Wifi Seperate Zone Performance

Andreas Leopold

Hello!

I have a strange Problem.

My XG Firewall has connected a RED 15 with 2 AP15.

The AP15 are used for 2 Wifi Networks:

Internal Wifi (Bridged to AP LAN)

Guest Wifi (Seperate Zone)

 

The Internet Connection is 20/5MBit. In the Internal Wifi i can Use the full 20/5 Mbit - the Speed Tests are Okay.

In the Guest Wifi i have only 0,5MBit Download, the Upload is OK.

The Problem exists since i installed the RED and 2 AP's. Before the 20/5 Connection the RED was behind a 8/0,768 Connection and i thought the Problem is because the slow Upload. But with the new Internet Connection the Problem still exists.

I tried several Things from here:

  • I created a new Seperate Zone Interface
  • I set offload tso off
  • I made a IPS Exception and tried to stop the IPS Service

The Problem still exists. Can anyone help me?

    Thank you, i haven't seen this Thread yet.

     

    Now i deleted the AP's, the AP Group and the Seperate Zone.

    The New Wifi is created with MTU 1500 - when i Accept the AP's and Assign the Wifi, the MTU gets 1450.

    Offloading is disabled on the new Wifi, but the Performance is again only 0,5MBit Download. Upload is fine.

    I changed the MTU manually to 1500, but the problem still exists.

    Now i can note the Speedtest starting with about 5-6MBit dfor about a Second, then it gets down to 0,5 MBit.

    DDOS Counters are all at 0. :(
