I'm visiting my dad. He said that suddenly he has no internet on his laptop (Vaio VPCF11C4E / PCG-81112M). I myself have looked again if I find something. About Wi-Fi you will garkein network displayed (the on / off switch on the housing of the laptop is on (for the wireless)). You do not get anything via LAN. OS is Windows 7. Maybe someone of you has an idea how it might work.
Has the wireless router a DSL signal. The laptop does not seem to be the cause.
Me and my dad are in the wlan, with our cell phones… So it should be ok. Somehow lie on the laptop
Have you ever checked in device manager if everything is OK with the network adapters.
Made about 2min ago. Everything's o.k.
Make Bluetooth on the laptop.
Or follow this wizard at Microsoft:
Also check if the laptop gets an IP address from the router.
Enter CMD console ipconfig / all.
Using the Windows Control Panel, examine where the connection to the Internet is interrupted. Only when you know that, you can search for a solution and find. There are many places. I would definitely first PC and router stop, wait and then reconnect and watch the screen at startup. Ricardo
