Question Sony laptop WIFI drivers

[BigJohnx13]

Hi. I have a Sony Vaio Laptop VPCEH 16EG with Win 7 Home basic installed on it. I'm currently outside my country and only use laptop for emails and browsing.

A week ago I browsed and switch off my laptop. The next morning I could not log into any Wifi network. No Wifi connections is displayed in the local network display. When I connect a LAN cable it can still connect to the internet. In Device manager/other devices/HDB interface and network controller I get the yellow Exclamation mark. I tried upgrading the drivers which did not help. Then I uninstall the drivers and restart. Then I had no internet via Lan or Wifi. I download drivers from Sony and internet. This only restored the Lan port.

Another option was to disable the network in the Bios and in the Sony Vaio gateway with no prevail. Even the Wifi switch on the front show the display of Wifi but no Wifi connections itself. I do have the original disk at home which I can only access next moth.

How do I test if Wifi adapter is still working?
Any idea how to restore Wifi drivers?
Thx!

Try resetting your Network, open a command window (As Administrator)...
Type commands below, press "Enter" after each command......(no quotes on any typing)

"ipconfig /all" ( to see all connection /gateway info!
"ping 192.198.0.1" (or whatever your gateway address is....

also try to ping your ipv4 pc address in the list.
Then try....

(Press Enter for each command!)

"netsh winsock reset"
"netsh int ip reset"
"netsh advfirewall reset"
"ipconfig /flushdns"
"ipconfig /release"
"ipconfig /renew"

After this close cmd window and reboot to try network connection.

Check that the network adapter is showing in windows Device Manager and has no yellow exclamation marks next to it, and try updating the driver, by right-clicking on it to access the menu.

Depending on exactly what Wifi adapter it is, you could live-boot a linux distro from a USB stick or DVD to see if the hardware still works. That would be much safer for email and browsing online anyway. If wifi works then, the hardware is alive and you could reinstall the OS, or another OS.

If you find you want to install linux or Windows 10, I'd look at getting a small SSD to replace the 5400rpm 320GB hard drive. Otherwise i3-2310M and 4GB RAM is adequate for those tasks on either modern OS. You are using the IGP and the shipping configuration of that laptop is single-channel however, so it would be best to get another 4GB stick to upgrade to 8GB dual-channel if you haven't already done so.
