@TP-Link huh? i thought it can go much further. The house is not large its just 1-2nd floor i wish it can go further tho

@TP-Link i only have 1 E4. When the wifi is 5-10 meters its strong when it comes to 15-20 meters the wifi becomes slow. I dont remember my original firm ware

When i updated the software the range got shorter and the further i go the weaker the wifi. Last update its not like that. Ther further i go the wifi still strong. I was just wondering what happen?...
