communicate between two ISP's routers

I have network access with Comcast DSL and a Netgear router in my home shop then got fiber and a Calix router in my home. Is there a way that I can communicate to both and not interfere with the other? Hoping.

Just curious...any particular reason you pay for two ISP connections instead of one? How far apart are the two buildings?

Well it is a long story. I had a DSL account from Peak and CenturyLink disabled their ability to service my residence so I got CenturyLink for my landline and network (DSL) Recently Peak was offering fiber to the home so I got it for nostalgia and support of them since they started out as a university computer foundation. I probably could use DSL in both places but I still have a network cable to run and connect in order to get the Calix network connected from the house to my shop. As to how far, not far, probably 100 feet and I do have a switch. I was just curious on how to connect with software (probably due to the 192.168.0.0 NAT)

DSL isn't provided by Comcast as a "landline."

You are right and I don't know my 'C' providers. It was/is Century Link 

It really would be best for you to get an accurate handle on your two ISP connections. If anything, make a speed test on both routers, pick the one that provides the fastest bandwidth and just as importantly most reliable. Do not do the speed tests over WiFi, use an Ethernet cable, and plug it directly into each router. I'll suggest using:

Access both download and upload speeds, and latency. This gives you a baseline to work off of, and then take into consideration aspects like WiFi coverage range if that's an important issue for your household.

Once you've determined the best ISP for your household, cancel your account with the other one, and focus on setting up your chosen modem/router and your Netgear router to work together (i.e. it sounds like you want to consolidate two separate local networks to be one so set up your ISP-supplied modem/router and your Netgear router in bridge mode. Your current set up includes two modem/routers, the point being with two routers you also have two isolated from each other local networks to contend with, possibly three depending on how you've configured your Netgear router).

With only one local network all the devices (computers, laptops, mobile devices, NAS, printers, etc.) will be connecting to just one local network so file/printer sharing will be less contentious.

You might find this router setup guide to be helpful, if you need to optimize your household WiFi coverage. If you're relying more on physical Ethernet cabling, never mind.

svim, thank you I will probably do as you say in the future. I had the phone in my shop and thought it would be convenient network availability. I am using sneaker net but might set up a dmz in the interval to get some data across. It's not ideal and I'm planning to rectify it soon.
