EnGenius ESR300H Review

Aside from loading alternative firmware (DD-WRT or Tomato, for instance), the easiest way to upgrade a router’s performance is to replace its antennas. That’s impossible with most of the routers we see these days, because manufacturers are using either nonremovable antennas or they’re putting the antennas inside the enclosure. So we were intrigued to see that EnGenius put upgradeable antennas on its extremely inexpensive ESR300H; this router boasts a street price of less than $45.

As you’ve probably guessed, you’ll give up more than a few features in exchange for that low price tag. This is a single-band router with only a 2.4GHz radio, so we wouldn’t recommend it for deployment in an environment crowded with other wireless routers operating on the same frequency band. The ESR300H also lacks a USB port, so you won’t be able to share a printer or storage device over the network. But the feature you’ll miss the most is a gigabit Ethernet switch—the switch on this router is limited to 100Mb/s. If you move a lot of large files around your network using wired connections, you’ll find this router to be agonizingly slow.
