Reviews of many buyers agree unfortunately: After about 2 months WLAN failures with power reset unrecoverable. Now is no longer WLAN! Bought on 25 October 2013. What will I do when a device is the price of 26, I do not know! January 15, the device working again .. in the garage had -4 ° C WLAN Repeater is but from 0 ° - + 40 ° ... specified under observation !! Rating increased to 3 stars! Unit is now operating at + 10 °. In steady state I'll increase to 5 stars because I am satisfied with the function!
