Routers use DHCP in two ways:
1 - For the Internet connection to get a public IP address from your modem (a DHCP client)
2 - For the internal network to give computers connected to your router or wireless a private IP address (a DHCP server)
It sounds like you've disabled the DHCP Server in the
LAN Setup > Lan Settings panel of your router admin page. This means that your router will no longer provide you with an internal IP automatically. If your laptop (or another computer in the house) has an ethernet port I would recommend using that instead of messing with your wireless settings. Here's the steps that should fix the problem of the disabled DHCP server:
- Goto Control Panel > Network Connections
- Right-click on your Local Area Connection adapter and select Properties
- Double-click Internet Protocol (TCP/IP) from the list to bring up its properties
- Change the selection from
Obtain an IP address automatically to
Use the following IP address: - Fill in the fields as:
IP address:
192.168.1.23 Subnet mask:
255.255.255.0 Default gateway:
192.168.1.1- Click OK, OK on both screens to save the settings
- Connect a network cable between your computer and router
- Open your browser and see if you can connect to
http://192.168.1.1 (if not, reconnect your router's power and restart the computer)
- On the router's admin page, goto the
LAN Setup > Lan Settings screen, change the DHCP Server setting from Off to
On and click Apply changes
That should fix it, disconnect the network cable and try your wireless connection again. If all's good, you can go back to the Local Area Connection in your control panel and change the TCP/IP settings back to
Obtain an IP address automatically.
Good luck
