And is this correct? Do you have a 10MBit connection?

 

it support both 100baseT and 10baseT.

So you try to ping to yourself here. This does not work. You have to ping to a
different target (PC).

 

Yes i tried to ping the Host PC (i.e) 192.168.13.240. But still i am not getting reply.....

Possibly a PHY configuartion problem. Did you check if you soldered the
correct resistors and condensators? Is the power-supply ok?

 

if I do the PHY loopback by enabling the bit 14bit in the BMCR. i am getting the reply. Still you suspect PHY configuration problem.....or do i need to do anything at MAC side......
