BCM94352Z: no 5GHz wifi connexion (Lenovo Z51-70)

Recommended Posts

Hello,

 

I installed a BCM94352Z on my Z51-70 but it is only possible to connect to the 2.4 wifi network.
I tried the same card on Windows 10 and i can connect to the 5G wifi network.

 

So i don't understand why the wifi card cannot see the 5G wifi network on Mac OS El capitan.

Can you help me please?

I've found that, in OS X, it's better to distinguish both networks than use the same SSID on both 2.4GHz and 5GHz. I personally had an issue with 2 x 2.4 & 5GHz networks that shared a common SSID... until I used 2 x separate SSIDs. All my troubles then went away and I could connect safely and in a stable manner to one or the other.

 

Symptoms were different from yours though as I was experiencing connection dropouts; doesn't seem to be the case for you, so I'd say the patches Bronxteck linked to are probably required.

Dear all,

 

Did Bronxteck's link help you to solve your problem, or did Hervé's advice about SSID work for you? Actually, I just found out, thanks to your topic, that it was possible to change the wifi chip of a Z51. Is it really THAT easy? Or do you guys have any advice or best practices to "physically" do it?
 

 

 

 

 

 

 

For instance, are any of these suitable for our z51-70?: http://www.amazon.com/s/ref=nb_sb_noss?url=search-alias%3Dcomputers&field-keywords=BCM94352Z+

 

 

I hope I don't "steal" mixmaster57's topic with my questions, if so, do not hesitate to tell me or to indicate where we can find such info, if specific for Z51-70!

 

 

 

 

 

Thanks,
