After the purchase, the first thing I did was ate the firmware to the latest at the moment 1.1.0.50. The Internet worked without questions, it was not necessary to set up anything special. I connected an old Canon MF3110 MFP to the router, installed Netgirov's ReadySHARE USB Printer (USB Control Center) software, everything worked, something was printed and even scanned. But the next day after installing the program on another computer, the USB port fell off the router (it stopped responding even to a USB flash drive). Problems arose either when installing the USB Control Center, or when pressing the "scan" button in the program, or simply by themselves somewhere in a day. Only restarting the router helped. I experimented with a flash drive - it worked quietly for a couple of days. That is, the problem was with the MFP. I tried network printing to the raw 9100 port (as on the old router) to do without the ReadySHARE software at all, but this trick did not work with the R6220. Resetting to factory settings did not help. As a result, I rolled back to the old firmware 1.1.0.34, and, lo and behold, everything has been working without any failures for more than two weeks. So the cant is either in the new firmware 1.1.0.50, or in its compatibility with the USB Control Center v1.36. To recommend this device or not is an interesting question. If you are an ordinary user who just needs a "box for the Internet", then this option is quite suitable - in terms of the Internet and connecting computers / phones / tablets to the R6220 there are no complaints. Given the characteristics - cheap and cheerful. If you have a USB printer or MFP, then consider the above. If you are a happy owner of a printer / MFP with an ethernet or wi-fi connection, then everything should probably be fine (however, who knows). If you need a device for experimenting with alternative firmware, and at the same time you yourself are not going to participate in the development of these firmware, then everything is at your own peril and risk. Explore specialized forums - perhaps in the future there will be some options.
