Macbook Pro (M2 Pro, 2023) doesn't connect to 5GHz Wi-Fi network at all

Hi everyone,

It happened to me as well but I solved it.

Apparently in my case, the problem was a bad hdmi cable.

I was checking the wifi using speedtest. When I disconnected all of the cables connected to the computer and turned off bluetooth, the internet worked just fine.

After that I started a debug session to find the culprit, which was the hdmi cable. After replacing the hdmi cable to a different one it works well.

Dear Apple,

I'm having exactly the same issue, I have also tried all the above that I could find, including deleting all the other services. I've also tried the test-account and foundthe same result. My Macbook Pro 14 inch M2-pro will only connect to 2.4GHz wifi and not the 5GHz band. My iPhone 12 mini is next to it and is connecting properly.

Please advise what I can do.

Best,

Jurgen

WiFi not staying connected. If your router is using WPA2/WPA3 Mixed Mode "Wireless Protected Access", try changing your router to just WPA2. Not all routers play nice with Macs that are trying to use WPA2. I cannot give you exact instructions, each home router is different. Check with your router manufacture. If switching to just WPA2 does not improve the situation, then you can always switch back to WPA2/WPA3 Mixed Mode. Try disabling IPv6: Ventura: System Settings -> Network -> Wi-Fi -> Details -> TCP/IP (tab) -> Configure IPv6 -> Link-Local Only

I finally found a solution to my M2 Macbook not connecting to my 5g network (with no problem connecting to my 2.4g network). The problem is something with my router NOT the computer. My internet is provided through my apartment building and I am only able to use the provider they contract (CenturyLink). All my other devices (including an imac, an M1, ipad, and iphones) have no problem connecting to our 5g network. However, when I would connect my M2, it would stay connected for about 5 minutes and then get kicked off. I went to a local coffee shop I could verify uses internet provider and has 5g and was able to stay online there with no issues. So, I knew it was an internet issue not a computer issue. I recently purchased a second router (Linksys Hydra Pro 6 Mesh WiFi 6 Router - WiFi Extender Replacement - MR5500-AMZ - Mesh WiFi Router for Wireless Internet ) and pluggged it into my current router (because I can't get rid of that due to my living situation) and now my M2 Macbook is able to connect to 5g no problem!!!! This took about 3 weeks of trouble shooting to get to the source and figure out how to address the issue but now the problem is solved.

I just returned my M2 Max because it would not connect to other computers on my home network! It sees the computers but always fails to connect. I am not sure whether i was using 5G or 2.4 (also a TJ Router)wireless but I need to access files located on my other two macs and this M2 would not function and so I took it to the Apple "Genius bar" what a bunch of turkeys, they said they couldnt troubleshoot a network problem because their store system is a secure network with no public connections BS! I think this model has issues and to hide the Apple is instructing their tech staff to avoid any telltale network failures. I had purchased it at a Microcenter store and so I made an appointment for a consultation and if it needed fixing then fix it,instead they joyfully accepted it as a return even the Apple tech onsite agreed they couldnt troubleshoot a netork problem.And so It was returned! Not sure what I am going to get next,but I am loosing the faith in Apple and have been buying Apple computers since 1986 !

Same problem here. 5Ghz works fine from my M1 Macbook Pro, but not from my M2.

On the 5Ghz network, The M1 shows the correct router address (192.168.0.1) & assigns a local IP address. The M2 does not show the router address. DHCP bug?

I am using CenturyLink Calix Wifi Router Model C844G.

Same here, I had the same issue and believed it was just the wifi problem, but hey, all my devices connect no problem, including my PCs Android and so forth.

Funny how Apple keep surprising me all the times, overpriced/luxury product that doesn't work accordingly to their pricetag.

Same thing happened to my and I found out it was my hdmi cable. recently I added a 2nd monitor connected via hdmi cable and then the 5G issue happened afterwards, reading thru comments and troubleshoot, the one that I did was disconnect the hdmi cable and I am able to connect again to 5G.

Hello

your issue resolved ? Because I am facing exactly the same issue.

Regards

Also having this issue. I’m using a Calix 844g router with CenturyLink. Have messed with everything I can possibly think of in the advanced modem settings and it’s still not working on 5G. Also, it’s painfully slow on 2.4G. I have a 2015 MacBook Pro that I just replaced that is reaching 10x faster d/l speeds on the 2.4G (and it connects to 5G with no issues)

Having the same issue over here with a M2Pro 16.

I separated my two networks 2.4 and 5G, disabled IPV6, tried changing DNS, changed the router channel, and I even upgraded to Mac OS Sonoma... and now it is worse. Before it was saying "No internet connection" as if it was not able to acquire an iP address. Now it cannot even connect to the 5G.

I went to an apple store and the genius was not able to identify what was happening claiming that the network in the apple store was 5g and it was connecting fine.

Really frustrating

I cannot remember how i fixed it now but I tried a few things that seems have fixed the issue.

1. Change the HDMI cable - I think to have a good one makes a difference
2. Add HDMI to USB-C Adapater (I use one because it works well with monitor configurations)
3. Restart your router (mine cannot even seperate channels so unable to pick 5GHz)

Haven't had any issues since

If you set up that 5Ghz SSID to use WPA3 personal security and your MacBook Pro is attempting to use WPA2, then it will never connect unless that SSID was configured for either of WPA2/WPA3 security.

all of the solutions here haven't worked on me, what worked was just setting my router to WPA2/WPA3 mode, turns out my mac just isn't happy with having the options chosen for it

Hi pnwclw,

Thank you for using the Apple Support Communities! You have tried great steps so far. Have you also tested in another user? Being able to see if the issue occurs in another user account will to identify if it is something that is affecting your entire system or just one particular user account. To do this, you'll want to set up a Test User account and then try to replicate the issue in that account.

1. Choose Apple menu > System Preferences, then click Users & Groups.

2. Click the lock icon, then enter an administrator name and password.

3. Click the add button (+) below the list of users.

4. Complete the fields shown for a Standard or Administrator account, then click Create Account (or OK).

5. Go back up to the Apple menu in the upper left of the computer and select "Log Out". At the login screen, choose the "Test User" just made.

6. Once inside the Test Account, try to replicate the issue to determine if it just occurs in one account or on the whole computer.

If the issue remains in the test user, we recommend that you reach out to Apple Support directly to take a further look. Please reach out here:

Hope this helps!

Have a great day.
