I have 2 iPhone 4 which are both connected to my Home Wifi Network with speed of 20mbps , router is a Time capsule 2tb. Now issue I have is 2 fold. One is that iPhone barely registers speeds on network of around 1mbps and that is being in same room as router. This issue has arisen recently , earlier I did not have any problem such a this. I checked various times speeds on both phones and same issue. Second issue is strange one. sometimes even though iPhone is showing connected to my home Wifi but still it won`t connect to Internet unless I switch wifi on it off and then on. Please help me find out why this is happening and whats the solution.
