The network adapter and the other device both try to get the attention or "interrupt" the processor (CPU) at the same time. This "confuses" the processor, and may cause it to lock up (freeze) or keep the computer from booting all the way up.

The simplest way to try to fix this problem is to shut down your computer, unplug the power cord and move the network adapter to a different, available slot inside your computer.

Reconnect the power cable to your computer and restart.

The reason of not able to surf online might be due to your computer is not able to obtain a full packet from the wireless router for the first time. Please first check the distance between your computers to the wireless router. By moving your computer close to the wireless router at this stage, your computer can easily obtain IP and solve this issue. If moving closer to the wireless router still didn’t solve the issue, please follow below steps. 
Step 1 Click Start > Control Panel > Network and Internet Connections > Network connections.

Step 2 Right-click on the Local Area Connection which represents your network card and select Properties.

Highlight Internet Protocol (TCP/IP) and click Properties.

Step 3 Click Select Obtain an IP address automatically. Select Obtain DNS server address automatically. Click OK

The above step should help the computer automatically obtain an IP address. However, if you still can’t get online, please follow the rest steps which you will need to assign IP address manually.

Step 4 Click Start > Control Panel > Network and Internet Connections > Network connections.

Step 5 Right-click on the Local Area Connection which represents your network card and select Properties.

Highlight Internet Protocol (TCP/IP) and click Properties.

Step 6 Set Subnet Mask 255.255.255.0

Step 7 Set Default Gateway the same as the LAN IP address of your router (192.168.0.1).

Step 8 Set Primary DNS the same as the LAN IP address of your router (192.168.0.1).

Step 9 Secondary DNS is not needed or enter a DNS server from your ISP.  Click OK twice. You may be asked if you want to reboot your computer. Click Yes.

After you reboot, the computer will now have a static, private IP address.

These steps should provide your computer with a set of fix IP address which should solve this unable to receive IP issue.

Step 10 Some newer ADSL/Cable modems are now equipped with a battery for when power is lost, i.e. Time Warner Cable Modems, will keep the modem on and connected. Due to the ADSL/Cable modem not assigning the correct DHCP information, the Rosewill Routers can not work correctly and assign a DHCP to the client computers. Please try the following steps below:

1. Configure your settings correctly i.e. DHCP, SSID, Password.

2. Save your settings.

3. Reboot your Rosewill Router and your ADSL/Cable modem.

4. If rebooting your ADSL/Cable modem doesn’t work, please call your ADSL/Cable provider and ask them to reset and restart your ADSL/Cable Modem.

If all of the above do not work, please give us a call at 800-575-9885 so we may further assist you.
