situation :
Router : TL WR1043N set at "11bgnmixed" auto channel width and max Tx of 300Mb.
Remote : Edimax EW-7728In PCI Card, which should support 802.11n class conenctions. Client is, ofcourse, running Arch (64 bit) with WICD as connection manager.
Problem :
Connection speed is 802.11g class. IWLIST RATE shows just 54Mb/s.
How do I configure the card to work at 802.11n (300Mb/s) speed ?
Thanks
Edit on 20-Jan-2010:
The problem is with the rt2860 kernel drivers.
The solution ? Use the manufacturer driver. Thanks to schuay we have it in AUR here - https://aur.archlinux.org/packages.php?ID=14557.

Always include the chipset and driver you're using when posting a wireless query. Manufacturer name and model number are irrelevant under linux.

It's a Ralink 2860 device, and teh driver is nuiltin in the kernel.

There are two drivers for that chipset - rt2800pci and rt2860sta. You need to check that the driver you choose also supports 11n - hardware support on its own is not sufficient.

Thanks Tom
I'm using rt2860sta.
iwconfig wlano scan shows "Protocol : 802.11b/g/n" as expected, and also "Bit Rates : 18 Mb/s" (??? very strange).
iwconfig wlano rate returns
"unknown bit-rate information
current Bit Rate : 54 Mb/s"
strange

Don't trust iwconfig, it can report wrongly. Did you do some actual benchmarking?

Sure
I can transfer large files at 2-2.5 MB/s which is consistent with real life g class speeds (and were actually achieved also with the previous wireless card which was a class g card).

try setting your router at n only and see or encryption to cipher aes only... i remember having issues with this on my 1000h eee, in the end i swaped out my network card for an intel card.

Will try later.
But there must be a way to manage the driver. What if I want teh card to only use b class connection ? or control any other parameter ? How is it done ?

The parameters can be set by iwconfig or by params to module, if the module support it. You can see the possible parameters to module with modinfo. The rt2860sta dont have any param related to a/b/g/n but for example iwlagn have (11n_disable disable n)
EDIT. Of course others parameters can be set in the source code..

You need to stick to AES encryption. Anything else sets a limit to 54MBit/s. See also this thread: http://www.dd-wrt.com/phpBB2/viewtopic. … sc&start=0

@kazuo : thanks.
@AndyRTR : thanks. Am using WPA2+AES.
any more ideas ?
