Situation: Previous company setup each building on their own ISP/Modem. They then used cisco routers to create a VPN connection over the internet from the looks of it to the other building. This from my deduction has caused quickbooks to freeze and work horribly when trying to access the central server in building 2 at the bottom.
Fix: What I want to do, correct me if this is the wrong way to go, is setup a wifi bridge by shooting a signal to each and connecting as so:
Is the going to be the correct way to go?
Also, what should I consider or look for when trying to determine hardware? My issue is they want this done ASAP and while I understand networking decently enough, I lack physical tools like ladders, drills, glue, ect... for doing serious professional mounting with polls like if I was going to mount a satellite dish. So I was wondering if maybe it would be enough to just mount or position the wifi bridge antennas in the comrooms high enough to shoot through the buildings roof and if that would be ok due to the short distant.
We ruled out running fiber or a CAT6 cable just due to all the concrete and hard labor that would be involved to properly run the line.
