Ok here's the setup:

 

  • Remote location visited every 3-6 weeks for a few days
  • Vodafone Huawei (556?) Router
  • DHCP devices (IP Camera, Raspberry Pi) accessed via port forwarding from Internet
When at the location the router works fine for both wired and wireless devices, laptops, phones etc. However, exactly 7 days after leaving the location, the router goes dark on the Internet side.

There are still connected devices (via wireless) on the local side, and ftp traffic still going from the devices, through router, to Internet sites.  However the router does not respond to any internet traffic whatsoever.

Any thoughts / suggestions / fellow sufferers / wizards out there?

Cheers,
G.

Unfortunately firmware version unknown at this point: I didn't think to record it last week and now it'sa little too far away.

You have remote access to any of the devices ? Log into the router from one of them and grab the version info.

Remote management is enabled by default on the 556a.
If you have the IP address(maybe ring the ISP and ask for it) you can access the web interface from any internet connection using the username & password support/support

Unfortunately all external access to the internal devices is via the router.  I've got the latest external facing IP but there's no response to ping (understandable), and port forwarding of 80/443 theoretically goes to the IP camera.  Telnet and SSH directly to the IP address also get no response.  It looks like the router has stuck its virtual fingers in its virtual ears.  

If all else fails I suspect I may have to schedule a regular (every 7 days?) reboot via a scripted telent session from the Pi (that's assuming there's a CLI I can get to on the router).  That'll have to wait until I can get back to the location (3 hour drive) in a few weeks.

that seems a spectacularly bad setup to be on by default...

Ok, how about this - anyone know of a DoS/buffer overflow trick for the router that would cause it to reboot - that'd do me!
[and before you get worried I'd be happy to give specifics to prove this is legit, not a Script Kiddie fishing expedition, and receive answer via message!]

Yup... ask someone at the other end to pull the power out.
