Hello there!
I need to restrict one wifi device used as a client to 5GHz mode only. This is my config:
#########################################
config wifi-device radio1
option type mac80211
option channel 44
option hwmode 11na
option path 'platform/ehci-platform/usb1/1-1/1-1:1.0'
list ht_capab GF
list ht_capab SHORT-GI-20
list ht_capab SHORT-GI-40
list ht_capab TX-STBC
list ht_capab RX-STBC12
option htmode HT40+
config wifi-iface
option device radio1
option network wan
option mode sta
option ssid 'uplink'
option encryption psk2+aes
option key 'xxxxxxxxxxxxxxxxxxxxxx'
#########################################
Even though I've specified hwmode as 11na, the device scans and sees also 2.4GHz networks.
Since the AP on the other side is configured with the same SSID and password on both bands
my client establishes a connection on 2.4GHz when the 5GHz link fails.
So, am I doing something wrong or is the hwmode setting simply useless?
What is the proper way to limit my device (RT5572 dual band USB 802.11abgn) to 5GHz only?
