Hello,

we have a problem with RouterOS v4. When upgrade RouterBOARD from version 3.30 to 4.X to significantly reduce the transmission rate on the cards, which broadcast in the 2.4 GHz. The 5GHz band is no change. RouterBOARD load did not increase after flashing. The problem does not affect the card manufacturer (no matter if it's CM9 or R52). If downgrade RB back to version 3.30 everything returns to normal.

It is only in 2,4GHz band.

Settings 2,4 B/G, datarate default, hw. ret : 4 (15 - no effect), client device - various vendor (Ovislink 1120, 5460, Wline exp......)

Thank you much for answer

nobody has the same problem?

Maybe nobody else is upgrading. I'm staying at 3.30 until nstream is fixed.

Tom
