Re: [WIRELESS-LAN] Disabling 802.11b speeds
Hi, To resurrect an old thread, we've run into an incompatibility that affects all Realtek chipsets (other than the 8188CE with latest drivers dated March 2013) which do not associate if we have 802.11b data rates present (mandatory or supported) but not ALL of them. So, 1/2/5.5/11 enabled = works 11Mbit mandatory, all other 802.11b rates disabled (12Mbit/sec+ set to supported) = fail. The 8188CE driver update released this March resolves the issue with the 8188CE but other Realtek chipset users are out of luck. We're looking at disabling 802.11b entirely as this also resolves the issue. The workaround on the device configuration with this RF profile present is to set the Realtek NIC to do 802.11b only. For some reason, this works! Has anybody else run into this issue?

Unless something has changed then I understand this is the way to do it if you intend to use Band Select, as Band Select makes it mandatory for all bands/Radio Policies to be enabled. So you enable all Radio Policies (inc .11b), but disable the .11b speeds. From the footnotes of WLAN 'SSID Name' Advanced on the controller management GUI. 8.

Re: [WIRELESS-LAN] Disabling 802.11b speeds
We too were thinking of disabling the B rates. But I read (post below) that some people run into Apple devices dropping connection when they did this so I am still looking at this. Post: If you're using Cisco one thing to check is that the MCS0 data rate is enabled. I had a lot of problems with Macs and iThings dropping after I disabled the 802.11b rates and MCS0. Per TAC's suggestion I re-enabled the MCS0 rate and have not been experiencing the problems since. Apparently it has to do with the OS dropping the data rate to MCS0 to save power, but not checking if that rate is supported before doing it.

SV: [WIRELESS-LAN] Disabling 802.11b speeds
Hi Todd, Disabling 802.11b is not an option but a must nowadays. You get much better overall performance with all data traffic over OFDM. There's a lot of time (Airtime)that gets lot if you allow old legacy protocols. We have had 802.11b off for over a year and nobody complains.

RE: [WIRELESS-LAN] Disabling 802.11b speeds
We've eliminated all the b rates on our wireless with no significant issues. We had lots of connections to our wireless at 802.11b rates, but it was users out of range from the APs, or clients with outdated drivers - both problems which were easily corrected. Our wireless is entirely 1X, so consumer devices like TVs and game consoles, some of which I've heard require at least the 11Mb rate, were not a concern here because they couldn't authenticate anyway.

RE: [WIRELESS-LAN] Disabling 802.11b speeds
Forgot to mention, if you run Aruba (and I'm sure many others support a similar feature), you can check a flag called Broadcast/Multicast Optimization and even when leaving b rates on, broadcast and multicast won't be sent at the lowest basic rate, but the minimum supported rate by the stations connected to a particular AP (so the AP keeps track of the stations connected to him and what is the lowest rate they can do).

RE: [WIRELESS-LAN] Disabling 802.11b speeds
We turned off all B rates this summer along with 802.11b protection (we are an Aruba campus). We did it during the summer and saw immediate improvements in speed. To be effective, you need all B rates off, the goal isn't to kill the lower speeds, the goal is to kill B altogether. It's an older and less efficient protocol. Part of the reason for the increase of speed even during the quiet time of summer is that the AP's will use the lower speeds 1Mps/2Mps for management / broadcasting / Beacons / etc. By dropping B, the slowest speed is now 6 Mbps for all the base level management traffic, etc. No complaints so far, we have both open and wpa2 and all sorts of devices. Stats from last semester showed almost no B usage, so we felt pretty safe in shutting it down. I have heard that the Wii's want B/1Mbps to find the AP and then can ramp up, but haven't confirmed / seen this yet.

Re: [WIRELESS-LAN] Disabling 802.11b speeds
We dropped 802.11b this time last year. I haven't received one complaint, and the performance increase was dramatic. Your mileage may vary, but I found that APs would go into b/g protection mode if they thought an 11b client might be around. What resulted was a situation where about half of our APs were in protection mode at any given time, even though not a single 802.11b client was connected. - Craig SFU SIMON FRASER UNIVERSITY Network Services Craig Simons Network and Systems Administrator Phone: 778-782-8036 Cell: 604-649-7977 Email: craigsim...@sfu.ca Twitter: simonscraig - Original Message - From: Todd M.

FYI- Ticketmaster has a new Janam dual-band scanner that does nicely on 5 GHz in my testing.

The issue with the Wii is true here is article describing the issue. We have had a few complaints in the residence halls regarding the Wii. For those folks we just educate them to get a wired lan adapter for their Wii system. The only place we had to keep b data rates was for ticketmaster scanners at our stadiums using rf profiles in 7.2 code helped us localize these data rates to only those aps. http://nostringsattachedshow.com/2012/01/18/nintendo-vs-cisco/ Thanks Trent -Original Message- From: The EDUCAUSE Wireless Issues Constituent Group Listserv [mailto:WIRELESS-LAN@LISTSERV.EDUCAUSE.EDU] On Behalf Of Oakes, Carl W Sent: Thursday, September 27, 2012 11:50 AM To: WIRELESS-LAN@LISTSERV.EDUCAUSE.EDU Subject: Re: [WIRELESS-LAN] Disabling 802.11b speeds We turned off all B rates this summer along with 802.11b protection (we are an Aruba campus). We did it during the summer and saw immediate improvements in speed. To be effective, you need all B rates off, the goal isn't to kill the lower speeds, the goal is to kill B altogether. It's an older and less efficient protocol. Part of the reason for the increase of speed even during the quiet time of summer is that the AP's will use the lower speeds 1Mps/2Mps for management / broadcasting / Beacons / etc. By dropping B, the slowest speed is now 6 Mbps for all the base level management traffic, etc. No complaints so far, we have both open and wpa2 and all sorts of devices. Stats from last semester showed almost no B usage, so we felt pretty safe in shutting it down. I have heard that the Wii's want B/1Mbps to find the AP and then can ramp up, but haven't confirmed / seen this yet.

Re: [WIRELESS-LAN] Disabling 802.11b speeds
When I disabled the lower rates it broke the wii. That was last year so maybe the wii has improved. I re-enabled 1,2 and the wii started working. On Thu, Sep 27, 2012 at 8:54 AM, Todd M.
