I have this Pagex 150 Mbps usb wifi stick (RT5370) which failed to load on Solid 6141, but worked flawlessly on Freesat V8 Golden receiver. It turns out that the VID/PID info of wifi adapter is also important, not only the chipset. Finally, I had to update the 6141 with HD Box firmware, then the adapter was detected. So if you couldn't find the compatible adapter, then look for an alternative firmware, suited for your receiver.
