WLAN (Broadcom 802.11ac) won't connect

[Sereiya]

Having trouble with my new G750, it refuses to connect to anything via WLAN.
With the preinstalled standard drivers he is able to catch the SSIDs and establishing a "connection" to my Fritz!Box router. All the settings like IP, gateway etc. seems fine, but Windows reports a limited connection. I cannot use the connection, it's not even functioning to ping my router or anything else.
Then I tried the newest driver from asus.com. Even worse, I was completely unable to connect (He fails before asking for the password).
The older driver from asus.com made it simple. It just didn't found wireless networks anymore. In a last-ditch attempt I tried a win7 x64 driver, but as expected it didn't worked.

I tried to connect to my router and my android phone hosting a hotspot. Both worked with another device, but not with my G750.

I fear that I got just 'the' device with a broken wireless adapter. 😞

Can anyone help me?

Edit:
I just found an old thread here suggesting to deactivate the WLAN-n support. It's working with WLAN-g. But I don't buy a such expensive notebook to use an antiquated standard...some suggestions aside from "waiting for newer drivers"?

Hi,

I got a same problem on my G750 JW, when I use steam to download Total War, the highest speed I can hit is 2 MB/S, but the lowest one is 0, the speed is up and down, but my roommate's ace laptop has a good download speed about 1.4MB/s on steam. After I disable WMM, my download speed is about 600kb/s, and never hit 0 again. Do you guys have any idea for me to fix the problem? or I just to change another one in BestBuy.

Thank you !!!

Junwalker, try to make all that told hmscott or better try to change to another one(better with other network adapter):)


hmscott, thanks for the article (I forget about this site) but all this action is for cases when wireless connection drops frequently or have a low speed - it's a different case, not my. My FRITZ!Box is connected to Dslm (or other device eg Broadcom) with speed ~11,6 Mbit/s and uTorrent can download with the same value(when WMM is disabled of course :)).

I've disabled WMM only in the Broadcom 802.11ac Properties. There is WMM option in FRITZ!Box but not in my. Maybe there is no WMM option in this model - FRITZ!Box 7330(I have actual firmware).

I thought that my network adapter has a defect, but after your story and story of Junwalker there are 2 version: defects with some of this network adapters and problem with driver(not correctly realized processing of this field).

I've tried to install the newest driver (it was 6.30.223.143) but I had error message "Error "Update.cpp 1186"", Setup cannot continue.". So I must wait.

Hi Fuchs, after upgrading my wireless driver from low level to 6.30.223.64, my download speed is good ( about 1.8mb/s) now, WMM setting is auto, and IBSS is 802.11 a/b/g/n auto

Fuchs, you can try unzipping the driver package and use the Windows Device Manger to update from local files for the Broadcom device:



The Windows installer for the diver might not like the environment it wakes up in, so let Windows do the searching through the folder for what it wants for the update.

hmscott, I've tried to do it like this but Windows decide that I've already "The best driver software for my device" installed:)
(I've extracted setup.exe and tried also... same result)

Sorry to hear that, it must be a locale issue. When Asus releases the rest of the updates for the G750 series, we should get an updated Broadcom 802.11ac driver 🙂

Hi. Sorry for hijacking this thread.

Anyone knows how to force the Broadcom 802.11ac to connect to AC ?
I got the RT-AC56U router, and my wifi adapter keeps connecting to 802.11n instead of 802.11ac.
Any ideas?

I have the 2,4 ghz broadcast SSID set to Skynet and the 5ghz is named Skynet 2.0.
My laptop and my iphone5 are connected to Skynet 2.0 and my PS3 (and my girls laptop) is connected to Skynet.
Everything works good, but it bothers me that my laptop won't connect through the AC protocol.

hello Krebb, i have the same issue with Broadcom 802.11ac, after upgrade my rog to windows 8.1 i had connectivity problem...

I have slow speed with my 750jx and 2wire ATT modem.
I have tried different drivers in 8.1 and then upgraded to Win7 which seems better. Still only 100K speeds but better than the 40 - 0 K 8.1 had.
I tried all suggestions here, turning off WMM, changing channels and moving the router. None helped 8.1.
I will try a 802.11ac router as soon as I have the money, but the problem might be the four cell phones and Obii talking on different bands against the laptop. My Gateway laptop is solid at 2Mb under Win7 with 802.11b.

I seem to be having connectivity issues with the Qualcom Atheros AR9485WB-EG.
The card keeps disconnecting from my network, so I have to reconnect manually.
I also am missing all of the options is the "advanced" tab on the Device Manager. I have tried updating drivers, but of no avail.
Does anyone have anything to contribute with?
As I am stuck, all help is good help.
