Network Card cannot receive packets but can send packets please help!

[Jason B.]

This is my last resort for help so I just want to say thanks for all
posts and help in advanced. Anyways here is whats going on.

Im running Windows 2000 Professional
1.7mhz celeron
Shuttle AV40S Board
256ddr ram
Geforce 4
and a Belkin network card, I have also tried Linksys

Now for some reason my internet just decided to stop working one day,
I assumed it was a virus and have reformated my hard drive numerous
times. I have even resorted to utilities such as BCWipe. My computer
is hooked up to a hub which runs to my cable modem but I have switched
ports on the hub and tried different cables and my good computer works
on port with any cable so I know all of that hardware is good. As far
as my computers board and the NIC I have tried using different network
cards that I know work and still nothing and yes I have tried using
different PCI slots with no luck. I have tried clearing my CMOS incase
something in the BIOS wasn't right and still nothing. What puzzles me
the most are these 2 things,

1. On thanksgiving day I reformated my drive and cleared the CMOS and
the internet worked for about an hour than it just stopped working. I
repeated the same process later that day with no luck. This was the
last time my internet worked.

2. My computer recognizes the hardware once its installed and acts
like its going to work but the connection just remains dead. The
activity light is constantly blinking too, all of the time in fact.
And what else is wierd about it is that although windows recognizes it
when I run the Setup off of the Belkin CD and same with the Linksys
card's software too both do not detect the network card.

I am completely stumped on this one and am about to throw my computer
out the window because its irritating me that it worked fine and now
it just doesn't wanna cooperate =P. Also I did test my PCI slots and
they all work fine somethings not right I'm just not sure with what.
Any Help is appreciated and if anyone who thinks they can help me
needs more information just tell me what you need I'll be happy to
post it a.s.a.p

Thanks
Jason B.

This looks like your problem. I infer from the use of a hub that there
is more than just your computer connected to the hub. Most ISPs will
only issue one IP address to a customer unless you pay extra for extra
IP addresses. A Hub is the wrong device to use here. You should be
using a DSL/cable router instead.

To test this out, power down your computer and modem. Be sure to power
down your modem by unplugging it from the wall. Connect your computer
directly to the modem. Now plug your modem back into the wall and wait
for it to register with the network. When it is stable, power up your
computer and see if it works. If it works OK, then there is nothing
wrong with your computer and you need to find a good router. If it
doesn't work, try leaving your modem unplugged overnight (to wait for
your ISP's IP lease to expire) and repeat the test.

HTH,

Have you ever compared the output of 'ipconfig /all' on both machines?

Just wanted to let ya know that it turns out my hub was the problem,
was kinda wierd that it just stopped working, anyways I had one last
question for ya, would a switch work instead of a DSL/cable router? or
should I not be cheap on this one and go for the router

Thanks again for the help

If you use a switch, then each device on your network will ask the
modem for an IP address. It is up to your ISP whether or not to allow
the modem to grant the request. If the modem allows multiple addresses
now and you aren't paying for them, then your ISP could at any time
limit you to one IP address at which time you will go through what you
have gone through now (only the first device to ask will get the IP
address) then you will have to replace the switch with a router anyway.
A router will also serve as a rudimentary firewall, isolating your
machines from unsolicited incoming internet packets designed to take
advantage of flaws in your OS to infect your machines. And at about
$50 for a router, it can't be that much more expensive than a hub.

Go with the router. IMHO, it's the best $50 I have ever spent.
Connect a hub to the router if you run out of LAN ports on the router.

HTH,
John
