I have a Linksys E3200 router and wanted some additional information about the proper settings. The router is currently working but I have some minor issues. 1) I have only 2 devices that connect with the 5.0 GHz and both of the devices are N so in my manual setup should I keep the setting N only or mixed and I have the channel as Auto DFS? Is this best? 2) I have both 2.4 & 5.0 GHZ set at channel width 20 or 40, is this best. My other problem is somewhat difficult to analyze. I have the 2 networks (2.4 & 5.0 GHZ in my home and then there are a couple of neighbor who have newtorks which show up on my wifi list. Most of the time everything is fine but every once in a while all of the networks (including mine) disappear from the available networks and later they "comeback". Can anyone gove me any insignt into this situation?
