Hey guys!
So I have a problem with my nexus 5.
Lately it seems as if it does not find "new" wifi connections... It connects to the one it already has saved.
If I click scan no wifi networks appear even though there are many(my pc and other phones get good signal)
I also get the notification saying "There are networks available" but when i touch it no networks appear...
Any ideas?
Cheers!
EDIT: I just tried adding the SSID and it connected fine and works great.... So the problem is the actual scanning...

You say that it happens "lately". So it worked previously? Anything change right before the problem arose? What is your phone's configuration, i.e., ROM, kernel, Xposed, runtime, etc. Have you rebooted the router? (I know, your other devices see all networks, but, what works for one may not for another)

I would suggest that the router you are connecting to is set to not broadcast the SId - simple (but not too effective) security measure.

Same problem here! I got my N5 yesterday and wifi was perfectly connecting to my router. The I unlocked the bootloader and root by using WugFresh's Nexus Root Toolkit and phone is not detecting anymore my wifi network. Phone wifi works since I see the others wifi around but not mine!:crying::crying:
I did the following but problem still present:
- powered off the router
- changed SSID on router setup
- removed security on router setup
- add manually the wifi into Nexus 5
I have no clue on what I can do more....pls help!
EDIT: solved: I noticed my router was set on specific channels for wifi, then I modified to AUTO
If i remember correctly, Nexus 5 version 4.4 had issues connecting to WIFI channel greater than 10.
I had this issue also.

Background:
A week ago, I flashed the Lollipop Developer Preview onto my Nexus 5. I am also in High School, and my school offers WiFi. When I went to school the morning after I flashed it, I was having some trouble with the WiFi. I usually open up Chrome and go somewhere basic (google.com) because the school WiFi will block everything and automatically redirect you to an authentication page, where you would sign in with your student ID and password. What would happen was I would try to connect to the open, unsecured SSID, my phone would connect to it, but would leave a little exclamation mark next to my WiFi indicator. I did some research on that and found that it was because my phone wasn't detecting an active connection, and was switching me back to Mobile Network thanks to the new Lollipop feature. Which means that when I would try to get redirected to the Authentication Page, it would use Mobile Network and successfully bring up whatever URL I threw in there. I searched some more on Google, XDA, and various other Android forums, to no avail.
So, I figured it wasn't the worst thing in the world, and decided to go some time without WiFi while sticking to my Mobile Network. After a couple of days, the WiFi issue seemingly resolved itself. I'm not sure if it was because of something I did, or whatever else. I used the same SSID, same URL for redirection, same browser, same everything. I didn't care, it was fixed. And I thought that was the end of it.
Fast forward to now:
Last night, I flashed the official stock image, straight from Google. I thought the issue I had the week prior was a bug that would've been fixed. To my surprise, I get to school, and sure enough, the same issue as a week before. I am, obviously, going to wait and see if it fixes itself again, but the issue sparked curiosity, and now I have to ask...
What would cause this?
What are some possible resolutions to this?
Is this something Google didn't think of when designing 5.0?
If anybody has/had the same issue, I would love to hear about it. Any help or tips/resolutions are appreciated.
Thanks,

Update:
I'm not sure what happened, exactly, but upon coming to school this morning, I noticed that my WiFi works and the issue is gone. Though I'm glad, I'm still not sure why this happened. Any answers?

I read here on the Nexus 5 site) that Lollypop has a problem when on channel 12 and higher on wifi. Might be your problem.
That's what I thought too. So I downloaded a WiFi analyzer and tried to connect directly to a channel 1 connection. It didn't work. I tried a channel 6 connection, which still didn't work. Any other ideas?
Sent from my Nexus 5 using XDA mobile app
I don't think you can do it that way. I think you will have to actually go into the school router and make the changes on the router. You will need password and permissions and I doubt that school will give it to you.
The WiFi analyzer I used showed me the available channels for the SSID, along with the channel number I was connected to. None of the channels worked.

