Sommaire: The worst router I've ever owned. Billion obviously has no quality control. When I first tried to set it up it would wipe all my settings upon a reboot.... and you need to reboot to save any settings! Fortunately a firmware upgrade fixed that issue, but I can't believe they shipped a product that does that. Once I was able to save settings I manage to get the modem configured and working, but it was the most painful experience.
Contre: Everything. The awful method of saving changes (save, save again, then restart... for EVERY PAGE!).
