Wireless N Speeds on Cisco Aironet 1041N

[xpriceja1]

Hello, does anybody know how to enable wireless N speeds on this access point? It's operating in mixed mode via PoE. If I go into network interfaces -> Radio0-802.11N --> Settings, the highest data rate is only 54 mbps. Can N speeds be acheived in mix mode? Also, I thought this access point is dual-band, but I'm only seeing the one radio, is that normal? (see attached image)

Thanks in advance.

Hi Jason,

You see the MCS rates, thats your 802.11n

Also, keep in mind you need to allow WMM.

And you need to either have a OPEN unsecure network or use WPA2/AES to do 802.11n RATEs

Modulation Coding Scheme (MCS) Index	Number of spatial streams	Modulation used	Data Rate when GI=800ns	Data Rate when GI=400ns
0	1	BPSK	13.5	15
1	1	QPSK	27	30
2	1	QPSK	40.5	45
3	1	16-QAM	54	60
4	1	16-QAM	81	90
5	1	64-QAM	108	120
6	1	64-QAM	121.5	135
7	1	64-QAM	135	157.5
8	2	BPSK	27	30
9	2	QPSK	54	60
10	2	QPSK	81	90
11	2	16-QAM	108	120
12	2	16-QAM	162	180
13	2	64-QAM	216	240
14	2	64-QAM	243	270
15	2	64-QAM	270	300

Thanks for the quick replies everyone. Ok, I see the MCS rate table now. By WMM do you mean "World Mode Multi-Domain Operation"? It was disabled, but I enabled it at Dot11d and specified US country code, but still only connect at 54Mbps. I'm using WPA2-enterprise security, so that should work right? Anything else I can check?

Post your show run config .. Lets take a peek

QoS / WMM needs to be enabled and WPA2/AES ..

[George Stefanick]

BTW what client are you using to determine you arent getting 802.11n speeds?

[xpriceja1]

Ok, I was use TKIP encryption, so that's part of the problem, I switched it to AES-CCM. Also, I do not have QoS configured, how do a set a basic QoS policy?

Hi Jason,

the 1040 series is available as single band and dual band...

• AIR-AP1042N-x-K9: Dual-band Standalone 802.11a/g/n

• AIR-AP1041N-x-K9: Single-band Standalone 802.11g/n

To add to Rons point, you will not be able to bond on 2.4 so at best you will get 144

Switching to AES got me up to 144 Mbps, which is the max according you, so I'll take it! Thanks so much for you help everyone!

[George Stefanick]

LOL, accroding to me! I like the tone to that !

Yes, if you get a 1042 with a a/n radio you can bond and you will get 300.

Cool ... Enjoy!

Thanks for supporting the rating system ..

My cisco function only 54mb, how to configure 150mb or 300mb?
