I have two Zyxel Prestige 660 HW T1 routers which are extremely unstable. Both routers will drop the DSL/internet signal and reboot at random. This problem is occuring with increasing frequency and it is extremely frustrating! I have tried various things including updating the firmware using the latest version from Zyxel. Before I dispose of both routers and buy something new, I would like to try if possible to load a third party firmware to see if this helps. I can't find any recommendations regarding this particular model router and I wonder if anybody has any experience with this particular Zyxel router?
I am not concerned if I brick either Zyxel as they are almost useless. I would even be willing to donate one of the units to somebody who might be willing to experiment.
