Just got my Nexus 9 today from Google Play store UK. Everything seems working ok, except:
I cannot find any wifi 5GHz. I am connecting to my home 5GHz (Virgin Media Superhub) from my HP Pavillion laptop, MBP, iPhone and iPad. But on Nexus 9, I am not able to scan any 5GHz network:
2.4Ghz works fine though:
I have enabled all possible channels in Settings (Wifi Analyzer):
In system Settings, I have tried both Automatic and 5GHz only:
I have performed OTA updated after first time switched on device and connected to 2.4GHz network at work, didn't notice whether there was an issue on 5GHz until I got home.
So, is there a problem with the latest OTA, or simple this unit needs to be RMA?

Mobile devices don't always support all the 5GHz channels that an access point might use. Try setting the Access point to use the lowest channel, say 36 and see if that works?

Hi Phil
Thanks for the hint. It looks like Nexus 9 only able to see channel 34 ~ 48. My broadband AP has selection of 36 ~ 136, and it was on "Auto Performance" and auto selected channel 100 tonight.
Thanks Phil!

Yeah.. Only 34-48 Weird why it doesn't support more than that.

Different countries have different requirements, but often most countries only allow certain frequencies to be used outside, and other frequencies for 5GHz may only be used inside buildings to prevent interference to radar etc.
A mobile device can of course be used outside, so can end up only being setup to use much fewer frequencies than a router designed for indoor use.
Sometimes the router isn't set to the right country, so ends up using frequencies it shouldn't really be using with the mobile device correctly set so ignoring those frequencies or the other way around. 5GHz is a lot more complex for what frequencies can and can not be used, see here http://en.wikipedia.org/wiki/List_of_WLAN_channels and the chart at the bottom, you'll understand why 5GHz devices sometimes don't see each other, it's a lot more confusing than 2.4GHz.

Using 5ghz wifi
Hi
To use 5ghz have you tried configuring from WIFI from settings - tapping the three dots next to the magnifying glass - Advanced - WIFI Frequency band.
It gives you the option of selecting 2.4 or 5 or both.

i had the same problem! Thank you so much for the fix!
You should be able to use channels 149-161 as well, it's the channels in between that are set aside for DFS and radar, so many devices don't support them.
Working fine for me on Channel 153 with a Nighthawk R7000.

its suposed to work check if your router router chanel are setup correctly
Got mine to connected on the Virgin Media Superhub by changing the channels as suggested. Can confirm it works but very unstable and keeps dropping connection.
I got the same problem.
I got the same problem! I bought my N9 on Nov 11 and used 5GHz without problem until today. In the WiFi Analyzer suddenly can show 2.4GHz only. I have reboot and clear all WiFi App cache & data., still cannot show.
Even connect to 2.4GHz, it took long time to Connect and Authenticate the connection.

Been a while, but since this is one of the top Google results, and I've been pulling my hair for a couple of hours without finding a solution online, I thought I might chime in with what I found.
If your N9 is not seeing certain 5GHz channels, what is your model, WiFi or LTE? Also, apparently there is an "international" version of the LTE one, which I just got (I'm in the US) because it was cheap, and I didn't mind it affecting certain LTE bands, but I didn't think it would affect WiFi. In any case, the solution was to simply insert a SIM card from my region (T-mobile US) and the missing 5GHz networks appeared in the list. I don't have a solution if this is happening with WiFi-only Nexus 9's though.
You need to insert the SIM after turning on the tablet. If you turn it on with the SIM inserted, it won't show the hidden 5GHz channels. You can just reinsert it, or toggle off/on airplane mode though.
I also googled to see if there was an app to change Wifi regions, but the only one I found (from XDA) requires root, and doesn't work for this particular problem anyway.
Well I have never been able to connect to the 5ghz channel until now. Finally! Changing the router to use channel 48 for the 5ghz and it is running as expected. I love fixes like this.

Do you have a Wi-Fi or LTE model? If you have an LTE model have you tried inserting a SIM card like I said in the post above? I got access to the upper channels which are supposed to be higher performance. From 149 to 161.
whats the highest linkspeed you guys are getting? my nexus 6 gets 866Mbps , i guess it dpends on your AC router specs mine is ac1750 i think
what app do i use to check what channel my nexus 9 is connected to? i think its below 36

I use netgears wifi analyzer.
I constantly drop wifi in my house. Is this just my phone or is it an issue? Tried everything and won't stay connected. Network just disappears and then connects 10-15 second later.
I have some issues also. Just bad firmware on LG side
I'd check your wifi modem, I use my LG V10 on numerous different modems, and have no problems with it. It connects to my home, alone with a few places I go to, and even when tje signal is extremely weak. So I'm not seeing the same thing
Also have issues on Wi-Fi
2.4 seems to hold connection longer than 5ghz. Luckily I have unlimited data. I have almost never used WiFi on this device due to this. The problem is both on my Asus RT router and my brother's Netgear Nighthawk router. Both with latest firmware. I'd like to have the option of a stable WiFi connection though.

