After updating to Android N my N5X won't find any 5GHz wifi network.
I have reflashed radio file, also tried different ROMs, etc. any ideas? I can confirm my 5GHz network is working as other devices can connect to it.
Thanks
EDIT: 5GHz wifi network
This can sometimes happen if the router chooses (or if you choose) a weird channel for the 5GHz band. I believe I had this problem when the 5 GHz band in my house was set to one of the channels towards the end of the spectrum, like channel 161 or 165. Let me know if this goes straight over your head but you're gonna have to log into your router and check things out.
The IP is usually something like 192.168.1.1, but you can check by running command prompt and typing ipconfig and looking for "default gateway". That IP address if your router's IP. Type that IP into your browser. God willing you have a separate router from your cable modem, go ahead and log into your router. If you don't know the username and password, ask someone who does. Flip over to the wireless section so you can play with the 5 GHz settings. If you live in a congested area like a city or a neighborhood, you should set your 5 GHz band to a channel width of either 40 MHz or 20 MHz. 80 will get you the best speeds but interference will step all over your performance, so if you have a lot of neighboring wifi networks, you won't see any gains. As for choosing a channel, you can choose one yourself (which is what I usually do after taking a survey of my house to find the best channel) or leave it on auto. Auto will select what it thinks the best channel is and sometimes it might select a channel that makes some devices unhappy. Again, this tends to be the higher channels like 153-165 in my house with some devices.
Hope this helps.
Turn the GPS on and scan for wifi networks.

available channels on my router 36, 40, 44 and 48. none does the charm, also programs like wifi analyser won't detect any 5GHz network. Thanks anyways, any other ideas?

Hi all
My N7100 doesn't want to work with 5GHz WiFi at all. There is no option like that.
Event WiFi analyzer cannot switch to 5GHz and works only with 2.4GHz.
This happens regardless of any ROM or kernel I tried. AOSP, stock, CM10, CM10.1, combined...
I thing it's a kind of limitation in software. But I tried many ROMs and kernels. Do we have any radios/modems to flash separately?
Thanks
Wi Fi 5GHz on AP
I think there should be a 5GHz WiFi output from your AP also to connect with your 5GHz WiFi, correct me if am wrong.
I'm not talking about connecting to 5GHz.
The scan doesn't work...
WiFi analyzer allows to scan 2.4 or 5 GHz ranges. You can swap between two, but with my Note 2 I cannot change band, it always locked at 2.4GHz.
I'd be happy if anyone verified with WiFi analyzer is he can scan 5GHz band.
i have cisco e4200 set with different ssid for 2.4 ghz and 5 ghz. my ipad mini can detect and connect to 5 ghz one but my laptop (asus a55vm) and gnote2 cannot even detect it. updated the router's fw but no dime. so, i was wondering if the my laptop and note2 really support 802.11n at all?!?
no solution or no one even bother to connect to 5 ghz?
No 5GHz
I have the same problem I cannot see the 5GHz Network from my note 2 but I have no problem from my laptop and other clients.
Searching the web I found that the Mac Book Pro has the same problem with some 5 ghz Networks and they require the router to be on a specific channel:
channel 48.
Could this be the same problem with the Samsung Note 2?
Could it be that the radio only accept certain channels on the 5 gigahertz Network ?
I'm not at home but next week, when I go back, I will try to set the router to a more central channel like the 48.

I can see both on mine with wifi analyzer but there is no option to specify bands. apparently Samsung took that out.

In my case I can chose which bands to scan with WiFi Analyzer but then it only shows 2.4GHz networks.
Please, please, please...
Anyone? any help??

You may just be missing the button (which helpfully disappears when you're not messing with the UI). Upper left corner, there's the little Wifi Analyzer icon, just to the left of the text "Wifi Analyzer".
Poke the little area of blackness in between the Wifi Analyzer logo and the -30 dbm label on the chart.
That (normally-invisible) button toggles it between 2.4 and 5 GHz.
I can scan and use 5 GHz fine on my note 2 (my AP at home does 2.4 and 5 GHz at once, and the note 2 can connect to either one). The AP is on channel 149; haven't tried others.
@ tpeef
Thanks for jumping in. I appreciate your help!
I can see that button and I can toggle it. However I see all the 2.4GHz networks but none of the 5GHz.
In a Starbucks cafe I saw and connected to a network with "5" next to it but I didn't have time to check (with my laptop) if actually was 5GHz or just called "xxxxxxx 5".
Could it be that my 5GHz network channel is outside my device's radio's hardware/OS specs? If so, how can I modify the device's specs?

