Macbook Pro WIFI (late 2013)

Hello,

since one week or so, my WIFI connection has weird hick-ups: After few minutes of connection, the network speed gets slower and slower until the wifi eventually disconnects. Reconnecting to the WIFI works most of the time, resulting in fast network-speed for a few minutes until it drops again... Sometimes though, after a WIFI connection-break, NetworkManager doesn't list any available Network SSIDs and I have to reload the wifi module to be able to connect to my WIFI:

sudo modprobe -r wl && sudo modprobe wl  

Here is the dmesg output which I get during this weird wifi behaviour

Do you have any hints on how I can debug this? Especially this 1-bit-swap in the mac-address of my wifi station confuses me:

[24392.493656] ERROR @wl_cfg80211_get_station :
[24392.493658] Wrong Mac address, mac = e0:28:6d:07:ae:ec   profile =e0:28:6d:07:ae:eb

Looking at my FritzBox settings I noticed, that it has 2 WIFI chips:
E0:28:6D:07:AE:EB for 2.4GHz WIFI
E0:28:6D:07:AE:EC for 5 GHz WIFI

I'm greatful on any advice you have for me on how to debug this error.

Thanks in advance