Same problem. Whenever I try to reconnect to any WiFi, it shows an exclamation mark. To make it work, I have to either switch airplane mode on then off, or forget network and setup again.
This happened ever since upgrading to Android Lollipop without wiping data. I am rooted if that matters.
Any updates? Changing channels is far from a feasible solution.
I found a better temporary fix. Once connected to WiFi, you disable data until the exclamation mark is gone, and then re-enable it.
I'm still not too sure what the fix is. Like I said, time solved my issue. I am still curious as to what it is though, so any input is appreciated.

After a while, the problem reappears so I keep mobile data disabled while on WiFi. You can automate that with Smart WiFi Toggler. Problem pretty much solved.
Yup. Problem reappeared. When I try to disable mobile data and connect again, nothing happens. I still have the exclamation mark.

Here's how I do it:
Connect to WiFi > Disable Mobile Data > Surf the Internet > Exclamation mark disappears.
Android 5.0.1 seems to have fixed the issue for me.
Greetings.
I had the same wifi! problem with everyone and when i looked at my router's settings i noticed that there was no dns selected in the router. not from isp, not manually, nothing. So i just checked dns from isp and voila.
hope that helps someone.
Hi.
I noticed that after being connected via WiFi for a longer time, e.g. during work at the office and then when I go out of WiFi range and phone switches to mobile data some apps don't seem to be able to receive mobile data or don't see the connection at all. E g. Waze (shows "waiting for network") and OnePlus community app can't read contents. Chrome browser works without issues at the same time.
Only reboot fixes it.
Anybody experiencing similar issues?
Not sure how related it is, but I was having problem with my vpn. When I got off wifi it would not automatically connect and apps wouldn't have data, there were some other symptoms that I don't remember now. Anyway going to developer settings and turning on mobile data always active fixed the problem for me, might be worth a shot.
Same here

Yeap, I use nordvpn, ones I leave my house using wifi and vpn, I loose data when switching to lte.
I don't have this problem with my op6.
Thanks for your input. So it looks like it would maybe be worth it posting about this issue in the OnePlus support forum.
I just noticed default 4G network mode is not the one I used to have on all my previous devices. (See attached picture). I'll try to switch to LTE Global and will be checking whether it changes anything.
Hi,
I've a problem with my Mate 9 (MHA-L29B, 4G/64G).
I can switch on WIFI but after 1-2 seconds it will switch off automatically. No wifi networks are displayed. Other networks (mobile, bluetooth) and all other functions
are working normally.
I have already tried factory reset and wipe cache(s) several times.
I also tried to downgrade to android 8. Still no luck.
Could it be a hardware problem? Could I change the motherboard?
I already looked on aliexpress for motherboards, could I change to a mate 9 pro MB?
Many thx.

It's maybe not motherboard but WiFi antenna connection or so.
If you use a back- case, try without
While WiFi is connected, do you see a strong signal if you are close to the AP - test with some app like WiFi Analyzer
https://play.google.com/store/apps/details?id=com.vrem.wifianalyzer
Unfortunately I cannot connect to any wifi network, because no network is shown.

Hi there,
got the same issue -any solution or Idea?
i am on:
Modell:MHA-L09
Build: 9.0.1.158 (C432E6R1P8)
EMUI:9.0.1
Android:9
The problem ocured last week. (29-09-2019). I was on android 8 and upgraded to 9 in the hope of solving the problem - unfortunatly that did not work out.
Also had a look at the antennass -they seem ok.
Interesting!
I've started with the same issue.
I actually had the issue about 4 weeks ago (don't recall it following any update/issue), I turned the phone off for half an hour, restarted it & it was OK.
Then yesterday afternoon (7th Oct) it started again & nothing has fixed it. I know I had WiFi working because my phone showed I was using WiFi Calling when I made a call but shortly after that, I noticed the problem had started.
I'm on (phone is 'up to date'):
Model: MHA-L09
Build: 9.1.0.252(C432E7R1P8)
EMUI: 9.1.0
Android 9
Just noticed in WiFi settings, it says IP address is unavailable, however when I go to - About Phone > Status it does offer an address.....

