Product page

The TP-Link WR940N is identical to the TL-WR941ND (detachable) except that

the antennas are not detachable and the hardware version is different.

(N - fixed (integral) antennas, ND - removable antennas)

There is no WR941ND-equivalent for v4, yet.

  • 3x 5dBi Fixed Omni Directional Antenna
The only difference between v3 and v4 is a more economic board layout
in v4 (smaller, different power supply) and an incompatible bootloader
(both U-Boot-Mods). The major hardware components are identical.
