    Mikrotik RB250GS – 5 Port Gigabit Switch

    This little Mikrotik has the same form factor as the 750/750G. It is a 5 porter that I was able to get your standard gigabit speeds through…nothing remarkable there. So why should I buy one? First, they are shipped to your door for around $40. Not a bad price for a small managed gig switch.…

    Ubiquiti 900Mhz Announced And Others

    My boy JJ tipped me off to this. It looks like UBNT has finally announced their 900Mhz Airmax line. They’ve got a locostation and a 120 degree sector to go along with it. Since this is MIMO, they are saying that you can get between 20Mb and 100Mb through these guys. I think most people…
