  • Manufacturer: Comfast / Shenzen Four Seas GlobalLink Natwork Technology Co., Ltd.
  • Model: Comfast CF-WR750AC
  • WiFi: 802.11 a/b/g/n/ac
  • Frequency: 2.4G (2.412-2.484), 5G (5.180-5.825) (Dual Band)
  • Speed: 750MBit/s (450MBit/s @ 5GHz, 300MBit/s @ 2.4GHt)
  • Transmit Power: ⇐100mW (20dBm)
  • Receiver sensitivity: -90dBm
  • Antennas: 2 x External, non-detachable, 5dBi +/- .5 dBi + 1 x internal
  • Ethernet: 1x 10/100MBit/s, no Switch IC
  • I/O: 1xWPS/Reset-Button, 3 LED (Power, LAN, WiFi)
  • CPU: 520MHz
  • RAM: 64MB
  • Flash: 8MB
  • Size: 95x57x24mm
  • Weight: 85g
  • Notes:
  • Internal Power supply for 100-240V~ 50/60Hz, 50mA
  • Official CE-Mark (at least printed on…)
  • Serial header already populated and fully silkscreened

  • CPU: Realtek RTL8881AN
    • Lexra RLX5281 MIPS based SoC
    • Up to 520MHz
    • Integrated 10/100 5-port-switch (only one port used)
    • embedded 8MByte RAM
    • PCI-E host (connected to secondary WiFi)
    • 1x USB OTF (not connected)
    • IEEE802.3az
    • IEEE802.11ac
    • embedded 5GHz (802.11a/n) PHY
    • up to 433MBit/s (?!)
    • 20/40/80MHz bandwidth
    • Not really much online
    • Released probaby 2015
    • Some work already done, but no real success info :/
    • 802.11ac support
    • Looks like there is a linux SDK available
    • Also used in D-Link DIR-806A
    • RealTek Bootloader
      • Serial Console (38400 8N1?)
      • TFTP-Support
      • Depending on fuses HTTP and DHCP
      • can dump current memory and flash
      • can boot tftp-binary in RAM
      • can write tftp-binary to flash
  • WiFi-Controller: Realtek RTL8192ER
    • IEEE 802.11a/b/g/n PHY
    • 802.11n Draft 2.0 OFDM (BPSK, QPSK, 16QAM, 64QAM, 256QAM)
    • 2 spatial streams (2T2R; 2x2MIMO)
    • 2.4GHz, 300Mbps @ 40MHz
    • Multi BSSID support ← <yay?
    • Watnu? 802.11a at 2.4GHz is bullshit. Probably this IC only handles 2.4G while the primary CPU is managing 5G * Board: R116R * RAM: M14D5121632A * DDR2 * 8Mx16Bitx4Bank → 512 MBit == 64MByte RAM! * Flash: 25L6406E * SPI * 64MBit == 8MByte Flash * OS: Custom Realtek OK, no OpenWRT/freifunk Gluon (yet?)
