My last post was about draft n dual band with normal channel (6) and frequency (2,437 Ghz) but for what it’s worth – dual band needs media being transported through the second frequency band (first one is for clients only, but the streaming box for the tv will be the other one).
On Debian Lenny, make sure you’ll have the latest kernel installed, then sort some prerequisites:
$ sudo apt-get install wireless-tools wpasupplicant
in order to use all wireless extensions. Then apply the same routine for ralink’s driver – change wpasupplicant support in os/linux/config.mk, type make and make install as root but then do not reboot yet.
# vim /etc/Wireless/RT2860STA/RT2860STA.dat
and change channel to 36 (5.18 Ghz)
Channel=36
Afterwards, same procedure as usual – define the ra0 interface.
# vim /etc/network/interfaces
auto ra0
iface ra0 inet dhcp
wpa-psk fjskjfsjfskl
wpa-ssid öfsdkföjsdkdf
Reboot and then check with ifconfig. If it did not work out, try the following steps.
If you are not sure about the frequency and channel, scan for it (therefore we needed wireless-tools):
# iwlist ra0 scan
ra0 Scan completed :
Cell 01 - Address: XX:XX:XX:XX:XX:XX
Protocol:802.11a/n

Frequency:5.18 GHz (Channel 36)

Check back in your RT2860STA.dat if it’s correct and if not change and reboot then.
To check on your actual frequency, do this:
# iwconfig ra0
ra0 Ralink STA ESSID:"xxxxxxx" Nickname:"RT2860STA"

That’s all – traffic between the 2 frequency bands is routed through the draft-n wireless router and our wireless cloud is ready to work 🙂
