Why my wifi network speed is slow on Samsung Galaxy J5?
My samsung galaxy J5 has a problem with wifi. My connection is 30 Mbps. But i am getting only 4 Mbps on the device(speedtested). All other wireless devices are working fine on 2.4ghz but only the J5 has this problem. I wiped cache partition and also reset the device couple of times. I have tried changing router channels and resetting the router also. My router is tplink archer c60 ac 1350Mbps dual band. The J5 only supports 2.4 ghz band.
