I have here at home two Mikrotik devices set up with WIFI. Each has: * The same SSID. * RSTP bridging with WIFI andf Eth as members. * Access list with the cutoff signal below -80. The access list works well and it's easy to see the devices hop from one access point to the other instead of the device holding with a vice grip to the original but very weaker signal which is what would normally happen. The issue is that Facetime drops when this access point transition occurs. On client sites with multiple radios I haven't used something like Facetime to check signal transitions rather just wandered about with the laptop reloading web pages or playing Youtube videos with no discernible problems. Is there anything I can do to mitigate the fickleness of Facetime and presumably other real time applications like Skype and SIP VoIP when switching access points? Jason

Ooh, that's interesting. I didn't know you could do that. Sounds like you can reject weak associations? Could you post a snippet of config please? I have a client with exactly that problem - devices hang on to the original AP they associated with even unto death rather than switch to the nearby AP.

Yeah that is REALLY interesting! I often have troubles with my Transformer when i walk into the garage.. I often have to turn wifi off and back on to get it to move from the CRS109 in the office, to the CRS109 in the garage, otherwise it just sits there with spotify jittering. (And then the opposite problem when I get home - my iPhone jumps onto the garage wifi when I pull up on the street, and then goes slow as heck when i walk into the house..)

Setting the access list power levels is easy. Have a read of http://wiki.mikrotik.com/wiki/Manual:Interface/Wireless#Access_List In winbox go to Wireless->Access List Set the first rule to allow Authentication and Fowarding (ticked) for power levels -80..120 . Set the second rule to have Authentication and Forwarding both unticked in the ranges -120..-81 . On the main Wireless tab make sure Default Authenticate and Default Forwarding are unticked. The levels correspond to the dB signal levels you see registered devices showing. You might have to adjust the cutoff level to -76 or -78, You need to experiment and find a balance. Don't make a typo and have overlapping ranges like -80..120 then -120..-80 as you will end up tearing your hair out. On 18 July 2015 at 13:45, Damien Gardner Jnr <rendrag@rendrag.net> wrote:

Hi Jason! Unfortunately, what you are seeing is the transport layer timing out the connection before the wifi has managed to re-negotiate the link. Since this is a client behaviour setting, there is nothing that can be done about it at the network infrastructure end, only at the client side AND server side. It may be possible to get some relief from this problem by increasing tcp time-out on the client - e.g: https://www.google.com.au/?q=tcp%20increase%20timeout Since either client or server can potentially time-out the session, even a change to client time-out may not help at all if the server is the end responsible for terminating the connection :-/ I had some correspondence with MikroTik software development team about CAPsMAN system before it was released, and there was some indication there about implementing some kind of managed hand-off between managed devices. That kind of feature will allow the target AP to take control of the session by masquerading the MAC address of the original AP which should result in a truly seamless roaming experience similar to the 3G/lte behaviour. There has been no official work of potential release of such that I am aware of, so when (or IF) this will be released is a matter of pure speculation :-} Cheers, Mike. ---------------------------------------------------------------------------- -------- Why Choose DuxTel for all your MikroTik needs? 10 good reasons: http://duxtel.com/why_duxtel ---------------------------------------------------------------------------- -------- Follow our tweets for news and updates: http://twitter.com/duxtel

I have here at home two Mikrotik devices set up with WIFI.
Each has: * The same SSID. * RSTP bridging with WIFI andf Eth as members. * Access list with the cutoff signal below -80.
The access list works well and it's easy to see the devices hop from one access point to the other instead of the device holding with a vice grip to the original but very weaker signal which is what would normally happen.
The issue is that Facetime drops when this access point transition occurs.
On client sites with multiple radios I haven't used something like Facetime to check signal transitions rather just wandered about with the laptop reloading web pages or playing Youtube videos with no discernible problems.
Is there anything I can do to mitigate the fickleness of Facetime and presumably other real time applications like Skype and SIP VoIP when switching access points?
