I have two AP11D routers with a wired connection between them. When I am streaming a video from an iPhone device and move from one are of the house to another, the device often freezes as it is still connected to the router which now has a lower signal. I fix this by toggling wifi on the phone.This wasn't really the user experience I was hoping for, is there anything that can be done to help? Is there anything that allows the device to handover between the routers, kind of like what happens in a cellular network?Thanks
Hi David,It's likely that the placement of your APs are too far from each other, or the transmit power, channel width are imbalanced.
The client devices (phone, laptop, etc) choose when to roam from AP to AP. While there can be some software magic built-into the AP controller software, it often does a lacklustre job.
The best way to help devices roam effectively is through good design. That can be very challenging in a house, where your options are so limited. You want the "cells" of coverage to overlap, but not too strongly. You also do t want them to be too weak. Ideally as the signal from AP1 starts to diminish, the Signal from AP2 starts to get much stronger. This allows your device to start the process of searching and acquiring a new AP to associate with.
What do you think is your scenario? Are the APs too far apart (too weak a signal from one to the other)? Or are the APs too close? (Try lowering the signal).Also, are your SSIDs 2.4 & 5GHz combined or separated out?
As mentioned previously, it's not the APs that notify the client device to roam; it's the other way around.
The APs have an "offer" beacon, but it's the client device that chooses when and where to roam based on the environment it is in and it inherent algorithms. This is the basis of how WiFi works, it's not an "aruba thing".
A faulty AP could impact that, but it's most likely poor WiFi design that's the impacting factor.
Thank you everyone for your contributions. This is a concrete, two story house. There is a large opening for the stairwell and the routers essentially sit on top of each other near this opening. I think likely the signal is too strong from what I am reading. I have the default settings enabled, so I will try what was recommended above.I have two SSIDs. One of them is a combined 2.5/5 GHz network, the other is only 5 GHz. I typically try to stay on the 5GHz.I have not had a chance to experiment with any changes yet, but will get back to you if I find something that works better. (Do you know where the configuration is for not accepting weak signal clients?Thanks,
That's a good question David! Hopefully someone with more insight can chime in.
Im guilty of having not really tested the behaviour…. Typically we find the right level and leave it static. I can say that I once tried to leave a "range" on an AP17 and it always seemed to default to the lowest power, leaving clients starved for signal. This was two updates ago though, so it may have changed. I'd try setting a static power level - start with High, and step back from there. Test, test, test.
