slow wifi with mainline firmware

[avafinger]

@thiagobucca
Can you share more info about the wifi issue?

Maybe there is a need to update the wifi firmware if there is one newer?

[avafinger]

Here is my test about the Wifi. Pinging and accessing the M2Z (192.168.254.101) from a PC Box (192.168.254.11).
I don't see anything unusual.

Check if you have another Wifi with the same IP or MAC, and ping in reverse to see if the board can return the icmp packs, maybe a routing problem?

I think the board never turns off, check the filesystem integrity.

umount an check both partitions:
sudo fsck.ext4 -f /dev/sdc1
sudo fsck.ext4 -f /dev/sdc2

i started fresh with the latest image you provided and everything is working fine now, thanks.
