Ralink Routers 40-MHz channel

[mrc_torres]

Ralink Routers are not transmitting in 40-MHz channel, no matter what setting to use or which adapter is used on the client.

[BrainSlayer]

config details missing, device type missing. client adapter type missing

[mrc_torres]

Ok, sorry.

Device: D-link DIR-600 B1

Config are default, except:

• Channel Width: 40 Mhz;
• Control Channel: upper or lower (tried both);
• Wireless Channel: tried all;
• Security Mode: WPA2 Personal;
• WPA Algorithm: AES

Client adapter used:

• Realtek RTL8191SE N 300 Mbps
• TP-LINK TL-WN821N 300 Mbps

Client SO: Windows 7, Vista and XP

BS, running the command "iwpriv ra0 set HtTxStream?=1" in a DIR-600 B solves the problem.

[mrc_torres]

I think probably in rt2880.c file where it says "Ht_TxStream" and "Ht_RxStream" should be "HtTxStream?" and "HtRxStream?" respectively, is not it?

[BrainSlayer]

according to documentation and also the driver code HT_TxStream is correct

[mrc_torres]

But only without the "_" works and the Ralink routers are transmitting in 40-MHz. Could you try it, please?

Replying to BrainSlayer:

according to documentation and also the driver code HT_TxStream is correct

hmm, typo?

HT_TxStream=2 (wive-rtnl) vs. Ht_TxStream=2 (dd-wrt)

[BrainSlayer]

mmh interesting typo. i guess we can close it now since its corrected

[mrc_torres]

I think that the next test build will leave many ralink n users happy ;-)

[mrc_torres]

Still not working in build 16994 (Dir-600 B1). HT 40 only works when running the command, without "_", exactly as below:

iwpriv ra0 set HtTxStream=1

[BrainSlayer]

your fix has been already implemented. there is nothing more i can do

[BrainSlayer]

the iwpriv command has also nothing todo with the configuration file. HT_TxStream=2 within the config file is correct and there is also no bug visible here

I think im having the same issue. Im on 17201. I have tried on 2 asus with ralink. 40Mhz only works with AES like said on wiki, but it works for like 10 minutes then go back to 20Mhz.

Fixed on latest version! b18740. At least on Asus RT-N13U B1
