What do you mean? Is there already a bug report in our bugtracker covering this issue?

No, not for Mageia. What I mean is the problem is known from always for this device.

Have you tried the fix here?

https://wiki.archlinux.org/index.php/Wireless_network_configuration#rtl8723ae.2Frtl8723be

If someone has not this chip under his hand, this bug will be difficult to solve. I am afraid that since it dates back from 2014, that means that the hardware is certainly buggy, which is basically unsolvable.

You need to make some tests by yourself in that case and let us know which options work (or work better) such that we could default mga6 to them.

In the link above they suggest that the powersaving feature of the board is screwed, that maybe something to explore. Maybe you could play also with powertop.

Cheers,
chris.

Same problem here, see https://forums.mageia.org/en/viewtopic.php?f=25&t=11589

The forum thread has some links to an alternative driver, which seems to have created an improvement for some Linux Mint users. But I haven't been able to get it to work in Mageia.

I had this problem with a friend's computer a year ago. I solved it opening it and changing the antenna connector, as it often comes with only one antenna instead of two.

Nowadays, the linux driver accepts a parameter to change the antenna :

modinfo rtl8723be
...
ant_sel:Set to 1 or 2 to force antenna number (default 0)


Please reopen this bug if none of this solutions solves the problem for you.
