dude... just bought this tenda ac18... i came to a setting called a wisp mode.. none of the google results tell me what it is... well what is tenda wisp mode?
WISP mode is simply a wireless WAN mode where your wireless access point device acts like a router internally but uses the wireless signal from another router as it's WAN interface. Since it is using the wireless interface for both WAN interface to the Internet and WLAN interface internally, it cuts the wireless bandwidth in half. So if the originating router has 30Mbps bandwidth then you can get only maximum of 15Mbps of bandwidth out of it.
However, it is sometimes better to operate in this mode if your location is to the originating router is farther away and you have many devices to contend the connections to the originating router. With many devices in place, the switching between devices often degrades the router performance, this especially true from the latency point of view. If the latency is high between the client and the router, the effective bandwidth will be greatly impacted. it is often better to put in an aggregating device such as a WISP client router to reduce the number of devices on to the originating router. Yes, bandwidth is cut in half but latency can be greatly reduced because now you only have one device connected to the originating router, thus makes the effective bandwidth much better.
Now with many WiFi hotspots in many urban areas (e.g. Xfinity/Hotel Wifi), if you want to use a Wifi hotspot with many devices, it is often better to use in WISP mode than in the repeater mode.

WISP stands for Wireless Internet Service Provider.
WISP router mode is simply a mode where your wireless adapter acts as both client and WAN port. In another words, you get to connect to another wireless network, use only one IP address they assign to you (and route internet (or whatever) to it), and route traffic to your local (home/private) network - NAT.
WISP is simply a wireless WAN port on your router.
