    clients that support the IEEE 802.11a/n standards. Stations and clients must utilize the same SSID and Security Password to associate while within range. The most suitable topology for this mode is to have one ENH202 as an AP and the second one as a Client-Bridge – when necessary a third Client-Bridge can be place within the directional antenna’s path.

  • Page 14: Client Bridge Mode

    Not every Access Point supports WDS in Access Point Mode. It is recommended to use ENH202 if you would like to utilize this functionality. 3.3 Client Bridge Mode In the Client Bridge Mode, the ENH202 functions like a wireless client, connecting to an Access Point wirelessly and enabling Internet connectivity wherever you want.

  • Page 15: Wds Bridge Mode

    3.4 WDS Bridge Mode In the WDS Bridge Mode, the ENH202 can wirelessly connect different local area networks by configuring each device’s MAC address and security settings. The WDS Bridge Mode can bridge up to four local wired networks together as one logical network. Every computer on this logical network can see each other, sharing files as if they are in the same location.

  • Page 16: Client Router Mode

    WDS Bridge Mode is unlike Access Point Mode. APs linked by WDS are using the same wireless channel, and connecting excessive numbers of APs on the same channel may result in lower throughput. Please be aware to avoid loop connections; otherwise enable the Spanning Tree Function.
