One thing that is an advantage with nstreme in version 3.x is the ability to turn of CSMA. If you are in a noisy environment, that is a BIG advantage. As for throughput increase, turning off connection tracking will yield about a 5-10% increase in throughput when you are bridging (or even simply routing). You can do this with either nstreme or WDS. >handle nstreme) Or has anybody setup a link using multiple cards? I've set up many cards using the nstreme-dual function. For the most part, they work very well. When they don't work well, there were problems with the link in the first place. >Second, does routeros still not allow bridging two wireless cards >on the same board?

If you need more detail, let me know. FWIW, the bridging this way (wireless to wireless) worked in 2.9 series, too, but may have required special handling, depending on what you were doing. -- ******************************************************************** *Butch Evans *Professional Network Consultation * *Network Engineering *MikroTik RouterOS * *573-276-2879 *ImageStream * *http://www.butchevans.com/ *StarOS and MORE * *Mikrotik Certified Consultant *Wired or Wireless Networks * ********************************************************************
