Is ICS a good idea?

At my home I have an old P3 with XP PRO and all updates.  There are no other programs installed.
It is using a Cisco 350 Wireless Card to connect to the Antenna to obtain internet access from my local WISP.

This same computer has a cat 5 10/100 nic card that connects to my switch.  ALL IPS on my home system are statically assigned.

IS ICS reliable?  I seem to notices times when Windows XP on the ICS server says it has lost it's wireless connection, yet if I run the Cisco Aironet Utility, it shows I have signal just fine.  IF I reboot the ICS server, the connection seems to come back.

My isp in the past has had HUGE troubles maintaining a solid reliable connection so I also have doubts that is my system.

How reliable is ICS on a WISP?  Would I be better off using an Air Bridge direct to a ROUTER then to the SWITCH?

500pts as it is close to the end of the day and I want to know what to do before I go home from work.

ICS is software based and runs on top of the Windows operating system so by just that it is inherently less robust or reliable as a hardware based solution.  If you have the money, definitely go with the hardware router.  ICS also requires the host PC to be always on, something that may or may not be a problem.  A hardware router is built to run all the time.  Hands down, a hardware router is much more efficient and reliable than ICS.

definately choose something other than ICS... you can use a hardware router like suggested or try one of these links to other more robust software packages.. all you need a old clunker of a pc

http://m0n0.ch/wall/facts.php (or m0n0wall a CD-Rom based firewall/router)

there are lots of howto's out there on the net for each of these solutions.. just go with something that you feel comfortable with. m0n0wall is one of the easiest because there is a web interface iirc

All of a sudden my XP Pro SP2 ICS configuration is messing up things -i believe-  ! I  have a laptop (XP PRo SP2 also) and an xbox connected to the first machine (gateway), all of a sudden the gateway stopped giving out IPs properly, and won't accept connections from other nodes.

ICS is configured definitely, i can also FTP from the gateway PC to the xbox and transfer files (PUT), but xbox and laptop cannot talk back to gateway .

Problem is, all was working fine last night !!!

Any thoughts are appreciated.

Tks
