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.
Hi all, Recently got my m5 from eBay here in the USA. I have a lot of questions but the biggest one is the tablet isn't seeing my 5GHz network. It connects to the 2.4GHz network just fine and we have a house full of other devices that connect to the 5GHz network so not sure what is going on.
To be clear, the 5Ghz network isn't even an option to select.
Model: SHT-W09
Build: SHTW09 8.0.0.151
Probably you are using a channel which is not supported? For me the 5GHz connection is working without any issues.
Try manually entering the ssid.
Try a factory reset. I have 5ghz on mine
Thanks for the idea. That worked. It was on auto channel using 149. Moved it to 40 and it can see and connect now. Thanks again!
Hi,
I have a new OnePlus 7T Pro (version 10.1.4.HD01BA) and I'm having wifi stability issues.
The wifi has micro-disconections which impact any application which needs a stable connection (ex: online games, file transfers)
The symptom is a short disconnection from the wifi network: the wifi icon on the top briefly shows a "!" to indicate the disconnection; then everything comes back to normal).
From what I gathrered from different tests, the disconnects only occurs when using wifi on a mesh network (e.g. Orbi) or multi-channel wifi router.
I have no stability issues when using 4G connection.
I also tested 2 different mesh networks, the OP7TPro Wifi is unstable.
When testing on a simple channel access point (ex: another android phone), the wifi connection is stable.
On the mesh networks which give me stability issues, my older OnePlus5 does not experience any specific problems.
I tried to wipe my phone to factory defaults but the problem persists.
How can I find out if this is related to a software issue or if my device is faulty ?
Thanks,
Hello, I realize, this thread is almost a year old. I bought this phone and I'm having the same issue!
It seems that it maybe is related to bluetooth being turned on.
Have you somehow solved this problem? I read many complaints over the net when googling, but all the suggested solutions don't solve the problem completely, the drops still occur.
The problem has been known for years and occurs not only in the OnePlus 7 phones. When we connect to WiFi 2.4GHz and turn on bluetooth, WiFi transfer decreases drastically, the solution is to connect via WiFi 5GHz if our router allows it. If not, only the mobile network remains.
Well, that's a pity, thanks for your answer.
I also noticed, that the bluetooth range is really poor with my bluetooth headphones in comparison to my previous LG V30.

Use 20Mhz channel on your router instead of 40Mhz, that should solve the throttle in speed issue on 2.4Ghz band

I first faced this trouble in my oneplua 6, so your point about this being a oneplus 7 series problem is wrong
I have an issue with my galaxy S21 that is not automatically switching between my 5GHz & 2.4GHz wifi network when in close range to the router.
I have smart connect active on my router. When enabled, the 2.4GHz and 5GHz networks share the same network name and password(only one SSID will be displayed), and your wireless device will automatically switch connection to the Wi-Fi band that provides the fastest speed.
My device stays connected to the 2.4GHz network, I then have to turn my wifi off and back on again on my phone to connect to the faster 5GHz network when in range. My S21 is the only device on my network that does not do this automatically.
Anyome else experiencing the same or have a fix for this?

I've seen the same behavior. My configuration is the same as yours. I did a little experiment. I switched off the 5GHz range on the router. All clients switched to the 2.4 GHz range. Then I switched the 5GHz range on again. But even after 30 minutes, my 3 dual-channel android devices Galaxy S21, Galaxy Tab S4 and Galaxy S6 were still in the 2.4GHz range. Then I switched the S21 wlan off and on again. The s21 immediately connected to the 5GHz range and the other two devices followed immediately. Very strange. My WLAN router is a Fritz!Box 7590.
Otherwise, I know the behavior of the devices in that the devices only search for a new connection when the current connection is broken.
Sorry for my bad english, I am German.

Hi! These are router problems. Set maximum power for 5GHz and average or minimum for 2.4GHz. Prioritize connecting devices to 5 GHz.

Can't be a router problem. Don't have an issue with any other device on the network switching between 2.4 & 5Ghz, only Samsung.

I see that a stronger signal is important for communication than fastest band. Samsung has a weaker Wi-Fi transceiver compared to a laptop for example. In my dual-band router, I made settings as described above.
The Android device alone can select the WiFi frequency range. Try to make the 5 GHz band more "palatable" to the cell phone by temporarily blocking the 2.4 GHz band in the router. Then remove the login data from the mobile phone and from the router. Make a restart from Handy. Then register the device again and release the 2.4 GHz band. Then test the behavior.
Please let us know if it helped.
Edit: Make sure to use the original MAC address of the mobile phone when log in.
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.
