IW - Wireless network CLI

The iw command is the new CLI interface to Linux kernel wireless drivers. It was written with the intent to eventually replace iwconfig, and as so should be adopted soon. There are only two documents describing it’s features, the man page, the kernel wiki page, and the cheatsheet for moving from iwconfig to it. Just as the linux kernel will perpetually be in a process of development, so will the iw command. Features for this command will be created on a as needed basis. Documentation for these features will arise much afterwards.

Cheatsheet

Below is a cheatsheet providing commonly used commands for iw.

1. Set up a new monitor mode – iw dev $DEVICE interface add $MON_DEVICE type monitor flags $FLAGS
2. Set regulatory domain – iw dev $DEVICE reg set XX
3. Delete Interface – iw dev wlan0mon del
4. Power save – iw dev $DEVICE set power_save on
5. Set TX power – iw dev $DEVICE set txpower <auto|fixed|limit> [<tx power in mBm>]
6. Station statistics – iw dev $DEVICE station dump
7. Stats against peer – iw dev $DEVICE station get $PEER
8. Link status – iw dev $DEVICE link
9. Set Channel – iw dev $DEVICE switch $CHANNEL
10. Scan for devices – iw dev $DEVICE scan
11. Enable monitor mode on existing device – iw dev $DEVICE set type monitor
12. Configure monitor flag – iw dev $DEVICE set monitor $FLAG
13. Set ack timeout according to distance – iw phy $PHYNAME set distance <auto|$DISTANCE>
14. Set antenna bitmap – iw phy $PHYNAME antenna $BITMAP

Monitor flags
