Apologies, some extra info as requested (and some ASCII-art because I was bored!): The Laptop's WLAN NIC is connected to an AP integrated into my DSL device (specifically, it's a Thompson SpeedTouch 716WL). My server's NIC is connected over UTP to the 4-port switch also integrated into the DSL device. So basically: _____________ | | | (Intarwebs) | |_____________| | __|______________________ | ___________________| | | | | | DSL | LAN hub | WLAN AP | |_____|_________|_________| | | ____|___ | ________ | | | | | | Server | ~ ~ ~ ~ ~ | Laptop | |________| |________| The wireless AP is configured to only allow 802.11g devices and uses WPA-PSK for security with TKIP encryption.
