Hi, I have to help my client they already bought 3 routers for 3 buildings. WAN connection is 4331 and other building connecting to it are 4221. But as 4331 only has 2 ports. Should I add module for more ports or replace 4331 with 4431? And do I have to buy license for 1GB connection to buildings?
Like WAN connection to 4331 is about 500MB and this connects to other buildings with fiber to 4221. Do i still need to buy performance license to get 1GB connection to each building?
Thanks for your help.
