802.11a/g/n optimizing for compatibility

How to ensure maximum client compatibility and stability in 802.11a/b/g/n networks?
I am running a Wireless network based on the WLC 5508 6 SW version, (with WCS mgmt) and 1142 APs. I would like a broad variety of clients, old G clients and new N clients to experience a stable connection to the network. I see Apple Macbooks, Lenovo-, Dell- and HP laptops in addition to HTC smartphones and iPhones on this network.
I am having issues with some types of clients experiencing "unstable" connections. They are able to get a link for a variable ammount of time, then suddenly loose connection for a short period of time before reconnecting. These clients mostly use a third party SSL-VPN link over my wireless, therefore the loss of connection can be quite annoying. From time to time some of these clients seem to be flapping between access points but not seamless like roaming should be, rather with a short stop in connectivity before reconnecting.
Previously we had a 802.11g Aruba wireless network in the same location. It had no such difficulties. This points me toward the config parametres in the controller.
Which 802.11 b/g/n and WLAN parameters can affect this? I am looking for a document describing a best practice for setting up these parameters, or if someone here has input to a successful stable setup as the configuration guide only says e.g. "Enable if you want Aironet Information Elements" does not help in deciding if I want this
My WLAN is set up with WPA2/AES PSK
and a guest network with web auth
Examples of parameters:
which Radio policy (bgn or gn)
Aironet IE?
MFP (disabled or enabled)
QoS profile?
can CCX location measurement affect performance?
Which Data rates should be set mandatory/enabled/disabled?
MCS (data rate) settings for 802.11n
anything I have forgotten?
The goal is:
A simple, no hassle network providing maximum compatibility with different clients with a plus of 802.11n speeds for compatible clients

Hey! I implemented your suggested improvements and the first impression is good!
on 802.11a and b/g I disabled lower datarates, set 12Mbps to mandatory and the higher ones to supported. The instant improvement was the RTT measurements I made (previously they averaged at about 13ms (to an internet site) after the change they dropped to about 3-4 ms on average! I would say this is a very significant improvement!
I have not been able to get any feedback from the user community yet :), but it sounds promising...
I am still looking for some more insight into these issues, so if someone still has some ideas, please let us know!

802.11a network not supported for this Country Code

Hi, I get the following error whne enabling 802.11a network on a AIR-WLC2106-K9. Country is set to ID (Indonesia)
>config 802.11a enable network
802.11a network not supported for this Country Code
Yet, on a AIR-CT2504-K9, set to same country code there is no problem.
Is this a WLC model or version issue? WLC2106 is on version 6.0.199.4 while the CT2504 is 7.0.220.0
Andrew

Well is it the only country code selected? Also you might as well upgrade the 2106 to 7.0.x and move off the 6.0.x. Since your 2604 is at that code you might as well upgrade the 2106 and see. I'm guessing that you have the same APs and the APs are for that country.

802.11A

Has anybody connected their MacBook Pro to an 802.11A router? The reason I ask is that currently my signal keeps on dropping out. I am using an Airport Extreme Base Station. The MacBook Pro wireless is much better then the Aluminum Powerbook which may be part of the problem. I am able to see more routers then before. Besides mine I see 2 Linksys Routers on channel 6, 1 Netgear Router on channel 11, 1 Unknown brand Router on channel 11 and a Microsoft Router on Channel 6. I have changed channels, turned off encription and tried Interference Robustness to no avail. I decided to connect to one of those Linksys Routers and no problems. So I am thinking that if I get a 802.11A Router I will not have any problem because the Frequency will be so much different then the others. PS I have not heard of anyone having any issues with the Airport Extreme Base Station and the MacBook Pro so I am inclined it is not a compatibility problem. Any thought on this issue would be appreciated.

