Samsung Galaxy S5 cannot connect/find 5ghz Wifi network

edited by on May 8th 2015, at 13:16

If your Samsung Galaxy S5 may not find or be able to connect to a specific 5Ghz wireless network, you may want to check which channel the network is operating on. The S5 has problems when trying to connect to DFS-channels (Dynamic Frequency Selection).

DFS-channels are basically every channel from channel 52 and up. Try setting your AP to a channel between 36-48 (inc.), and then try reconnecting your S5.

Trapeze: MAC-based authentication gets ignored after correct set up in Ringmaster

edited by on July 6th 2012, at 11:49

At a client running a Trapeze/Juniper network with some MX-8 controllers, a bunch of MP-371B and an instance of Ringmaster software to control and configure it all, we were working on implementing MAC-address based authentication for one of their ESSIDs. After correctly setting up the necessary policies, and AAA servers, we noticed that any client could still connect to our network, despite all settings being correct.

Baffled at this, we started to look around, trying to figure out what went wrong. My collegue finally remembered the true cause for our problem, a setting in the Wireless Service Profile.

There, the Fall Through Access was set to last resort, which basically tells the network ...

Obtain MAC address of the wireless access point connected to

In Windows, it is possible to obtain the MAC address of the wireless access point you're connected to. This is handy when you have multiple access points with the same ESSID (i.e. "roaming") and want to know which one you're connected to. This is done with the netsh CLI tool, available since Windows XP.

To do this, start a command prompt, and type in:

netsh wlan show interfaces

This shows all wireless interfaces on your system. When your wireless is active and connected to an AP, you get output similar to this:

Name : Wireless Network Connection Description : Intel(R) WiFi Link 5100 AGN GUID : f5ad6606-3b9d-41b ...
