How to connect lan + wifi network?

Question

WiFi

Good day everyone!
A question. Available:

• router Router 1 Mikrotik RB2011iL-IN ( link to DNS ) without USB ports
  
• router 2 with connected USB modem
  
• 6 pcs
  
• network storage
  

Is it possible to connect router 2 to the first one so that the internet connection is only wired?

Answer 1

Connect the WAN of the first to the LAN of the second. At the same time, on the first type of connection via wan - dhcp. Also, in the dhcp settings of both, you need to give different subnets. For example, the first has 192.168.88.1-192.168.88.254, the second has 192.168.1.1-192.168.1.254.
