That is indeed the 250 package...Alright, if you wanna copy our overpowered setup, you're going to need a Huawei b618-22d, and a Poynting xpol-6 antenna. For the antenna, you will need TS9 to SMA adapter, to plug into the router.
I am curious to know your signal stats, and to see what band you are on. Our tower is far away, like over a kilometre, and we very slowly adjust the antenna mounted on a pole to get the best direct line to that tower, which to be honest, I can't even see. We point to that far away tower, because it's a 2600TDD tower, which is faster, but you need to have a high gain antenna if you're far away from it, and just keep on trying to reposition it until you manage to find a decent signal, then fine tune it from there.
If there is no 2600 tower in your area, that's pretty unlucky, however, we've gotten as high as 30-50mbps on the 1800 band, and the upload is like 25mbps...The only thing is that the 1800 towers are often quite congested, so at most times of the day, you only get like...10-20mbps even if you're all kitted out. Still a hell of a lot better than the connection you have.
The above mentioned equipment isn't really THAT expensive, considering the improvement you will have. Got our b618 for a grand, and the antenna for a grand. Just have to shop around.
