Linksys wireless adapter communicating with access point but not with Internet

I have a wired network. I just installed a LinkSys Access Point ...installation appears to have gone ok. It is connected to my SOHO firewall/router. Then I installed a LinkSys Wireless network adapter in my notebook PC. The "signal" and "quality" status are both "very good". But it says "You are connected to the access point, but the internet cannot be found." And indeed, I can't access the internet OR any of the other computers in my network.
The SSID and WEP settings match those of the AP. The SOHO box is configured to enable DHCP on my trusted network, with address range 192.168.111.100 to 192.168.111.105.  The LinkSys AP is assigned  192.168.111.103 by the SOHO box, and I can access its settings just fine through that IP. BUT ... if I look at the settings for the adapter in my notebook, it has an IP address of 169.254.194.233 ... I have no idea how this is getting set. The tcp/ip properties are set to "Obtain an IP address automatically" ... so it should be getting an address from my SOHO box so that it's part of my trusted network ... I think ... but it isn't.
I'm very confused ... HELP!
I'm running Windows 2000 Professional; Norton Antivirus (but NOT Norton Internet Security). Important to note that for my "wired" network, all pc's are configured to just "assign an IP address automatically" and they all work just fine. And once again, the wireless pc can't see the internet OR my trusted (wired) network.
Thanks.

hi alicia1234 .... probably your LinkSys AP is configured to act as a DHCP server by default and you left it this way. Can you check for this? I'm pretty sure that's what happens. If your AP allocates an IP in a different subnet to your notebook, the router won't allow that class of IPs to get on the internet and the also you won't be able to see theother computers in "network neighborhood".  Disable the option of the AP to act as a DHCP server and all should be fine.

I can't find any setting that says the LinkSys AP is acting as a DHCP server. All I can find is a LAN setting "Configuration Type" ... it is set to "Automatic Configuration DHCP", about which HELP has this to say:

 "If the Access Point will obtain an IP address automatically from a DHCP server, then select Automatic Configuration - DHCP. If you will assign the Access Point a static IP address, then select Static IP Address and enter an IP Address, Subnet Mask, and Default Gateway address."

I'm pretty sure this is correct since the AP inself is being assigned an IP address correctly (i.e., within the range specified in my SOHO box).  

It's the network adapter in the notebook PC that is getting a weird address.

FYI .. I have WEP enabled on both the AP and the adapter; both use same PassPhrase, as required.

I read in the troubleshooting section of the LinkSys doc that the SSID and WEP settings have to be the same "on all PC's in your network".  I assume this means in the WIRELESS network?  Because my wired PC's don't have these settings, right?

my supposition was due to the fact that it seems your router is working fine , so such weird IP address must be given by the AP.
What's the AP exact model? I will try to find it's manual and see if it acts as a DHCP server.
WEP doesn't have anything to do with IPs , so that's not an issue, nor SSID
Regarding the wired PCs , they don't have an SSID, so the only thing they have to have in common with the wirelessly connected PC(s) is the same subnet, mask, workgroup and same gateway, and while all are handled by a DHCP server , there isn't much you should set.

I tried setting TCP/IP properties for a static address, and gave it an address in the range of my SOHO trusted network addresses ... rebooted etc ... still can't see my internal network nor the internet, even tho my notebook now seems to have a correct IP (192.168.111.105).
Also verified from Linksys documentation that the AP CANNOT be configured as a DHCP server.

Also note: this notebook was working fine on my "wired" network when it had a Xircom card in it. So TCP/IP and workgroup, etc, are all configured correctly.

Curiously, when I set the TCP/IP settings for a static ID (through network properties), ipconfig does report the correct addresses. However, if I go thru the Linksys utility to look at my card's settings, it still says "obtain network settings automatically (DHCP) ...
Do I need to set it in both places? (network properties AND in the card?)

On a hunch ... I set my notebook TCP/IP back to "obtain an address automatically", then powered it off.
I reset the Linksys AP back to its default settings (hard reset) ... then ran setup again and put in the same settings as I had before.
I powered on the notebook ... still got the message about being connected to the AP but not to the internet. BUT ... the IP address had been correctly assigned. So I checked if I could see the rest of my network, and I could! Then I tested Internet access and it worked.
So I guess the solution was to just reset the LInkSys AP and start over???

Note: when I checked the status of the adapter again, it said that I had successfully connected to the AP and to the Internet.

Hmmm ... strange, indeed it seems your AP is not working as a DHCP server.
I wonder who's giving the IP address in that class tho.
Try setting a static IP address in windows and using linksys's utility too.
