Hello

There is a local ISP in my area that provides internet through what I think is microwave connection.
They basically install an antenna on the roof of the building and wire a network cable from the roof to the apartment.
Available bundles are 2Mbps to 8Mbps. I am thinking of getting the 5Mbps 130G limit (I have no landline)

is this a common installation process?
if anyone has a similar connection, is it good?
does it cut off when there is bad weather?
I am currently subscribed with connect 2Mpbs (its slow and expensive). will the local ISP 5Mbps be much better?
if local isp you mean the cable guy then it is not microwave .. mostly some mikrotik or ubnt AP .. microwave is licensed
try getting ADSL in its place way better
If you call them and ask, they may give you a test line for a couple of days so you can check their 'promised' speeds and service. I tested out someone's 3mb service and over the course of 3 days, the best I got was 1.8mb and it was usually 1-1.2 mb so I didn't sign up. It couldn't hurt to try, and just be aware, these guys depend on line of sight, so you may lose connections in rainy, foggy or even dusty weather.
