My experience with any build past 31924 has been:
Random reboots begin usually after 40 hours uptime, but have started much sooner
Get more frequent after 3-4 days to the point of many times daily
Are always precluded by a loss of all connectivity with no abnormal LED indication
Seem to begin and occur more frequently with OpenVPN Client (other services?) enabled

Agreed, thanks for posting!

BS - Is there a specific log you would like us to capture and upload that will help gather the info that is needed to diagnose the root cause of these issues?

For anyone with a Windows PC. You can use Syslog Watcher 4 to capture the Syslog in DD-WRT.
It’s very easy to setup/configure and it’s free.

I do not use a VPN service so I don't know about that. I can confirm the rest of the symptoms.

Could this issue be related to the router running excessively hot?

mine is running pretty hot: CPU 67.4 °C / WL0 56.6 °C / WL1 66.3 °C

No. It’s an issue with the 4.9 Kernel. My router never goes above 47°.

I know it seems excessive, but there is nothing abnormal about your router's temperatures. I just have external fans on mine.

Yeah, it seems to me that it's time that I moved on from ddwrt if I still want to use my router. Kong abandoned it and BrainSlayer has effectively done the same since the router cannot run these builds without rebooting. I appreciate the effort and understand they cannot dedicate time to fixing a problem with one version of this router.

I may try the July Linksys build, but I have my doubts.

Thanks to all!

If you are really a fan of the WRTxxxx hardware. Id would say it might just be best to pickup one of the v2 hardware. Might find it cheap on ebay, then offload your v1 hardware on ebay to recoup the costs.

As far as I can tell there are no negatives to the v2 hardware that is sometimes the case when manufacturers cheapen devices to gain more profits. Linksys had a prior history of reducing RAM and Flash storage on newer revision devices, but this is not the case of the v2 hardware. In this case it appears the v1 hardware is the one that has issues.

When you actually look at the hardware on the inside of v1 vs v2 hardware. The v2 devices seem more like a finished product. Wifi has been integrated into the mainboard. On the v1 hardware, the wifi is a separate daughter card almost as if it were a prototype device that they were rushing to get out the door.

I haven't seen wifi daughter cards in routers since the early days of linksys when they were a small company. Back then it probably was cheaper for them to pick up off the shelf mini PCI wifi cards and just integrate that into their product. Especially if you don't yet have engineers who can properly layout PCBs for RF. Back in the day I had a linksys WAP11 that had a PCMCIA wifi card inside the AP lol.

http://wireless.gumph.org/articles/wap11-insides.html

I believe in linksys's early days of integrating routers and APs together, there was a model that shipped with no wifi, but had a PCMCIA slot on the back that you could upgrade to wifi by sticking a linksys branded wifi PCMCIA card into the slot. Just tried to google for it, but couldn't find it. Probably wasn't a very popular product in the early days of integrating everything.

I remember way back having a 4 high stack of a BEFSX41 router, WAP11 AP, a WSB24 power amplifier for the AP and an EZXS16W 16 port switch.

That was the awesome thing about that form factor they came up with, everything stacked nicely. They also had a cable modem in that form factor as well, but it was not supported by my cable ISP at the time

This is not hot at all. When I was running my wrt1900ac v1 is was always in the 70's. Linksys OEM firmware had the fan control for on at 85 and off at 80 by the way.

My wrt3200 is currently running at 83.2 degrees with 2 streams running. No I am now worried.

experienced wired issue with my Kong Build 01/08/2017 build I have had since beginning of the year, an it appear very stable. Yesterday, I came home and noticed the wifi is gone, and the router kept rebooting it self for hours so frustrating, definitely no heated coz it's fanned and the physical feel is cool. I got fed-up that I installed BS 10/10/17 same issue. Hence I concluded it couldn't be the firmware. Then start playing with routers ports, I removed every three devices directly connected to the router except the modem (internet port) and 8 ports switch connected to port one of the router. So far it has been stable for 8 hrs.

Wondering if anyone have such an experienced and what have done to cure the issue.

Also, I do I obtain a log to assist developer to trouble shoot.

Kong does not support the WRTxx00 series anymore, so you're probably not going to get anywhere with his builds.

Best bet is to flash the latest BrainSlayer that works good for your hardware. 31924 for the v1 hardware and everything else should work pretty good with the latest current release.

See if the issue is still reproducible. If so then you could submit a bug report in for BrainSlayer to look at.

Though my 1st though with what you describe, if you have made no firmware or config changes to the router in some time and it just starts acting up. It sounds like you might have a hardware issue.
