I am in Malaysia. After setting up DSL-2750U Wireless N ADSL2+ 4-Port, all the pc or notebooks connected directly to the 4 ports can access the internet.
If I set wifi security to OPEN, all my notebooks can connect through wi-fi to the internet
However, when I set security to WEP (128-bit), none of my notebooks can connect through wi-fi.
I tried changing 802.11 mode and Channel numbers. Still no connection.
Can anyone help? Thanks.
