OS: Linux Mint 10 | Windows 7
Install Type: WUBI inside windows 7
Computer: HP Compaq Presario CQ56'
Network: Realtek PCIe FE Family controller w/ Realtek 8102E chipset
Problem in: Network Connection
Issue: After I woke up my computer from Sleep, I lost ethernet. No connection. It told me that I had lost my connection. Why? Now, after several restarts, nothing.

Hi boxmein, Welcome to LQ. Have you tried toggling the wifi switch? Could you post the results of the following please?

Code:

$ sudo ifconfig -a
$ sudo iwconfig

Good luck. ;-)

boxmein · 03-07-2011, 12:14 PM

Sure. I'll edit this as soon as I do.
ifconfig -a:
eth0 link encap:Ethernet HWAddr:xx:xx:xx:xx:xx:xx (I censored it for my privacy)
inet6 addr xxxx::xxxx::xxxx::xxxx::xxxx/xx scope:connection (Censored this too)
uP BROADCAST RUNNING MULTICAST MTU:1500 metrics:1
Rx packets:10 errors:0 deleted:0 overload:0 frame errors:0
Tx packets:21 errors:0 deleted:0 overload:0 frame errors:0
collisions:0 txqueuelen:1000
Rx bytes:1644 Tx bytes:4600
stopped:42 base address:0xE000
eo (Local address 127.0.0.1 and 255.255.255.255 nothing special)
iwconfig:
eo no wireless extensions
eth0 no wireless extensions

(I use cable internets)

Have you tried toggling the wifi switch?

Please post the output from the following:

Code:

# lspci -v | grep -i net
# lsmod

Good luck. ;-)

I don't use WiFi, but how do I toggle it?

This info will be useful for the ethernet as well. Please post it.

Also look at your dmesg output.

Code:

dmesg | grep eth
dmesg | grep rt

Check your physical ethernet connection as well, just to make sure everything is securely plugged in.

What happens if you try to connect as so

Code:

sudo ifconfig eth0 down
sudo ifconfig eth0 up
sudo dhclient eth0

My first log of lspci and lsmod: http://pastebin.com/K5treYQL
My second log of dmesg: http://pastebin.com/NcxRWBT6
I tried eth0 up, does it need a restart? It didn't work...

reed9 · 03-18-2011, 01:23 PM

Hrm. Everything looks ok from that. You're getting an ip address when you used dhclient. So you're connected to your router. I assume you're having trouble connecting to any websites?

Can you ping out?

Code:

ping -c5 www.google.com

If that fails, can you ping uses a google ip address instead of the name?

Code:

ping -c5 74.125.226.179

boxmein · 03-18-2011, 01:41 PM

Here:
~ $ ping -c5 www.google.com
ping: unknown host www.google.com
~ $ ping -c5 74.125.226.179
connect: Network is unreachable

PLUS Gnome's taskbar at the bottom shows a plug/socket sign. The plug and socket are separated ant there is a red X next to the sign.

BTW I am refreshing this every 15 minutes.

Peacedog · 03-18-2011, 07:46 PM

Can you ping anything on the local LAN?

Code:

$ ping -c4 192.168.1.1

How about issuing the following then trying to ping anything.

Code:

# iptables -F

then

Code:

$ ping -c4 www.google.com
$ ping -c5 74.125.226.179

Good luck. ;-)

I'll try tomorrow. Today I have a morning train ride in 5 hours and I want to get some sleep. Bai.

Peacedog · 03-19-2011, 12:45 PM

Let us know, at this point I'm thinking firewall maybe?

Good luck. ;-)

boxmein · 03-19-2011, 04:49 PM

It worked before...
