sir,my question is having firewall (SOPHOS XG 135) , i am using wifi accesspoint, and laptops connected to my wifi  i cant access from wired connected systems or laptops within the same network.occasionally i can access, but there is no permanent solution for this.

Please help me out.

Are you using XG firewall or UTM? You are posting in the UTM forums...

Also, please describe in more detail what you have done, are you using VLAN's or not, how is everything connected. We don't really know anything about your configuration hence it's very hard to give you any help.
