I deleted all our subsequent posts.
I'm sorry I chimed in.
Let's hope brainslayer addresses your concerns. _________________ I am far from a guru, I'm barely a novice.
On my TL-WDR3600, the unit on this build kept randomly rebooting itself. All clients in the household would lose connection (obviously). I did some poking around, and noticed that the Load Average on the status page is up to 80-100% when barely any Wi-Fi or LAN traffic is being sent/received. Someone else in this thread had the same issue:

Router: wdr4300 v1.7

Errors: random reboots, high usage cpu after boot
At first I was skeptical because everything was working fine, but this problem cropped up later on down the road. The 3600 is practically the same exact thing as the 4300 (minus 1 antenna), so I suspect that both of us are having the same issue. The fact that it's intermittent probably means that arrowdau had this happen at the beginning and maybe not at the beginning on mine, but the CPU on mine started intermittently ramping up all crazy at some other point in time.
It appears that the CPU gets overloaded to the point at which the kernel probably panics and then the unit reboots. Or maybe it was overheating? This happened anywhere to twice a day to once every three days. I reverted back to r30880 std (11/14/16) and Load Average hovers between 3-7%. I am hoping this can get fixed in the next build.
I installed OpenWrt ChaosCalmer 15.05.1 on the WDR3600 and the high CPU utilization/router reboot issue appears to have vanished. So far there are three people at least (that I've seen on this forum) that are having issues with the WDR3600 having the same reboot and/or Wi-Fi drop issue. Here's another person that just opened up this thread today:

Hello,
My router's wifi keeps dropping out while streaming from my NTFS drive which is attached to the router.
Is anyone else experiencing this issue?
I'm using the latest build v3.0-r30949 std (12/15/16) but had the same issue with the Nov and September builds.
The issue he describes above could be related as his Wi-Fi is dropping out, yet I don't have a NAS that's streaming movies connected via USB to the router. This issue started in the same build time frame as thecrater descrbes above.

I'm looking at openwrt because I can't get entware to install for some reason. I wanted to run iftop/dnstop!.
Anyway, what do I need to move over and test openwrt.
Just the webrevert then openwrt ?
looking forward to an update so I can get both radio's up and running properly, just using 2.4gig at the moment.
And by the way, I'm not getting the drops your talking about on 30880 I've had up times of 14 days etc.., are you running both radio's out of intrest ?

I'm running both radios, yes. And yes, you can't flash DD-WRT > OpenWrt without first going back to the factory firmware (webrevert image). There may be a shortcut to bypassing that step using mtd over SSH or telnet, but I'm unaware of any info on if it's possible or not. I haven't flashed DD-WRT on more than 10 different model routers over the years (I keep my routers for many years until they practically die), but it looks like on some model routers you may be able to flash between OpenWrt and DD-WRT easier than on the WDR3600. I've also bricked the 3600 before and had to recover with a UART. It's one of those routers that imo works great if you don't fuck with it too much. Once you start toying with it, it can give you a real hassle. In other words, if it's working I think the best thing to do is leave it alone. I will get a better router when this one finally goes, but who knows. That may not be for another 5+ years.
Going from OpenWrt > DD-WRT requires additional steps in BusyBox. After you flash the OEM firmware back using the command below, subsequently you would flash DD-WRT:
Code:
cd /tmp
wget http://www.example.org/original_firmware.bin
mtd -r write /tmp/original_firmware.bin firmware
If you want to remove DD-WRT, you should write to the device "linux" instead of "firmware":
Quote:
mtd -r write /tmp/original_firmware.bin linux
Anyway, on the DIR-615 i1, OpenWrt's Luci kept spitting out this error message:
Quote:
No password set!
There is no password set on this router. Please configure a root password to protect the web interface and enable SSH.
Go to password configuration...
What was strange was that the redirect to the "No password set!" page started appearing the more I tried to configure the router, and it doesn't do the same thing on the 3600 with no password set. On the 615 i1 I tried setting a password to see if it would shut up but the same exact behaviour ensued. The more times I went into the interfaces section (were're still talking about OpenWrt), the more it kept redirecting to that page. More than once, it completely blocked everything I was trying to do in the GUI and the only way out of it was to reset the router with the reset button, pull the AC and replug, or go into the flaky D-Link emergency management mode and flash back the D-Link firmware followed by flashing OpenWrt again. On the 615 there is no TFTP server either.
Any one of those steps worked, depending on how "stuck" the router was and that varied depending on whichever way the wind was blowing. Bottom line is that the 615 i1 was problematic with OpenWrt Chaos Calmer 15.05.1, but the WDR3600 seems to love it. It's slicing through traffic like it's butter, not that DD-WRT ran bad on the WDR3600 either when it wasn't dropping clients.
Thank you so much for your invaluable info, especially on reverting back from openwrt.
Anytime. I found that with OpenWrt on the 3600, if you have Luci open in more than one browser tab you will get the password authorization page over and over again like I wrote above. So that may or may not have been the issue with the 615 i1.

I have three different versions of Iphones (6+, 6SE, 6) that can only connect to 2.4 GHz with "LEGACY" channel width but not HT20 or HT40.
One of them tries to switch to HT20 but fails and falls back to LEGACY.
They work fine on 5GHz.
Other mobiles and computers work fine.
Are there any settings I should pay particular attention to to make Iphones work?
I tried OpenWrt on my WDR3600 v. 1.5 for a few days and it turned out to be problematic.
The high CPU usage issue that was occuring with DD-WRT (see my comments about this issue in this thread) on the WDR3600 appeared to not be happening with OpenWrt, but the 2.4 GHz interface was shutting down all by itself after 2-3 days of uptime. After running for a few days, all 2.4 GHz clients would lose connection and upon logging into LuCI, I would see the 2.4 GHz interface was disabled.
This happened a second time, so I ended up flashing back DD-WRT on the router. The test was to see if OpenWrt ran any better on the WDR3600 and the result was it doesn't. Currently in DD-WRT, I have ath1 [5 GHz] disabled to see if that solves the high CPU issue.
Hi all,
Any news on fixes for the CPU issue in the latest builds? I see that BS and Kong have been making a lot of changes but I don't know if the CPU load problem has been fixed or when the next release is due?!
