Connecting to wifi network on Motorola MC3100

While attempting to connect a Motorola MC3100 to my wifi network, I was getting a popup message saying that I might not be able to connect due to regulatory issues. Looking into the logs, I found the following message.

"Country code not acquired yet"

I guessed some sort of country code has to be sent my the wifi access point for the device to work. So, I looked into hostapd configuration manual and found that in the 'IEEE 802.11 related configuration' section, we can set country codes. So, I changed the following variables:

country_code=<your country code>
ieee80211d=1

When I restarted the wifi hotspot, the device could connect to internet successfully.

Connecting to WPA networks

Wireless networks using WEP keys are not very secure. WPA keys should be preferred over WEP keys. To connect to a wireless network on linux, first store the passphrase in a configuration file with the following command:

wpa_passphrase "<your essid>" "<your passphrase>" > /etc/wpa_supplicant.conf

Set up WPA handshaking using

wpa_supplicant -Dwext -iwlan0 -B -c/etc/wpa_supplicant.conf

The option -Dwext specifies that generic linux wireless drivers should be used. The -B flag tells wpa_supplicant to work in the background. The -iwlan0 option specifies wlan0 as the interface for communication. Now set up dhcp client on wlan0 using

dhcpcd wlan0
