I was wondering if the Belkin F7D3302 was actually a supported router in LEDE?
For some reason all the Belkin F7D routers have been removed from the OpenWrt/lede builds,even though the Lede /OpenWrt websites-wikis expressly say these routers are supported.
The existing information implies basic support was added into OpenWrt at some point, but I don't see any images available. Usually, the OpenWrt wiki links to those.
There's talk of a custom OpenWrt tree but last commit to that tree is from 2014. That's from before the Chaos Calmer release.
It wouldn't be the first image to be missing; however, noone except the owner of that domain can tell you where these builds originate from, and it's not a mere mirror of the official images. The official 15.05.1 OpenWrt repo does not list any Belkin images either - nor does their trunk repository, for that matter. So again, that heavily points towards a custom tree.
I understand you'd like your hardware to be supported out of the box (we all do, after all), but since you seem so convinced there is official support, I have fired up my buildroot, looked through the available brcm47xx/mips74k targets, but no Belkin there unfortunately. Grepping the git tree doesn't make them show up either.
