Asus RT-N66U keeps rebooting

[mccatys]

I just upgraded to 3.0.0.4.374.720 and this was the first firmware version which makes my RT-N66U ver.B1 enter a forever resetting loop. I also tried 3.0.0.4.374.33 (Merlin Build) - same issue.

I did the NVRAM reset before and after, unzipped the file and everything else, so please don't ask if I flashed it ok. Everything is working for a day or two and afterwards it crashes. Sometimes out of the blue, but most of the times when I connect from the WAN side and change something.

I am using quite a lot of options, including VPN connection. I had a connection with it today via ddns asuscomm.com - https on port 8463, but didn't modify any settings, just checked clients list. Don't know if this is the cause, but previously I have tried using ftp with 2 x 1.5 Tb Samsung Story Station hard drives connected to it and enable DLNA server and FTP server on them and no matter the firmware - sometimes it loses the USB connection or it keeps showing the hdd as "unmounted". I just bought a separate NAS (Zyxel NSA310) just to ease the load on the router, because I thought this was the cause of the resetting cycle.

I don't know what number was the original firmware I had when I bought the router, but can anyone point me to an older (STABLE) firmware download site?

I just want to revert back to the much older version and see if I get the same problems. Oldest version on Asus website (3.0.0.4.276) doesn't work either. Since I upgraded the original firmware version (which number I was so "clever" not to look at) I keep having problems with my RT-N66U. Please help! Thank you!

Hi,

First of all you should open another thread for this as it's not only realted the specifc version of the firmware as discussed here.

There are only a few situations where Linux (remember your router firmware is based on Linux) goes into panic mode, which could result in reboot.
The first (and main) reason is an out of memory situation!

Did you already consider to setup a swap file and to monitor the usage of the swap file in conjunction with the reboots (or then not reboots)?

With kind regareds

I agree w/ @joegreat and would say start a new thread, don't try to trick your router by using HTTPS by way of dynamic subdomain redirect, and try the features you are using one at a time, shake down for stability and performance, then slowly stack them on top of each other (testing for stability & performance with each combination of features along the way) to help isolate what's going on. Very difficult to untangle all at once, on any firmware.

Swap file

I just read this link regarding swap file:
http://www.dd-wrt.com/wiki/index.php/Linux_SWAP

Did my research - bottom line: it's a little bit over my league Or at least over the time I am willing to invest in making the RT-N66U do all the things it's supposed to do (as advertised on the box when bought from the shop, right?)
On the other hand I am willing to invest some more money, instead of time.
I am willing to cut loose all the ftp and dlna and just bought a separate NAS (Zyxel NSA310) which is going to be delivered at my home tomorrow and which should take over some of the load. Therefore, right now I just need a blunt router (well... perhaps also a VPN server because I spend a lot of time in airports and a Wake-on-LAN option from time to time, 2 guest networks: 2.4G and 5G, MAC filtering... and the port forwarding I believe I will need for the new NAS ftp to be available from WAN side). Hope I didn't forget anything...

Therefore, my problem now is that no matter what new firmware version I am loading, the router keeps crashing after a couple of hours or 1-2 days. I need it to be up&running at least 30 days, without any human intervention or at least to be able to solve any problem by remote access only.

I don't have the original firmware, which (I might add) did a wonderful job back at my parents house, having hundreds of days of uptime with no restart needed. The router is version B1 and was bought more than a year ago and has been running its stock firmware until I moved it to my new place a month ago. I have been struggling to get all the things I need up and running only with this router which is supposed to be almost the best on the market and should cope with everything, right? (...hate the marketing strategies nowadays...!)

I just installed Shibby's tomato-K26USB-1.28.RT-N5x-MIPSR2-112-AIO-64K and will see until tomorrow morning if this one still stands. Until now, for 30 minutes, it's ok. However, if it crashes I really think I need an older firmware version and that's what I'm asking out here: a simple solution, fast and not time consuming at all Flash the damn thing once and for all and let it rot for ages on the wall Please help me do that and let it rot?

I have this same sometines in last merlin
Cyle reboot or just reboot.
If you main memory not used i think you don't need a swap partition or file.
I research reasons but all fine in logs, i can't find it.
Before i think it's only my problem
