RE: Turning off 2.4 on a select SSID?

Here at the Charleston Area Medical Center, we are moving to an 802.11ac Wave 2 rollout and due to the density requirements, (2 AP coverage at -63dbm, 3rd AP at -70) DFS on 5 GHz is mandatory. We were an early adopter of 802.11a and still have some 11a clients around that may or may not

RE: [WIRELESS-LAN] Turning off 2.4 on a select SSID?

I haven’t read the whole thread, but just in case this wasn’t mentioned, DFS channels factor into this decision. Some clients don’t support any or all DFS channels. If those can fail over to 2.4, then DFS channel use if very practical. If they can’t, you must be far more discriminate with

We're also seeing a 50-50 split as far as associations go, but for actual usage (based on data transferred), things do look a bit more promising. Associations: - 51% @ 5GHz (32% .11n, 17% .11ac, 2% .11a) - 49% @ 2.4GHz (36% .11n, 13% .11g) Usage (Data Transferred): - 66% @ 5GHz (34% .11n, 32%

RE: Turning off 2.4 on a select SSID?

A separate 5-Gig SSID might work now, but we had issues back in 2009. We had a 5-Gig only 802.11n SSID that supported IPTV Multicast. We then got complaints from all those with b/g/n clients so we retired that SSID. ​ Bruce Osborne Wireless Engineer IT Network Services - Wireless (434)

Re: [WIRELESS-LAN] Turning off 2.4 on a select SSID?

In my poking around, if a device says "B,G,N" it's always been 2.4GHz only, "A,B,G,N" or anything saying "AC" is safely dual-band. Of course, if it doesn't even say THAT much I'm not sure I'd want to buy it… :) -Chris == Chris Murphy Business

RE: [WIRELESS-LAN] Turning off 2.4 on a select SSID?

That's a good point Phillipe. Had to recently shop for a laptop for a relative to use at school. Had to open up Device Manager to find the wireless card description. It appears that at about the $400 price point is the split between single band and dual band wireless cards. Mearl Sent from

Re: [WIRELESS-LAN] Turning off 2.4 on a select SSID?

My experience with Mac OS is that while you may start out on 2.4, it will move itself to 5 given a bit of time – that’s assuming the vendor-specific band/ap-steering isn’t mucking with it, and the 5 radio is running in 40-wide. I see this when students roll into the residence halls after

Re: [WIRELESS-LAN] Turning off 2.4 on a select SSID?

Chris, The Wi-Fi deployment is definitely a big part of the equation but so it the “sticky client”. I’m writing this email just above a nice dual band Access-Point with an observed RSSI of -55dBm on my Macbook Pro, and I’m on 2.4 GHz :( (I started my journey far away from that same AP…)

Re: [WIRELESS-LAN] Turning off 2.4 on a select SSID?

I would add that band selection is far more complicated when a device is moving then when stationary. In the case of some mobile devices, they will prefer a 2.4 anchor just to lesson the number of times they have to roam re-associate i.e. Maintain that WiFi call. Jeff From:

Re: [WIRELESS-LAN] Turning off 2.4 on a select SSID?

Well, we went to eduroam as our primary last fall. There are many clients that don't support advanced EAP types, so we removed our duplicative EAP-tls SSID leaving 3 major SSIDs. Eduroam, UNC-psk and our onboarding SSID. Ryan Turner Senior Network Engineer, ITS The University of North

Re: [WIRELESS-LAN] Turning off 2.4 on a select SSID?

On the eduroam question, our consortium think at this point is to abandon our “branded” SSID in favor of eduroam. I’ve yet to find a compelling technical reason to continue support of a branded SSID in addition to eduroam, so it sort of forces the need to continue support of both 2.4 and 5 –

Re: [WIRELESS-LAN] Turning off 2.4 on a select SSID?

According to our management console, on our campus more than 11% of client stations are 2.4GHz capable only, and incapable of 5GHz. -- Jason Trinklein Wireless Engineering Manager College of Charleston 81 St. Philip Street | Office 311D | Charleston, SC 29403

RE: [WIRELESS-LAN] Turning off 2.4 on a select SSID?

