Hi,
We have 3 Sophos Wi-Fi networks, one hotspot for guest, one for employee and one for company devices.
When we connect with a device that never connected before to the wireless networks we have no internet but only network connection.
With the hotspot we don’t see de portal but about 30sec later we can access the portal.
We can immediately ping the gateway but no external ip address.
After about 30 seconds later we have internet and can ping any external ip addresses. The strange thing is when we connect a 2nd time there is no problem at all.
Even after some weeks we can still connect immediately to the wifi networks without any problem.
The problem accurses with the Hotspot, WPA2 and (Bridge to Lan networks).
When we connect to the Wi-Fi networks we receive the correct network configuration from the DHCP Sophos or the internal windows DHCP service.
At the first sight the gateway of the SF does not immediately works after connecting to the Wi-fi network for devices that has never connected before.
When the connection works after about 30 seconds and we connect a 2nd time the gateway is working immediately even after removing the network settings from the computer. The CPU load is always below 10%.
I am not sure when the problem showed up but we have it on multiple Sophos devices with the same firmware (SFOS 15.01.0 MR-3) .
What can be the cause of this problem?
Does any one else has a similar problem?
