iPad WIFI - Jitter & latency problems

Installing and Using OpenWrt
1

Hi,

I need help trying to iron out flaws in our WIFI..

Lately I have been getting bad latency spikes on our WIFI 5GHZ specifically on our iPad PRO. The iPad drops out in the middle of playing online games or gets random stutters. Gaming on our other devices is impeccable.

The iPad PRO didn't have these issues before as far as I know. Distance to the AP doesn't seem to matter when it spikes.

The connection is fiber 100/100. On the computer connected to the Dumb AP with a cable. I consistently get A+ with low latency on Waveform.

On our 5GHZ WIFI Waveform gives a A+ rating on Android devices, but only sometimes on the iPad PRO.

I have tried different settings for the SQM-QoS, for packet steering and Flow offloading.

Fujitsu S920 settings: (ROUTER)
SQM QoS installed, ingress/egress = 90/90, running Cake, piece of cake.qos, Overhead 44.
Packet Steering is enabled
Flow offloading is disabled

Archer C7 v2 (DUMB AP):
Packet Steering is enabled
Flow offloading is disabled
ath10k-smallbuffers

The Archer c7 v2 has an QCA9880 and support TXQS/ATF/AQL.

Is there something I can try to remedy these issues with the iPads bad jitter and latency?

Best regards.

You have to disable apple wifi location service.

Thank you for the suggestion. I have now disabled the setting. I will test the iPad to see if the issues have been resolved.

Sadly it doesn't seem do have improved at all.

If other devices perform well under same conditions the problem is the client device. Sometimes windows plays bad tricks, when linux on same hardware gets ideal wifi and vice versa.

What do you mean? The iPad has bad WIFI regardless if the PC is on or off.

However, something must have changed. I remember setting up Openwrt and QoS and the WiFi a few years ago and then even the iPad received the best rating possible on DSL-Reports.

These are not the same.

There are some things iOS does not play nice with.
