Swapped motherboards: No Internet Now

[Killrose]

Ok, swapped out my KT266a based motherboard for another one with-out re-formatting. Everything works fine except I cannot access the internet. I'm using Linksys 10/100 fast ethernet cards thru a router. I know my cable service provider and my Router works ok because i'm using my second comp right now.

I show no conflics as far as IRQ's go, and I am only showing one adaptor in safe mode so I know i'm not trying to use several at once. However, I'm thinking I need to get into the registry to edit out old profiles or redirects, as when I try to use IE, I instantly get an error report pop-up screen.

I'm using Win98se. And I have tried to set-up and use the comp directly thru my cable modem and that was also a no-go.

Try getting the latest drivers on a 3.5" disk from your other machine, removing the adapter, re-detecting the device and installing from the newest drivers off the floppy, see if that fixes the problem. Windows is such a POS

 

[Killrose]

I do have the proper drivers for the adaptor, and I have removed and installed it several times in different PCI slots. I also tried a different NIC (an SMC) with the same result.

Funny thing is, this particular computer though it won't access the net, will see my other computer on the network.

I had this same problem. The only way I could get it to work right was to reset the router. You might try that next.

If you have LAN connectivity but not WAN browser connectivity (internet) it's usually DNS. You might try manually assigning DNS numbers and see what happens.

The other computer using the router has no problem. But I guess I can try it. I beleive I did early on, but I may try it again.

Start through the different levels:

Can you ping 127.0.0.1: Tells you whether your IP stack is up and running
do a winipcfg or ipconfig or ifconfig (winME/9x or Win2K/XP or linux/unix). Can you ping your given IP address: Tells you whether your Card is functioning correctly
Can you ping your router and/or DNS server: Tells you whether your cable is connected correctly and whether the link is fully functional.

This is usually a good way to start troubleshooting network problems.

 

[Killrose]

when I run winipcfg, I get the numbers and not blank boxes. I can't ping the router to set it up. I have'nt tried to ping the IP stack, but functionality seems to end with trying to use the browser for anything.

When I boot into safe mode, I see only the one NIC I have, and checking my IRQ's, I show no conflics.
The IRQ of my NIC is 3, and I have tried removing it and re-installing it in a different IRQ, and it still won't work.

I have done a full set-up/reset of the Router. My other PC can access and set up the router normally, but the problem PC is a no go.

 

[ktwebb]

You said your problem PC can see the other PC's. I assume you mean Network Places/Neighborhood which is a terrible connectivity tool however if you can verify that you have PC to PC connectivity but it's only when you use a browser that you have a problem then it is almost certainly a DNS problem, something I mentioned earlier. Ping the router or the other PC's IP from your problem PC. If you are successful then its not a stack, NIC or cabling/hub/switch problem. Its software and highly likely a simple resolution problem. Manually assigning your DNS data may solve it. May not but its definitely one of your steps in troubleshooting host name resolution issues.

 

[Killrose]

I do see the other PC in Network Neighborhood from the problem PC, but I have never gone as far as set them up to transfer files, ecetera. To ping the router, or working PC, I assume I have to do that thru the Browser address bar?, which I can't do on the problem PC. Or I guess Network Neighborhood brings up an address bar. Sorry, this is new territory for me.

I will try your sugestion and manualy set up the addresses in the network properties. I'm wondering if for some reason I have a re-direct somewhere thats causing this problem?

Thanks for your help and I'll try it when I get home.

To ping, just open up a command prompt and run ping
e.g.

C:\>ping 127.0.0.1

Pinging 127.0.0.1 with 32 bytes of data:

Reply from 127.0.0.1: bytes=32 time<10ms TTL=128
Reply from 127.0.0.1: bytes=32 time<10ms TTL=128
Reply from 127.0.0.1: bytes=32 time<10ms TTL=128
Reply from 127.0.0.1: bytes=32 time<10ms TTL=128

Ping statistics for 127.0.0.1:
Packets: Sent = 4, Received = 4, Lost = 0 (0% loss),
Approximate round trip times in milli-seconds:
Minimum = 0ms, Maximum = 0ms, Average = 0ms

 

[Killrose]

Ok, thanks, i'll try that as soon as I can get home.

