I am on a cable modem shared with 2 others through a linksys hub. Using any computer other than my own to ping my computer results in full packet loss. My computer is up and running.

My i.p. address is: 24.116.179.123

can they ping eachother? yes
 can they ping a machine on the internet? yes
can you ping a machine on the internet? yes
can you ping yourself? yes

But no other computer can ping my computer, wether they are on my network or not.

My computer connects to the internet fine and can ping itself and other sites perfectly, but no other site can ping(connect) to mine.

Do you have personal firewall installed on your PC?  Such as ZoneAlarm.  If so, try disable it and then ping again.

can you give the other IP addresses
My i.p. address is: 24.116.179.123
#2 = 24.116.49.53
#3 = 24.116.54.253

 and all 3 subnet masks(yours and the other 2)?
How do I look them up on WinXP?

also the default gateway IP addresses?
24.116.48.1

I do not know if the firewall on XP is enabled by default. I will ask if you can connect to a TCP/IP service on any of the other 2 pcs. If so, then there is no problem with the IP addresses and the subnet masks. And then we can conclude that your machine do not reply to ICMP echo requests. By the way, I can ping the other 2 machines from my PC but I cannot ping yours, either. So there should be a program on your PC that discards ICMP echo requests which may be the firewall on XP that 'stevenlewis' stated.

The program is Internet connection firewall
you should check the settings of it and maybe look at the manuals about it. I cannot give any further help as i do not have an XP machine.:(
