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.....

try to remove the battery for a few minutes...if it doesn't work try to access another wifi because your router might be the problem.
nope....
battery pull definitely didnt help. I went ahead and adjusted my network router for dual band to see if that helps at all
Also have WiFi issues
I run into that as well. It says I am connected, even gives me an IP, but all my data still seems to go over the cellular network..
Very frustrating at home.

You can use Juice Defender to automatically disconnect data when you're on WiFi... I've been using it for months and it has worked flawlessly. You can also go into Menu... Settings... Wireless and network....Mobile networks... and manually uncheck "Use packet data" (this is what allows mobile data to connect).
I had these problems also I talk to one of the geek squad guys at best buy he told me that samsung products have problems with some routers because samsung products like to keep the same ip address which my conflict with other wifi products. So I bought a new router that was stronger and assigned my phone an ip address and that solve my problem.

I installed Jelly Bean update with Sense 4+ on Christmas eve. Since then my WiFi connects but when I got to use data, say email internet or even some apps it says no data connection. The WiFi symbol is active in status bar showing full bars.
I'm hoping someone has some ideas as I'm having no luck. Thanks
I've still been working at this. I've logged into my modem/ router and it recognise my phone on a wireless connection.
I've deleted and reconnected my connection on the phone. Re booted phone and modem several times.
I've yet to try my phone on another network. But my laptop connects to WiFi ok and phone was working fine untill the update.

Sounds identical to this guy:
http://forum.xda-developers.com/showthread.php?t=2070160
Maybe you guys can continue within 1 thread?
Once again sounds like a DNS problem.
Try to prove that your handset has correct DNS settings. Also try to find something you 2 have in common with your setup. Is it the same ISP, same modem, same whatever?
Maybe ring Telstra and ask them?

I found that I had the same issue and downloaded WiFi Manager and changed my DNS/Gateway settings. This fixed the problem. I'm not too sure what may have caused the problem initially but I do know my router uses 192.168.1.254 as its address. This could have something to do with it however this is just a theory.

I changed my gateway settings, which had defaulted to something completely wrong, and can confirm it fixed accessing the net for me to, thanks!
I just downloaded WiFi manager (I'm having the same problem). Any idea what I do from here? I'm using a Netgear router, and I can still connect to the modem settings on 192.168.0.1 but that's all.

I didn't find wifi manager to be any help with the problem specifically. But changing the gateway worked for me.
Settings > Wifi > Long Press on network > Modify > Show advanced options > IP Settings > Static >
Then I scrolled to Gateway, where I removed the existing numbers and entered the IP address of my modem (not router, unless its an modem/router combo).
Leaving all other settings as they were, this worked fine for me. I don't know if you may also need to change DNS 1, or if you will have to configure a static IP on your router, but I didn't. Hope that helps

I just went all out and changed all settings, including setting a static IP. After dealing with Tech Support, "factory reset your device to isolate issue" I just wanted to attack every possibility. It seems from previous posts this may just be a Gateway issue. I should have known to long-press on the network to access advanced options. Amateur error.
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.

WHEN YOU GET YOUR NEW PHONE, CHECK WIFI/INTERNET SERVICE ON ALL OF YOUR USUAL NETWORKS.

Sounds like a local ip conflict or something else on your router side not a problem on the phone side. Did you follow the basic rule and restart the wifi router?

1 It is not my router; it belongs to my employer
2 My OnePlus 6 is here too and connected to the internet
3 All of my coworkers' phones are connected to the internet
So the phone works fine on your home wifi? It could still be the router. At my business if it has not been restarted in a while, new devices will not connect as too many ip have been given out since last restart so no more will be able to connect.

That does nothing as the router has an IP stored for that Mac address currently. It's not renewing it's lease, the router just sees it as the phone has disconnected and reconnected like it does every day you go in. If the phone cant connect to any wifi then it's a hardware issue. Otherwise it is more than likely a network issue with the router.

Sooo, I had a similar problem on Wednesday when I got my phone. During setup it wouldn't connect to my WAP (DHCP). No matter what I did on the phone it wouldn't connect. I went into my networking equipment settings (Cisco everything) and reserved it an IP. Worked. Thing is, sometimes I open an app that requires Internet, and it just spins. Or music won't start playing, whatever. I turn off then back on my WiFi and it's fine. I'm going to reboot my networking gear tonight and un-reserve the IP, see what happens. I REALLY hope this isn't a hardware issue on my phone. I'll be pissed if I already have to get a replacement.
Also, restarting the phone doesn't fix my issue with no Internet, only turning off then back on the WiFi. Might be something worth trying.

Oh yes I tried that too
I spent 20 minutes with a Google tech and nothing worked
The WIFI performance on P3 and XL is not good. My old ass S5 outperforms both by a large margin on 2.4 and 5. My home router is high performance Turris Omnia. The pixels sometimes drop wifi completely in the bedroom 20 ft away (with horsehair plaster walls). In the driveway the S5 and Nexus 10 have solid connections and I get nothing from the P3 XL. This issue might be the last straw. WTF Google?

My work it department enacted a rule whereas they want to know every device that is on the network so I have to submit a network address request and give them my Mac address so they can allow my device access to the wifi network again. Maybe your work it ppl are doing the same thing. Maybe work devices are allowed by default.
Also my p2xl wifi reception is weak... I'm about to get a wifi mean network setup so I can get better coverage throughout my house.
My phone seems to be working better the last couple days. I had some problems yesterday, but it ended up just being YouTube Music. Also, my network speeds are great. Even when I was having problems a lot, my link and Internet speeds were up at the top of what my gear offers.
To anyone having, or has had problems, submit feedback on it from your phone. Maybe Google will see it and do something about it. I'm really hoping for a lot of fixes in the November update.
My IT department solved my issue by resetting the system.
Hi,
I have noticed a strange behaviour using Wifi Calling. When I am away from home, and returning, it takes the phone about 15-20 mins for the wifi calling icon to show up and to be available. If I use airplane mode on/off it works instantly. I have seen this a few times on IOS as well, but seems more frequent on Android. So far tested on Samsung S22U and Sony Xperia 1 IV.
Also, today, while I was in a call, using VoWifi, the call dropped and when I looked immediately on the phone, vowifi icon was gone and it came back in a matter of 10 seconds.
Has anyone faced these issues and was able to narrow down the cause of it? My Wifi network does not have a firewall in place nor am I doing any sort of filtering. Changing between DNS servers makes no difference.
Turn off automatic WiFi network login on your phone and check again if it helped.
Hi, I do not have such option available. You mean wifi auto connect when in range?
Yes, because the phone can switch when the signal from the first router is weakening. (1)
Also, by setting up a manual connection, you can be sure that you are connecting to the router you want to connect to, not just any one. (2)

So you're saying turn those 2 settings off? I just recently ran into this issue with my Wi-Fi conking out intermittently and I'm experiencing 20% battery loss over night. I'm thinking its bad hardware. I just turned off these settings. I'll report back if it helps.
