D-Link DI-524 works with desktop, but laptop can't get signal

OK, if I understand:
telephone----DSL Modem--di 524--computer.
That is what you are supposed to do.
Has any configuration of these devices ever had any connectivity?
1. Is the DSL modem in "Bridge Mode"? That is the first thing I'd check.
2. Are you using the right wires and ports? There may be a DCE-DTE problem. Be sure you have used the wire that came with the DSL modem to hook it to the internet port on the DI-524.
3. What is the state of all the various lights? Do they show that you have valid connections?
4. Most of these devices can be configured with a browser. When you browse them, what do you see?
5. What is windows telling you?

You have to make the Ip changes on the laptop not on the modem.
You said you have internet acces on one computer. Then use that computer to find out the exact IP address used by the modem.
On the laptop use the exact same numbers, (IP, Sub mask, Gateway, Primary DNS)
and chek if it works.
If you want to have both computers on the Internet, simply change the last number on the IP address ONLY.

Please don't forget to rate this answer if it helps

Checklist:
* Is DHCP configured correctly?
* Connect your server and laptop to a switch (not directly with the cable)
* Can they ping each other?
* Check that the firewall is configured (or switched off if you have another FW in place)
* Default gateway should be your router, not the computers (until you have configured RRAS for example)

Do you need to see the desktop or just share folders from each other? If the latter then you need to do the following:

Use Windows Explorer and select a folder you want to share. Right click and select sharing and security.

On the sharing tab click on Share this folder. Enter a share name ( I like to enter the PC name _folder name; Rick1_Downloads)

Click on Permissions. If your ok with everyone using the PC's and Laptops having access then highlight Everyone and click on Full Control.

Do this on each PC and Laptop.

That should be it or darned near close.

make sure your wireless card is set to "obtain automatically an IP address"

Hi there!

Let me try and help you out.

Please describe your cable connections from the modem going to the router. What specific port from the modem goes into the Dlink router?

You will need a wireless router (like the D-link DI-524) to connect in yours cable modem, and use wireless internet access in your Advent 9115

does your utp cable crimped correctly? have you tested this? try to use this utp cable to your laptop if its okay then follow the instruction as what is written in the manual, i also experience like this with my 4pc's before and i found out that the utp cable i crimped was not properly done. in the case of the DI-524 this is just a plug and play you don't need to configure.

I am assuming that you have a functional LAN cable connecting the Westell and the DI 524, right? If you are unsure, replace it with a cable you know is good.

If the 524 is turned on downstream of the Westell modem, it should find what it wants. You may try rebooting the Westell and seeing if the 524 finds it, and you maybe should reboot the 524.

Sometimes, when the world gets jiggered up I have to work pretty hard to get my DI-524 resync'd to my DSL modem.
