I couldn't find a lot of discussions around Linksys Velop. I've grown old of not having OpenWRT because I moved into a three story house 12 months ago, and I decided to try something main-stream.
The Specs between the Velop and Lyra look very similar. The Velop has 512MB RAM vs 256MB, 4GB Flash vs 128MB, Different Bluetooth chipset, I didn't see any CSR BT in the supported hardware database, but I don't use BT. The Velop also has ZigBee, which I don't use either.
In the past I was spoiled because I used a Merlin build for my Asus devices. I see I will need to dust off some cobwebs, and hope by brain hasn't turned into teflon when I'm trying to absorb how to embrace loading OpenWRT on the set of 3 - Linksys Velop WHW03v1 access points.
I'm a complete newbie, so I apologize in advance for all the taboo things I may have just done.
