Broadcom card not connecting to some networks Solved

Question

Hello,

I can no longer connect to networks with my Broadcom BCM43142 802.11 bgn Wi-Fi M.2 Adapter (7.35.352.0) but I can connect through my phone's tethering.

When I try to connect to Wi-Fi (work or home), I only have one or two seconds before I get the error message "We couldn't connect to this network." I have updated the drivers, restarted the network card, reset my connections by clearing them, run diagnostics but nothing works. My card detects the available connections but cannot connect at all. It’s not a Wi-Fi issue since I can connect normally with my other devices and a wireless USB dongle.

Thank you very much for your responses and your help.

Configuration: Windows / Firefox 73.0

Hi,
This card only supports 2.4GHz, not 5GHz. It's possible that your router is configured for dual band, which could cause issues. Just be aware that what I’m telling you comes from the HP forum; I'm not an expert on Wi-Fi as I use it very very little. Still, try to check in your router's interface to see if there's a way to disable the dual band to keep only the 2.4GHz.

It was very clear, thank you! However, it did not solve my problem; I still cannot connect.  Okay, but was the installation done correctly? No error message or message indicating that a better driver is already installed?  For the unknown device ID: ACPI\VEN_INT&DEV_3402.  For this device, do the following:  Download this driver --> click here and place it in your documents.  Right-click on --> Intel-FORCED-DPTF-10x64-8.6.10402.11528-drp Select --> 7Zip Choose --> extract to "Intel-FORCED-DPTF-10x64-8.6.10402.11528-drp\"  Go to Device Manager. Right-click on the device --> unknown: ACPI\VEN_INT&DEV_3402 Update driver Browse my computer ...... Choose from a list of drivers... Have disk Browse Go to your documents Go to the unzipped driver folder --> Intel-FORCED-DPTF-10x64-8.6.10402.11528-drp Folder --> Intel Folder --> FORCED Folder --> DPTF Folder --> 10x64 Folder --> 8.6.10402.11528 Select the file --> dptf_acpi.inf and OK Restart  In image:    Let me know how it goes  @+  -- the radiation level is higher at Pôle Emploi than at Chernobyl.

re  The installation went smoothly and there were no error messages.  ok  It works now, thank you very much! Could you explain to me what went wrong?  the 1st device is for the Wifi connection (Broadcom BCM43142 802.11 bgn Wi-Fi M.2)  the 2nd device is for the chipset of your pc/your motherboard (ACPI\VEN_INT&DEV_3402)  was the pc not originally running W10?  in your case, I assume it was a Windows (W10) update that "hit" both devices  with the .INF file of the 2 drivers, we got things "back in order" (driver/device updates)  if you have any questions...  if everything is ok for you, you can mark your topic as resolved --> click here  thank you  @+  -- the radiation level is higher at the employment office than at Chernobyl

Hello everyone,
I'm having the same problem as you, but I don't understand the unknown device, I don't have one.
The configurations are the same, I was on W8 and switched to W10.
Thank you for your help.
