Ralink 5390 wifi chipset
When starting without any firmware.tcz installed:
dmesg shows:

After downloading the firmware-ralinkwifi.tcz

So there is something strange going on.
I really can't see much difference between the lsmod output from before and after loading the ralink-firmware - however it needs the firmware in order to connect. Also I think the previous versions of piCore would not allow the wifi adaptors to try to scan if the firmware was not loaded.

Hi Bela
Just remembered that a guy from the squeezebox forum (where the piCorePlayer is discussed and used) stated something about two patches for the realtek driver in newer kernels: http://forums.slimdevices.com/showthread.php?97803-piCoPlayer-Squeezelite-on-Microcore-linux-An-embedded-OS-in-RAM-with-Squeezelite&p=795764&viewfull=1#post795764

Hi Steen
thanks for the link. I will make a new beta with these applied.

My statistics using 65,500 bytes long packets and beta100:
--- Code: ------ 192.168.0.1 ping statistics ---
13073 packets transmitted, 13003 packets received, 0% packet loss
round-trip min/avg/max = 24.608/37.586/633.908 ms

Atheros AR9271 chip.
Same test on ASUS laptop and 6.0rc1 gives 2% packet loss and cca. 80% longer ping time to the same AP, so RPI offers better performance, at least in this test.
