I’d also suggest using 40 MHz channels in 2.4 GHz, because then the jigabits get there faster in luxuriously wide fastlanes.

If Phase 1 was “Use all 11 Channels” – was Phase 2 - Disable any “multicast/broadcast filtering mechanisms” 😉 Sorry. Just popped in there since I just finished writing a message about why “unfiltered multicast/broadcast” traffic is bad mojo – and why can’t just “turn it on”. 😊 Christopher Johnson Wireless Network Engineer Office of Technology Solutions | Illinois State University (309) 438-8444 Stay connected with ISU IT news and tips with @ISU IT Help on Facebook<https://www.facebook.com/ISUITHelp/> and Twitter<https://twitter.com/ISUITHelp> From: The EDUCAUSE Wireless Issues Community Group Listserv <WIRELESS-LAN@LISTSERV.EDUCAUSE.EDU> On Behalf Of Enfield, Chuck Sent: Wednesday, August 26, 2020 12:11 PM To: WIRELESS-LAN@LISTSERV.EDUCAUSE.EDU Subject: Re: [WIRELESS-LAN] [EXT] Re: [WIRELESS-LAN] 2.4Ghz channel designations [This message came from an external source. If suspicious, report to ab...@ilstu.edu<mailto:ab...@ilstu.edu>] The four-channel plan made sense when AP density was lower and before OFDM (back when spectral density graphs had long tails.) I’m not sure if it was every really better than a 3-channel plan, but there was a case for it. Even if it was better for 802.11b, 802.11g and the iPhone made it obsolete.

I have a consultant who is suggesting using all 11 channels in our high density dorm situations, arguing that signal interference will affect throughput less than the delays from protocols where the 3 channels are within hearing distance of each other. This doesn't make sense to me. If you in your situation have found using all 11 channels to be an effective solution vs the 3 channel non-overlapping approach, could you explain to me why you made that choice, and what your on-the-ground experience is with this configuration?
