Auto IP Detect Not Working

[Guest]

Help would be fantastic. My PC had loads of problems, so i did a total format and reinstall of XP Pro. PC started up, and I downloaded all the patches (internet ok at this point). Next day, I start up and my internet is gone. everything else is ok, just the internet is shot for some reason.

I am using a cable modem, adn we have 2 pcs on the hub and we have had no issues before. I boot up and the settings are on autodetect for IP and for DNS, so I should not have to enter anything. LAN properties has 'Invalid IP Address' and zeros for the rest of the options.

I click on 'Repair the Connection' and I get an IP in the 169....range which is invalid for Internet access and a subnet mask of 255.255.255.0.

The Nic fires up and works ok. i've tried 3 different cards, one of which is brand new.
Cannot ping anything (http's or IP's)
Cannot access webpages through IE

Any help would be pretty sweet...thanks

This means that the PC is not seeing the router for some reason or another.
It may be a faulty network card, faulty cabling, or a bad router/hub port.

Do you have a router? Try adding a network address manually and see if you
can see the router (usually 192.168.1.xxx or 192.168.0.xxx). Make sure you
have DHCP enabled so you will get an assigned address in the network. If
you change the router setup, you can go back to your computer, remove the
manual network settings, reboot and you should have the correct addressing
scheme.

If you don't have a router (which you should if you have a DSL/cable
connection), you will have to keep a manual addressing scheme for both
computers for them to see each other.

If you don't have a router and changed your NIC, you may have to call the
cable company so they can reset your connection. They are very good about
trying to stop shared connections by using your NIC's MAC address to
identify your computer on their network. Changing NIC's will stop your
connection. You can get a router and it will clone your MAC address in the
router to show your NIC's MAC to the cable company.

Do you know your router's IP address (usually something like 192.168.0.1)?
Try pinging that. If you can't, then Richard G. Harper is probably right.

Can the other PC access the Web OK?

The one other PC sharing the hub works OK. as I said I have an on-board NIC setup that I was using before, and i've tried 2 other NICs that have not had any luck either. I've tried just having my PC on the hub alone to see if there was a conflict in that arena.

Try 1 : I tried a few cables, including this one that i'm connected to now and all the cables worked on PC1, but not on mine.

Try 2: I'm going to try to find the router IP since I'm not sure where it is right now, or how to find it

The computer that is connecting is connecting directly to the cable
connection and is assigned the IP address by your ISP. There appears to be
no router setup in your configuration. Your other computer will not be able
to connect in this configuration since you can only have one address at a
time by your ISP. Is the computer getting an address plugged directly into
the cable modem?

No dice on the direct connect from the cable modem to the NIC. I'm on the working PC now, which works ok from the hub and direct, so i have no clue what settings may be off.

i've tried an xp reinstall and no luck either. i'mjust out of ideas

 

[Guest]

i'm grasping at straws...last shot...are there any viruses going around that may be doing this sort of thing? since a did a fresh reinstall without an AV until I downloaded the patches and updates online, that did leave my PC open for a bit...just a last gasp of an effort to try to figure this thing out.

thanks everyone for helping

 

[Karl Burrows]

It's going to be first come first serve if you plug them both into a hub.
Since it does nothing but forward the network request and nothing else. You
can get the Linksys of Netgear routers cheap and they give you a firewall
for your always on connection.

The router acts a gateway so that the ISP only sees one connection so
regardless of how many computers you have connected behind the router, all
can connect through the router.

I'll give it a shot tonight after work. It just boggles the mind that the

one PC works with the hub when it or multiple PCs are connected, but the
other one will not work alone on the hub.

If the non working PC works alone with a direct feed from the cable modem,

what is the solution? shell out $50 for a router to make sure I can get my
own IP all of the time?

 

[Karl Burrows]

Tell me if you are actually using a hub or router to connect both computers?
A hub will not let you connect more than one computer and since the other
connected first, it is going to get the connection no matter how many times
you reinstall XP without removing the other computer from the configuration
(and even then, cable modems are notorious for keeping up with MAC addresses
so it blocks other computers from connecting).

You can buy the router or use ICS (Internet Connection Sharing). I would
highly recommend purchasing a router for firewall protection with your cable
modem.

Using a Hub (Hawking PN500TB MiniHub) to connect both PCs to one cable modem connection. i agree that a router is more effective; we've just been using this hub for a while now.

 

[Karl Burrows]

The only way you will be able to connect multiple computers is using the
router. That will fix all your problems. Let me know how it works.

It may be that your IP recently changed to allow only one P/C to connect
without an extra fee. This might explain your problem. A typical router can
emulate a MAC address of a P/C such that all P/Cs connected appear to be the
same MAC address as set in the router. As to a router based firewall-- Most
home or small business routers provide a "NAT" firewall. This is basic
protection only. With such a router, you will also usually need to run
something like Add Aware, an antivirus program, and some sort of antispy
software.

He doesn't have a router, so this doesn't apply.
