I have the Verizon Samsung Galaxy Note 3. I recently have been getting very, very slow Wifi speeds on it while all the other devices on the router have the same speeds. When using mobile data or other networks such as 4G or the network at school I get expected speeds, this only occurs on the wifi at home. Other devices include an iPhone, Galaxy Note 3, and Galaxy S4. I am stumped as to why this is caused and will welcome any suggestions on how to fix it.
