After over a month of using the "Bright Box 1R", here are my detailed findings:
~ It should be re-branded "sh*te box", just like the other 2 of their cheapo, generic, flaky, buggy routers.
~ Constant uPnP errors and disconnects from my Raspberry Pi 3 DLNA server, which was working flawlessly on my "DGTeam" DG834G V3 - rubbish Bright Box.
Mind you, what can one expect when one is handed a "free" ISP router? ISPs are in the game to maximise profits and supply you with internet, they are NOT proud manufacturers of highly optimised & tweaked performance routers, so is it any surprise that the built-down-to-a-price creaky boxes of junk don't perform as one would expect? If they can afford to give them away (and often replace them 4-5 times, or MORE) then they clearly aren't made OR tested that well.
Most of that is rhetoric, you all know that ISP routers are rubbish, but I just thought I'd make it known that yet another (not so)-"Bright Box" is out in the wild, and riddled with problems.
I am not a router expert, but I know when something that WAS right, suddenly isn't.
Cheerio, thanks for reading
