large file download problem

[ydh0120]

When I try to download large size contents using WiFiClient( 20kb ), some bytes are missed. I read some issues #15 here but it was closed and it didn't work for me. The missing bytes are middle part of the contents. The end of contents are correct.

my code is here

---

    unsigned char ch;
    while ( cnt < bodyLen ) {
      if( client.available() ) {
        ch = client.read();
        sprintf(hexbuf, "%02X", ch);
        Serial.print(hexbuf);

        cnt++;

        if( cnt % 2 == 0 )
          Serial.print(' ');
        if( cnt % 16 == 0 ) {
          sprintf(hexbuf, "%d, %ld / %ld\n", line++, cnt, bodyLen);
          Serial.print(hexbuf);
        }


      } // end of available
      else {
        for(j=0;j<512;j++);
      }


    } // end of while
