If you plan to move or travel a lot and need to take your router with you, the size is important. It needs to be small to be easy to carry. The weight of router is not typically a critical factor for most home or office setups.

The Atheros AR7240 @ 400 MHz CPU provides processing power. It handles tasks and services within the WRT120N router. 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. The firmware upgrade process may vary depending on the router model. However, it often involves accessing the router's web-based administration interface. The Linksys packages the WRT120N router with 12 V / 1 A PSU.

A well-positioned antenna can reduce interference and signal weakening. This leads to a more reliable connection. Many IoT devices, smart home devices, and older Wi-Fi devices mainly use the 2.4 GHz band. This is a Wi-Fi 4 router, with slower data transfer speeds. This can result in slower downloads, video buffering, and reduced performance. The top speed, 150 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. The introduction of WPA2 (Wi-Fi Protected Access 2) improved upon WEP. It provides stronger security.

Connectivity

The WRT120N router doesn't have file-server or print-server functionality.

Administration

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.

Pros and Cons

Every router, including this Linksys one, has its good sides and not-so-good sides. Let's take a closer look at both to get a full understanding of what this router can do. We'll talk about what it does well and also where it could use some improvements. Just remember, this is just what I think, and you might see things differently.

Pros

  • lightweight

Cons

  • insufficient flash
  • lack of Gigabit LAN
  • Non-gigabit WAN port
  • missing Wi-Fi 6 support
  • lacks Wi-Fi 5 compatibility
  • reduced Wi-Fi bandwidth
  • incompatible with WPA3
  • missing WPS support
  • no USB connectivity
