So far, it's been doing its job decently (good coverage in my whole apartment). However, many multiplayer games are blocked on its firewall, and port forwarding is hard to impossible on this POS. It has a really counter-intuitive user interface, and it just doesn't work.
I will keep on using this router, because I also have access to neighbours' Wi-Fi for multiplayer games, but if I were you, I would avoid Serioux routers. In fact, I think it's a Romanian product, so chances are you won't even see any.
