Let's try: Diagnosing the router...

Yah-Der-Hey (Wisconsin)
yep. My little escapade didn't work. I set all the comps to static, and everything went dead. No ping reply, no google ping reply, no internet, no reply from other computers, and yet, I could transfer files...so should I just hook it up to my computer? What port? Is there anything i can really do?

ipconfig /release
then this command
ipconfig /renew
see if that works for you
entr0py: I'm having a lot of trouble understanding what's going on and your questions aren't very clear. Your little escapade.. was there a thread about this earlier?
edit: I think I found it, time to read...
What you said about transferring files but not being able to ping is pretty troubling, though. Were you using Windows samba networking to transfer? Between which computers?
And what I did, was setup ICS on the dell, while my bro's computer was still set on dynamic ips. Then i changed it. I prolly should've done one at a time, but i changed my bro's and also disabled dynamic dhcp in one fell swoop then hit 'Apply', and that's when it all went downhill. Tried resetting the router and nothing works...
//EDIT: What I don't get is that I can transfer files but not ping the other computers?! well, that may be due to it putting it on dynamic...i'll have to do some more checking. But the htm config page won't work, and the router won't respond to a ping request, either...
What model is your router btw? Mine used to do that but now it works pretty well.
Right.
Ok... so you switched the computers to static at the same time as setting up ICS? What happens if you set them back to DHCP? Also, is the DHCP server on the router still enabled?
Anyway, so now you've got 3 comps on the LAN and the cable modem on WAN again? Well, then you might not be posting... 2 comps with the router separate from Dell and modem?
So the first goal is to get to the router's config page from one of the computers connected to it, right? At this point I'd keep it clean and do this:
Power down the router
Select a computer (or do this to both).
- Enable DHCP (Obtain IP address automatically, and Obtain DNS settings automatically)
- Shut down
(If you chose not to do this on one computer, disconnect it from the router)
Turn on the router and then reset it to default settings (unless there is a good reason not do do this) - there should be a small hole or button to use a paperclip on
Power up the computer(s)
Check whether it has an IP address (command prompt -> ipconfig)
If it does, try navigating to the router's config page. If you reset it the user/password will be the factory default
Oh, and if you want to do this with the cable modem connected to the router (which would be fine) make sure you reboot the cable modem because it won't work if you don't.
I don't follow exactly what connections you're talking about. From what?
So you couldn't use the Internet connecting computer->router->modem?
How about some more command prompt. First do ipconfig and see what the Default gateway is (please report this). Then try pinging that IP.
1) Is there anything visibly wrong with the router? Is there a light on for WAN, LAN, and Power? Do they flash to show activity? (okay that was a few questions)
2) Are you connecting the cable modem to the router when you try it, and rebooting the cable modem?
From what I've seen I'd say something is probably wrong with the WAN port but it could be the DHCP server or a LAN problem- there is as small chance a different LAN port would yield a different result. We may test to see if DHCP is the problem by setting a static IP.
Nothing visibly wrong. As I said, All I did was disable DHCP and set the two comps to static in the same move. Lights all work. Shows activity. And everytime I put in the modem / pc, yes, I reset the modem as otherwise it won't work. File sharing seems to be working. I don't suppose it's possible to reflash the bios if I can't access the config page?
But I'm curious how you can transfer files... you can do start->run and type "\\computername" and connect to another computer connected to the router? What happens then when you go to the command prompt and type "ping computername"?
Pick a number to set your IP address to, 192.168.0.x (should be between say 110 and 200)
Subnet mask should be the default which is 255.255.255.0
Default gateway (this is the crucial one): 192.168.0.1
I think you're then required to set DNS server, just put in the first one as 192.168.0.1.
After doing all that, and checking with ipconfig to make sure it's set, can you ping the router and/or access its web interface?
Okay, I don't know if it will work. The issue of duplicate IP addresses is quite a big one and affects both potential setups - computer on LAN and computer on WAN. So the best we can do is try it. I can also look it up if I have a chance. If this doesn't work perhaps you should just buy a switch or hub since that is much much more fail-safe with ICS.
I guess we'll try LAN first - all 3 computers connected to a LAN port of the router (hopefully DHCP is disabled on the router since it hasn't seemed to be effective.. check that if you can). Since the Dell should already have an IP address of 192.168.0.1, the static IP arrangements can stand. If this doesn't work pretty fast, try setting the other two computers to Obtain IP address automatically. I don't recall whether ICS includes a DNS server, BTW, so you may need to manually copy its DNS config to the other computers to be safe.
