BrUcYNL,   Try this little tweak and see if it helps.     Go to device manager(right click my computer, left click properties, left click hardware, left click device manager). Click on Network and then right click on your wireless adapter, left click properties, power management. Uncheck the box, allow computer to turn off this device to save power.     Rick
Hello, Last week I bought a Dell Insirpon 1545. I have noticed when ever my laptop comes out of sleep I'm not able to connect to the internet. I get the message that my connection is limited. When start a command prompt and run ipconfig /release then do ipconfig /renew it is unable to renew the IP. If I disable the network connection and enable it I can then connect to my Wifi network and get an IP.  I have another laptop and I'm having no issues with it on my router. Also I have tried configuring the IP manually and once I come out of sleep it gives the same issue.   Any suggestions?
