Hi everyone,
I´ve some strange situation with Android Smartphones in our Aerohive/Extreme Network (Mix of AP250 and 305C) environment.
The Android devices itself get´s an valid IP and authenticated to the Wifi but shows the information “maybe don´t have internet connection”.
Actual Workaround: Ping the device. The first 2 packages are lost, but than the device replies and shows connected.
I´ve started this discussion last year, but with Covid-19 the situation stuck.
I´ve also found that we are not the only one with this situation.
I can confirm that DNS port 53 and 853 is open for this dedicated Wifi VLAN on our firewall.
I´ve added the DNS ports for the native VLAN of the APs to this internal DNS server, now.
Does anyone has an idea, if this won´t help, how we could troubleshoot this?
Thankful for every idea!
Solved! Go to Solution.

Hi,
I want to send an update about this topic.
We found the root cause for our problem, but I´m unsure how to solve it.
The ARP-cache on our firewall which is also the Gateway for our Guest Network seems to get some wrong information from the Aerohive environment.
The Guest Wifi has a short Lease time on DHCP side (5min, increased to 15min now).
The client itself gets the correct IP from DHCP Server (same VLAN/subnet, Windows Server), but the Firewall still get´s the wrong information after a arp-cache clear.
We deleted the "wrong" client in the IQ Management and cleared the ARP-cache once again and the problem was solved for this device.
We found an option in the "Management Options" called "disable Proxy-ARP":
Would it make sense to activate this option in a Wifi environment?
Arp-Caches are written on the Gateway and Switch devices.

Hi everyone,
I’ve recently been testing a few Android devices on our Wi-Fi network, and I’ve noticed a strange pattern that might be related to what others mentioned here — devices connect successfully, but during gameplay, the internet connection drops for a few seconds and then reconnects automatically.
It’s especially noticeable while testing lightweight games like Null’s Brawl, which depend heavily on consistent ping. I tested the latest Android build from here → https://nullsbrawl-apk-indir.com.tr/ and the issue only appears when switching between 2.4GHz and 5GHz bands or when roaming between APs.
It doesn’t seem DNS-related (ports 53/853 are already open). Could it be something with DHCP lease timing or network authentication delay?
Would appreciate any insight from others who’ve dealt with this — maybe a client-side setting or AP adjustment could fix the instability.
Thanks in advance for your suggestions!

YEARS later and I still get the same error from time to time on some random students Android based devices (never with iOS devices)
Completely insane