I've read a few posts that suggest being sure the MAC address of your phone is registered with your router. I've come from 2 galaxies and I do feel the LG is a little more sensitive to a low or fluctuating signal. I "feel" it, but everytime I actually compare, it doesn't seem to be the case
Thanks for the advice

Tried the registering the Mac on both bands. Tried several device resets. Disconnected all other attached devices from the router. Had much hope for this. But no bueno. Still dropped connection after less the three minutes. Disabled 4G and the other nanny settings for WiFi on the V10. Just hoping for the much needed firmware update (s) for this sweet phone.
Again, thank you for the advice and your time.
Hi,
I bought the tab last friday. While playing around I noticed that Wifi does an
endless reconnect-loop when using 5 GHz Wifi. 2 GHz works fine..
Could anybody please try? Turn off your router's 2 GHz and use 5 only.
Watch the Wifi nenu in your tab.
Thanks

My tablet is connected to 5 gigahertz exclusively and has never dropped the connection. You may want to take a look at your router's wifi settings.
I have a brand new Galaxy Tab S3 SM-T820 Wifi version, and I have two wireless routers in my home. One is a RavPower ND007, the other a DLink DIR-813. Both are dual band routers. On both, I have the 2.4 GHz network and 5 GHz networks names differently. Every other device in my home - including a number of Samsung devices - connects to all four networks with no problem.
However, my Galaxy Tab S3 does not. When connecting to the Rav, it shows "Connected, No Internet", and can't communicate at all. It won't even connect to the DIR-813 at all.
It connects flawlessly to the 2.4GHz networks on both routers.
Both of the routers, and the Tab, all have the latest available firmwares/updates.
So it's definitely the Tab S3, and definitely a 5GHz problem.
Not sure how to report this to Samsung, but I'm going to try...
defenitley YES, 5G problem...

Last Sunday I forgot to turn off Wifi 5G on my router and used my Tab S3.... Reconnect each 2 seconds... Super Quality, Thanks a lot to Samsung..
And just to clarify - 5G works with the same router and my Phone S8 perfectly, so it is NOT a rouoter issue...
I've been using 5G exclusively as our SSID is 5G specific and never had an issue with WiFi. Solid connection 100% of the time. Netgear Nighthawk X8 here.

Will try to install the latest update this weekend, without any modifications. If 5G still does not work, I will send the Tab to samsungs repair-center, as it still will be covered by warranty.
Either it is a problem with modem-driver or Hardware..
But nevertheless, this is the very first device showing up this problem with 5G.
If Samsung is not capable to solve, this will be my last product purchased from this brand...
I did send my Tab to Samsung repair center in Germany. Will receive it today, but I already know that they did not find any problem, all fine..
Well - but they did not give me a detailed test-report yet... So I dont know what and how they tested..
Will return the Tab to my local dealer for replacement..
I'd like to test with a different SM-T825...
Reading this I haven't seen that you've tried updating your router's firmware. If you haven't try that too. I'm not sure if when you say "install latest update" if that's the router or the tab.

Just by chance I found out, that 5G works if no SIM inserted. And IF SIM is inserted, it MUST be active. In flightmode and then activate WIFI does NOT work..
This is very suspicious... I hope that SOON we will find a working lineage for the galaxy tab S3...
Galaxy Tab S3 SM-T820 Wifi version and dual band 5ghz
Hmm, I just updated my modem as per better speeds from Comcast, but I also need a new router that would take advantage of the bandwidth and the 802.11ac dual band standard so that I can get to the 5ghz band.
I own a Galaxy Tab S3 SM-T820 WiFi and before I get a new router, I want to know if the WiFi adapter in the Tablet would pick up on the 5ghz band with a new router. Is there any type of updates or drivers or am I okay?
Thank you,
Jon
I'm on 5Ghz all the time. No issues.
Great news !!
I asked the question after I learned about the variety with routers and especially since I found out that my laptop's WiFi adapter only supports b,n,g and that I would need to buy a USB WiFI adapter for my laptop or somehow change the adapter chip inside my laptop to take advantage of the 802.11ac dual protocol.
Thank you, Jon
I have the t825 version, unfortunately I have problems with the 5 Ghz connection.
I hope Samsung releases an update to fix the connection problem and to improve the camera

Hi, I have the T835 and I have the same problem. It disconnects 5 ghz, problem since I bought it.
Sorry, I'm wrong with thread
So I am on t-mobile, and I also have one of the routers provided to me by t-mobile (I believe it's an Asus) , and I have noticed recently that my wifi calling has been sucking big time. It cuts in and out and says I need to connect to a wifi network, when I am connected. It's like it doesn't notice that there is a wifi connection. Anyone have suggestions as to what might help?
What is your isp bandwidth (down/up)?

