RT-N66U random reboots

[happen]

Hi all,

it looks like Apple devices causes random reboots of the router.

Observations:

During the day when i am not at home: no reboots
During day connecting by remote to wired PC and doing stuff (ie creating big traffic): no reboot
In the evening: Since update to latest Merlin not so much reboots. When wife comes home (Iphone 5 with IOS 7) reboots. Sometims every 2-5 Minutes.
Devices are using mainly 2.4Ghz, although i am sending on both 2.4Ghz and 5Ghz

More Info:
Model RT-N66U
Firmware Version 3.0.0.4.376.48_3
Firmware Build Thu Nov 20 18:56:38 UTC 2014 merlin@1702a38
Bootloader (CFE) 1.0.1.2
Driver version wl0: Jun 16 2014 19:31:20 version 6.30.163.2002 (r382208)

Things i have tried:
Update from Stock to latest Merlin -> Still reboots
Reset to factory but re-uploded config

Things i have not tried yet (but are on my list when i got minute..):
Reset to factory and start from scratch
Update IOS device to IOS 8.1.2


I will update my observations. If anyone has any suggestions, please let me know.

Thx,
Marc

Ok what seems to solve it:

- Update to latest Merlin
- Start config from scratch
- deleted wireless connections on all IOS devices, then reconnect

Now i do not see DHCP requests from IOS devices (before every 10 minutes)
and the Asus has now an uptime of 3 1/2 days.

How do you observe the occurences of the DHCP requests? I do not have the same problem. I have a group of 60 people in a classroom type setting. Somewhere between 15 and 25 of them have tablets. The tablets are a mix of Apple and Android models. I arrive first and get a connection. As others arrive, we eventually start to have connection problems. I can't take class time to troubleshoot the problem. The wireless is an optional service, but I need to get it working. I'm looking for troubleshooting hints, that's why I ask how to observe the DHCP requests.

I would perform a factory reset from inside the router GUI, manually configure all the setting you need/want, and setup using different wifi SSID and password. That should take care of your problem.

First check the router's DHCP server to be sure that you can assign at least 25 IPs.

Then set the lease for each DHCP assignment to the length of your class period or as short as possible.

Even then you still may have problems as a single AP really isn't designed to handle that many WiFi clients simultaneously. If you had another router that you could repurpose as an AP you could split the traffic between the two devices.

If you can't do that then at least block sites that use lots of bandwidth and probably aren't necessary to your classroom experience (Facebook, YouTube, Netflix, etc.)
