At home I have a 2.4ghz and 5ghz Wifi network setup.
My S4 is always connected to the 5ghz and has never had any problems. My partners iDevices are also connected to it.
The other day when I got home I noticed that I kept getting the error 'Your internet connection is unstable' and couldn't use the 5ghz if I wasn't directly in front of the router. No settings had changed, no updates etc. It will discover and connect to the network but it won't load webpages or anything.
There is no new firmware for my router, I have tried all the different channels, and have even reset the router, and as a temporary fix I've only been using the 2.4ghz network. My iPad still works fine on the 5ghz anywhere in the house, and my partner has had no issues.
Has anyone else had this problem, or does anyone have a solution?
I'm running the stock 4.3 on the phone as I haven't even tried flashing it.

did you changed some wifi settings on your phone ??
cos if that happens you have to match the settings same both on pc{ of router } and phone
even if you are sure that you haven't changed anything just make sure and check the settings again
I've researched for any past issues on this topic but couldn't find anything similar.
I live in London and use Asus AC68U, I have connected my Note 4 (N910C) and Tab S fine on both 2.4GHz and 5GHz, but never checked whether this is connected on N or AC. The Channel setting on the router is left on Auto, and I've labaled the 5GHz SSID to have a "5G" at the end (eg. 2.4GHz SSID: "My WiFi" ; 5GHz SSID: "My WiFi 5G")
Then flew to Indonesia bringing along the AC68U, reset and reconfigured the Router to be used there, I have also configured an N66U as an Access Point (not repeater). Now my Note 4 cant' even see 5GHz anymore, even though wireless configuration is exactly the same as in London (except the WiFi SSID and password). I then found out a way to know which 802.11 speed my phone is connected to (by doing the #*0011# thing), and turned out it's on 802.11N 2.4Ghz.
I then went to the N66U (out of Radio range of the AC68U) and I still cannot see the 5GHz SSID. So I took out my Tab S 8.4, switched WiFi on, lo behold, 5Ghz is visible and able to connect to both router seamlessly. Checking the connection type, the Tab S is on 802.11AC Ch. 36 Frequency 5180Mhz, WiFi Power Save Mode On, link speed 866Mbps, to the AC68U.
My Dad has a Galaxy S5, it also cannot see the 5GHz SSID, but is at least connected to the 2.4GHz 802.11AC.
I have changed channels manually on the router but still can't see 5GHz from the Note 4, also switched OFF the WiFi Power Save Mode.
So the question is.... does my Note 4 N910C even have AC? And what is going on with my 5GHz band? Has anyone seen this problem before or point me to a thread you've been to?
I've got the n910c and connects in ac on 5ghz fine. I have a netgear r7000 running ddwrt. Has it ever worked for you ?

I also have the 910F and a Netgear R6300 with DD-WRT.
It took some configuring. But i expect this has something to do with the preset ups for using your router in Indonesia.
itll probably;y work when you get back to wherever you live.
Thanks for the replies.

5Ghz has worked for me in London using the same Asus router that I used in London, but I'm not sure if my Note 4 ever connected as AC.

Well, I brought the AC68U I used in London to Indonesia, the phone was connected on 5GHz on this router when it was in London, but somehow it can't even see the 5GHz SSID now in Indonesia.
I think I need to reset the modem and WiFi module somehow, been searching the web on how to do that but haven't found it yet.
Other devices that are currently able to connect to 5GHz and/or AC:
Galaxy Tab S: Can connect to 2.4GHz + 5GHz on AC
Galaxy S5: Can connect to 2.4GHz AC (Cannot see 5GHz AC)
Laptops: Can connect to 2.4GHz + 5GHZ N
Added Info: Tried WiFi Analyzer, Note 4 still cannot see 5GHz signal while the Tab S can.
Did you put in a local SIM? The phones may be respecting local regulations regarding frequency usage that the other devices don't, as they don't have a SIM giving them locale. I'd be curious what would happen if you put in your London SIM.

