and this may overload the 3.3V power supply of the board that the card is located on resulting in
voltage drop and reboot or excessive temperatures for the board.
For different versions of Atheros chipset there are different value range of ack-timeout property:
Chipset version
5ghz 5ghz-turbo 2ghz-b 2ghz-g
default max default max default max default max
5000 (5.2GHz only) 30 204 22 102 N/A N/A N/A N/A
5211 (802.11a/b) 30 409 22 204 109 409 N/A N/A
5212 (802.11a/b/g) 25 409 22 204 30 409 52 409
If the wireless interfaces are put in nstreme-dual-slave mode, all configuration will take place in
/interface wireless nstreme-dual submenu, described further on in this manual. In that case,
configuration made in this submenu will be partially ignored. WDS cannot be used together with
the Nstreme-dual.
Example
This example shows how configure a wireless client.
