The re300 is unreliable with either 2G or 5G or both dropping out. The tether app also says the placement is at th ideal range point. Rebooting the extender some times fixes the problem but only temporarily. The latest re boot left the Extender with only the power light on. Trying to reset the device was unsuccessful. It appears that the extender has no WiFi and I cannot detect the TP link WiFi signal.
I am about to bin this item.
