Belkin F9K1115 v2 (AC 1750 DB)
Dual-Band AC+ Gigabit router
Supported Versions
The F9K1119v1 has the same FCC ID as the F9K1115v2 (K7SF9K1115V2).
F9K1119v1 (AC1600)
19.07 factory.bin installs on the F9K1119v1 (tested through 19.07.10). However, the ath79 builds fail both via GUI and in recovery mode - tested 21.02 and 22.03, both sysupgrade and factory.bin (after OEM reversion). This issue does not apply to the F9K1115v2 [?].
NOTE: the F9K1119v2 is a Realtek SoC and thus not OpenWRT compatible.
Hardware Highlights
Installation
Use the stock GUI to upload and install OpenWrt using the factory.bin image.
OEM Reversion
See recovery.
Recovery
NOTE: A WAN input might be required to access the OEM GUI.
- Either:
- Plug in power, hold reset as soon as the WPS light comes on until the main LED continuously flashes yellow.
- If running, hold reset until the main LED is flashing blue, release until it briefly flashes yellow, then hold reset until it continuously flashes yellow.
- Open 192.168.2.1 in a web browser to access recovery (named “Bootloader Upgrade UI”)
- Load the OEM firmware (OpenWRT 19.07 factory.bin does not work for F9K1119v1).
At this point, an OpenWRT factory.bin image can be loaded if desired (use 19.07 for F9K1119v1).

USB
USB 3.0 seems to work fine since CHAOS CALMER (15.05, r46767):

802.11ac 5GHz WiFi channels
Edit: Recent versions of OpenWrt, >18.06.0, have this problem resolved, I've never encountered it using 80MHz bandwidth and channel 100.
With 80MHz Bandwidth all the channel in between the ones below fall back to the previous freq. Beware some of the channels don't work at all,in my tests with 3 different devices I only managed to make channel 36 and 44 work with 15.05.
Channels:
