I am using Linux mint. And this is my kernel.
uname -a Linux nithesh-desktop 3.8.0-19-generic #29-Ubuntu SMP Wed Apr 17 18:16:28 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux
I was having a networking problem, when I had used Lubuntu. So, I installed Linux Mint, thinking that it was a software issue. But even when I had linux mint, the internet didn't work.
Critical info: During a lightning strike, my modem's motherboard fried, along with the ethernet port attached in the computer. I bought a new modem, and a new External Ethernet Port [RTL-8139/8139C/8139C+]. It had worked for a few days, before the internet crashed again. I was downloading a torrent (for about 26 hours), when it abruptly stopped working.
I was wondering whether this was due to 'collision'. EDIT: Through BIOS settings, I have disabled the inbuilt ethernet card.Even after that, the network isn't working.
ifconfig gives me this result.
eth0 Link encap:Ethernet HWaddr 00:e0:5c:00:42:aa UP BROADCAST MULTICAST MTU:1500 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:0 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:0 (0.0 B) TX bytes:0 (0.0 B) lo Link encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 inet6 addr: ::1/128 Scope:Host UP LOOPBACK RUNNING MTU:65536 Metric:1 RX packets:190 errors:0 dropped:0 overruns:0 frame:0 TX packets:190 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:27879 (27.8 KB) TX bytes:27879 (27.8 KB)
I later found out that eth0 is my new ethernet card, and eth1 is the old, fried, non-working one.

cat /etc/network/interfaces gives me the following output:
# interfaces(5) file used by ifup(8) and ifdown(8) auto lo iface lo inet loopback
sudo iptables -L -nv gives me the following output:
Chain INPUT (policy ACCEPT 0 packets, 0 bytes) pkts bytes target prot opt in out source destination Chain FORWARD (policy ACCEPT 0 packets, 0 bytes) pkts bytes target prot opt in out source destination Chain OUTPUT (policy ACCEPT 0 packets, 0 bytes) pkts bytes target prot opt in out source destination

ip link gives the following output:
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN mode DEFAULT link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00 2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP mode DEFAULT qlen 1000 link/ether 00:e0:5c:00:42:aa brd ff:ff:ff:ff:ff:ff
I have a question though. Is this a software problem or a hardware problem?
Please help! I've been suffering without internet for a month!