Maybe the IP address in About/Status corresponded to Mobile Network.
But it may mean that you loose WLAN upon Wireless call - maybe try to test more what really happens then (eg, compare Status/About and WiFi Settings before and after the Wireless call)
You could also try with/without WiFi+ enabled under WiFi/Menu

If connected to both Mobile and WLAN, About/Status must show two IP addresses like on the screenshot (in my case they were: first Mobile IPv4 and second WLAN IPv6)

Yes sorry, there are 2 IP addresses in About/Status which seems strange as there is definitely no wifi connection - I'm struggling in different parts of my house due to intermittent mobile signal.
Turning off WiFi+ hasn't made any difference.
It won't offer me a WiFi call as there is no wifi connection.

Are the two addresses like on my screenshot, IPv4 (my first) and IPv6 (my second).
That means that you were given by the same media both IPv4 and IPv6 address
Eg, try like you are now at home by switching off WiFi and Mobile Data on, and then with Mobile Data switched off and WiFi on.
Then you will be sure that both IPv4 and IPv6 correspond to the samenetwork

Yes, the 2 addresses are similar to yours:
192.0.0.4
2a01:4c8:c:d227:800:db7e:8cfc:d77f
With mobile data off (obviously can't get WiFi to stay on after selecting), these disappear & it says 'unavailable'.
When turning mobile data back on, the addresses return (2nd longer one is slightly different).
So this means both addresses are given by the mobile signal & there is definitely a WiFi problem which has suddenly arisen & has been experienced by a few of us......?!
Factory reset has fixed this problem, so far.....
Hi Guys,
A strange one: since getting my Note 20, I noticed it won't connect to majority of public WiFis in supermarkets, etc. My old S8 was connecting fine to the same spots.
It does connect fine to password-protected networks, the issue seems to be specifically with public WiFi spots that require registration.
What exactly happens: I connect to a public WiFi, it then opens the WiFi portal asking to enter the details to register. I do that and then it closes the page and says "No Internet" and asking to disconnect from the WiFi or keep it on without internet. In some places, it won't even bring the WiFi portal for details and just says "No Internet".
My S8 was connecting fine in the same spots and these are spots that definitely have WiFi, for example, in hospitals, supermarkets, etc.
Forgetting the WiFi and reconnecting doesn't help nor "resets" the connection as it seems the WiFi app on the phone still storing that info.
Did any of you experience this before? I thought it might be because I have some packages disabled via Package Disabler but I enabled all the packages, restarted the phone to no avail.
Can't think of anything else and don't want to do a factory reset either.
I have this issue in some places too. Most notably in St Pancras Rail Station... It will instantly kick me off. I wonder if its to do with MAc Randomisation?

I was thinking the same and disabled MAC randomisation with no luck.
By the way I also live in the UK and this issue happens in many places - had it today in hospital trying to connect to NHS WiFi, then had it on train trying to connect to SouthWest Trains wifi, then in ASDA, Sainsbury's... My S8 was working just fine. Can't believe all public hotspots magically stopped working.
I wonder if there is something in the phone / Android version that doesn't work right. Or maybe some silly settings I changed. Don't want to factory reset though.
By the way, I couldn't enter download mode to wipe cache partition. I tried volume up + power key combination. Is it different in HK version?
Today I took my old S8 to the same place. S8 connects to public wifi without issues, Note 20 Ultra doesn't connect, it says no widi available. So this is definitely software issue but not sure what it is.
Did anyone else experience this?

You have to connect your phone to pc or laptop to enter in download or recovery mode.

After playing around I have found the root cause: Private DNS. It was set to 1dot1dot1dot.cloudflare-dns.com. Disabling it allowed the device to connect to a public wifi. Might be useful for the others who experienced the issue.
