So it is nothing new that Apple’s wifi hardware is full of headaches… I had a user lose 80Mbps of download speed from his fucking Apple Bluetooth keyboard causing interference… now I’ve got a really confusing one
In a deployment with three UAPs, iOS devices (new or not) experience up to 3-10 seconds of packet loss intermittently and latency from 30ms-1s between my laptop and any iOS device on the network regardless of location. I have ruled out interference I think. Samsung phones and my laptop all have <3ms latency between any AP, my router, and 20ms to the Interwebz. I had bandwidth issues before with Apple devices that were resolved by changing the channel width to HT20 for 2.4G and VHT20 for 5G. Doing that here seems to have had some effect on packet loss, along with lowering the transmit power, I am only dropping one or two every 1-2 mins. But the jitter is still the same. Things are now functional, but this worries me… I would like to know what the fucking deal is with these Apple radios
Nobody on the UBNT forums has a real answer and there are several long threads about it. It is honestly rare to have someone super knowledgeable chime in there without waiting 6 months. I can’t just tell people not to use Apple… though I wish I could
There is an option in unifi controller settings for the uap. I believe it is low power mode. Turn that off. Apparently Apples implementation is not in spec so it does not play nicely with unifi products
Same issue in my office with just one older UAP. Co-workers S9 works fine, bosses iPhone X works fine, but my iPhone 7 drops. Sometimes 2s latency.
Are Apple fucking retards? I get that it’s in their interest for you to be in their ecosystem, but the problem is people leave their damn houses! I left Android for the 7 but I am definitely never buying another Apple product. The whole ease of use thing doesn’t hold up at all anymore…
yea it is that one i guess you may have another problem. If that was unchecked by default. I have not looked too far into it but see if turning off low power mode on the iphone helps
Nope. Basically had the iPhone and iPad stuck to the AP at different points during testing.
Now at my office, with an older AP, turning the 5G channel width the HT20 from HT40 seems to have fixed the issue at least here. But at the original site I was troubleshooting there was only the option for “VHT.” Dunno what that means. My latency is a lot lower in my office now but I’m still getting long periods of drops.
Will do, next time I’m on site. The setup is more complicated than I described, but the jist is the same. I actually have one AP in the ceiling close to an exterior wall for the “Beer Garden” and it is dedicated to servicing the POS iPads that the waitresses use outside. Connecting my laptop to it, or connecting to the iPads to the main guest network yields the same results either way. UniFi is not reporting much interference, and while I’m not an expert on the physics of WiFi the results from my laptop tell me that this is some sort of software bug
I am thinking with the LR that you may just have an anomaly of the three and apple devices trying to jump between them and something is not working out very well in the interim. That may be the packet drops and such. Also I assume there is only one ssid and channel you are using for these apple products to connect to? Reason I ask is that if you have same ssid on both 2.4 and 5ghz they may be blindly jumping between those two for some weird reason
Maybe that’s it. I think I am losing my mind at this point, that makes sense but on site yesterday I disabled the 2.4G and 5G and tested both one at a time, didn’t seem to do much. Let me try that in my office with just one AP. The SSID for the iPads is only being broadcast off that one AP though
