Internet connection issue

OK, so I have a stable network connection through my modem at all times and of which is currently hard wired to my desk top. Every hour or so I seem to lose connection to the internet through my pc but the modem still shows a stable signal (online light stays on) I run the trouble shooter for internet and get nothing most times so I end up having to re-boot the pc to get connection back. I'm not the most tech savy so any suggestions on how to get this fixed step by step instructions would be VERY helpful !
 
First I would try replacing the Ethernet cable being used to connect the modem & PC. Next, if there are other "LAN" ports in the modem, plug into a different port. After that I would try pinging the default gateway (ip address of the modem) with an infinite ping and watch to see if there are dropped packets. if there are multiple dropped packets, then it could be a bad network card in the PC or a bad port in the modem.

to infinite ping, open the command prompt and type the following:

ping <ip address of modem> -t (c:\ping 192.168.1.1 -t)

to make the ping stop press: Control C look at the results and see if you have dropped packets. Here's a look at mine after 10 pings
