Hi Ilario,
my actual Configuration is: OpenWrt 190704 (on ex6150v2) and snapshot
(ex6120/30) with libremesh 20.09
lime community with:
[...]
config lime 'wifi'
option htmode_5ghz 'VHT80'
option htmode_2ghz 'HT40'
option distance '100'
[...]
and lime-node with:
[...]
config lime 'wifi'
config wifi 'radio0' # 5GHz
list modes 'ap'
list modes 'ieee80211s'
config wifi 'radio1'
list modes 'ap'
list modes 'apname'
[...]
I use es6120/30 as Mesh-Nodes -> No use of the LANPort.
And an ex6150v2 as Connection to the internet (1GBit Lan-Port).
When I check the Lime-App (-> Metriken) I got an speed of max 60MBits. in
luci I see connection Speeds between 150 - 866 MBits RX/TX speed.
When I use an Internet connection Speedcheck modei got download between 1
(yes 1 - very strange) to 40 MBit and upload 15 - 40 MBit.
As you mentioned I will try to use the 5Ghz part only as mesh - and report
back ;-)
For your understanding: My Intention was to use AP on both - faster
Connection for 5Ghz able devices (IPad, iPhone) and 2 GHz for the older
ones... 2Ghz also as apname.
In my personal opinion the whole speed thing could be a showstopper (for
eg. lime)... but if solved the solution for many cheap meshes!
Regards,
Andy

I have a test-network running with a bunch of
ac/an Adapters.
I got connections up to 866MBits between the adapters (5Ghz mesh) but
even with this fast connection I only got 40Mbit up/down Speed in
direction to the internet.
Only on the one Adapter connected directly to the Internet i got the
full speed (250/40).
I also played around with distance parameters with no measurable impact.
Are there other possibilities to speed up the mesh?
That's a superinteresting topic, but I never tested it.
Which device is the AC one? Are them the "ex6120 and ex6130 Extender"
you mentioned in the other email?
I have no idea of how well the 802.11s mesh works with MediaTek. The
only thing I know about MediaTek is that you could have problem when
meshing over ethernet cable [1].
Maybe try changing the htmode (the wifi channel width [2]) to HT40 for
2.4 GHz and VHT40/VHT80 (which should work only for AC routers) for 5 GHz.
This could as well degrade performances rather than improve them [2] but
it's worth a try.
Due to a bug, this does not work when using LibreMesh based on OpenWrt
18.06 [3] but this should be ok for you on snapshot.
In /etc/config/lime-node
config lime wifi
option htmode_2ghz 'HT40'
option htmode_5ghz 'VHT40'
and then lime-config and reboot.
Another thing I always wondered but I never actually tested is how much
does impact to have one or two AP interfaces [4] (as compared to having
just 802.11s mesh), do you think you can test it?
For doing this, simply define the modes list with just the mesh.
In /etc/config/lime-node
config lime wifi
list modes 'ieee80211s'
and then lime-config and reboot.
Please let us know!
Thanks for experimenting <3
Ciao,
Ilario
