Atheros AR9485

Hello everyone

I have problem with my wireless adapter.I can't change it to run on 802.11n.There is no option in the advanced settings of the device manager.All i can see is:

802.11b Preamble-Long or short or only Long
AdHoc 11n-Enable,Disable
Dynamic MIMO power save-Enable,Disable
Network adress-value:
Receive buffers-256
Scan valid interval-60
Transmit buffers-512

I can't find neither 20-40mhz,nor 2.4Ghz-5Ghz options.Its strange because the adapter can run on "n" mode with up to 150mbps and all am getting is 65mbps.I tried to write the key in CAPS as someone mentioned in this forum before,but it didn't help.Also i have the latest drivers.

Any suggestions?

Regards.

 

Lots of bad news incoming.

First and foremost your wireless card is crap- one of the most troublesome Wi-Fi cards ever to hit the market (only Intel 2200 seemed to be worse than that).
It tends to slow down to a crawl in 802.11n mode while it works perfectly fine in 802.11g.

Also it does not support 5GHz so don't expect this option to be available because it couldn't have been even if settings like that depended on a Wi-Fi card- and they don't.

Setting band, channel width and connection type (802.11n or 802.11b/g) and security (WEP, WPA, WPA2) and so on is all done on the router- the router is in charge and the client device has to comply.

Now to top it off- you're already connected at 802.11n- your connection speed id 65mbps which is above 54mbps that is possible on 802.11g.

65mbps is possible on 20MHz channel width- your only hope is to force 40MHz channel on the router which would bump you to 135mbps.
This may or may not be possible as routers that are certified should not allow that. Only allowed settings are 20MHz or AUTO (40MHz or 20MHz if no neighboring networks are detected)

If you can't force 40MHz, just go buy an Intel 6200 which is a very good and cheap dual-band card and replace the Atheros in question.

Sorry if I come across as an unfriendly person because I wasn't very constructive but the problem is that is the card is very bad and you can't fix it.
With a bit of luck you can make it bearable but that's all.

 

You didn't come as an unfriendly person.I didn't want to change the wireless card,because my notebook is still in warranty,in fact i bought it 2 days ago.But it seems that i have to do this procedure in order to achieve higher speeds.

Thank you.

 

It most likely won't affect your warranty.
I don't know of nay manufacturer that disallows HDD, RAM or Wi-Fi replacement/upgrade.

As long as the new part is not the one that caused a problem they will honor your warranty.

Note that HP and Lenovo need cards dedicated to their respective brads- other cards won't work because of whitelisting.

 

Thanks for the mention of the Intel chip. I was searching for a replacement for the Atheros card that comes with a Samsung NP350E7C and stumbled upon this thread. The Intel Centrino Advanced-N 6200 is an excellent card and delightfully inexpensive.

The 6200 works fine with Win8 using the Win7 drivers. So, is there any reason, other than to get prettier graphics, to also install the Intel ProSet wireless software?

 

Intel software is nice if you work in some kind of business environment, but it connect way slower than windows build in.

In short, no.
