If the 11n_disable option is not recognized, try 11n_disable50 instead. This unloads the iwlagn kernel module, then re-enables it without wireless-N. (For example if your access point says wireless-G somewhere on it.) If you run dmesg | grep iwlagn to search the kernel’s log for messages from the card’s driver, you may see the message iwlagn: Microcode SW error detected., followed by several lines of debug data.ĭisabling wireless-N will prevent this error from occurring. This change is not required if you know you will only be using wireless access points that do not support wireless-N. It seems as though Intel and/or the kernel developers are still working on wireless-N support for this device.
(Use sudo.) Credit to this poster for discovering this fix! You will need root access to edit this file. On line 39, change “power on” to “power off”. You can permanently disable power management by editing the file To turn power management off manually, doĪnd type in your password.

#Intel centrino wireless n 1030 driver not working download#
The device connects to the network, but rarely exceeds a download rate of over 1 kB/s.įirst, power management needs to be disabled. With power management and wireless-N enabled on my card, I get very poor connectivity. These fixes may be applicable to other wireless devices that use the iwlagn driver. These changes were necessary under Linux 3.0.0-14-generic they may not be required on newer versions. I got this information from other posts scattered across the Internet, but I thought I would write them up here to save people some trouble. This wireless card came in my new Dell Inspiron 14z laptop, but I had to make a few changes for it to work correctly under Linux.
