Hi,

I've been on this for 4 days and I'm starting to go crazy. I was expecting an hour job. Anyway, I've plugged as D-Link DWL-700AP Access Point into a Speedstream 5660 ADSL router. The Routers DHCP server is giving the computers this:

Description . . . . . . . . . . . : IEEE802.11g Wireless PCI Adapter #3
Physical Address. . . . . . . . . : 00-0C-76-6F-EA-EC
Dhcp Enabled. . . . . . . . . . . : No
IP Address. . . . . . . . . . . . : 217.127.146.170
Subnet Mask . . . . . . . . . . . : 255.255.255.192
Default Gateway . . . . . . . . . : 217.127.146.129
DNS Servers . . . . . . . . . . . : 213.0.184.85
213.0.184.88

The only weird thing about it is that whatever computer has the IP address of 217.127.146.170 works, but one with 171 at the end won't. I've told the DHCP in the router to offer from 170 to 180, and it assigns them properly, but the internet won't work on any of the computers except the one with 170. There's a DNS server running on the router that spits this info out.

Also, the wireless access point has a fixed IP of 192.168.0.50, with a subnet mask of 255.255.255.0 and a gateway of 0.0.0.0. I don't have a clue ewhat to put these settings to, but I've tried a few and nothings worked so far.

I'm thinking that the Access Point is only accounting for one IP address, and so only one computer can use it at the same time? The NAPT is disabled on my router, so maybe that's it?

The AP has DHCP server, and I can give it a dynamic address instead of the fixed on I just mentioned.

Any ideas?

if you want to share internet you need a router. a wireless access point just provides a gateway to connect to a network wirelessly.

when you set ip addresses they need to be in the same range, i.e. 192.168.0.(1-254) or 192.168.10.(1-254)

I think you need to respecify your network ip addresses. The 217.127.146.170 looks like it is the ip address that your isp has assigned to your connection with the isp, and should not the basis for your ip local addressing scheme.

I would assign ip addresses as follows:

-Speedstream router: 192.168.2.1
-D-Link Access Point: 192.168.2.50
-Let router assign ip addresses to attached pc's in the range 192.168.2.2 thru 192.168.2.40

All of these addresses should be in the 255.255.255.0 sub mask.

You may have to tell the router about the attached access point, like its mac address -- read the manuals. Routers vary on this.

Turn Network Address Translation on in the router and make sure DHCP is enabled in the router.

Until everything is working properly, turn off all security, ie, wireless encryption and mac address filtering.

After you have updated your router (and access point) with these new address ranges, turn everything off. Restart in the order: modem, router access point, pc.

Let us know how are doing.

One more thing.

Firewalls often make initial setup of a network very difficult.

I usually unplug my adsl line from the modem and then disable the firewall, then setup and test the network, then reenable the firewall and configure the firewall to allow operation of the new network. Finally, I plug the adsl line back into the modem.

Simon, the slipstream is a router. However, it doesn't look like it is using NAT at the moment.

Bravo, Borderrose.

While you're at it, setup MAC address filtering and WEP on the wireless router and clients!

MCSE, MCSA Messaging, baby!
