I polorised the antennas to HP and have enabled nstream.Does it cost anything when i do th upgrade on OS?Is 12 megs tcp the best i can get Or is the PC based router board going to be a better option not interested in going dual nstream so please advise on best way forward. What is best way to upgrade os Using winbox.Do i loose all my settings if i upgrade? Please bare wth me as i am still learning the mikrotik products.
Thanks for quick reply
Ok, The polarization of the antennas will work either way, as long as both are on the same polarization, which one is better? Well it will depend on the RF signal around your area, to really tell which one is better a spectrum analysis may be required.
On the other hand if your radios are registering at 54Mbps; then 12Mbps is as much TCP throughput you will get. The performance of your cpu/board combination you can tell by maximizing the throughput and closely watch your cpu utilization, if it is below 65% it will do the job quite well.
Nstreme or no nstreme will depend on how your link is performing check latency (ping reply times at the link's "usual" throughput and look for the best performance and less latency, on my experience short links like your's work better without nstreme and longer links work better with nstreme, there are some examples anf threads here on the forum with nstreme2 or dual wireless cards for higher throughput.
