Im sure about all my configuration its “2.4 only G”.
when transferring files from my network through a wireless computer connected to mikrotik. it copies files at 1.2MB/s speed which is 11Mb/s (i tried on different computers and its still the same).
Is there any option i could do to make the transfer 54Mb/s(wireless G) ??
Check AP Data Rates.
1.2MB/s means ~10mbps, in B mode (11mbps) max speed is 5.5mbps. Anyway the speed is to low, you should have something like 20mbps (2-3MB/s)
InoX B speed depends on duplex mode.
explain
802.11B is a half duplex protocol, it can send or revive, but not both at the same time.
I know that but it seams that proggams2 don’t know that 
Read again all the posts…
No dont worry i understood, but my topic is on wireless G. Im having 1.3 1.2 MB/s transfer rate in wireless G.
How about your Tx/Rx Rates, Tx/Rx CCQ,ack timeout on both ends and P Troughput at CPE side?