Yeah I'm using local SIM, but when I arrived still with my Voda UK SIM in the phone, the existing N66U Router (before I turned it into Access Point) was transmitting both 2.4GHz and 5GHz, my Note 4 couldn't see it. I thought I had switched off 5G SSID but when I checked, it was ON. Very sure something is up with this Note 4.
I removed the SIM card and inserted it to my LTE Tab S, switched it on, switched WiFi on, connected to 5G just fine.
I'm gonna try re-flashing the same stock ROM. This phone and the Tab are all Non-Rooted btw.
Solution: Don't set the frequency to "Auto". Manually choose the frequency for 5 Ghz, preferably to something low such as channel 36. This worked for me. I haven't tried with any other frequency though. Someone mentioned online that it might be due to Android phones not supporting DFS frequencies.
Good luck.

I just installed dd-wrt on my netgear r7000 and my n910h stopped seeing the 5Ghz band after that.
With r7000 stock firmware everything is fine.
Could you please tell me what's your dd-wrt settings for the 5Ghz band?
My N4 is no longer able to detect my home network. It detects my neighbor's network and several other networks, although it cannot connect to any other network. When I try to connect to a detected network, it just says "Saved". My home network is working fine and several other devices in the home are connected to it. In fact, my wife's N4 is still connecting with no issues. I have tried rebooting the phone, rebooting the router, telling the phone to forget the network, changing the channel on the router, no success. Running version 4.4.4.
Any thoughts on what might be wrong or ideas for a fix?
Thanks,

You haven't inadvertently switched the WiFi frequency from automatic to 5GHz have you? It's just that I had a similar problem and that's what had happened.

Both tablets are running stock Android version 5.1.1 build LMY49J
I'm just using them in my house to monitor some security cameras. That's basically all I use them for. The WiFi they both connect to comes from the only router in my house. I've always had that router (Asus RT-AC66U) setup with a different SSID for the 2.4GHz and the 5GHz.
The first Nexus 10 I bought used about a year ago and it has been able to connect just fine on both the 2.4 and 5ghz signals.
The second Nexus 10 I just got off of eBay about a week ago and it cannot connect to the 5ghz wifi signal. I thought it initially did because that's the network I chose to connect to when I first set it up and it was working... though the SSID is different, I do use the same wifi password on both of them. I don't know if it can recognize that and just switched to the 2.4GHz SSID or if I was dreaming that it ever worked at all on 5.
Anyway, it's definitely not connecting now. It will just say "Obtaining IP address" and never connect to the 5GHz. It has no issues with the 2.4 signal though.
I had searched and found a lot of threads and tried many of the different options suggested like switching my router to only broadcast on certain channels, etc.
I'm just wondering if there is something I missed or if it's more likely that there is something wrong with the hardware on this "new" tablet I just started using.
Hello Everyone.
I've got a problem with my WI-FI in my V20 that doesn't allow me to connect to 5GHz at all.
I'm in the UK with a virgin media super hub 2, I also tested it with a TP-Link C2 which is the one upstairs and nothing still. I know it's not my router as I have about 6 other devices which connects to 5GHz perfectly fine, so I know It's a problem with this device.
I have done everything I can think of to try and get it to work as well. I removed all security from the router. I tested it with another router. I used a WI-FI analyzer to see if the device picks anything up but unfortunately it doesn't find anything at all while my PC next to it can pick up 4 to 5. I also changed the channels of the WI-FI and still nothing except that it seen a few high frequencies which I couldn't connect to and the few that I did it doesn't connect to the internet at all. I've also reset the device, and updated the firmware. Still nothing has worked.
This is my 2nd V20 as my first one had the WI-FI problem as well and I hoped I just unlucky with that one and the replacement had exactly the same problem.
I brought it from ebay by the name of eglobalcentral-gb. They quickly got in contact and everything. Perfect communication. The 2nd device was also from this person as well.
The phone is also the H990DS duel sim version.
Thanks Ben