I have both a Linksys WRT54g Wireless Router and a NetGear WGU624 A.B.G Router (set up as AP) on the same network. My CoreDuo MacMini correctly displays the network selections (both 802.11a and 802.11g) and allows you to switch dynamically between the networks. Make sure you have SSIDs set up differently so you can distinguish which is A and G network. Also iStumbler96 is a UniversalBinary and correctly displays all the channel information correctly.
The NetGear supports the Atheros 108Mbps link speed but Apple will only connect at a max of 54 Mbps while PCs with Atheros hardware connect at 108Mbps on both the A and B Network. No utility around yet that lets you unlock the capability to run at 108 Mbps on either the A or G network on the intel macs.
Hopes this clarify.
PS: Apple denies the capability this functionality is there but apparently uses Atheros driver code for OSX which make the process transparent. It is probably more trouble to remove the code than leave it alone. Throughput and range on the A network seems much better, probably because QoS (Quality of Service) is built into the link layer code. You can purchase a compatible NetGear PC card WG511U (A/B/G) tri-mode card and use both on PCs and MACs (PBG4 at present). The only driver available now for 802.11a for MacOSX is from Orangeware ( www.orangeware.com ) and install on a G4 Powerbook, then select A,B, or G networks. Orangeware is working on drivers for the MacBookPro. but you would need a PCI Express card. I don't have a MBP, but I understand that it also uses the Atheros AR5424 miniPCI card just like the intel MacMini, so an external A/B/G card is not necessary.
Net of this story is that, Yes!!!, the intel macs have 802.11 a/b/g support built it and functioning.

Cisco Systems vs "CSIRO" 802.11a and 802.11g infringed upon the '069 patent

Hi,
any news about Cisco Systems and the "CSIRO" 802.11a and 802.11g infringed upon the '069 patent ?
http://www.buffalotech.com/products/wireless/
Dear Customer
As you may be aware, Commonwealth Scientific and Industrial Research Organisation ("CSIRO") sued Buffalo, Inc. and Buffalo Technology (USA), Inc. ("Buffalo"), for alleged infringement of United States Patent No. 5,487,069 ("the '069 patent"). Subsequently, CSIRO also asserted its patent against the entire wireless LAN industry, including, Microsoft, Intel, Accton, SMC and Netgear.
In it's lawsuit against Buffalo, CSIRO claimed certain Buffalo wireless networking products compliant with IEEE standards 802.11a and 802.11g infringed upon the '069 patent. Buffalo believed at that time and continues to believe that there are no grounds for CSIRO's allegations of infringement. The United States district court, however, found Buffalo to infringe the '069 patent and enjoined the importation and sale of Buffalo's IEEE 802.11a and 802.11g compliant products.
CSIRO's lawsuits are against the entire wireless LAN industry and could affect the supply of wireless LAN products by any manufacturer, not just Buffalo. The entire industry is resisting CSIRO's attempts to enjoin the sale of wireless LAN products. Recently, Microsoft, 3COM Corporation, SMC Networks, Accton Technology Corporation, Intel, Atheros Communications, Belkin International, Dell, Hewlett-Packard, Nortel Networks, Nvidia Corporation, Oracle Corporation, SAP AG, Yahoo, Nokia, and the Consumer Electronics Association filed briefs in support of Buffalo's position that injunctive relief is inappropriate in this case.
During the period of time that the injunction is in effect (10/1/2007), Buffalo cannot offer for sale, sell, import, or use its IEEE 802.11a and 802.11g compliant products in the United States. A list of the products covered by the injunction is attached here . The injunction does not prohibit sales of pre-existing inventories of products by Buffalo's customers. In addition, Buffalo has secured CSIRO's agreement to permit the replacement of defective products under warranty. None of Buffalo's other products are currently affected by this injunction.
While Buffalo believes that it will be successful in reversing the district court's decision and will obtain a stay of the injunction pending a decision on the merits, the Court of Appeals has not yet issued a decision. Should the Court of Appeals issue a decision staying the injunction, you will be promptly notified. After the stay is issued or a favorable decision on the merits is obtained, Buffalo will be able to resume the supply of IEEE 802.11a and 802.11g products
Please rest assured that Buffalo continues to stand behind their products and will continue to support all of our loyal customers as it relates to product warranties, technical support and the like without interruption.

