Wireless Internet Connection Woes

[georgencopy]

:roll:

I'm currently sharing a wired/wireless internet connection between PCs and Macs with an Apple Airport.
PC#1 is hard-wired, the other PC and the two Macs are wireless.
Networking and Internet access work fine, but the Airport's top speed is only 11 Mbps.

Tried upgrading my wireless router to a DLink DI-624 and its promised 54 Mbps.
I configure the router (DSL with a static IP) and no matter what I do, I can't get on the Internet with IE.
I suspect there's a setting issue with IE, GhostSurf or my NetDefense firewall, but I've tried every setting configuration I can think of, including completely disabling both GhostSurf and the firewall application, and I still can't get online.

Any thoughts on what I might be overlooking?

Thanks.

PC#1
Win XP Home SP1 (all the latest updates)
Asus A7N8X Deluxe
1 Gig Corsair RAM
2 80 gig WD HDs
IE 6

On the router you cant set the IP to static on the outside
For dsl
Make sure you have PPPoE enabled and then you have to put in the user name and password
and you should be all set

You can't get on the internet with any of the computers, or on the Macs?

(Just a note ,I've got the same router and went through all of this, too.) If you're primary problem is on the PC, or on all the computers:

One: Make sure that you have DHCP and DNS-relay enabled on the router, and that all computers on the network are set to obtain IP address and DNS information autmatically (from the router, not the ISP - this is unrelated to your ISP's static IP). Reboot everything and make sure that your PC has now received its IP from the router (unless you've changed the range, should be 192.168.0.XXX). You can do this by going to Network Connections in the control panel, right clicking on your NIC card, choosing status, and then the Support tab.

Secondly, make sure that you don't have any proxy indicated in IE (which you shouldn't, unless you previously manually input that information previously).

Third, make sure that your PC ISN'T set up for internet connection sharing. You are not sharing a connection in the sense that Windows means: you are connecting directly to the internet with each machine, via the router (In Windows-ese, ICS means that one computer is wired to a broadband connection, and other machines are using that wired machine as an access point). When you go into "Network Connections" in the control panel, set the view to "Details" and make sure that the Status field next to your NIC card says nothing but ENABLED. If it says anything else -- Shared, Firewalled, Bridged, etc -- you'll have to disable those features. Also, make sure that there are no bridged connections and that there is no Internet Connection sub-heading present in the Network Connections window. If there are, research how to eliminate them and do so.

Fourth, if you registered your PC NIC card's MAC address for your static IP, that could be causing a conflict, such that the ISP won't allow access to the IP since a new MAC address is making the requests. Be sure that you choose to "Clone MAC address" from your wired PC in the router's setup, so that the ISP sees the router as your NIC card. This will also prevent them from noticing that you are sharing your bandwidth to new computers, since all requests will be addressed to the MAC representing your original PC.

Now then, if your problem is with the Macs, well, there could be a dozen problems (encryption protocol, IP address, MAC filtering, 802.11G only mode, turbo mode, long or short preamble problems, logging onto the wrong access point, etc). So if none of these fixed the problem, holler back.

EDIT: If your DSL is PPPoE, make sure you've followed D-Link's recommended setup for PPPoE configuration.
