i had my TL-WA850RE for a year or half a year i guess. and this month i went on a vacation for 2 days and when i came back it was not working. I tried i every method possible like factory reset, reset using the button in the device & plugging out and in. nothing was working i searched google and the tp link community but the answers where reset and that answer is not working for me. all i can see in the device is the wireless light and the power light. the range light and the re light is not showing up. pls help me in this situation.
