Hi Experts, I write about this argument because our WRP400s continue to freeze.
We are a Internet and Telephony Service Provider and we have chosen Cisco-Linksys CPEs imagining to find the same stability of well know Cisco equipments.
Unfortunately, we find that the Linksys devices are not Cisco devices.
We use WRP400s since version firmware 1.00.04c.
Over the years we have tested this list of firmwares:
1.00.04c
1.00.06
1.01.00
1.01.01
2.00.05
2.00.11
2.00.16
2.00.20
2.00.21
2.00.26 (actually used)
We can say that there have been improvements but we are far from a stable device.
The reason of this post is a common block presents in latest version 1 and all veriosion 2 of the firmware.
After several days of normal activity the voice module of WRP400 freezes.
This is a description of WRP400 during this block:
- PING is OK
- remote access to the router web menu is OK
- Internet surfing from LAN is OK
- phone line is KO
- remote access to the voice web module is KO
- every operations from the router web menu are ineffective (change LAN IP, diagnostic PING or diagnostic LAN search, reboot button, reboot url of version 2.00.26, ecc)
The only procedure to restore normal working is power off and on the device.
Now I'm trying to reproduce the cause of these stops without succes.
I think that the problem is in the router module and consequently blocks the voice module.
I have a feeling that the DHCP module is causing the problem (for now there are only hypotheses).
I think in a memory leak and so the first question is:
Is there a tool to monitor memory and CPU usage?
Can you find a workaround? e.g. a configurable hardware reboot in cron?
I'll update this post with new elements as soon as possible.
Thanks in advance.
