Overview: I live in an apartment, and I wish to use Cisco routers to run my network for career development. I plan to place a 40 thread server in the other bedroom because I can't run it in the same room as my current desktop because it would overload the circuit. As a result, I require a Cisco router running IOS (I want the CLI) that possesses wireless capabilities to allow my IoT devices and phones/laptops to connect to the internet. I also require another cisco router with wireless capabilities to act as a bridge to the network for the server. I will also use two cisco switches, but that is the easy part of the equation unless the routers I find also have switches inside.
Running cables isn't an option because I can't drill the walls, and I would then have to run the cables from one bedroom to the other, which is not ideal.
Problem: The problem I am finding is that there is extremely cheap cisco routing equipment on eBay, but I am unable to know if these products have the capabilities I require. Also, finding the wireless NIC card that can be inserted into these devices is not easy. Deciphering compatibility is another issue entirely.
Question: Can someone please assist me in picking my devices. I am looking to use pre-owned hardware due to cost.
ISP: Version Fios 1gb pipe.
