A list of common Wifi issues # Wrong password. Wrong SSID. Wifi adapter does not support Wifi channel selected on Wifi router. USB Wifi adapter and built-in Wifi adapter both trying to run at the same time. Some audio cards interfere with Raspberry Pi built-in Wifi adapters. Wifi drivers are gradually changing from “wext” to “nl80211” standard. Kernel upgrades can break USB Wifi drivers. Unfortunately, we can not test all USB Wifi drivers prior to each piCorePlayer release.
piCorePlayer uses piCore which is predominately a RAM based system, so nearly everything is stored in RAM. If you modify or add files it is highly likely that you are doing the changes in RAM. So after a reboot your changes may disappear. To make changes persistent you need to do one of the following: add/modify files in your /home/tc or /opt directories, then do a backup—see piCorePlayer backup. The home and opt directories are already included in /opt/.
By default, after booting piCorePlayer, the boot partition is intentionally unmounted. This helps protect the partition from corruptions. The boot partition contains the files for getting piCorePlayer up and running so it is not usually needed after the initial startup. So to get access to the boot partition it will need to be remounted. For SD card$ mount /mnt/mmcblk0p1 Warning If you are not using a SD card, change path to suit your boot device.
Windows PCs can’t see the Linux partition on the SD card (or USB device). Windows will work with partitions formatted as Win95 FAT32 (LBA), so it will see the boot partition /dev/mmcblk0p1, but the Linux formatted root partition /dev/mmcblk0p2 is invisible. For all intents and purposes the SD card appears to be only 64.0M in size. If access to the root partition is required, there are 2 options: use a computer with Linux type OS.
