I have 7 acces point sophos and when my users changed place , the iphone keep the old AP and by consequent the wifi is slow and stop few minutes laters.
they have to switch off / switch on WIFI in order to connect to the near AP.
Whereas with my Huawei phone, there is no probleme ! it switched to the new AP in few second..
All AP and controler are up to date.
Any ideas please ?
Thank you for contacting the Sophos Community.
This is a common issue with iPhones and Tablets dues to them "hanging" to the original AP that they connected to.
Take a look at this document on Wireless Roaming for Enterprise from apple.
To what Sophos product are you connecting the APs and what version is it running?
The product we are using is the Sophos XG105 (FOS 17.5.15 MR-15) and products connected to APs are iPhone 7/8/11 last iOs update
I read your document but what can you suggest ?
Try reducing the AP TX power.
Make sure Fast Transition is enabled. WPA2 supports IEEE 802.11r which is the standard for the Fast Transition.
What type of AP are you using?
