Answer:
Via the IP Address or Wired Connection
Step-by-step explanation:
When you want to connect to a router, there are most commonly two options to connect. You can do one of the following:
A)
1- Connect to the wireless network or wired network.
2- Navigate to the admin portal via the IP address (this is usually documented by the company, and if not, it is possible to use something such as NMap to scan the network to find the routers IP. But most of the time it is something similar to 192.168.x.x or 10.10.x.x)
3- Login to the admin portal and troubleshoot from there.
OR
B)
1- Plug an ethernet cable into the router to allow a direct connection to the router
2- Navigate to the admin portal via IP again, or use a tool such as PuTTY to remote into the router, depending on the type. For instance if it is a PFSense firewall/router, you can SSH into the router using PuTTY.
Hope this helps!