100 down 20 up
WiFi calling on Android is hit and miss. I wish it was as stable as Blackberry UMA calling.
I tried the old turn it on and off again on the modem and router and it seems to have helped quite a bit.
Unfortunately, I have this issue for a quite while. Funny thing wifi calling works smoothly on pixel or essential phone!
How old is the router?
The router's WiFi radio maybe showing its age by being intermittent with its throughput's strength and/or signal's strength.
Try with newer router or access point. If there is a coffee shop with very good throughput strength (this is most important) you can do a test with that hotspot.
Good day, everyone!
I recently attempted, but failed, to utilize my mobile hotspot to connect a friend's phone to the internet through the 5.0 GHz AP Band. The hotspot shuts off after around 7 or 8 seconds when the AP band is set to "5.0 GHz". For my hotspot to not automatically switch off after about 7 or 8 seconds, I had to resort to utilizing the "2.4 GHz" AP frequency.
I really want to utilize the "5.0 GHz" AP band on my mobile hotspot without having to worry about it shutting down every 7 or 8 seconds, since, although I realize that I will be limiting the bandwave to a smaller region, I will be getting better speeds for my mobile hotspot connections in return.
I read a potential fix posted on this oneplus thread (https://forums.oneplus.com/threads/wifi-hotspot-5ghz-not-working.959323/) that sadly didn't work, and provided you have ADB, the major steps outlined were as follows:
1. Connect ADB to your phone
2. Run adb shell settings get global tether_dun_required
- Take note of the value you get (I believe I got "null" the first time around)
3. Run adb shell settings put global tether_dun_required 0 - restart your phone to get 5.0GHz tethering
If it's important to know, I'm running build 11.0.1.12.DE18CB (OxygenOS) on a T-Mobile variation (DE2118) that has been rooted using Magisk.
If anybody is having this difficulty, or if anyone knows how to repair the problem, it would be much appreciated if you could respond to this thread.
Thank you very much.
Hotspot being all ****ed up and barely working is a long standing "feature" of OnePlus even on qualcomm, and Nord has definitely got the worst of it.
On my device (DN2103_11_A.20), the 5Ghz setting is ignored entirely, it always opens 2.4Ghz hotspot.
Weirdly enough, it does that even while being connected to 5Ghz AP at the same time which I didn't think was even possible. On most mediatek phones, if you use wifi connection, hotspot will insist on sharing its band - ie hotspot band is forced to the channel of the AP the phone is connected to and relaying internet from.
The 2.4Ghz hotspot on Nord2 runs very flaky (only ~5mbits to LTE connection running at 50mbits for the phone itself). Moreover, when not using LTE, but phone is connected to wifi (regardless of whether 2.4Ghz or 5GHz) that is relayed to "forced 2.4Ghz" hotspot, that wifi uplink will become flaky too: 500Mbit/s -> 5mbit/s on 5Ghz, 50Mbit/s->5mbit/s on 2.4Ghz AP. Meaning if you use your phone as range extender, internet will be severely slowed down on the phone itself, and become almost as sucky as it is for hotspot clients.
To top it all off, the issue of "disconnecting after 5-8 secs" occurs randomly for me even on 2.4Ghz, typically in AP relaying situation on same band as explained above. The hotspot toggle is not switching itself off in the UI though - the hotspot AP SSID disappears from the air, as if wisi baseband were repeatedly crashing or something.
The only workaround I know of is to disconnect from wifi, disable hotspot, enable LTE, enable hotspot, let people connect and *then* finally connect to wifi (which "reroutes" hotspot clients from LTE to my wifi uplink).
I don't see how DUN could be related at all here.
tl;dr: Don't bother with 5Ghz hotspot, since the wifi driver is so utterly broken for hotspot it doesn't matter which band you use.

Thank you for your reply ezdiy.
It is terrible to realize that OnePlus has a persistent problem with this, but considering the number of discussions I noticed about this issue (5.0 GHz hotspot not functioning), all on diverse OnePlus devices, I am not surprised. In addition, I wonder why "Nord" may have suffered the worst of such a condition.
The problem you suffer from is unusual. I wish I could assist you, but sadly, I am no expert in these things.
It is interesting, since, it appears that there are some circumstances in which my 5.0 GHz hotspot performs well (Doesn't switch off automatically after 7/8 seconds) and other instances in which it doesn't. Does anything like this happen to you regarding the phone hotspot, where it works better in some circumstances than others?

My apologies for confusion, as I missed your device is N200 (Snapdragon chip, on those hotspot doesn't suck as badly).
My device is Nord 2 5G 12G/256G (Mediatek Dimensity 1200). It's still interesting to compare notes about the hotspot bugs across diverse array of chipsets, though.
This at least hints its something wrong going on in OxygenOS itself.

I could tell where you were coming from, ezdiy, so don't worry.
At a first glance, I noticed that the OnePlus 6 and, as you mentioned, the OnePlus Nord 2 5G are both affected by the 5.0 GHz Band issue. However, there appears to be a general Mobile Hotspot issue among OnePlus devices, as evidenced by the OnePlus forums (From the OnePlus 5, to the OnePlus 8 Pro, OnePlus 9, and OnePlus 10 Pro 5G, among many others) and the OnePlus Reddit (Ex: OnePlus 7).
I'm genuinely curious as to what the issue is. It could very well be OxygenOS, as you suggested. Regardless of the issue, I'm curious as to how long it will take for OnePlus to truly resolve such widespread problems.
