I have a Netgear R7800 with 22.3.3 and a few Asus Lyra as nodes (snapshot because it has DSA and it’s seems stable enough and didnt want to redo configs in the future). They are in a 802.11a mesh running batman-adv, with a few different ssids/vlans. I can’t express how stable and how non fuzzy this runs: it just works with zero problems whatsoever.
But I can’t for the love of god make MT7621(a) devices like my Xiaomi Mir3G and TP-Link Re-650v1, work in the same mesh as my R7800 and Lyra. The wireless mesh connection will show excellent connection. The Re-650v1 will even connect at 160mhz to my R7800 (but for some reason my R7800 doesnt work in AP mode with 160mhz, but for some reason it works in 802.11s mode). I can get an IP from the R7800 gateway, if I connect via a MT7621 node (both wireless and wired) albeit it’s kinda “shaky”, but that’s about it. I am maybe able to load a simple webpage as google.com if I am lucky. Once I even managed to initiate speedtest.com and it showed 0.2mbs. You get the picture.
It goes also the same the other way: If I am connected to my R7800 or Lyra I can just about access Luci on my MT7621 devices..but it’s slow and it’ll hang up etc.
But if I create a mesh only with Mir3G and RE-650v1, then they work perfectly together. I don’t care that much for the Mir3G (although it’s actually usable now compared to a few years ago) but the RE-650 would make a great mesh node, but it seems it’s not meant to be.
Does anyone know what’s the root cause of this incompaitbility?
