Hello community,
New adopter of a wrt32x and not a specialist in Wifi configuration.
Some days of testing but if some one can help...
My first problem was to activate more vlans on ethernet switch. Solved 
only manual update of files works to add vlans. Luci web interface doesn't work : {Network/Switch/Add button} doesn't provide a new line.
Then Wifi : Don't really understand why i have 3 devices: 802.11nac, 802.11bgn, 802.11bgnac.
I tried different configurations but i cannot find optimum one.
How mimo is working in this config?
Should i activate the 3 devices? only 1? 1 for 5ghz, 1 for 2ghz, 1 with both to support old and new clients?
When 2 devices bandwidth divide by 100 when load testing.
Any tips ?
Thanks in advance.
