1. Introduction
1.1. Summary
ESR7750 is a Dual Band Concurrent
Wireless 11N Broadband Router with dual
CPU that offers user unprecedented network
performance. WMM support boosts streaming
and multimedia intensive services. It supports
2.4Ghz band under 802.11 b/g/n mode while
providing 5Ghz band to guarantee an
interference-free network access.
Multiple SSID provides advance users to manage multiple users of various needs.
