Summary: Just revisiting to see what others comments have been. Revise my review to one of the worst routers I ever regretted buying. All 3 units now dropping out the ADSL. Port forwarding to support Voip does not work. ICMP forwarding still not fixed since firmware update. Wireless range is worse than old 802.11G router that it replaced. Billion Tech support just deny issues, wont test for the problems in their own labs and ignore me.
Summary: 2 out of the 3 that I purchased loose internet connectivity on a daily basis. The 1 that seems to work reliably is within 100m or the exchange. Also, the ICMP forwarding does NOT work in the port forwarding options.
Summary: 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.
Cons: Everything. The awful method of saving changes (save, save again, then restart... for EVERY PAGE!).
