MBP MID 2012 - Wifi Connection Drops

Hello team,


I have a MBP MID 2012 (i7, 1tb SSD, 16gb RAM) with the latest Windows 10 version, and I am experimenting constant and random wifi connection drops.


I have been investigating, and I found the following threads that seems to be the most interesting ones:


But In my case, having the following WIFI adapter, I don't have the Power Output Option within the Advanced tab under the Device Management menu, and the uninstall and re-install of the drivers didn't work either.


*It is proven that with other PCs and phones the connection is OK.

My WIFI adapter Info:

SSID: Eipoks 5 GHz

Protocolo: 802.11n

Tipo de seguridad: WPA2-Personal

Banda de red: 5 GHz

Canal de red: 36

Dirección IPv4: 192.168.0.11

Servidores DNS IPv4: 192.168.0.1

Fabricante: Broadcom

Descripción: Adaptador de red Broadcom 802.11n

Versión del controlador: 7.35.118.83

Dirección física (MAC): 7C-D1-C3-84-54-74


What I was able to realize is that it happens after the computer gets stuck, and I have to do a "hard" reset, by maintaining the power button pressed for 5 seconds.


I have been thinking in making a substitution of the Wifi device. Is it possible to do it in my MBP MID 2012?


Thanks in advance,


Best regards

Hello all,


After several tests, I found the guilty stuff that was causing WIFI drops with my mac: it was the bandwidth configuration of my router. I changed it from 80 Mhz to 40 Mhz and since then, I can say that after several continued hours using the MBP, it no longer disconnect from the WIFI.


I realized that it was a problem of my router - wifi - environment because I tested in in other several places, like my mom's, office, and other friend places, either 2,4 and 5 Ghz WIFIs, and those tests maked it work.


I think that the reason behind is the WIFI saturation that my flat has, due to my neighbours routers, and as I read across the internet, that the more Bandwidth, the faster it is, but at the same time the less stable the connection becomes, plus, the network adapter is 802.11a/b/g compatible, but not AC.


Hope this experience helps other people with the same problem!


PS: I maintained the latest network card driver.


Best regards

Hello,


I have tried both of them but the behaviour is the same... I am starting to think that the wireless card is broken somehow...


Do yo know if these problems could be related to a malfunctional wireless card? Maybe it will be fixed by just replacing it, could be?


If have found this in ebay:

I actually can't reproduce a WIFI drop under the macOS partition....


I will try the .49 and .40 versions, but I don't know how to make Brigadier download the specific BC package which contains these driver versions.


Could you help me with this please? I have been seeking in the internet for a detailed step by step and I wasn't able to find it...


Thanks in advance,


Best regards

Here is an example..


~/Documents/brigadier-master/brigadier -h

Usage: brigadier [options]


Options:

-h, --help show this help message and exit

-m MODEL, --model=MODEL

System model identifier to use (otherwise this

machine's model is used). This can be specified

multiple times to download multiple models in a single

run.

-i, --install After the installer is downloaded, perform the install

automatically. Can be used on Windows only.

-o OUTPUT_DIR, --output-dir=OUTPUT_DIR

Base path where the installer files will be extracted

into a folder named after the product, ie.

'BootCamp-041-1234'. Uses the current directory if

this option is omitted.

-k, --keep-files Keep the files that were downloaded/extracted. Useful

only with the '--install' option on Windows.

-p PRODUCT_ID, --product-id=PRODUCT_ID

Specify an exact product ID to download (ie.

'031-0787'), currently useful only for cases where a

model has multiple BootCamp ESDs available and is not

downloading the desired version according to the post

date.

Look at how the '-p' qualifier is used. As you can see the '-p' can be used to select a specific 'product' package.


The '-m' qualifier is the actual Model Identifier, not the literal string 'qualifier'. 😉
