Wifi6e 6GHz channels always show an overlapping, interfering channel whether it's 5GHz, 6GHz. Does this affect packet loss? I suspect it may have something to do with WPA3 but why would the RF Spectrum show a 'red' interfering neighbor?</EM></P><P><SPAN class="lia-inline-image-display-wrapper lia-image-align-inline" image-alt="Wade_Carroll_0-1742915198079.png" style="width: 400px;"><span class="lia-inline-image-display-wrapper" image-alt="image.png"><img src="https://community.cisco.com/t5/image/serverpage/image-id/276258i22F122EE89EC0685/image-size/large?v=v2&amp;px=999" role="button" title="image.png" alt="image.png" /></span></SPAN></P><P><SPAN class="lia-inline-image-display-wrapper lia-image-align-inline" image-alt="Wade_Carroll_1-1742915246714.png" style="width: 400px;"><span class="lia-inline-image-display-wrapper" image-alt="image.png"><img src="https://community.cisco.com/t5/image/serverpage/image-id/276257i690B847F0087E1EC/image-size/large?v=v2&amp;px=999" role="button" title="image.png" alt="image.png" /></span></SPAN></P> Tue, 25 Mar 2025 15:09:10 GMT https://community.cisco.com/t5/wireless/rf-spectrum-overlapping-interfering-channel/m-p/5490867#M298612 wacarrol 2025-03-25T15:09:10Z https://community.cisco.com/t5/wireless/rf-spectrum-overlapping-interfering-channel/m-p/5490868#M298613 <P>Are all APs using the same RF profile or does each AP have their own RF profile?</P> Tue, 25 Mar 2025 15:54:28 GMT https://community.cisco.com/t5/wireless/rf-spectrum-overlapping-interfering-channel/m-p/5490868#M298613 RWelch-USA 2025-03-25T15:54:28Z https://community.cisco.com/t5/wireless/rf-spectrum-overlapping-interfering-channel/m-p/5490869#M298614 <P>Can you show your RF profile configuration please?</P> Tue, 25 Mar 2025 16:03:38 GMT https://community.cisco.com/t5/wireless/rf-spectrum-overlapping-interfering-channel/m-p/5490869#M298614 aleabrahao 2025-03-25T16:03:38Z https://community.cisco.com/t5/wireless/rf-spectrum-overlapping-interfering-channel/m-p/5490870#M298615 <P>One indoor profile (3 APs), 1 outdoor profile (1 AP). </P> Tue, 25 Mar 2025 16:45:15 GMT https://community.cisco.com/t5/wireless/rf-spectrum-overlapping-interfering-channel/m-p/5490870#M298615 wacarrol 2025-03-25T16:45:15Z https://community.cisco.com/t5/wireless/rf-spectrum-overlapping-interfering-channel/m-p/5490871#M298616 <P><SPAN class="lia-inline-image-display-wrapper lia-image-align-inline" image-alt="Wade_Carroll_0-1742921196912.png" style="width: 400px;"><span class="lia-inline-image-display-wrapper" image-alt="image.png"><img src="https://community.cisco.com/t5/image/serverpage/image-id/276299i993D67B52AC662F5/image-size/large?v=v2&amp;px=999" role="button" title="image.png" alt="image.png" /></span></SPAN></P><P><SPAN class="lia-inline-image-display-wrapper lia-image-align-inline" image-alt="Wade_Carroll_1-1742921223392.png" style="width: 400px;"><span class="lia-inline-image-display-wrapper" image-alt="image.png"><img src="https://community.cisco.com/t5/image/serverpage/image-id/276297i95FC3D870E4A0356/image-size/large?v=v2&amp;px=999" role="button" title="image.png" alt="image.png" /></span></SPAN><SPAN class="lia-inline-image-display-wrapper lia-image-align-inline" image-alt="Wade_Carroll_2-1742921259231.png" style="width: 400px;"><span class="lia-inline-image-display-wrapper" image-alt="image.png"><img src="https://community.cisco.com/t5/image/serverpage/image-id/276296i532990A1995EC746/image-size/large?v=v2&amp;px=999" role="button" title="image.png" alt="image.png" /></span></SPAN></P><P><SPAN class="lia-inline-image-display-wrapper lia-image-align-inline" image-alt="Wade_Carroll_3-1742921313623.png" style="width: 400px;"><span class="lia-inline-image-display-wrapper" image-alt="image.png"><img src="https://community.cisco.com/t5/image/serverpage/image-id/276298i8A1A6CAB54452B6F/image-size/large?v=v2&amp;px=999" role="button" title="image.png" alt="image.png" /></span></SPAN></P> Tue, 25 Mar 2025 16:48:44 GMT https://community.cisco.com/t5/wireless/rf-spectrum-overlapping-interfering-channel/m-p/5490871#M298616 wacarrol 2025-03-25T16:48:44Z https://community.cisco.com/t5/wireless/rf-spectrum-overlapping-interfering-channel/m-p/5490872#M298617 <P>One piece of advice: do not use a channel width of 160 MHz, as this will considerably reduce the number of available channels and you will have the same problem as in 2.4GHz. Instead, use a maximum width of 40MHz.</P> Tue, 25 Mar 2025 16:51:44 GMT https://community.cisco.com/t5/wireless/rf-spectrum-overlapping-interfering-channel/m-p/5490872#M298617 aleabrahao 2025-03-25T16:51:44Z https://community.cisco.com/t5/wireless/rf-spectrum-overlapping-interfering-channel/m-p/5490873#M298618 <P>I'm 100% with <A href="https://community.meraki.com/t5/user/viewprofilepage/user-id/51406">@alessandrodematos</A> .</P><P>It gets worse because the amount of 6Ghz spectrum available depends on your regulatory region.
