My laptop or PC cannot connect by wireless to my router

This is most commonly caused by a mismatch in the wireless security settings. |
If you are adding a new device to an existing Wireless LAN, please :
If you are creating a new WLAN, we strongly suggest you turn on the security one step at a time...Â Please
- check the wireless security method(s) you are using - i.e. MAC Address Control, WEP or WPA, SSID stealthing.Â Â
these seem correct, please try turning OFF all wireless security at
both ends, and establish the wireless security one step at a time (as
- Note that some older wireless cards
(which do not support WPAÂ encryption) can become very confused when
they receive WPA-encryptedÂ packets .Â In this situation we recommend
you use 128-bit WEP, or or replace the older card(s).
- Turn off all Wireless security - i.e. MAC Address
Control, WEP or WPA, SSID stealthing - and see if the laptop(s) &
wireless PC(s) can connect to the router and acess the network.Â Any
device which cannot connect is probably a hardware, driver, or signal
strength issue; and should be sorted out before turning security on.
the wireless devices do connect OK, you can turn ON the security - one
step at a time - and check after each step.Â If you encounter a problem
you will only have made one change, so will know exactly what to check
to fix it.
- Note that SSID stealthing, MAC Address filtering and WEP/WPA encryption all independent, and you can enable any combination.Â
WEP and WPA are both encryption techniques, and each client device can
only use one.Â Most Draytek routers also allow for some devices using
WEP and some other devices using WPA to be connected; though this is
not always reliable.
- If the wireless doesn't get a
DHCP address with NO security enabled, please capture a syslog and post
here for us to investigate further.
