New Macbook Pro 2023 can't connect to wifi 6e with a compatible modem from Bell Fibe 3.0

You sent me scurrying to do more research before responding.

Wi-Fi 6 and Wi-Fi 6E are not unique. Each is simply a use of 802.11ax modulation in the 5 GHz band, and for 6E, continuing up into the 6 GHz band. There is no bright-line differentiation, it is a continuum.

You have selected an extremely wide data channel at 160 MHz-wide channel your Router is using about channel 60. Its data spills over and competes with everything from channel 36 to 64, inclusive. Any neighbors trying to use those channels will interfere with your use, and they will accuse you of 'hogging' the 5 GHz spectrum, making their effective use slow to impossible.

MacOS prefers wider channels, and lower-numbered channels in the 5 to 6 GHz band carry farther, so lower-numbered channels with the same channel-width are also likely to be favored.

In my opinion, you are not using 6GHz because you are already hogging 5 GHz, and selectively connecting in 5 GHz instead.

My recommendation is to adjust your Router settings: back off the channel width in 5 GHz to a more reasonable and community-minded 40 GHz channel width. (or 80 if you must, but NOT 160.)

Then increase the channel width for your 6 GHz channel up to 160 MHz wide, and I expect you will selectively connect in the 6GHz band on your 2023 Apple silicon MacBook Pro 14-in and 16-in models, which are capable for connecting up there using wWi-Fi 6E rules.

assigning channel numbers and widths interact with each other, as data spills far away from the assigned channel and into adjacent spectrum. I use an inexpensive tool called Wi-Fi Explorer to get a picture of Spectrum use. Here is an example graph:

.

If your speed test is using the same Router settings in your screenshot, using an 80 MHz channel in the 5GHz band can produce, at the very fastest, 600.5 m bits/sec for each of your two antennas for a maximum possible top speed of 1201 M bits/sec.

You are reporting throughput of over 1700 m bits/sec. that requires the use of a 160 M bits.secs channel, which you have ONLY provided in the 6 GHz range.

in summary, your Wi-Fi 6e appear to be working just fine.

if you wish to confirm, post an Option-WiFi screenshot.

Could you please post the TEXT or a screenshot of:

 menu >about this Mac > (system report) > Network > Wi-Fi

and includes the Supported Channels section ?

another user posted his and it does not list channels above 165

I'm commenting here in hopes to save another person some time. My Arris G54 recommended a split WPA2/WPA3 for backward compatibility. I left the entire router on default and faced connectivity issues with the 6GHz band as it does not support WPA2.

There is another comment in here that mentions setting the WPA to 3 for their 6GHz band, and I can confirm that is the solution. In their scenario, I believe the WPA was configured per band; my configuration has all bands share the same SSID and password. Since each band shares the settings, the solution for me was setting the entire network to WPA3.

I was just fiddling with a very recent Verizon FIOS router, CR1000B.

They insist that to support 6 GHZ band you MUST use the same SSID for all bands, and the same password.

They require you to specify WPA-3 for the 6 GHz band, but if you prefer, you can keep WPA-2 for other bands. Next there is a master switch they call Self Organizing Network (SON), which enables Router features to accommodate automatic on-the-fly band-switching and access-point switching more readily.

I agree wifi explorer won't show it, but if you run "airport -s" from terminal it will show the 6E SSID. My suspicion is that "airport" and the network stack call (which is what wifi explorer uses) are making different system calls for the radio interface, since the latter can't see the SSID while the former can, or somehow the interface macOS uses is discarding the 6E SSID based on a bug or some non-complaint parameter, etc

Look at the attached screenshots (Juniper-6 is my 6E SSID) Also please note that Juniper-6 will not show up on the Wireless section of MacOS as mentioned before (not posting all my neighbours SSIDs)

Your RSSI of -83 is far below the threshold of about -65 to be a roam candidate.

Wi-Fi 6E on a new MacBook Pro may require that you use ONE SSID for all bands, according to this article:

I don't know how I did it. but it works on my Bell GIGA and Macbook pro 14 2023.

I put everything in AUTO in the page about Advanced Wifi on the routeur... and choose WPA 3 for security. Now, my mac connects with 6 ghz!

fast.com gives me that speed :

here's my 3 panels for Wifi advanced settings :

hopes that helps. oh, and here's the software version of my GIGA Hub

Hold the option key while you click on the Wi-Fi icon on the menubar, and transcribe or screenshot and post the values you see there. Like this older version:

.

I would use the same name for all 'Nom ** réseau'. Apple seems to be pretty strict about this. I do it in my settings. and use WPA3 on all of them.

You have excellent raw signal (RSSI) or about -43 dB. you must be very close to your router.

You have connected on channel 60, and succeeded (at least in the second screenshot) in using a 160 MHz channel using 1024 patterns per signaling interval, about 1081 bits/sec for each of your two antennas producing composite stream at 2161 bits/sec transmit rate.

That sounds really good. You are one step short of the highest possible data rate of 2402 bits/sec. If that last screenshot is all your neighbors in this 'network neighborhood', your results are truly remarkable.

<< lower 5.0GHz from 160MHz to 40MHz so that wifi6e would be prioritized because the 6.0 would be chosen by default using 160MHz. >.

YES, do that and you will make a great 6 GHz connection and live happily ever after.
