I have been using MikroTik routers for only a couple of months now and I have a question regarding the actual amount of bandwidth that I am seeing between two links. Here is the scenario: We currently have a bridged link with two MikroTik routers with Ubiquiti SR9 cards and a -15dbm signal gain antenna on both ends. The link is approx 15 miles and there is no LOS. The signal level is good at -75, but does fluctuate to about -85 at times due to some interference problems. According to the signal level, I should be able to push 36MB (or more) across the link, but I am only seeing 200K when conducting a bandwidth test on the station side. On the Bridged side (one radio is bridge mode, the other radio is station mode) I am able to test the bandwidth at 8-12 MB. There are other factors involved, but this is the basic setup and the problem that I am dealing with.
How can I determine if this is a bandwidth problem? I believe I should at leased be seeing 8-12 MB. Thanks for any help.
