Wifi support t5
If you want to get WiFi, the only WiFi SD card available for the T5 is the Palm WiFi SD card. No other WiFi card compatible.
The SD card fits into the SD slot, but the card is longer than standard SD cards, so part of it extends out of the slot. This is the antenna for the WiFi radio. Also, you must install the drivers for the card or else it won't work properly. Drivers are available for free download at Palm's site. Linux will not work either without the card, sorry.
