WiFi connection issue. - Sprint Galaxy Note 4 Q&A, Help & Troubleshooting

I use wifi connection without issues except that when my wifi router turned off and the Wi-Fi in my note 4 still on , my note 4 couldn't connect automatically to wifi router if i turned on my Wi-Fi router again.
But: I have to turn off Wi-Fi in my note 4 before i turned on the Wi-Fi router unless that i couldn't connect automatically.
So is it common issue.
I had S3 and S4 and this issue didn't happen .

[Q] WiFi connectivity issue

I have been using Note 2 N7100 running 4.1.1 for a week now but only a couple of days ago started experiencing WiFi connectivity issue at home. The problem I have is it would lose Internet connection and then disconnects from my wifi router. When I opened the wifi menu it says my router is not in range. Turned off wifi and then on again and it connected just fine. However, after a while I lose Internet connection again and then router connection as well. In addition, my PC and other mobile devices started having connection issues. So, I restart my router and everything seems to work normal again until I turn on wifi on my Note 2. The problem reoccured again until I decided to turn off wifi on my Note 2 and so far my wifi connection is stable. I did try to use static IP and for a moment it seemed to work fine yesterday but today it messed up again right after I got home and turned on wifi on my Note 2. I also reset my router to factory setting yesterday and I don't want to reset every day.
I remembered that I did a software update at work on my Note 2 two days ago but it's an update from Samsung. I forgot what the update was for. Is there any chance to undo this update just in case it caused the wifi problem but without having to root the phone?
try to add the ip and mac address of your note 2 into the router.

[Q] Note 4 Can't Connect to Wireless

I'm not sure what my problem is. When I connect my Note 4 to my wifi it says that my network may not provide internet. In addition, it shows "(secured)" next to my SSID name. The phone then connects to the internet, but it doesn't have internet. I think the problem has to do with the fact that my wifi is being brodcasted on 5Ghz. I attached an image of my wifi settings. Does anyone have any ideas of what to change on the router or my phone? Thanks.
As pathetic as it sounds, I simply restarted my phone and reconnect to the network at it is working great. Go figure.

Q: USB tethering of WiFi connection (NOT Data connection)

Back in the days I was able to use the Galaxy S 4G and the Galaxy S2 to accomplish this.
Now if I connect USB tethering it automatically disables WiFi connection and reverts to cellular data.
If an older device did this, I would imagine the Note 4 can as well.

Hotspot Problems

Hi I'm trying to connect my laptop to the Internet over Wi-Fi using my Nexus 5X as the hotspot.
When it connects to the Wi-Fi network it says the connection is limited when I check the Wi-Fi status in windows it shows packets being sent but nothing being received?
I've tried restarting both my laptop & 5X still the same issue.
