Lost some internet connectivity


Hi guys,

I am running LM 17.3 on my laptop. Yesterday I tripped over the power cable and then when I started the computer again, I couldn,t browse anymore. I thought it was weird because it was showing that the wifi is connected as normal. I have another computer (desktop) also running LM 17.3 and everything is fine with that one. I use the same wifi dongle for both computers. So the problem is not with the dongle either.
Then I was very surprised that skype is still working just fine! Very very weird.

So I went to try to ping -c 5 google.com to no avail. it says: ping: unknown host google.com
pinging -c 5 8.8.8.8 the average ping is 2 s with 20% lost packets.

It's weird that some services like skype are still working but not browsing, email, or other.

When I connect to my root user, it boots up and says: Cinnamon just crashed. You are currently running in Fallback Mode. I'm pretty sure this is related problem because it never said that before.

I can't see anything else that maybe since the hard drive was not umounted properly, maybe there was some corruption that occurred during the power outage? I'm surprised because ext4 has journaling capability.

Any suggestions guys to find the source of my problem, repair the files in question? Or will I have to reinstall linux mint from scratch again?

Thanks in advance guys.

If you can ping an ip address, but not a domain name, that indicates that the issue is likely related to DNS.

Is this machine DHCP or does it have a static ip?

Here's a general article that might help: http://www.tecmint.com/linux-network...ting-commands/

Is the DNS configured properly?

Type:
Quote:
cat /etc/resolv.conf
and check the output or post it back.

Thanks frankbell and JJJCR for your help guys...
Frankbell ifconfig -a is normal wlan0 is up and I see traffic
/etc/network/interfaces
# interfaces(5) file used by ifup(8) and ifdown(8)
auto lo
iface lo inet loopback

Shows the same on my both computers. The one that works and the one that doesn't so that's good.

However /etc/resolv.conf shows:

# Dynamic resolv.conf(5) file for glibc resolver(3) generated by resolvconf(8)
# DO NOT EDIT THIS FILE BY HAND -- YOUR CHANGES WILL BE OVERWRITTEN
nameserver 1.2.3.4

... on the computer that's not working, while showing : 127.0.1.1 on my desktop that works.. I guess we are on a lead there..

Did the laptop take a fall? If so, what is the SMART data of the drive?
