WIFI Problem, not good reception!

"Hello, I had similar problem - Wi-fi kept dropping out.

However, by lucky chance, I have found what was causing it - for some reason, S4mini can't handle both Wi-Fi and BT on. Or to be precise: If you start Wi-Fi and THEN BT, it'll work till first sleep mode.

...and since I'm wearing MiBand for notifications, BT was always on in my case..."

Here is a good tutorial "How to Fix the WIFI Problems for Samsung Galaxy Smartphone" for your reference http://www.etradesupply.com/blog/fix-wif...

Hi there.. did you find a solution?? I got several s4 and s3 to test my router and router is NOT the cause! There's something wrong in the hardware. All other phones report fine wifi (rssi) from 10 meters from router. My faulty s4 can only connect from 2.5 meters from router. Any further away it pops out. As I say I have multiple phone to test with. I got the phone tester app. Select wifi and stuff. Here it tells you the rssi dam value. This is an error I the hardware as I have had this problem with THIS phone from day one. Please respond if you got some news on this. Thanks Liz, Denmark (lisbethsighfehrmann@gmail.com)

My phone won't stay connected to the WiFi that long and then to get back on it takes forever
