    If external high-gain directional antennas are needed, it may be difficult to align the antennas. Here are some suggestions for antenna alignment. To adjust the alignments of a pair of SMC high-gain antennas: Connect each SMC2585W-G to a computer via Ethernet.
  • Page 26 Fix the alignment of the antenna on one side. Adjust the alignment of the antenna on other side by using response time information obtained from PINGing (run PING.exe) the “fixed-side” computer. Fine-tune the alignment of the antenna until you get the best response time. Increase the data rate of each SMC2585W-G simultaneously until an optimal workable data rate is reached.
