Power supply5 V / 2.5 A

The Linksys WRT55AG router has a Broadcom BCM4702 @ 125 MHz processor. You cannot expand the router's memory (32 MB). When choosing a router, it is important to consider the RAM specifications. A larger flash memory allows for more space to store configuration backups. Linksys often releases firmware updates. They improve the router's features, security, and bugs. They also add new features. Using a custom OS on a router has benefits. But, it also has risks. The 5 V / 2.5 A PSU provides power to the router. If it breaks, you can replace it with a new one.

The router supports many networking standards. It ensures compatibility with different devices and systems. The IPv4 is the fourth iteration of the Internet Protocol (IP). It is the most widely used version of IP on the internet today. The WAN port on the WRT55AG router is a Fast Ethernet port, not a Gigabit Ethernet.

This router has 2 x 4 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 5 GHz band is less crowded. This leads to less interference and a clearer wireless signal. The WRT55AG router is 5 GHz capable.

If you have a small network with older devices and basic internet needs, an 802.11g router may still be adequate. 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.


USB portsno
Print serverno
File serverno

The WRT55AG router doesn't have file-server or print-server functionality.

Changing the password often is a good security practice. It protects your network and devices from unauthorized access. Changing the default password improves your router's security. It reduces the risk of unauthorized individuals controlling your network.
