Dear Sir, I am Zahid Bhatti from an IT department, I have 2 DSL modem 1st is connected in wired network switch through my computer(Server)enable simple network card sharing,so they can use internet and printer devices over the network every thing was working fine,after I decided to connect a wireless router with wired network because my C-E-O has a laptop WiFi enabled . I plugged 2nd DSL modem cable into the wireless WAN port (Never change any settings) in Laptop internet browsing is fine but not see any shared local folder as well as printing devices. Then I joined both (Wireless router & Network wired switch) with LAN cable, and after that DHCP conflict issue occur in my network every wired network client pc receive only wireless network instead of wired settings. Please tell me how can I manage same network on both devices. This case DHCP should be enabled on wireless routers because I want keep dynamic settings on C-E-O laptop. Thanks & Regards, Zahid Bhatti Creative Apparels (Pvt) Ltd.

    What you need to do is set up the Wireless Router to use a seperate IP subnet for the Wireless devices. This can then be used for DHCP and not effect you other DHCP server.Then what you would want to do is set up the SSID security so that you are authenticating onto your corporate network so that they will be able to route to internal servers. This authentication should be done by machines in your AD domain and aswell as your users username and password. This way people would not be able to just get a username and password and gain access to company data.

    What you need to do is set up the Wireless Router to use a seperate IP subnet for the Wireless devices.   That might not be possible. We need to know more about the equipment, which might be fairly old. Note that the term used was "DSL modem" and that might indicate some restrictions. I have a DSL modem in use here, and I cannot access its connection to DHCP which is provided by the ISP. I don't know what IP subnet might be used, nor do I care.   Inside of that, I have two of my own routers. Both are wireless and provide their own DHCP services in separate ranges to connecting devices. (Connections between the two sets of devices is strictly controlled. One set is much more 'public' than the other.) Both also NAT to the outside and that helps me not care about the range provided by the ISP.   We need some specifics about the actual equipment.   Tom