I suspect after reading the patent and the litigation that you mentioned above, that the US District Court decision will be reversed as the patent appears to be very vague in its contsruction and verbage. Furthermore, the intent to hold the IEEE hostage on the ratification of 802.11n will not bode well in the court's eyes. If in fact the case is reversed, I believe that the members of CSIRO will be in danger of lost profits litigation from Buffalo. Stay tuned to this bat channel.

Unstable Wireless Bridge Connection via 802.11a(Radio 1) of Aironet 1242

Hi,
I'm going to setup up an AP 1242 in a remote area to support b/g client via a 802.11a bridge link (all using AP 1242).
Before the deployment, I tested the configuration in a lab environment. However, I found the bridge link will come up a while and suddenly gone. Resetting the root AP or the non-root AP cannot bring the connection up again. Sometimes, when I shutdown the b/g radio (radio 0) of the remote AP, the bridge link will be established again. Following is the log from the root AP.
Thanks!

Thanks dmantill for reminding me to revisit the antenna and related stuff.
As the setup is in a lab environment, the APs are put on a work bench next to each other, therefore, the radio output power was lowered.
After adjusting the output powers, it works as expected.
Thanks Surendra and dmantill.

Does photosmart d110a have 802.11a? If not, does it have 802.11n?

Had it connected via b/g WiFi but it doesnt seem to connect with my new router even though ive checked all settings. The manual and cd are useless, and hp site's specs for this photosmart are useless. Appreciate your help if you can find out if it's 802.11a or n compatible.

Hi,
Did you ask this question yesterday ? Your printer is NOT networkable without buying more hardware:
The following table lists connectivity options.

WLAN showing up as 802.11a/g but not 11n

Using a wifi scanner like Metageek inssider or chanalyser, I'm seeing one of our WLANs as only 802.11a or g but not 802.11n like it should be.
All the other SSIDs on that AP/controller are showing as 802.11n. I can't for the life of me think how this could be, but the scanner is showing the top data rate as 54Mbps. Connect to another SSID and it shows the upper data rates as well.
Any ideas why this would be? Typically this just happens to be our main SSID. Is it just the scanner interpreting things wrong? I've looked at the controller and the upper data rates are enabled for 802.11n as well as 40MHz for the 5GHz radio.

It's WPA2/AES but WMM is not allowed (Cisco TAC had me remove that option to resolve a bug).

WiSM2 WLC 7.2 Maximum Allowed Clients under Global Parameters 802.11a/n b/g/n

Hello everyone,
Just loaded the 7.2.103.0 software onto the brand new WiSM2. Going throught the options and have found that under the global parameters for 802.11a/n, 802.11b/g/n radios is now the "Maximum Allowed Clients" option. The allowed setting is from 1 - 200 clients.
Does that mean only 200 clients will be allowed to associate to the WLC on that radio at a maximum?
Doesn't seems to make sense... I have the 500 AP license on this WiSM2... I know this option used to be an optional setting under a WLAN in previous releases.
Any ideas?
Regards,
Sasha.

Does that mean only 200 clients will be allowed to associate to the WLC on that radio at a maximum?
As what Scott has responded, this means 200 clients per WAP.
If you do exceed 200 clients per WAP (or whatever value you put in there) the clients will just get a nag and the system will let you in eventually.

AP1042 802.11a/n/ac Radios down in the controller

802.11b/g/n Radios is up but 8021.11a/n/ac radio is down.   802.11a netowrk status is already enabled. Not too sure what may most likely be causing it to down?
Below is the output of "show sysinfo" from the controller and "show version" from the AP
Any input is appreciated.

This is the reason why your AP's 802.11a radio is permanently disabled. Unfortunately, the Wireless LAN Compliance Status (06 October 2014) doesn't list old-model APs. And this doesn't help anyone.
You may need to contact your vendor and ask them politely if it's possible for you to replace your AP with the ones with the correct Regulatory Domain.

Roaming between 802.11a & g

Hi forum,
Can wireless clients roam seamlessly between 802.11a and 802.11g APs? they will be using the same SSID.
besides, if I select different channel for bluetooth clients, can it coexist with 802.11g?
Thank you,
paul

It is possible for a wireless client to roam between 802.11a and 802.11g.

