I am using a Picostation to repeat the resort's wireless network, from A SSID to B SSID. I am using DD-Wrt software, but sometimes on Fedora (but also on Ubuntu on another machine) I lose the connection (a question mark replaces the wireless icon) and I have to switch off  and the switch on the wireless card by software in order to connect again. I am not sure if it is Linux' fault, heavy wireless traffic or something else. Any comment??? Never lost any connection on Androd devices for example
