I recently got the free G1100 router with my upgrade to 150Mbps. I wired ethernet from the ONT to my own Asus router, so I don't actually need it for the speed, but I would like to use it as MoCA/ethernet/WiF bridge in a room that has otherwise weak WiFi signal and would be a pain to bring ethernet to. The router arrived with a 1.04.00.10 firmware, which doesn't have any option to update it in the UI.
I really don't want to interrupt the internet use in the house to wait for the gateway to get activated as a primary router. For now I set it up behind my Asus router in a DMZ, but this does not seem to be enough for it to pick up the firmware upgrade, even though it is definitely online and I can browse the internet connected to it.
I have to say I am impressed in a BAD way by the WiFi performance of the Quantum Gateway with the current firmware version. My other routers get double the throughput going 50' through multiple stucco walls that the new router does from 3 feet away in the same room. A lot of the settings are pretty buggy, for example, when I set it up as a bridge before just putting it behind my router to try to get the update, I had to add a route for anything connected to the G1100 through WiFi to get to the internet (ethernet ports worked without this route though). Also it wouldn't allow this route to be entered with a 0.0.0.0 netmask (aka default gateway) but a 1.0.0.0 mask was treated as 0.0.0.0. Lots of other flakiness seen, which I'm hoping a new firmware would fix.