Try the lowest 5 GHz channel.

I had to change the 5GHz channel to the lowest available (36) before my phone would see the SSID.
To get Wifi Analyzer to scan the 5GHz channels tap the upper left hand corner below the icon and above the -30 dBm.

According to WiFi-Analyzer, the Note II can only see 5GHz channels 36-44.
Thanks Rusty Wedges !!!
Ran across your statement, scanned with WiFi Analyzer and seen my 5g channel was up in the 140's I think, and then went into my Asus router, changed it from auto channel to 30 (or whatever the lowest value is) then rebooted my router, and then my phone. Told my phone to forget the network, then re-entered my 5g network credentials and VOILA !
I knew it had to be something like this because when I initially set up my router I was connecting to 5g no problem. Then it just stopped. At least I also discovered I am the only person around with 5g too. Loving seeing link speeds at 150Mbps, thanks again !
I noticed something really weird today when running Inssider. I was seeing an SSID being broadcast with often no name in 5Ghz band at Channel 36. After much head scratching, wandering around to see where the signal was strongest etc. I managed to figure out that it's coming from the AFTV2 - turn it off, dissapears, back on, it's back again. I also noticed that sometimes the SSID shows us as DIRECT-EU-FireTV_d33b.
So, questions would be - why on earth is the AFTV broadcasting an SSID, what's it for, and can you change the channel at least - I don't want it taking up one of the few non DFS channels.
It connects to FireTV remote

Ah - I'd assumed it was Bluetooth - not WiFi. 5Ghz band seems odd to use as well since it's rubbish for getting through walls, cabinets etc.. Anyway, next question I guess would be - can you change the channel?

That's pretty horrible. How can they think it's OK to just take one of the few non-DFS 5Ghz channels and not give you an option to change it - that's rubbish!
AFTV2 confirmed same behavior, 5G Channel 36. This AP MAC address is duplicate of AFTV2 except for 2nd digit.
Wondering if I should move my NETGEAR Wireless AP away from the AFTV2. They are currently next to each other, interference?
Hello everyone I have an LG G7 ThinQ model number LM-G710EMW,
Now my phone started doing this thing where it wont detect and if it detects it wont connect to SOME 5Ghz AP's.
At first I noticed this on my Home Router, a TP-Link Archer C20 AC, and I thought it was the router so I factory reset it, to no dice.
Then I thought It was the network settings in my phone and I did a reset on those, to still no dice, finally I was like it must be the phone, and I factory reseted my phone, and YET IT DIDNT CONNECT.
A few days later I was visiting my parents house and they have this CHEAP NEXT 5Ghz Router, and it did connect to that one, I was like AHA, IT IS MY ROUTER. That same day I configured a UniFi AC LR AP (a $100 AP) and on that one IT DID NOT CONNECT NOR DISCOVERED THE 5GHZ SSID.
So its not my router.
I have no issues with 2.4Ghz Routers or AP's.
Any ideas?
Could be a channel issue. I've run into this in the past with other phones, where my router would select certain channels depending on the surrounding wireless neighborhood. Turns out it didn't like some channels, especially ones towards the higher end of the spectrum (Channels 161, 165). Perhaps that's the problem. If you're comfortable, log into your router at home and see what the channel width is set to (20, 40, or 80 MHz) and then take a look at which channel (or channel range, depending on the width of said channel) it's set to (most likely Auto). The router chooses channels based on how busy the the neighborhood is. So if you have a lot of neighbors with WiFi networks of their own, it'll try to choose a channel that they aren't using to mitigate interference. Select a channel or channel range that's highlighted in this picture. And I know it says North America, but I believe Europe and Japan use the same channels.
Thank you very much for the reply and a fast one,
I will try to do that then, what do you mean by highlighted?
I usually leave 2.4Ghz to 20Mhz and 5Ghz to 40Mhz.. is this ok?
Is there any better config?
Thanks,

The channels that are colored green in the picture. 36,40,44,48 and 149,153,157,161,165.

This is optimal in my experience. The 2.4 GHz band is super crowded, so having it set to a channel width of 20 MHz is the only real option. 5 GHz at 40 MHz is good, if you have a lot of neighbors that also have WiFi, this is the best channel width to select for for performance without your bandwidth being stepped on by nearby 5 GHz networks on the same channel.
Because you're using a 40 MHz channel width on your 5 GHz SSID, it takes up two channels, as illustrated in the picture I posted in my previous comment. Some routers don't go up to channel 165, so your only real choices here are 36-40, 44-48, 149-153, and 157,161. You want to try to select a channel that isn't in use by neighboring WiFi networks. two WiFi networks on the same channel can lead to worse wireless performance. The router tries to do this automatically but sometimes will select channels that certain devices are fussy about. Some routers can give you a site survey and show you the other channels in use in the area of your home. If yours doesn't do this, you can download any number of apps to survey the wireless networks in your area instead. Basically, try changing the channel selection to a different choice and see if your phone can connect.

