A blinking power LED means that the switch is either downloading software, or is initializing which also includes running the Power On Self Test. You may have firmware issues with the switch and/or the switch is stuck in initialization mode. You may have to contact 3com regarding a warranty issue. Hope this helps. Good luck.

Power Problem with 2Wire 2701HG-B


Sounds like a startup self test. All wireless devices go through a power on self test. Does it connect? You can connect to it and go online? I rarely turn mine off, only in a electrical storm.