 

[ktwebb]

mgpaulus gave you the loopback address which is fine. It will tell you if TCP/IP is functioning properly. Next ping the IP of the NIC on the machine you are sitting at. Next ping either the router or another PC's IP. If those are all successful then your Stack, NIC, and hardware (cables hub/switch etc..) is funtioning properly.

 

[Killrose]

Ok, tried the loopback ping test and that's good. Also pinged the gateway and Primary DNS with no problems from the problem PC. I pinged the router as well with no problems, so whats going on here?

 

[ktwebb]

For the third time, DNS. Manually assign DNS IP's on the trouble machine and see if that clears up the browser host name resolution issues. It's not an absolute but its a decent bet. If it's not that, I would make sure you don't have some browser function checked incorrectly. Like forcing it to look for a proxy server or something like that. You could try just renewing the IP data from the troubled machine. ipconfig /renew from a dos prompt, or whatever the graphical equivalent is in 9X/ME. That might reset the DNS but i'd try manually inputting the DNS IP's, taken from your other machine that is working. Many times, its just the router's IP, or the same IP as the gateway.

 

[Killrose]

Woops!! oh yea, the DNS thing, that's next.

 

[Killrose]

Ok, tried to manualy asign DNS, and that did not work, but I will try some of your other ideas when I have more time, thanks.

 

[ktwebb]

I didnt even think of it but if you put the IP of a website in the URL window and that works but not the host name, say instead of www.yahoo.com, put 64.58.76.225 and if that works its definitely a host name resolution problem. If it doesn't work then you may have to start from scratch. You said you removed and replaced several times but its a little unclear if you meant just the physical adapter or the actual TCP/IP stack. If you didn't remove the stack, you may try removing IP from the network properties, reboot, re-add and then reboot again. May work. May not. Worse case scenario you may need to reload windows but that would be a last straw scenario for sure.

 

[Killrose]

I think where I screwed up origionally was that I did'nt remove the NIC (or my sound card) before shuting down and removing my old motherboard. Then when I booted up with the replacement motherboard it asked me for the drivers, ect.

I noticed when I tried a spare SMC Nic that I have, that even though I removed the Linksys nic through device manager, shut down, removed the actuall Nic card, re-started, booted into safe mode and did'nt even see any other network devices, that when I installed the SMC, booted up, installed the software for the SMC, that a Linksys Nic showed up in in Network properties, and I was floored by that one.

I'll try removing the IP stack before the actual Nic. I think if you remove the Nic first, the IP disapears.

I'm going to try the SMC Nic again, maybe i'll smoke out some more crap that I can then delete.

 

[Killrose]

Well removing tCP/IP and the Nic, then installing my SMC Nic did not work. Maybe i'll try to reload IE or something.

 

[Killrose]

Well removing IE6, and installing IE5.5 did not work. This is weird, I have file sharing fuctionality, can ping the router, my ISP, ect., but can't get MSN.com, or game online.

 

[Killrose]

Still trying...

 

[Killrose]

Still trying. Can share files between comps using network neighborhood, can ping the router, the DNS primary, secondary in command com with the problem PC, still cannot access the internet with the problem PC.

 

[mgpaulus]

Can you do an ftp to ftp.microsoft.com? Can you do an ftp to 207.46.133.140?

If not, then you might not have your gateway setting correct. Do a winipcfg /a on both machines, and then check them against each other. Your gateway setting needs to be pointed to your router. Since it is on a different tab, it might have been overlooked/missed.

Maybe you could dump BOTH of your winipcfg /a outputs here, with a note as to which is working and which is not.

Hey Killrose, I had something similar to this a few months ago. I think I was told to run winipcfg and then click on the "release all" and then "renew all" buttons. Anyway, it corrected my problem. Sorry if somebody already mentioned this. I didn't read all the posts very closely. Good luck!
