Wireless Network Extenders

[Montjuic]

I have an ISP provider that insisted on a Fiberoptic conversion (from DSL) and ever since they "upgraded", I can't get to the Internet from my office (the garage), which is about 1000 ft and four brick walls away.
I tried installing a Netgear EX7000 wireless signal extender and set it up as an Access Point. This unit is dual band, but I noticed that my computer can see the Ex 2G and 5G networks that I created only when inside the house, but only the 5G when outside in the garage, so when I connect to the 5G from the garage, I can't get to the internet.
I can only get internet via the original base router or the 2.4G on the EX7000, which are only available inside the house.
I found out that the base router from the phone company is only 2.4G, not 5G, so a more powerful EX would not solve the problem because those also require 5G on the base/main router for the distant signal to work, right?
I called my phone company (ISP provider) and they recommended a "Video Bridge" that they say will "convert" their router from 2.4G to 5G, which then will allow the EX7000 5G Network I created to see the Internet and then I should be able to get Internet from the garage through that EX7000 5G Network.
Is this the right way to solve this problem?
I didn't know Video Bridge could work as a 2.4G to 5G band converter.

Connecting 1000 ft and 4 Brick walls needs an outside Antennae looking eye to eye.

Or lay a cable to somewhere in between and connect there a Good Wireless Router configured as an Access Point.

Even though you don't have a 5GHz network coming from the ISP's router, I don't see why you can't use the 5GHz band to bridge the connection across the 2.4GHz network. In the User Manual, under Section 4 there is a Static IP setup guide. Following that guide, copy the 2.4GHz settings but change the 5GHz IP address to a higher number and see if that will bridge the 2 wireless networks.

For example:

2.4GHz settings:

IP Address = 192.168.1.86
IP Subnet Mask = 255.255.255.0
Gateway IP Address = 192.168.1.254
Primary DNS Address = 192.168.1.254

5GHz settings (all fields should be blank to start):

IP Address = 192.168.1.186 (set this to higher number)
IP Subnet Mask = same as 2.4GHz
Gateway IP Address = same as 2.4GHz
Primary IP Address = same as 2.4GHz

If that doesn't work, then change the 5GHz Gateway to match the 2.4GHz IP address (eg, 192.168.1.86).

If you still don't get internet on the 5GHz band, then you will need another solution such as the Video Bridge or a wired Access Point.
