I recently picked up a Tp link ethernet switch (TL-SG1008D) to use with my telus wifi booster and a few other devices. I have run into a problem though, when I connect JUST the wifi booster to the switch it works fine. But If I connect something else such as my ps3 or optik tv box the booster stops working and my phone wont even connect to it the booster.
That in theory should work fine. The TL-SG1008D is a standard unmanaged gigabit switch so I can't think of any reason why it wouldn't work, unless there's a hardware issue. If you don't connect the Boost, but connect at least two other devices by ethernet to that switch, are there any connection issues with the connected devices?
