AC750 Wireless Range Extender

Product page

"2053500117" is silkscreened on the board in the FCC photos.

Hardware appears to be very similar to the Netgear EX6100.

Unit has internal power supply and plugs directly into mains power socket.

Stock firmware only functions as an extender and client bridge and does

not support access point mode.

Basic details

To get the unit open, remove the two screws at the top. Squeeze the case in the middle

of each side t help loosen the two clips that continue to hold it together.

It takes some force to separate the two halves, but be careful not to damage the short

the antenna cables when the case finally gives.

There is a ceramic heatsink on the CPU - you can remove this to inspect it by giving

it a twist. It will remain adhesive so can be re-attached when finished.

Reviews

Serial

Pinout

J1 is a serial header. Pin 1 is closest to the top

of the unit and pin 4 closest to the Ethernet port.

The pinout is as follows:

© 1 - Tx
© 2 - Rx
© 3 - Gnd
® 4 - Vcc

Connect with settings 57600 8N1. Signalling voltage is 3.3v.
