I wonder if "Interrupt" affects internet connection.

eth0      Link encap:Ethernet  HWaddr 60:eb:69:6c:55:83  
          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)

eth1      Link encap:Ethernet  HWaddr 4c:0f:6e:6c:d2:9f  
          inet addr:  Bcast:  Mask:
          inet6 addr: fe80::4e0f:6eff:fe6c:d29f/64 Scope:Link
          RX packets:159717 errors:0 dropped:0 overruns:0 frame:24945
          TX packets:155355 errors:40 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:1000 
          RX bytes:224953980 (224.9 MB)  TX bytes:13688161 (13.6 MB)

In this case its most likely a dropped packet. Interrupts are how computers call fucntions at the CPU level. You load the registers and the stack and then generate an interrupt.
But if you really want to understand about interrupts, check out Wikipedia.

This is incorrect. It's simply the IRQ number as stated by @Mowgli – xofer Mar 11 '15 at 14:06

The interrupt refers to the interrupt number used by the network adapter. See the breakdown of ifconfig for more details.

Interrupt numbers are assigned to hardware devices by the kernel. They are used to multiplex the few interrupt channels that the CPU has between many hardware devices. You can see all interrupt numbers being used by executing cat /proc/interrupts/
