I bought this once. Exchanged it once. I then threw it away and bought a different router. Everytime the power would flicker or go out, it would burn out the cable. The people at the store stated that it was probably one of the ports that was not working. I exchanged it, the same problem occured. Then, I bought a backup battery, still messed up. I replaced the cable 4 times when I had this router. When it was working, it worked well.
