I am working on helping my church consolidate from using two internet connections with two modem/routers to one. The current setup is office computers wired and wireless on one router. Unsecure Wifi on the other router with two wireless access points (which are old wifi routers) that someone previously set up.
What is the best way to share one internet connections and keep the networks separate. I've read tons of how-tos and the negative effects of double NATs. I read about VLANs.
The local tech company quoted just using a "commercial grade" router at a price of $250. Would he just use the guest network? Not sure how they would keep the unsecure wifi separate.
I was planning on a managed switch and a similar router.
Your help is appreciated.
