Routing Issues

Unfortunately, I suffered intermittent routing issues - other users have reported similar issues in this thread.

Thanks to wilderbeastie, there is a workaround detailed here:

Option One

1. Enable telnet access in the router.

http://192.168.0.1/setup.cgi?todo=debug

2. Login via telnet to 192.168.0.1 (via putty or the command line)

3. Run the following command: -

"echo 0 > /proc/sys/net/ipv4/neigh/nas0/ucast_solicit"

This setting doesn't survive a reboot so needs re-applying every time.

If you suffer loss of routing, this procedure also seems to restore it (i.e. you shouldn't need to reboot first).

Option Two

This is exactly the same fix as detailed in option one but the command is inside the following link - all you need to do is copy & paste (all one line) into your browser and enter the username and password: -

http://192.168.0.1/setup.cgi?todo=ping_test&c4_IPAddr=%26/bin/echo%200%20%3E/proc/sys/net/ipv4/neigh/nas0/ucast_solicit

Again, this fix doesn't survive a reboot.

Option Three

James from ADSL24 has patched the standard firmware to run the relevant commands on startup of the router.

The downloads are here.

This method will survive a reboot.
