# Can't send large amount of bytes

## Question

Asked by laura107 on 2014-10-24 in Ethernet Chips.

Hi

I am using an FPGA to transmit and receive data to and from the wiznet, I can send and received multiple bytes, however I am having problems transmitting more than 1Kbyte of data, sometimes I get the whole thing and other times I just get part of it, before I transmit something I make sure that I have the available space in the transmitter buffer. Could someone help here please?
