If you are unable to get closer to the router or access point, you might want to consider buying and installing an external antenna to your wireless network adapter. Many wireless network adapters are set up so that you can attach an external antenna to them, which will provide you with better reception than the built-in antenna. Check the information that came with your wireless network adapter to see if you can install an additional antenna.
3. There are two things to try:
Make sure the router or access point is turned on and that the wireless signal light is illuminated.
Reset the router or access point by turning it off, waiting at least 10 seconds, and then turning it back on.
Resetting the router or access point will temporarily disconnect everyone from the network.
If you don't manage the access point or network, contact the network administrator.
