You can't give up THAT easy. Here are some step by step instructions to use with your existing access point.

READ THESE INSTRUCTIONS FIRST BEFORE DISCONNECTNG YOUR COMPUTER FROM YOUR LAN. MAKE SURE OU HAVE ALL INFO IN THESE DIRECTION IN REFERENCE TO YOUR ACCESS POINT BEFORE PROCEEDING. Worst case simply plug your computer back into the hub.

1. Plug the computer you are currently using into the wavit11
2. Start Wavit11 Configuration Tool
3. Click File -> Initialize and Click "OK" to make Wavit11 go back to default setting.
4. Enter the MAC address of the wavit11 connected to your computer. (In my case 20 01 13) The wavit11 will not work if you get this part wrong.
5. Click OK on the window that says the initializtion commant was transmitted.
6. You should now see the mack address and IP address of the wavit11 in the "wavit11 wireless lan" window.
7. Click the IP address button.
8. Enter an IP address within the IP address range of your computer. With windows XP you can right click on the network connection icon in the tray to figure out the address of your computer. In my case my computer ip address is 192.168.1.10 and the subnet mask is 255.255.255.0 so I'll enter 192.168.1.188 (because I know that address is not used on my network but within the range) and 255.255.255.0
9. Click OK once you have the ip address and subnet mask entered.

10. Click OK in the dialog box that says "IP address configuration has completed"
11. Your updated ip address info should now show up in the "Wavit11 wireless lan" window.
12. Note that mode is set to "AdHoc" by default.
13. Highlight the Wavit 11 in that window (it'll be highlighted by default) and click "setup".
14. Click "Property" tab
15. Change "Operation Mode" to "Infrastructure"
16. Change the SSID to your accesspoint SSID (in my case it is 0b964), my channel is set to 1 to agree with my access point. Everything else I'm leaving as default.
17. Click Encryption mode tab and select 40bit WEP or 128bit (whatever your access point is set to) or "disable" if encrtion is not set. Since I have encryption turned on I'll type in me code in ascii format and click "write". My default key is set to "1" (not sure what that is by the way)
18. Click "OK" to the "configuration setting change has completed" window.
19. Click the "Status" tab and you should now see the MAC address along with the SSID of your access point listed.
20. Click the "Environment" tab and you should now see your signal strength.
21. Try to get on the internet. You should now be able to get on and I'm fixin' to post this message since I KNOW these are the EXACT steps to get the wavit11 to work with an existing access point.

Addtional things I'll be doing:
22. Go back to the "wavit11 wireless lan window"
23. click on the wavit 11 listed (it'll be highlighted b default).
24. Click the "IP Address" button.
25. In the IP address configuration window click the "enable" radio button since I have DHCP enabled.
26. OK and OK.

That's it, you should now be able to work with your existing access point.
