Hi, This seems to be a question many people are asking, but as I didn't find a definite reply to it, I thought to ask it again with my exact system info and keep my finger crossed for a solution. Problem Description: Windows 7 cannot connect to my wireless router everytime the system is restarted/hibernated. Interestingly, not only it easily connects to the internet once I use the ethernet cable to connect to the same router, but I also it recognizes the wireless connection and soon after I can remove the cable and continue on the wireless. Of course, the same story repeats once the system is restarted/hibernated. I have had Vista before, and never had this problem, the only change in my software/hardware that seems to lead to problem is the installation of 7. I have tried updating all the drivers from Dell, and to my knowledge, they are all properly installed.

Hi, This issue can occur by incompatible driver or incorrect network settings. To troubleshoot the issue, please perform the following steps. 1. Temporarily turn off firewall on the machine and upgrade the Wireless adapter driver to the latest one. 2. Perform a Clean Boot to check the result. 3. Assure the WLAN AutoConfig service is started. 4. Upgrade the router’s firmware. 5. Assign a static IP address and DNS address on the machine. a. Click "Start", input "NCPA.CPL" (without quotation marks) and press Enter. b. Right click on the connection that you use for the local connection, and then click "Properties". c. Click “Continue” to verify the administrator permission. d. Click to select "Internet Protocol Version 4 (TCP/IPv4)", and then click "Properties". e. Select “use the following IP address”. Manually set “IP address” (For example, if your router IP address is 192.168.1.1, we can type the IP address as 192.168.1.22. If the router IP address is 192.168.0.1, we should type in 192.168.0.22.) Manually set “Subnet mask” as 255.255.255.0 (Note: We can use this address as the default subnet mask.) Manually set “Default gateway” (Note: Default gateway is the IP address of the router.) Manually set “preferred DNS server” (Note: Preferred DNS server is also the address of the router.) f. Click “OK”. If the issue persists, please restart the machine and run IPCONFIG in Command Console, and then post the result here.
