About once every 36 - 48 hours my router will stop responding and will lock up so that you cannot get to the web interface.  I have to power cycle the device to get it to come back.  When this happens, I can look at the logs and see the following.

Is anyone seeing anything similar or have any ideas as to what to try?  It almost feels like a memory leak, but the memory usage as detailed above is not terrible.

Also, is there a way to setup a scheduled reboot or is there a way that I can telnet into the system via a script activated via a CRON job?

ndanger69,

 

Did this occur recently? May you revert to the previous firmware version and let us know of any changes.

Re: RAX80/EAX80 stops responding

This has been occurring for at least the last 3 - 4 firmware revisions so I doubt that rolling back is going to resolve this issue.

I too am running the latest firmware revision on the RAX80 (V1.0.3.102_1.0.48).  I can usually expect a complete crash and restart at least once a day.  There is something fundamentally wrong in the firmware that is causing this issue.  I too see entries like this in the logs after the crash:

Great that it is blocking the attack, but it would appear to me there is a buffer overflow problem somewhere in the firmware and it has been there through the last several firmware updates.  Netgear, it would be great if you provided some sort of tool/utility that we could help you solve this.  Similiar to the crash reports that Apple/Microsoft allow you to send.

Same problem with eax80 with rax200.
My eax80 freezes often (about 1-3 days).
Reboot is needed.

I thought it was just me!!! 

 

This has been happening to me to forever now. This router is always locking up and I constantly have to reset it.
