I know this post will not add anything, but I just want to show my support to you guys who are finding ways to allow users to have custom routers.

Great work there.

I am also a Huawei HG850a user here. I am really slowly getting ticked off by Unifi's own Router.

If you can get the Huawei HG850a to work with a custom router, (in my case, Netgear WNDR3700), I have to belanja you makan one day man..

LoL
