I receive full WiFi on my owrk laptop, however, when I connect my personal laptop I get connected to the WiFi but it says that the connection is Local Only, it will not give me Internet Access.
I have looked at the settings compared with my work laptop and they are identical.

OS: Windows XP

I'm not a techie, so I read the above exchanges and I, too, need someone to hold my hand thru this frustrating process.
First of all, I have Windows XP(32-bit processor) and have my internet connection here in Thailand thru ADSL. No problem.
Since I live in a condo building, we have Wi-fi, which my girl friend uses free, thanks to a router I purchased.
Since she left for a month, I disconnected the LAN cable and when she returned, we couldn't get back to Wi-fi.
Apparently, the Wi-fi detected by my PC is fine, no problem. But when I reconnect the cables correctly, I can't get my ADSL connection to work. The signal is coming thru fine, but I can't access any Internet sites, unless I disconnect from the router and just use ADSL.
The3 router is D-Link Model DIR-300
The modem: HUAWEI Smartax MT880 Router 1E
My Internet Connection: Realtek RTL8139/810x Family Fest Ethernet NIC
Adapter: Atheros AR500 5G Wireless Network Adapter

I will try to provide any additional information you need.
Thanks for your help.
