OK, I did it. USB does not work when uploading a new image.

One more tv-box, HK1 Rbox. It hase an HK2735M chip Almost all things works, but WiFi can't connect to 5G, while 2.4 work fine. It see 5G AP, but connection fail. @transpeed-8k618-t:~$ dmesg | grep brcmfmac [ 7.019181] brcmfmac: brcmf_fw_alloc_request: using brcm/brcmfmac4335-sdio for chip BCM4335/1 [ 7.019857] usbcore: registered new interface driver brcmfmac [ 7.094608] brcmfmac mmc2:0001:1: Direct firmware load for brcm/brcmfmac4335-sdio.clm_blob failed with error -2 [ 7.094631] brcmfmac mmc2:0001:1: Falling back to sysfs fallback for: brcm/brcmfmac4335-sdio.clm_blob [ 9.242828] brcmfmac: brcmf_c_process_clm_blob: no clm_blob available (err=-2), device may have limited channels available [ 9.242856] brcmfmac: brcmf_c_process_txcap_blob: no txcap_blob available (err=-2) [ 9.243349] brcmfmac: brcmf_c_preinit_dcmds: Firmware: BCM4335/1 wl0: Mar 24 2013 20:36:01 version 6.30.171.24.20 (B0 Station/P2P) PS: Okay, that's fixed. I just changed the channel on the router, it works with channel less than 40

Thanks a lot, now the wifi is working. I have this strange clone in my hands, it is marked as Vontar H618, but the Vontar image on it cannot be written to eMMC. In the case of the Transpeed image, everything is working correctly.

I've used this patch, but it doesn't work for my case. Is it possible to change something for this chip? klipperr@transpeed-8k618-t:~$ dmesg | grep brcmf [ 9.510496] brcmfmac: brcmf_fw_alloc_request: Unknown chip BCM43342/1 [ 10.520808] brcmfmac: brcmf_sdio_htclk: HT Avail timeout (1000000): clkctl 0x50 [ 10.545676] brcmfmac: brcmf_ops_sdio_probe: F2 error, probe failed -19...

What about the speed? iperf3 report about 55-58 Mbits/sec

This is 88XXAU in the config. Yes, this driver allows you to see the device as a network device, the adapter gets a new interface name wlx<macaddress>, but it cannot connect to the network and does not receive a list of available networks.

What should I do for rtl8812 to work?

Thank you, I tried. But this is not my level, it is too difficult for me. I'll probably wait for your next release.

Is it possible to use usb-wifi on an 8812au chip? I tried installing the driver, but it doesn't work: klipper@transpeed-8k618-t:~$ sudo dkms status [sudo] password for klipper: rtl8812au/5.13.6-23, 6.12.11-edge-sunxi64, aarch64: installed klipper@transpeed-8k618-t:~$ sudo modprobe --force 8812au modprobe: ERROR: could not insert '8812au': Exec format error I also have a Mediatek mt7601u from the recommended list, but it doesn't work either.
