I had my PS3 and Linkstation on a wired gigabit subnet because I wanted the PS3 to be able to stream HD content from the Linkstation. But I also needed the PS3 to have Internet access and the Linkstation to be accessible by wireless devices.
First, I tried connecting my Huawei D100 router to the switch but it couldn’t find any HSDPA signal. Sun’s signal is still spotty and weak in some areas and finicky elsewhere. So I guess the D100 has to be in the bedroom where the signal is strongest.
