Hi, i have a strage problem with my SDIO WiFi Module..... After a boot of android the module gets a connect and runs stabil for about 30 seconds after that the connection aborts and i am unable to reconnect.... Now the strange thing.... if i touch the hybrid chip with my finger and let my finger in place the Wifi is very stabil and runs fine. I have also mounted a little aluminium heatsink on the top of the hybrid an my wlan is also stabil. But after 30 secs usage its impossible that the chip overheats. Any Ideas? Grounding problem, or heat problem? Yours Andreas
