I'm having frequent disconnections on my work laptop connected to the flint 3’s main wifi. The laptop (running Win11) does not effectively lose the connection, I notice It because during Teams calls I frequently have 1-to-2 seconds of hold for missing connection. In these moments, I check the signal in the radar icon bottom left and see It has be come weaker all of a sudden.
It’s quite annoying and would like to understand if it’s a common issue or not, and in case how to troubleshoot It.
Running last Fw, I don’t have any particular configuration on my main wireless lan, Classic config by default. I have then a secondary wireless lan per IoT and have split my 4 lan ports into two different VLANs, but this has nothing to cope with the issue I’m facing.
Edit: forgot to Say the notebook works regularly on several WiFi I use at work, on customer premises, etc. Just to esclude a possibile laptop failure.
Could you confirm whether you are currently using v4.10.0 beta or other?
Could you also let us know how the Flint 3 is connected to the Internet, such as Ethernet WAN or Repeater, and which Wi-Fi band the affected laptop is connected to: 2.4 GHz, 5 GHz, 6 GHz, or MLO?
If you are using 5 GHz, please try setting it to a fixed non-DFS channel, such as 36/40/44/48, with 80 MHz bandwidth, and check whether the issue still occurs.
Does the same issue occur on any other devices connected to the Flint 3 Wi-Fi, or only on this Windows 11 laptop?
When the issue occurs, could you please also try running the following two ping tests at the same time:
ping -t LAN IP(192.168.8.1)
ping -t 8.8.8.8
And check whether either ping shows increased latency or packet loss at the same time as the Teams call freezes.
If possible, please also export the system log after reproducing the issue, note the approximate time when the interruption occurred, and send the log to us via private message for further checking.
Hi Charles2 and thank you very much for your quick reply,
regarding your questions:
I’m using v.4.9, stable firmware release.
But it’s important to remark I had the same issue even on previous release (v.4.8.6 if I remember well).
The Flint 3 is directly connected to the internet by means of an ethernet WAN coming from my 2,5Gbps ONT. The main wifi streams over the three bands, 2,4,5 and 6 GHz.
I’m writing from the work laptop now, and looking at the properties of the connection I found that I’m currently connected to the 6GHz band, channel 5 (WPA3-Personal as security algorithm).
This specific issue occurs only on this laptop, even though seldom it happens that my mobile phone (Honor Magic Pro v7) reports a temporary absence of internet connection while I’m connected to the same wifi. It’s a matter of seconds, typically 2 or 3 secs, hence I’m quite confident the issue is about the connection and not the laptop (that does not lose any other wifi connection when I’m at office premises).
As per the PINGs, I’ll try my best but since this temporary “connection lag” only lasts few seconds, it’s difficult to catch the exact moment. I can surely note down a timestamp when a Ms Teams lag occurs, so that we can check the log.
I’ll keep you updated, thanks in the meantime for your kind support.
Thank you for providing the log and the timestamps.
We checked the log around the reported times and found that the affected client was repeatedly re-associating between wlan1 (5 GHz) and wlan2 (6 GHz).
For example, the following events were recorded around 17:48:
Tue Sep 1 17:47:57 hostapd: wlan1: STA d0:57:**:**:**:37 IEEE 802.11: associated
Tue Sep 1 17:48:27 hostapd: wlan2: STA d0:57:**:**:**:37 IEEE 802.11: deauthenticated due to inactivity
Tue Sep 1 17:48:32 hostapd: wlan2: STA d0:57:**:**:**:37 IEEE 802.11: associated
Tue Sep 1 17:48:50 hostapd: wlan1: STA d0:57:**:**:**:37 IEEE 802.11: disassociated
Tue Sep 1 17:48:50 hostapd: wlan1: STA d0:57:**:**:**:37 IEEE 802.11: associated
Similar re-association events also appear around 15:02, 17:45, 17:55, and 18:08.
This band change and re-authentication process may explain the brief interruption during the Teams call.
For comparison, please temporarily use different SSIDs for 5 GHz and 6 GHz, so that the laptop remains connected to only one band during each test. Under the same conditions, please test the laptop separately on the 6 GHz and 5 GHz Wi-Fi networks and check whether the issue still occurs on either band.
