Location of wifi connection logs
Hi all,we have multiple wifi networks in our office.We have troubles with an iPad which constantly connects to a wifi network with bad wifi signal although there is another network available with much better signal.I wonder if there are any wifi connection logs available in iOS which indicate WHY the iPad connects to the network with less signal strength.I inspected the device's logs via Xcode but didn't find anything helpful.Does anybody know if those logs exist and how they can be read? Easiest way would be to read the logs from a device backup.Regards

Understanding iOS Wifi Logging
Hi all,in order to debug Wifi issues, I took a recording of the wifi logging as described here.As a device I used an iPhone 11 Pro.What makes me wonder is that there are entries where the iPhone seems not to receive any signal from the network.5/10/2020 18:55:07.714 CurrentBSS {Praxis RB88 - 44:4e:6d:18:b1:76} {-70dbm, 1, 2848646ms } RoamCache - {}05/10/2020 18:55:07.714 __WiFiLQAMgrLogStats(Praxis RB88:Stationary): Rssi: -70 {-70 -75} Snr: 21 Cca: 28 TxPer: 0.0% (5) BcnPer: 0.0% (49, 53.1%) RxFrms: 12 RxRetryFrames: 1 TxRate: 585000 RxRate: 520000 FBRate: 175500 TxFwFrms: 8 TxFwFail: 0 TxReTrans: 0 time: 3713.3secs fgApp: (null)05/10/2020 18:55:07.715 WiFiLQAMgrCopyCoalescedUndispatchedLQMEvent: Rssi: -70 Snr:21 Cca: 28 TxFrames: 5 TxFail: 0 BcnRx: 49 BcnSch: 49 RxFrames: 12 RxRetries: 1 TxRate: 585000 RxRate: 520000 FBRate: 175500 TxFwFrms: 8 TxFwFail:0 TxRetries: 0...05/10/2020 18:57:09.702 __WiFiLQAMgrLogStats(Praxis RB88:Stationary): Rssi: 0 {0 0} Snr: 0 Cca: 6 (S:0 O:6 I:0) TxPer: 0.0% (0) BcnPer: 0.0% (0, 53.0%) RxFrms: 0 RxRetryFrames: 0 TxRate: 0 RxRate: 0 FBRate: 0 TxFwFrms: 0 TxFwFail: 0 TxReTrans: 0 time: 3835.3secs fgApp: (null)05/10/2020 18:57:09.702 WiFiLQAMgrCopyCoalescedUndispatchedLQMEvent: Rssi: 0 Snr:(null) Cca: 6 TxFrames: 0 TxFail: 0 BcnRx: (null) BcnSch: (null) RxFrames: 0 RxRetries: 0 TxRate: 0 RxRate: 0 FBRate: 0 TxFwFrms: (null) TxFwFail:(null) TxRetries: 0...05/10/2020 18:57:09.798 WiFiLQAMgrCopyCoalescedUndispatchedLQMEvent: Rssi: -71 Snr:19 Cca: 6 TxFrames: 0 TxFail: 0 BcnRx: (null) BcnSch: (null) RxFrames: 0 RxRetries: 0 TxRate: 0 RxRate: 0 FBRate: 0 TxFwFrms: (null) TxFwFail:(null) TxRetries: 0...05/10/2020 18:57:14.638 CurrentBSS {Praxis RB88 - 44:4e:6d:18:b1:76} {-59dbm, 1, 2975569ms } RoamCache - {}05/10/2020 18:57:14.638 WiFiLQAMgrCopyCoalescedUndispatchedLQMEvent: Rssi: -59 Snr:21 Cca: 8 TxFrames: 103 TxFail: 0 BcnRx: 213 BcnSch: 217 RxFrames: 121 RxRetries: 8 TxRate: 650000 RxRate: 585000 FBRate: 175500 TxFwFrms: 111 TxFwFail:1 TxRetries: 4505/10/2020 18:57:15.089 __WiFiLQAMgrLogStats(Praxis RB88:Stationary): Rssi: -72 {-69 -73} Snr: 21 Cca: 8 (S:4 O:3 I:1) TxPer: 0.0% (103) BcnPer: 1.8% (217, 53.0%) RxFrms: 121 RxRetryFrames: 8 TxRate: 650000 RxRate: 585000 FBRate: 175500 TxFwFrms: 111 TxFwFail: 1 TxReTrans: 45 time: 3840.7secs fgApp: com.apple.Preferences05/10/2020 18:57:15.090 WiFiLQAMgrCopyCoalescedUndispatchedLQMEvent: Rssi: -72 Snr:21 Cca: 8 TxFrames: 103 TxFail: 0 BcnRx: 213 BcnSch: 217 RxFrames: 121 RxRetries: 8 TxRate: 650000 RxRate: 585000 FBRate: 175500 TxFwFrms: 111 TxFwFail:1 TxRetries: 45Do I read the logs correctly? Does this mean at 05/10/2020 18:57:09.702 the device did not receive anything from the wifi network? Does this indicate any transmission issues in the network or is it nothing to worry about?Regards

Unterstanding MacOS wifi logs
I'm using a Macbook Pro mid 2014 (Big Sur) and try to investigate wifi connection problems. My router (Fritz!Box 7590) shows in the logs that constantly every 10 minutes the Macbook has been logged of from the wifi network (802.11ac) and logged on again. E.g. it shows that at 10:04:30 the device has been logged off and then at 10:04:34 logged on again. I turned on wifi logging on my Macbook: wifi.log - https://developer.apple.com/forums/content/attachment/af953247-3676-411e-a4d8-24400ef31f5d Unfortunately I don't understand the contents of the wifi.log. May anybody give me a hint if there are specific log messages that indicate the reason for logging off and logging on again? Best regards
