Some devices not connecting to internet

yuksun

Hi there,

Apologies in advance as I am a complete beginner. Just back into work in a month and we have a XG firewall installed. but something isnt quite right.

We have created a rule to allow connection for our wireless devices to connect to the internet. But none of our wireless workstations are connecting to the internet, but the strange thing is the majority of mobile phones (not all, just some) are working on the same SSID were connecting to!?

I cant ping any external OR internal ip addresses but I am connected to the wifi.

I look on the logs in XG but i dont see the IP address of the workstation im testing with.

Can anyone give me any advice on how to troubleshoot this as i dont know where to start... knowing that it doesnt work on any wireless workstation ive tried (around 10) but many mobile phones work completely fine?......... 

Sorry I hope i make sense...if you need anything further please let me know!

Thanks!!!

    Hi ,

    Thank you for reaching out to the Community! 

    Do you have Sophos Access Point? If yes, did you configure the bridge to the AP LAN wireless network? 

    Please provide screenshots of the wireless network and DHCP server configuration. 

    Thanks,

    Hi Harash,

    Thanks for getting back to me. No we use the Sophos Access points.

    Not sure if this is what you needed to see, we have a separate port used for the wireless going into the XG firewall.

    Our DHCP is an internal win 2016 server on the PortA1 side of things.

    Baffles me why mobilephones work but our Win 10 wireless workstations dont?!

    Hi ,

    Thank you for the update! 

    Could you please provide the screenshots of the wireless network configuration from the Wireless > Wireless network > Open the configured network and take a screenshot of the general settings? 

    The Windows DHCP server configured for PortA on the firewall is overlapping with the PortA2. I would suggest you ensure there is no network overlapping between different interfaces. 

    Thanks,

    Hi Harsh

    Thanks for getting back to me. Ah ok, ill check the addresses, just coming from a Sophos UTM we are just trying to copy over like for like.

    We dont have anything in the wireless network bit, i take it I need to create my SSID there too?

    Thanks again!

    Hello Yuksun,

    Thank you for the screenshot!

    If you are using Sophos Access Points, yes you would need to configure them under Wireless Networks.
