    I have inherited a mesh link issue that is being reported as slow - having a look through the profiles I notice that the a-radio profile does not have a secondary channel set (attached screenshot) does this mean that the link will not channel bond. The link is made up of two 134's with both interfaces on each connected into switch trunk porrts.

    I've downloaded the tech-support files from the mesh devices and it shows the following -

    Does the RateTx/Rx 54/54 mean that its only running at 54mbps???

    There should also be a mesh HT profile, under the mesh profile.  54 just means that is what it negotiated, not what it is configured for.

    Ahh I was looking under the regular radio profiles. It seems that HT is not enabled under the mesh HT SSID profile - I guess this is why there is an issue with bandwidth across the link.

    Also how do I determine if it using 40MHZ?

    The mesh channel will have an HT if you are using 802.11n.  It will have a + or - if it is using 40mhz channels.  At some distances outdoors, 40mhz is not always what you want to do, however...http://community.arubanetworks.com/t5/Unified-Wired-Wireless-Access/2x2-vs-3x3-wireless-bridge/m-p/137253

    I read this post while I was hunting for some info on this - the link is less than the 50m mentioned but probably further than 20m. I went up to the site about two years ago so I'm working from memory. I will bear this in mind when i report back to the customer.

    Thank you.
