I despise captive portal detection on devices. On our onboarding platform, I do everything possible to PREVENT the automatic popup of browsers due to problems like these (and many others). For you to really figure this out, you are likely going to need to do a packet capture of the session and see what that users phone is attempting to connect to. I would be doing a packet capture to poke some holes through so that the captive portal browser never opens in the first place.

Don Sullivan Network Administrator 205-726-2111 From: The EDUCAUSE Wireless Issues Constituent Group Listserv [mailto:[email protected]] On Behalf Of Thomas Carter Sent: Monday, October 10, 2016 2:40 PM To: [email protected]<mailto:[email protected]> Subject: [WIRELESS-LAN] Captive portal trouble with LG phones We use PacketFence as our NAC and have a captive portal to allow users to self-register their devices. In the past couple of weeks we've had problems with the latest LG phones (other Androids work fine) disconnecting in the middle of a captive portal session; it won't stay connected long enough to register the device. It seems similar to the old Apple "success.html" test for internet connectivity, but I haven't been able to determine if that is the case. Has anyone else seen this issue with new LG phones?
