i have installed PPPOE service
and add Secret the problem is in Some Computers it works fine in the other it won't work like if no service is installed ! i can't figure out what is problem !

Please check your network interface card.

One by one test them.

all interfaces card are Ok ..
when i give Static IP every thing work fine but on the same computer PPPOE will not work
someone told me that some switches will not let PPPOE pass !!
but PPPOE work in layer 3 !!! and Swtiches on Layer 2!!

googled and find out raspppoe. Install it as a service in the host PC. Run raspppoe.exe then "query available service". It will sort your checking style.
