This setting communicates to surrounding networks that this WiFi adapter is not tolerant of 40MHz channels in the 2. The default setting is for this to be turned off disabled , so that the adapter does not send this notification.

Use to avoid data collisions in a mixed CTS-to-self can be used to gain more throughput in an environment where clients are in close proximity and can hear each other. CTS-to-self is not supported for When creating an administrator package, Power Management lets you select a balance between power consumption and WiFi adapter performance. NOTE : Power consumption savings vary based on infrastructure settings. Preamble Mode. Changes the preamble length setting received by the access point during an initial connection.

Always use Auto Tx Preamble to provide optimal network throughput. Auto Tx Preamble allows automatic preamble detection. If supported, short preamble should be used. If not, use Long Tx Preamble. This setting lets you define how aggressively a wireless client roams to improve connection to an access point. Click Use default value to balance between not roaming and performance or select a value from the list.

Only significant link quality degradation causes it to roam to another access point. Enables you to expand the number of coverage areas or confine a coverage area. Reduce the coverage area in high traffic areas to improve overall transmission quality and avoid congestion and interference with other devices. You may re-send via your profile. This isn't a question, it's a solution that worked for me so I thought I would post it pre-emptively!

Having just forced it to upgrade from Windows 7 to Windows 10, I noticed straight away that the wireless was not working maybe that's why I didn't ever see the Microsoft upgrade option. Nothing much seemed to happen, but on checking Device Manager, the system indicated that the driver is installed but "the device failed to start". I disabled the device, then enabled it - still nothing Anyway it rebooted, connected to my network and is running perfectly.

Not bad for an old Vista machine. Maybe the driver was installed all along and all I needed to do was reboot the machine in the first place. I don't know, drivers aren't really my thing! I thought I'd post this just in case there are other people with similar antique machines lying around.

I upgraded it from Windows 7 to Windows 10, and now the wireless does not work. I've tried the solution listed above, but it hasn't made a difference.

I realise that this adapter is now unsupported, but I wondered if you had any advice as to how to fix this issue, maybe a replacement driver or something? Intel does not provide drivers for this configuration, and we are not aware of possible workarounds. I'd like to let you know that workaround with powershell script works for windows 10 as decribed here:. It is good to know that this is working for you. Just keep in mind that Intel does not have support for this adapter and OS combination, so we cannot guarantee that this will work in every scenario.

No wifi after upgrading from Win 7 Ultimate to Win 10 and Device Manager displayed the following message in the Device Properties dialog box, on the General tab, in the Device Status text box: "This device cannot find enough free resources that it can use.

If you want to use this device, you will need to disable one of the other devices on this system. Code 12 ". The following actions rectified the problem and might be worth a try for other people. Reboot and Windows will automatically reinstall the Intel driver under the revised configuration and you should have wifi. I probably found the solution for the Wireless disconnect after waking up from sleep mode with the Intel ABG.

I simply disabled the "Computer can disable the device to save energy" option. The option can be found in the Network Adapter configuration at configure - Energy saving options. As I have a German OS, the english terms might be different, but you will get the respective options by its meaning I had the same problem. I know this is an older thread but thought I would put it out there for people to see.

This is an excellent technology to make the most of when you need t. Download Latest Version for Windows. Download Latest Version for Free. Net Speed Booster. Wireshark bit. Speedtest by Ookla.
