Thanks for answering i will try to clarify.
First i have a router and hub downstairs wich is attached to a repeater linked to another repeater upstairs.
This is where i have my laptop connected/attached to my wireless speaker and yes its connected to router via wifi.
Also i am using a media player "JRiver" where i have configured a media library using DLNA.
Dont know if its mesh network since the "electrician" who installed it did not supply me with acces to the router!!
As i said i have 70 - 100 mbit to my laptop, works fine, but when i am checking, via an app to my speakers, it is only 3-5 mbit.
In some instances i had a lot more, restarting the router, but it hasnt done the trick lately.
I am not a network wisard but i am thankful for som input.
Regards Bernt
