networking

I need to bring internet access the street and am currently using a router running openwrt connected to my network access the street. I am thinking about getting a second router or outside ap to create a dedicated network for bringing internet across.

Is there a "best practice" to do this? Currently there is a high latency and it is unstable to to the limited range of my main network. I want to have a dedicated network to bridge the connections that only has one device connected. Is there a setup that works best for that?

Edit: I did it and it works OK. It really depends on how much interference there is. My connection is high latency but decent most of the time. The problem is that around dinner time it gets very slow and cuts out a bit which I assume is due to interference. It worked the way I needed it to but I think I'll just get a dedicated line for 30 USD a month (200mb/s bring your own hardware)