Samen issue heren with g7
Howto fix this?
You need to dial *#546368#*710# in order to enter into engineering menu.
After this follow Field Test-WiFi Test-Ota Settings. Press Disable then Enable.
Now switch on wifi and 5ghz should be available.
Brilliant tip by valyunin. Solved my issue on lg g7 thinq. now my wifi speeds is 800 Mbps and more
Hi!!
I just bought a new tab s4, and I can not connect it to the 5ghz wifi network. It connects, but says connected without internet. The 2.4GHz network connects perfectly.
PS. Sorry for my English.
Same issue.
My tablet is TIM branded.
Same issue, it connects on 2.4ghz but not on 5ghz...
Anyone?
HI peep's mine is connected to 5 GHz and it’s working flawlessly, it’s showing a connected speed of 866MBPS!
Quick questions, did you try a reboot router and Tab S4 once connected to 5GHZ ?
Also are you using separate WPA2 PSK key ?
As some routers can’t handle separate keys, keep the Wi-Fi key same for both channels i.e 2.4GHZ and 5GHZ!
Does it get ip address from the router/dhcp server you have?
I don't have access to a 5Ghz wifi right now. Next week I'll try the tablet and I'll try everything you said. If the new tablet has the same problem of course, I hope it goes well.

See below and bands i have Separate bands!

dual stack
Galaxy-Tab-S4
device info type 5 GHz
IP address: 000.000.0000 (DHCP)
MAC address: 77:EE:00:FFD:00
I have the same problem and I noticed that it came with the Anroid Pie update! 2,4G is working fine in my S4.
I have another tablet Samsung Galaxy Note 10.1 2014 edition and 5G Wifi is working flawlessly.
Might it be software issue in Android 9?
My basebandversion is T835XXU3BSF4, kernel 4.4.153-16124683 #2 Fri Jun 14 2019.
My Tab S4 was ,finally, updated to Android 9. 5GHz working fine. Both 5GHz and 2.4GHz working fine...
All good here...
I got one coming in the mail and will report back on my success but if you don't get internet trying setting your dns manually to Google's public one for testing. 8.8.8.8 Could also be related to the channel the router is using for 5ghz.
Malcolm
Okay, so I got a new tab s4, and I have the same problem. At the second floor of my house, I don't connect to the 5Ghz wifi. I have separated bands. I tried changing the channel... I don't know what else try.

5GHz WiFi has less range than 2.4GHz, maybe the signal strength is not enough at the second level. Use the lowest frequency band available, move the base unit to a place less obstructed etc. This does not sound like a device issue.

Yeah, I know, the device issue is that all my other phones, computers and devices are able to connect to the wifi. I enabled the smart wifi and it looks like it's going better, the tablet is able to get better download speed.
My phone cannot see my 5ghz Wi-Fi network. It is connected to the 2.4ghz network ok, and I have other devices connected to the 5ghz network.
I have an Orbi Mesh system, and it only gives me 4 5ghz channels to set, 36, 40, 44 and 46. Could this be the problem? My Note 10 can't see those channels?
Mine runs fine on 5GHz, channel 149. Couple yrs ago my phone wouldn't connect to my wifi, I found out wifi router was not set for auto updates, after I switched to auto, it updated and all was fine. I would suggest you check your router settings and make sure is updated. There are programs on google that check wifi signal and show which channels your phone can see and that would be my second step. Program is called wifi analyzer.

The problem is Orbi only has channels 36, 40, 44 and 48 to selct. You cannot select a higher channel, as Orbi Mesh systems use the higher channels for their wireless backhaul. Wi-Fi analyzer can see the higher channels (153) in use (by the Orbi) but cannot any signal on the lower channels, even though my router is broadcasting on them, and I have laptops connect at 5ghz to the router. It's just my phone that can't see the 5ghz network.
I just noticed you're from Indonesia and there are some restrictions on some channels in certain countries for example look here https://en.wikipedia.org/wiki/List_of_WLAN_channels.
Sorry doesn't list your country but gives an idea how that works.
Is your phone specific for your country? If not it may have some software restrictions on those channels and could be fixed with different FW or root. If that's not the case, I'm out of ideas.
