I had just bought a Samsung Galaxy J7. I tried connecting it to my home WiFi and it gets connected and disconnected frequently. It works smoothly on other WiFi networks and my home WiFi works well on the devices of other members of my family. What should I do? Wifi problem... My Mtnl wifi router is frustrating me from the last one week. I use it to connect my galaxy ace plus to the internet. The porblem is that router is responding slowly while i surf the internet though i'm getting full speed of 2mbps. I also use my phone's wifi in my college and there the phone works fine and responds quickly. I tried to connect some other phone to connect with my router and the router is giving quick reply to that phone. I'm unable to find where the problem is. I tried to contact mtnl for the same but they are not entertaining me. Please help me out...