Phillipe, I would suggest that it’s not always an issue of the client not supporting 5ghz, but rather that some deployments are not conducive to good 5ghz propagation – we’ve all seen WAPs in hallways between classrooms before. In my experience, clients that associate to 2.4ghz are doing so

Re: [WIRELESS-LAN] Turning off 2.4 on a select SSID?

My ears have been burning… I understand Hector's comment about the spirit of eduroam, but like Ryan I have also be tempted in the past to only support 5 GHz in certain areas because 2.4 GHz was becoming too much of a pain (e.g. Dormitories). The eduroam Compliance Statement requires 802.11, no

Re: [WIRELESS-LAN] Turning off 2.4 on a select SSID?

I’ve yet to see anyone in EDU approach seamless 5 coverage, and looking at a report of current 2.4/5 client anchoring won’t tell the whole story. You’d need to focus more on association reports to see what percentage of time a client is on 2.4 vs 5 over a wide time period. In one of our

RE: [WIRELESS-LAN] Turning off 2.4 on a select SSID?

We’re a fairly small campus, but we have almost a 50/50 split: na – 34% ng – 24% a - 22% g – 20% so that gives 56% on 5GHz and 44% on 2.4GHz. Thomas Carter Network & Operations Manager Austin College From: The EDUCAUSE Wireless Issues Constituent Group Listserv

RE: [WIRELESS-LAN] Turning off 2.4 on a select SSID?

I would go back to Jason's comment and reference eduroam's policy. I personally think that only allowing 5GHz on eduroam goes against the spirit the global availability of eduroam. My 2 cents. Hector Rios Louisiana State University -Original Message- From: The EDUCAUSE Wireless Issues

Re: [WIRELESS-LAN] backhaul wifi comparison/suggestions

A couple suggestions on using low end devices for PTP. These are directed at the UBNT line specifically, but are probably good advice for most outdoor installs. Keep a spare. Cheap doesn't happen by chance. My experience with UBNT is that the cheaper the product, the higher the likely hood

RE: [WIRELESS-LAN] Turning off 2.4 on a select SSID?

As I am approaching the problem, I think there is a middle ground… The middle ground is you elevate one SSID to 5 Gig only, and have a secondary SSID as 2.4. In our situation, it would mean eduroam would be 5 and UNC-PSK would be 2.4 and 5. It creates an incentive for individuals to upgrade

We are seeing the same, about 50/50 I would argue you are not going to turn off 2.4GHZ for a very long time. It will take a while to get all clients over to 5 GHZ.I see 2.4ghz becoming the place we put all the "Low bandwidth Non traditional" stuff. You can leave your HVAC, Cameras,

RE: [WIRELESS-LAN] Turning off 2.4 on a select SSID?

We offer 2.4 and 5 GHz service. When we have conflicts, we work with departments to give them a channel in the 2.4 GHz space, then we take that channel out of our central infrastructure. So, for example we gave engineering channel 6 for all of their labs, and we took that out of our central

Re: [WIRELESS-LAN] Turning off 2.4 on a select SSID?

RE: [WIRELESS-LAN] Turning off 2.4 on a select SSID?

What we are going to do is a test in one of our IT building of 5 GHz only wifi on eduroam. We ran a report, and we are seeing about 25% of the connections running on 2.4. We don’t know how many of these are a result of the failure to band steer, or if the devices are just not 5 gig capable.

RE: [WIRELESS-LAN] Turning off 2.4 on a select SSID?

I guess this brings up another good question, and that is, what is the percentage of 5GHz vs 2.4GHz you all see in your institutions? For us is still 50-50. And it’s been like that for a while. I still see new laptops that only come with 2.4GHz adapters. I would love to start turning off

RE: [WIRELESS-LAN] Turning off 2.4 on a select SSID?

Kees, I think your skepticism is well founded. We have many locations with multiple 5ghz radios in the same room, but multiple 5ghz on the same device will be a more “uncharted” territory for our deployment. I am in the process of getting a few AP250 to throw into a few of our smaller
