Internet not working
I am in a big trouble. I am working in an organization as Network Administrator. My complete network working very well. In my whole network all PCs are connected with router which have Internet access IP and Router is connected with a switch which connected with server and Internet connection. So all PCs using Internet and Network at a time. But in my General manager PC Network is working well but Internet is not working, yellow sign show on WI-FI icon. So I use commands "ipconfig /flushdns , ipconifg /release , ipconfig /renew" then internet start working. But the problem is this I use these commands daily. When he come to office then he open his Laptop using network and when he want to use Internet then he call me and I do these commands. This problem is occurring from few weeks. So please help me urgent. Thanks

Hello, What type of laptop and what OS? Does this problem occur intermittently during the day or is the problem present only when he comes in each morning? If he restarts the computer, does it begin to work OK? Does it occur after the laptop goes into sleep or hybernation? Are you using Windows wireless client or a 3rd party software for the wieless connection? If you disable wireless and plug the laptop via ethernet cable, does teh problem still occur? I would begin by disabling hybernation, screensaver, etc. putting on an 'always on' power mode just to eliminate whether or not the problem is being cause by sleep/hybernation.Miguel Fra | Falcon IT Services, Miami, FL | | Blog

p.s. in the BIOS look under the processor for C3, C4 sleep states and disable them. There are known bugs with c states not waking back up properly. Miguel Fra | Falcon IT Services, Miami, FL | | Blog
