To those experiencing disconnects when using wifi, check if you have channel "auto ranging" on in your router.
This is typically the default for a router and means that the router can change the channel it broadcasts on at any time which technically mean a disconnect/reconnect for active devices. Not an issue when web browsing but can cause dropouts when streaming.
So as an experiment, somewhere in your routers wifi setting will be an entry called something like "channel" that might be set to "auto". Set this to say "3" (or whatever) in the drop down list and reboot the A6.
Note that auto ranging has a purpose....in high density places (i.e. those where lots of routers are close to each other, say in an apartment complex) the router will try to select the best/least congested channel, which may change over time. This is because there are a limited number of wifi channels available so different households will share the same channel.
You can get a feel for this when you select a wifi to connect to on your device. If you see tens of available wifi connections, you are in a high density location.
Thus if you still get disconnects the reason might be because you have a large number of co-shares on the channel you selected. In a location of high congestion, even auto might not save you on occasions.
Where I am, I see only me (as an available wifi connection) but hard coding my channel fixed a disconnect issue I had with my wifi streaming simply because my router wanted to change channels for the hell of it (verified by checking the connected channel # in the OS of my PC streamer)
Also check your transmit power is at its max and that the wireless mode supports the maximum number of standards (i.e.
a,
b,
g,
n etc)
