Wifi & LAN connected by no internet (after cleaning fan). Bios clock related?

(1/1)

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 :D)

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
--- End code ---

--- Code: ---ifconfig -a
--- End code ---

--- Code: ---ip r
--- End code ---

--- Code: ---route
--- End code ---

--- Code: ---ip n
--- End code ---

--- Code: ---arp -a
--- End code ---

--- Code: ---ping _gateway
--- End code ---
terminate command with 'ctrl c'

--- Code: ---ping 8.8.8.8
--- End code ---
terminate command with 'ctrl c'

--- Code: ---ping google.com
--- End code ---
terminate command with 'ctrl c'
