Wireless With low bandwith

I have a 10 mile link and can only get 4.2 mbps Rx and 4.2 mbps Tx. i have tryed 5 GHZ turbo and nothing has changed.

dose anyone have any sugestions?

there are many threads in this forum that would be helpful for you,

to list some: low signal level, high noise, bad cabling, bad antenna, broken wireless card etc.

what kind of hardware do you use ?

I am using routerboard 500 with cm9 cards.

check cables and connectors
make sure cable is not longer than 2-3 meters
check antenna polarization and align it properly
make sure there is clear line of sight (visibility)
change frequencies / check for interference
check pigtails, are they are attached to correct connectors
check if height of the endpoints is enough

also how did you test it?

I am able to get 20 mbps with OSPF routing full duplex wireless! now my issue is the processor is at 100% so i think that is my limitation at this point.

how fast are you routers, are they Routerboards? You can also make the support output file and send it to support@mikotik.com to check if that 100% is due to the limitation of the CPU or maybe there ia some other problem (maybe a bug).

I am using Routerboard 532 and i have never done a support output before. how do i do that and is it free to send it to mikrotik?

Here are the instructions:

Thanks I will have to try that!
