[SOLVED] Help Please AC1900 pci-e wifi adapter 5ghz problem

[Liam]

Hi guys

I recently bought AC1900 Pci-e adapter it uses BCM4360 chipset
after installing latest drivers on windows 10 and 7
it won't see 5ghz wifi on windows 7 and with netsh command, in radio types supported section, ac is not listed but in windows 10 there is no such a problem.

can anyone help me please ?

Windows 10

Windows 7

Run netsh wlan show all. Which driver from the asus website did you install? There can be some limitations with elder OS’s like 7. msinfo32 also shows stuff like wifi info. Sadly Windows 7 did not have support for Wireless-ac at the time that it came out.

I'am using latest driver released in 2017/07/17
tried netsh wlan show all unfortunately doesn't show any 5ghz networks.
I'll try fresh windows install maybe it helps.

Unfortunately, Broadcom has not kept up. You could go with a PCIe adapter for something like the Intel mini-pcie cards that do Ax.

Not all PCI-e cards support DFS channels... sometimes it's drivers...

Everything works fine in windows 10, wifi connects in 1.3 Gbps and transfer speed via iperf is 400mbps, but it can't see AC or 5Ghz in windows 7 !!
tried 3 different drivers and fresh windows 7 install, both can't solve problem.

What is the actual make and model number of the adapter, you've never said?

I think problem solved, i just unchecked the Auto select channel including DFS channels not 5ghz wifi appeared !

I have to ask the obvious question...... Have you tried the most recent driver from Asus rather than the Windows-supplied version? It looks like that would be Version 2.1.4.3, 2017/07/27 (Driver = 12/02/2014, 6.30.223.259).

Yes i am using the latest driver
as i said before i just unchecked the Auto select channel including DFS channels now 5ghz wifi appeared !
i don't know why this problem not exists in windows 10, i can connect even when DFS channels selected

10 years or more of O/S and driver model improvements should get us something.
