Wireless network will not allow re-connects after a day or so.

Holli Davidson

Initially the WiFi network works properly in all ways. My problem is this: wireless devices are not able to connect after about a 24 hour period. I have setup multiple Sophos XG routers with WAPs and built-in WiFi but this one is giving me grief.

I have an XG125W. I have deleted and rebuilt the wifi network, zone, dhcp, and policies multiple times.

If devices never leave the wifi they stay connected and pass traffic and the SSID is still being broadcast after 24 hours. It just won't allow new connections.

Turning the Wireles Network off and back on fixes the issue for the day but it just resets the situation. DHCP isn't running out of addresses and increasing the lease time doesn't have any effect.

I have 2 wireless networks (a private and guest) and this happens with both of them.

 

What am I missing? Does anyone have any ideas or suggestions?

 

Thank you for your time and help.

    Mark,

    I do not have this problem on my XG.

    Can you give us more information about your configuration? I mean:

    Wireless Network type (bridged, zone)

    Encryption used

    Are you using clientless users?

    Thanks

    WPA2 Personal

    Separate Zone

    TKIP (only abg)

    2.4 and 5 Ghz

    Clientless users

     

    Does that help? I have tried bridging the private wifi to the internal network but couldn't get the DHCP to work from the internal network properly. Zones seem like a better way to do things and that is how I have been doing them so I didn't put too much effort into that route.

    Holli,

    by default if a device receives an IP address from the DHCP server (where the lease is for example 8 hours) and you move the same device (so same mac-address) to another wireless network belonging to another zone (different ip) you will not receive the correct IP address (because it is already registered from the first DHCP server).

    Make sure to enable dhcp global option from commad line. Use ssh or cli to connect to XG, option 4 and type: "system dhcp static-entry-scope global" without quota.

    Hope this helps!

    Thanks
