I want to buy a switch, from 8 to maximum 20 ports, fanless, with PoE, and one usable SFP, to install OpenWRT on it.
At work, I've found some Dlink DGS-1210-10P, but the revision is F3. The firmware is too new and Dlink support confirm it : it's not possible to revert the firmware on a openwrt supported version to be able to flash.
What's the best choice (typically well supported, install process could be less easy) ?
