The dimensions and design of a router can impact its cooling capabilities. Routers with larger dimensions may have more space for internal cooling mechanisms. If you plan to mount your router on a wall or ceiling, the weight can affect the mounting process. It also affects the type of mounting hardware needed.

This router has 3 x 3 dBi, RP-SMA antennas. Antennas are key parts of wireless routers. They send and receive radio signals to make wireless connections. This router is 2.4 GHz capable. The 2.4GHz band refers to the portion of the radio spectrum between 2.400 and 2.4835 gigahertz. The 802.11g or Wireless-G operates in the 2.4 GHz band. It provides faster data transfer at up to 54 Mbps. The top speed, 54 Mbps, is the highest data rate the router can reach. It's the theoretical limit in perfect conditions. WEP was the first Wi-Fi security protocol. But it is now seen as weak and easy to hack.

Connectivity

USB portsno
Print serverno
File serverno

The WRT54GX4 router doesn't have file-server or print-server functionality.
