hi, i m using ROS, i have setup wireless and local network with ip 192.168.0.1,192.168.1.1,and i have created bridge port: lan and wlan ,when i want to move file from local network to wireless network very slow ,but local to local fast ,anyone know why?

First thing - local to local does NOT invole the MT box unless you are transferring to/from that box. Local to local would just connect to the boxes involved directly. That having been said, the MT box will not significantly reduce the transfer speed if it is the one the files are being transferred to/from - the delay would be how many rules and how fast the MT router is…
As to transfer to/from local to wireless - that all depends on the connection speed (wireless)and how much of that available bandwidth is already being used by something else at the same time and how fast the MT box is. For example the RB500 series - even if the wireless connection was in turbo mode and connected at 54*2mbps (this is how turbo is represented in MT ROS) in TCP transfers the FASTEST you can transfer is about 25mbps… This is the limitation of the RB500. In other RB series some are faster like the RB433 and the 433AH (typically on a very good turbo connection you could get as much as 70mbps in TCP). But then you run up against how fast the wireless connection can transfer data - especially if the connection is being used by other wireless clients at the same time as you are trying to do the transfer.
Lastly - you are bridging everything together - that will cost you between 10 - 30% of your available bandwidth - that is just the cost of bridging…
You also did not post anything regarding your configuration except to say you bridged LAN/WLAN and the IP blocks… A lot more info would really be needed to give you a complete run down on what’s happening…

i use rb532a , 54G wireless card ,not in turbo mode,and do not setup any firewall or queues related to local network, i got data transfer speed about 1.3MB right now, but still far from 25mbps. thanks any help.

If you go back and read what I wrote you’ll see there are several factors that affect transfer speeds… How many clients are using that link? What is you CCQ on wireless? What is the signal level and the S/N ratio for the connection in question? What is the client (an RB 500 series, something else - what)? Like I said - we’d need a lot more info to troubleshoot your issue.

I hate waking a 2 year old thread. But I have the same question and since the original poster abandoned the diagnosis, I can not tell if my situation is normal or not.
My AP is a RB433AH with a R5h card on a 15dBi 120 degree sector and 1m LMR400 cable. My client is a RB411 with an R52 card and a 27dBi Grid antenna and a 1m LMR400 cable. I test the line speeds at 1am when the network is dead quiet.
My connection stats are as following:
Tx/Rx Rate: 24Mbps/24Mbps
Signal to Noise: ~30dB
Tx/Rx CCQ: ~95%/~90%
Ack Timeout: 29us
My situation: When I copy files to/from my house and my file server at the office, I rarely get transfer rates of more than 4Mbps
Would this be normal or are there some settings i need to change?
OK so i fiddled with my antenna and got a better signal, I’ve got 100% CCQ now.
I also found a Queue limiting the connection to 4Mbps, I disabled it.
I still have link speeds of 24Mbps, and my download rates from local network went up to ~7.5Mbps which give me file transfer rates of ~800Kb/s
This is an improvement, but there is no other limiting rules applied, is 6.5Mbps the most I will get from the connection?

First, which version of ROS are you using? Second, did you update the firmware for the board (/system routerboard [enter] then type print [enter] to see the firmware version)
Go to (winbox) Wireless menu, go to the Registration tab. Click on the ‘radio’ you are associated with. Go to the Signal tab. Now run your file transfer, what is the CCQ during this time? Go to the Statistics tab as well and see what connection rate is being used…24mbps, 18mbps, etc.
Post your resilts back here…
Problem solved. Firmware update did the trick.
