I have a Vodafone supplied EchoLife HG556a and every few days devices will stop being able to use DNS.
The connection stays up, I can browse to sites if I use their IP address, but no name resolution at all. Once I reboot the device, DNS starts working again. I have a static IP.
Software version is V100R001C12B029, the modem came with a Sure Signal box (which I'm using at another location).
