I verified (to my own satisfaction, anyway) that my Line6 Relay G30 wireless setup kills my WiFi connection from my laptop. Just figured I would share this info, in case anybody cares (or can tell me that it shouldn't and how to fix it). My regular practice setup now is sitting at my desk with my laptop in front of me so I can run SmartMusic to play along with it. My setup is: Linksys WRT54G wireless router a couple of rooms away Dell Precision M4400 laptop with built-in wireless (Intel 5300, I think) and Ethernet connection to a switch under my desk that also has a Buffalo Airstation connected to the same router. So, I can get to the Internet from my laptop either using the built-in wireless, or by turning off the built-in and plugging into the switch (which goes through the Airstation to the same router). If I sit at my desk with my G30 transmitter turned on (and set for Channel 6 - I haven't tried any others yet), I lose the connection from my laptop and my Airstation to the router. I verified this by running Speedtest on my laptop. I can start it with the G30 turned off and see it running, then turn on the G30 and the test stalls, then I turn the G30 off again and within a couple of seconds, the Speedtest picks back up and finishes. This happens whether I'm going through the built-in wireless or the switch/Airstation route. One good thing I can say is that the WiFi has no affect on the sound coming from the bass, through the G30, to my amp. I.e. the WiFi does not cause static or dropouts on the bass sound.
