Networking problem

[kael]

Well, I am switching to a wireless network so everyone can share the cable internet.

The problem is I can set up the network where the computers are set together but the problem is no one can access the internet. I have the modem connected to the router and the light is on showing it is connected.

The problem is related to when I try to renew the DCHP, and it says that the IP timesout. I have been on the phone with DLINK and timewarner and no one can help me so this is all up to me or one of you if anyone can help. I do not know what other info to provide if anyone needs more info just let me know and Ill do my best to share. Thanks for any help guys. I want to get this done so the rest of the family gets off my case and stop using my computer for everything.

You using a wireless router? I had probs setting up my linksys router for my dsl (I know two completely diff things BUT...) usually with linksys routers you hook em up right outta the box and they work. So if you are using a wireless router or something of that sort call them. They had me do some wierd ass crap and I can't remember (it will prob be a bit diff since its a wireless tho). I see that you have called them tho now dohs.

Try also calling your internet service provider and get them to talk to your cable modem, it could be that the modem is sending but cant recieve I have that issue when I unplug my modem when it storms they have to do whatever they do on their end and bam i can get online.

Make sure all pc's are off, unplug the wireless router wait a second then unplug the cable modem, sit do some other things for like a min then come back plug the cable modem in, wait a bit till you plug the router in even after the lights have stopped blinking, then plug in the router wait a bit till you turn on pcs. It could be that it isn't releasing your old ip. I don't know how DLink works sooo =\ hope this helps.

Kael,
I have a couple things you can try.
1st. Turn off all of your systems and connect only the cable modem to the wireless router. You will need to connect your cable modem into the "up link" port on the router. If your router does not have a "up link" port it may have a button to turn one of your ports into an "up link or crossed port". When you connect the cable modem to the router be sure you have a link light and activity.

2nd... some cable providers require you to have a domain name in the ip settings of the system or device. Find out if you need to put a domain name in the wireless router.

Let me know if this does not work.

dont some isp's require a mac adress? you might have to change the router mac adress, im not sure if yours does, but ive heard of some of them doing this.

I was under the impression that MAC addresses can't be changed. Sure, you could switch out the chip, etc, but in general they are static. Every device has to be unique.

MAC addresses are burned into the NIC and can not be channged, however you CAN spoof them. This will require the original card being removed from all networks. You can't share MAC addresses.

Are you sure this isn't a simple mistake with the router being setup like a gateway and not a router? Also, can the wireless devices see eachother on the network ? You have your SSID correct right? Are you using Encryption (WEP) ? Do you have keys distributed correctly?

Sooo many things that could be wrong here.

Also, if you have a linsys, http://192.168.1.1 <-- gets you to the admin screen. If you haven't been here yet, go now and change the default password from 'admin' to something else.

Then go and renew your IP addy on it. Should all propergate nicely. Another great trick is to have a VPN setup badly. It kills all the other connections .. marvellous ;-)

Actually spurty i think it is setup like a gateway as when i turn on the wan and then it goes into a gateway to share connection between computers in My Network Connections. Is there a way to turn this or switch to make it work as a router?

[[gh]Spurty]

Yes, there is a toggle .. Gateway [x] Router [ ] <-- select router. You might have to do strange things on the PCs (if you run XP, it does really odd things)

Er, that sounds worse than when I first read it .. it sounds like you have XP and its doing the crazy XP sharing / Joining a Network nonsense. I can't even remember how I untangled that one. :evil:

[kael]

yeah ill have to figure this one out, it is xp im pretty sure doing that. Thanks for the info

You can "change" mac adresses by the way.

Some NIC drivers will let you put a manual MAC adresse instead of the burned one.

One of our client bought 20 brand new Asus P4S33 motherboard and we started to install them. But when we finished the 2nd one and tried to put it on the network, we always had tons of connection problem. So we discovered that all the boards had the same MAC adresses. We found out later that we could manunally put a different MAC adresses by going into system properties and editing the network card's properties.
