RE: [EXTERNAL] Re: [WIRELESS-LAN] Client roaming

We design to -60dBm as measured by a Fluke Aircheck, That usually works out to around -63 to -65 on a MacBook and -65 to -68 on a tablet or phone. I’m sure there are a few outlier devices that measure it as weaker than -70, but until recently it was clear that those were outliers. If you did

Re: [EXTERNAL] Re: [WIRELESS-LAN] Client roaming

Agreed, an iOS device at -65 starts roaming and acts wonky from time to time. The issue we run into a lot is, which iOS device do you design for? Do you design with the iphone 11 or 10, or do you design for the frst SE, 6, or 7 that are four or five years old now? With iOS devices able to

RE: [WIRELESS-LAN] Client roaming

While this is not an Apple specific thread, Dan Jones’ presentation at Wireless Technology Forum on “Designing Wireless Networks for Apple” was very entertaining/helpful in explaining the Apple roaming docs he referenced. Several pointed out documented vs observed behaviors are not always the

Re: [WIRELESS-LAN] Client roaming

On thing to keep in mind is that iOS devices start behavior poorly when they have no good option above -65. That’s the threshold they prefer 5GHz and when you combine that with “hallway design” and “band select” you are asking for a bad time. Scenario: Client doesn’t see 5GHz above -65.

Re: [WIRELESS-LAN] Client roaming

Best thing you can do for clients is have a 5GHz only SSID. We moved over the summer to this with our main 802.1x network and it has fixed a ton of these roaming issues and complaints of performance. Basically take the decision making out of the hands of the client, give them only one band to

Re: [WIRELESS-LAN] Client roaming

We are seeing a lot of this on the 1815w’s. We are getting complaints in dorms that have 9115s and 2802s as well. I am going to fix the building with the 2802s tomorrow to see if that helps them any. Same thing we get 1 complaint, but everybody on the floor is having the issue. I am not

RE: [WIRELESS-LAN] Client roaming

A lot of devices roam aggressively once RSSI falls below some threshold level. It was -70dBm for a few years. It started on Apple products and was soon copied by Samsung, Microsoft, and many others. I’ve long treated roaming issues where the 5GHz signal is around or weaker than -70 as

RE: [WIRELESS-LAN] [External Email] Re: [WIRELESS-LAN] Transitioning from older controller to new controller

The 9800 does have a conversion tool for the aireOS controller configs and does most everything but the encrypted stuff. Even if building from scratch, running the existing config through the tool may help in understanding how all the pieces work, including the equivalent commands between the

We're getting hit with this too, and have a case open with Cisco on it. Next step is to set up some live debugging... We have two 8510's paired for failover, upwards of 3,000 client wi-fi devices connected, and we've had maybe 20-30 reports that might be related to this. We may have clients who

RE: Client roaming

My personal belief is that even today, technologies like band select just compete with the secret sauce on the client side, and are subject to problems. Every time I've experimented with it, I turn it back off (cisco and aruba), as your success is often short-lived until the next device OS or

RE: [WIRELESS-LAN] Client roaming

FWIW, I've been reluctant to assume this is a new problem. Usage patterns have changed in the dorms and people are spending much more time using real-time protocols than ever before. Those protocols make brief connectivity issues very noticeable. It's quite possible we've always had these

Client roaming

Wondering if anybody else is seeing this. We currently have devices doing a lot of roaming between 5 and 2.4 radios, especially in the dorms. I would not think anything of it normally, but they are moving from a -52 to -58 on the 5 radio to a -75 or worse on the 2.4 radio. This doesn’t seem
