Question details:

I have recently installed D-Link wireless adaptor onto a laptop which is used to connect to the internet via our ADSL which is set up on our home network. It shows that the wireless link is reading the ADSL signal but keeps giving a message(when I activate Internet Explorer) that I am unable to establish a connection to the server and am working offline. I have checked my settings endlessly and can't seem to find the problem which seems quite simple!

Answer:

Possible problems and solutions:

- Check the wires and wireless network adapter
- Driver Compatibility
- Low Signal Strength
- Access Point Location
-Installing a repeater for a performance boost
- Changing the Antenna
- Install Windows XP SP2
- Network Settings: DHCP Addresses, Encryption Keys, MAC Address Filters.
