Qualcomm Atheros AR9485 802.11b/g/n WiFi Adapter fails to connect to WiFi N

Notebook Version: HP Pavillion g7-2233cl

WiFi Version: Qualcomm Atheros AR9485 802.11b/g/n WiFi Adapter; Driver 10.0.0.212

Router: Western Digital MyNet N600; Firmware 1.04.16

Operating System: Windows 8

 

Router is dual band. 2.4GHz is set to G only (for Android phone, iPad, PlayStation 3 [just in case it needs G]). 5GHz band is set to N only. Both use WPA2 Security. Both have different SSIDs (tried the same once, still didn't work). Channel width is 20MHz for both. Both broadcasting SSID. 2.4GHz is set to Channel 7, 5GHz is set to channel 153.

 

I can connect all devices in G mode. I have 2 of the above laptops which also ONLY connect in G mode. I know it's not architectural interference as we usually use our laptops about 8 feet from the router. I have tried using WPS, both key and button connection. Connects, just using G. On the WiFi list, I never see the 5GHz SSID in the list.

 

Please tell me what's going wrong.

Hi:

 

The wireless card in your notebook is a single band (2.4 GHz only) wireless N card, so it does not receive or transmit on the 5.0 GHz band.

 

I recommend you set your routers 2.4 GHz band to Mixed Mode (B/G/N), vice G only, which will allow all of your devices on that frequency to connect at their best speed.

 

Also make sure your router's WPA2-Personal security is set for AES encryption, not TKIP.

JustinJ,
 
Do you have the same router that is in the original poster's comment? If so, take a look at the manual below:
 
 
Starting on page 30 it lists the advanced settings and on page 36 it will show you where the option is to change the bands. 
 
Best of luck,
Kyle

I am having the same problem with this adapter in W10.  What is the meaning of b/g/n in the model number of the adapter?

 

Thank you,

Thank you,


Means you only have 2.4ghz wifi nothing more. The /n isn't true 5ghz that is a misleading. You have to have both a/n aka a/b/g/n to be considered true dual band.
