Hi,
I got 2 TPLink EAP225 v3 with OpenWrt 22.03.2 installed as access points.
When I enable 5G and 2.4G simultaneously my clients that are further away, rather tend to connect to very low 5G (6 Mbit/s) than medium 2.4G (54 Mbit/s) which makes wifi nearly unusable.
So I figured that I should enable "option cell_density '3'" (Very High) on 5G to force clients with weak signal to use 2.4G instead.
For some reasons that does not seem to work as I am still seeing clients with 6 Mbit/s with 5G
I even took the trouble to set up a Linux laptop, put wifi in monitor mode and capture the beacon frames: Lowest speed announced: 24 Mbit/s
I don't understand why clients can still connect with 6 Mbit/s ?
you can't manage which wlan client will use.
What you could do is - activity polling, disassociate on low ack,...
so they switch to 2.4 if signal/ack drops.
Check also these options:
uci set wireless.radio0.ieee80211k='1'
uci set wireless.radio0.rrm_neighbor_report='1'
uci set wireless.radio0.rrm_beacon_report='1'
uci set wireless.radio0.ieee80211v='1'
uci set wireless.radio0.wnm_sleep_mode='0'
uci set wireless.radio0.bss_transition='1'
uci set wireless.radio0.time_advertisement='2'
uci set wireless.radio0.time_zone='CETXXXXXXXXXXX'
What exactly do you mean with "you can't manage which wlan client will use"
I am trying to use the same SSID but with 5GHz and 2.4GHz enabled
Of course I cannot force a client to use one or the other but in my understanding I could disable slow speeds with 5 GHz (like the 6 MBit/s) So instead of decreasing speed a client should disconnect from 5G (because there is no 6 Mbit speed available) and instead switch to 2.4G because there is e.g. 54Mbit/s available