EA4500 - MBP Problem 802.11N / 802.11A

Hi Guys,
I've been using the EA4500 for almost a month now and I'm loving it. Fast & stable, but I noticed one problem. My Macbook Pro is not connecting via 802.11N but instead it is using the 802.11A.
screencapture:
I tried trouble shooting this by using my other router Linksys WRTt310n and I noticed that my MBP is conencting to the 802.11n. So basically it's not the an APPLE or MBP problem.
Is there any setting I should be checking out?
Thank you very much in advance.
PARC
Solved!

Hi hiptechboy,
You just made my day! after setting up the QoS and turning on the WMM. Look what just happened...
Thank you very much mate! But can you please explain what does WMM got to do with my connection problem with the 802.11N network?
Thank you very much again guys!
Parc

Prefer 802.11a over 802.11g within SSID - Is it possible?

Currently have a corporate SSID advertised enabling clients to connect using either A or G. Ideally I'd like clients too connect using A if they're able, and if not connect on G.
I think I've read on these forums this is possible but requires the WLCs to be running specific (quite new) firmware.
Is anyone able to advise?
TIA

Yes, you can try to make 802.11a more attractive by tweaking the rrm values on the controllers.
For example:
my tpc values for a are:
Tx Power Level Assignment Algorithm
Power Threshold (-80 to -50 dBM) -67
and only have 36, 40, 44, 48, 149, 153, 157, 161, 165, 26 channels enabled
for b:
Tx Power Level Assignment Algorithm
Power Threshold (-80 to -50 dBM) -70
You can also choke back on the basic rates for b/g depending upon your density.
If your environment allows you to control the clients, you can also tweak the network card settings on the clients to prefer a as well.

Can you disable 802.11g and 802.11a on an Airport Card?

Does anyone know if there is a way to disable 802.11a and 802.11g functionality on a MacBook Airport card? I have a very old 802.11b access point and the airport card seems to be making it fail. I was hoping that by turning off 802.11g or potentially adjusting some other airport parameters I might be able to keep the AP from crashing. I'm hoping to keep the AP I have because it has an integrated print server which has been great. If there is no way to modify the settings on the airport card, I guess I'll need to upgrade my AP.
Thanks.

Well, I should have used the advice I give to everyone else. Even though my wireless router is very old, there was a firmware upgrade for it. Even though the release notes for the firmware said nothing about it fixing a problem with a MacBook, I upgraded to the latest firmware. After a week or so of testing, it seems to have resolved the problem with the AP going dead when the MacBook was using it.

Prefer 802.11a over 802.11g

Hello,
Is there a way in an autonomous AP to set 802.11a/5ghz as the prefered connection frequency if the client is 802.11a capable? We have a number of notebooks that have draft N cards and we have AP's with A and G radios and I wanted to force the A capable clients to connect via A instead of G.
Thanks,
Dan.

Unrelated to the band-select CLI command, I am using a GPO with 2 x SSIDs - SSID2.4 & SSID5. The SSID5 has higher priority and from my limited testing, N clients seem to connect to to the SSID5 and obviously G clients only see SSID2.4 and connect to that. It seems to be working so far.
Obviously you need to be running the WZC supplicant for this to work.
Modifying the driver band-select option isn't a great option as not all clients support it and it is not scalable in any enterprise deployment. Scripting those drivers modifications would probably be a nightmare. I guess it may work in a small environment.
We'll see how well the band-select CLI option works.

802.11a Mesh Outdoors with 5500 controller

Hi
I am working on a project that will involve 5500 controllers managing 1260 series N rate A/Ps. There may be a requirement for MESH but my previous experience using Motorola 802.11a radios is that random, intermittent radio detections resulted in the MESH network having to keep re-forming resulting in less than 100% availability.
What's peoples experience in the UK is 802.11a outdoors?
Ideally i would prefer to use 2.4GHz and repeater access points for those areas not serviced with data connection but I cant find any info' so far on how whether the 5500 controller is able to manage repeater access points.
Any guidance or experiences much appreciated
Steve

I don't live or have done work in the UK so can't answer your first question, but for your other question... The wlc does not manage any APs configured as a repeater.
