Hi, this seems to be either an issue with your router's hardware or local computer wireless adapter hardware. In order to determine which one is it do the following:
Go and check the LEDs on your wireless router to see if there are any blinking or switched off as stated in the official manual documentation for DLink products (can be found here
or here more specific
LEDS are as follows (left to right - per official user manual/doc):
- Power LED = A solid light indicates a proper connection to the power supply.
- Internet LED = A solid light indicates a proper connection to the Internet port. This LED blinks during data transmission.
- WLAN LED = A solid light indicates that the wireless segment is ready. The LED blinks during wireless data transmission.
- Local Network LEDs = A solid light indicates a connection to an Ethernet-enabled computer on ports 1-4. This LED blinks during data transmission.
Check the laptop's or desktop wireless adapter if it is disabled
and if is disabled enable it by going to your computer's Control Panel (either winxp or vista/win7) and go to network connections (in vista/win7 put the control panel in detailed view to see more options) and then right click on your wireless connection and click enable.
In a case that also the wireless adapter is enabled but you still cannot see any access points/wireless networks please go to your current wireless connection and right click go "Diagnose", this feature is mainly available in windows 7 or Vista. For windows XP, go to the command prompt by going to Start->Run->type in the box "cmd" without the quotes->Then type in the following set of commands.
ipconfig /release ---> This will refresh your wireless card IP settings/configuration to 0.
and after that command finishes, type in:
ipconfig /renew --> This will get new settings if the wireless card has problems finding an address from your router.
You can always reset your router (unplug from power supply, wait 2minutes then plug it back in)
Reset the wireless adapter (right click from on the wireless adapter shown in the network connections, disable and then re-enable it) or computer.
Thanks please let me know if you need anything else.
