Wifi & LAN connected by no internet (after cleaning fan). Bios clock related? - jam_27 - 02-19-2022

Hi,
I have got Linux 3.8 32 bit on my Vaio VGN UX1XN.
I decided to open the unit and clean the fan.
I put the machine back together after a week and fired up the OS at which point I noticed that I there was no internet connection even though the wifi is showing connected.
Upon checking the bios and the time was off so I corrected the time and restarted the machine still with with no internet (wifi still showing connected).
I then checked with a live distro and wifi and internet worked.
I have also checked with direct LAN connection. LAN gets connected but I cannot connect to internet.

So something appears to has gone wrong in the installed OS (perhaps related to the bios clock) and I would appreciate some diagnostic guidelines to fix the issue.

Thanks,
(I am not an experienced Linus user so please be gentle on me Big Grin

Can't help with version 3.8 - it is no longer supported and it is not advisable to expose to the internet.

For network trouble shooting on a simple home network you can do a bit of investigating into a connection that says connected but doesn't work.
Open a terminal window on the machine that isn't working (by pressing 'ctrl+alt+t') and provide the output of the following commands

Code:
ip a

Code:
ifconfig -a

Code:
ip r

Code:
route

Code:
ip n

Code:
arp -a

Code:
ping _gateway

terminate command with 'ctrl c'

Code:
ping 8.8.8.8

terminate command with 'ctrl c'

Code:
ping google.com

terminate command with 'ctrl c'

When it says connected

Go to terminal and do the following 2 commands

ping bbc.com

ping 8.8.8.8
