piCore 6.0 Beta2

[meo]

Hi bmarkus!

The network problem I experienced doesn't seem to be related to the piCore. Started from a poweroff state three times in a row and I was connected to the internet as soon as X was up all three times. It must have been somekind of glitch with my network that caused the former problem. 

Keep up your good work,
meo

The network issue is related to the 6.0 distro, at least in my case. It is related to the wifi - LAN interaction.
I've did exactly these steps:
1) downloaded the piCore-6.0beta2-X.zip file, extracted and uploaded it to SD card
2) booted the Rpi and expanded the mmcblk0p2 partition via fdisk + resize2fs
3) tested the network with the LAN connection and it works well.
4) installed wifi.tcz, mc.tcz and firmware-rtlwifi.tcz via the apps manager
5) disconnected the LAN cable and rebooted
6) After startup, inserted the wifi dongle and USB Flash to store the test results
7) connected to the AP via the wifi utility

As you may see, there are great differences in the time, means that the connection is not stable and therefor it is slow when transferring some larger files.
