Slow Transfer from Connect to MK4S

Hello, 
since half a year the transfer is very slowly. It takes 30 minutes to transfer a 200kb file from prusa connect to my MK4S. I did not change the location of the printer nor the access point. I can remeber times it took only seconds and a 10MB file was transfered. Is there any known bug or anything i can do to speed up? 

 

Thanks in advance.

RE:

I suggest checking if the computers next to the printer have similar issues with the transfers.

Some things to test: reboot the access point, reboot the printer, check if any other wifi networks are nearby and are maybe on the same channels ( change to the least busy channel), check if the access point got stuck on some colliding or slow networks ( few times I saw access points loosing cables and they switched to the mesh via 2.4GHz connections on busy channels and this turned speed to a crawl, force switching to 5GHz and later cable helped).

If that does not help then seems like the module may be a culprit, then talk to the prusa help via chat.

See my GitHub and printables.com for some 3d stuff that you may like.

Pc and smartphone connection is fine, also the wifi sign on the printer shows full connection.

Do you have the binary gcode enabled?  Maybe this got disabled in an update. Assume you’ve cycled power to the printer.
