I have the same problem. I click connect and my phone just almost immediately cancels the connection progress. I just got a new router from Cisco. Is that a possible problem ( the router)?
Your problem is not with your routers at all. You are however fixing the problem in a round-about way by changing the router, or the SSID, or the address on your S4.
The real problem all of you are experiencing is that the S4 does not release it's DHCP address after the DHCP lease has expired. Once your S4 is in this state of still having a DHCP address with an expired lease, there is a bug in Samsung's code that does not release the address, or renew the address, or request a new one.
The IP address is stored in a files located on your S4 at: /data/misc/dhcp/dhcpcd-eth0.lease and /data/misc/dhcp/dhcp_list
Power off the S4 completely, pull the battery, or connect to a different SSID, or make it a static address, and your S4 will work.
Only if Samsung fixes the bug with the DHCP lease timeout, will the S4 ever work correctly though.
I just don't understand how much more security you need filtering the mac address. If you WPA2/WPA enabled in your router and you have the firewall enabled in the router and perhaps some kind of firewall in your cell phone like LOOKOUT, what more security you want ?? When you filter the mac address all you are doing is making is this : Only computers on the MAC Address filter list will have access to the wireless network. Therefore, I don't think this procedure is giving you any extra security. The way I set up my cell was after activating wifi I had it scan for networks and once it found mine I imputed the password and applied the security to be used and that was it. Now the cell's mac address appears in my router as a device with permission to use my network but I am not filtering the mac. I don't feel the need to do it since it is my own network for which I only have access. I think that you are only creating unnecessary problems for yourself..... I am just saying.
I just got a Samsung Galaxy S4. As I have always done with all of my devices that connect wirelessly, I went into my D-Link software and added my phone's MAC address to the network filter list. The security settings are WPA/WPA2. When I try to connect, the phone is able to see my Wi-Fi network, and it asks for my password, which I enter. It keeps trying to connect, but then it says an "authentication error occurred." I have checked and triple-checked the password, and it is correct. I have also checked and triple-checked the MAC address, and it is correct. I have rebooted the router and the phone several times each. Any suggestions on resolving this? I am an ordinary consumer, not a geek by any means -- please state your response accordingly. Thank you!
