TEW-637AP (Version 1.0R)

  • Don't throw away your existing wired or wireless router, upgrade it to high speed wireless n
  • No setup required-just plug it into your existing router
  • Enjoy up to 12x the speed and 4x the coverage of wireless g
  • Secure Wireless Protected Setup (WPS) at the touch of a button

How It Works

The TEW-637AP (Version 1.0R) has been discontinued.  It has been replaced by the TEW-637AP (Version v2.0R). For a list of discontinued products, click here.

The N300 Wireless Easy-N-Upgrader™upgrades your old, perfectly functioning router, to high speed wireless n. Enjoy up to 12 times the speed and 4 times the coverage of a wireless g network.

Eliminate wireless dead spots, seamlessly surf the Internet and help the environment by not throwing away your old router.

The compact 300Mbps Wireless Easy-N-UpgraderTM is designed around ease of use, performance and environmental friendliness. The latest in wireless encryption ensures wireless security. Advanced Multiple Input Multiple Output (MIMO) antenna technology eliminates wireless dead spots. Wireless Protected Setup (WPS) lets you integrate other WPS devices into your network quickly.

**Maximum wireless signal rates are referenced from IEEE 802.11 theoretical specifications. Actual data throughput and coverage will vary depending on interference, network traffic, building materials and other conditions.
