Although configurable on most wireless devices, Intel doesn't recommend using 40 MHz channel width in the 2.4 GHz frequency band because of the limited number of non-overlapping channels.

Currently the following Intel Wireless Adapters support 160 MHz channel width.

Not all 802.11ac products support 160 MHz channel width.

If the AP does not, the channel width will be 20 MHz by default. If the AP supports channel bonding, then the channel width will be 40, 80, or 160 MHz.

Choosing Auto allows the Access Point (AP) to determine the channel width. Two configuration values are available for Channel Width: 20 MHz Only and Auto (default setting).Ĭhoosing a 20 MHz channel width effectively disables channel bonding. Not all legacy Intel® Wireless Adapters support 5 GHz. Choose Channel Width.Ī separate configuration parameter exists for each frequency band that the wireless device supports. Device Manager > Network Adapters > Properties > Advanced tab. 802.11ac Wave 1 allows for 80 MHz channels, while 802.11ac Wave 2 introduces 160 MHz channels.Ĭhannel bonding is configured under the Advanced Intel® Wireless Adapter Settings. High-density, or otherwise crowded RF environments may actually decrease in performance and introduce device disconnections if using a large width. You should have caution when increasing the channel width because this may increase channel interference. 802.11n networks can use a 40 MHz channel. Doubling the channel width will nearly double the wireless speed. 802.11a/b/g networks use a single 20 MHz channel. Channel bonding increases the data rate because data rate is directly proportional to channel bandwidth. You can save the file to any accessible location on your computer.Channel bonding creates more room for data by bonding or combining two or more 20 MHz channels into a single 40, 80, or 160 MHz channel.

This is how to see all the wifi networks available to you. The Intel® System Support Utility defaults to the Summary View on the output screen following the scan. Harassment is any behavior intended to disturb or upset a person or group of people. Check all wifi networks available to you via clicking to your Network Name Make sure 'show wi-fi status in menu bar' is selected so you can check these networks right from the menu bar, just select the drop-down menu under the wifi icon. Please run the Intel® System Support Utility and attach the report to this thread to gather more system information:ġ.Download the Intel® System Support Utility and save the application to your system.Ģ.Open the application and click Scan to see system and device information. Also, we would like to know if this issue occurs when using Original Equipment Manufacturer (OEM) drivers, too. If you have been experiencing this issue since you purchased your computer, please let us know if the Intel® Wireless adapter came preinstalled. However, we will gather more information to see if we can resolve this issue with the configuration you have been using. Thanks!īased on the troubleshooting performed, this issue seems to be AP/router sided. 20MHz setting and these symptoms are consistent and easily repeatable, so I have no doubt that there is a direct connection between symptoms and toggling this setting back and forth. Any ideas on why this is? My help desk also tried restarting the services on network list service and also resetting the Network adapter : netsh winsock reset. The AC 9560 works just fine on 2.4GHz WiFi set to Auto. During this time, Wired and 2.4GHz devices connected to the same router (Nighthawk R7000P set for Ch153 80MHz width continue to function fine. When the AC9560 loses WiFi, all of my other 5GHz WiFi devices also lose WiFi (LAN and Internet).

The WiFi disconnect problem is more frequent when downloading or transferring large files on the LAN. Switching the setting to 20MHz solves the problem, but 20MHz is not the recommended setting per Intel. and also the card that selling on indonesia also got same issue.(please see the attachment). I discovered that Channel Width for 5GHz set to "Auto" causes the computer to lose WiFi periodically. I believe issue is on your card not at wifi router and also on dell it self, because I try to snifing the packet and see the intel card just allowed to use 20MHz channel width instead use 40/80/160MHz channel width.
