If somebody need to use some wifi mesh network (mesh, wifi extenders, multiplus accces points with same ssid, etc.) maybe must not upgrade to oreo. Google for "wifi roaming oreo issues", "wifi mesh oreo issues" and "wifi oreo issues" and you will find many problems like I am having now. My house network has a main wifi router and two wifi access points conected to the main one by ethernet cable. After oreo my moto x4 can´t do wifi roaming like before. Manytimes it is conected but has no internet with an exclamation mark on the wifi icon and sometimes I have no exclamation but the internet can't work. My other devices are working well, roaming well over wifi and the only change was the oreo update in my X4. This bug is not related with de google cast one and is plaguing various devices after oreo update, just google like i said.
The issues are afeting One Plus 3/3T/5, Essential Phone, Xperia Xz... See this links:

At work we installed a new WiFi router a few months back. The connection is open and no one needs a password to connect to it. But many who bought android phones recently arent able to connect to it. I have a OnePlus One with android 4.4.4 which doesnt connect to the WiFi. My colleagues own Xiaomi, Motorola phones which they bought recently, which also doesnt connect to the internet.
The phones detect the WiFi signal, says the network is saved but fails to connect to it no matter what. The temporary solution is to make our laptop into a WiFi router and use it but this is seriously annoying. The router is from HP and I dont know the exam model number for it at the moment
I will be grateful if someone can find any solution for this problem. Also, I am a novice when it comes to gadgets so, if your suggestion is to manually set up my WiFi settings please do so with clear instructions or a video of some sort. However I will be happy if this problem gets solved in a straightforward manner.
Please help!

No need to configure wifi on your device IMO.
Sounds like an issue with the wifi router.
To check an fix the internet settings of the wifi router, you will need the adminstrative access/console/password for the router.
Then you can check that all new devices afre allowed to connect. On some routers you can restrict the access to a list of known devices or by enabling a MAC address filtering.
If you find such options on the HP wifi router, disable it and restart the wifi.
And make sure that the SSID of the wifi network is visible (= not hidden). Some Android devices have issue connecting to hidden networks.
Thread closed. Thank you.
Hello everybody,
I am using an oneplus one running cm-13.0-20160316-SNAPSHOT-ZNH0EAO1QB-bacon and the kernel provided by cyanogen, and I am using xposed. My wifi had been working fine all day but when I went to work and got back I had the following problems: It would connect just fine but there would be an exclamation mark besides the wifi-logo on the statusbar. And inside the wifi-settings there would be text under the wifi I was connected with, stating: Connected, but no internet. This is what I tried up untill now:
-Turning modem/router on and off
-"Rebooting" my TP-link modem using their website
-Switching to cm-nightlies
-Switched to an older lollipop backup
-After that I dirty-flashed the stable cm13 release without installing xposed
I heard some people on the internet saying that there could be a problem with my kernel, but I haven't tried anything with that yet. My worst fear is that it would be a hardware problem related to the fact that I led my phone fall about two months ago. My screen had to be replaced but the sim-tray is still broken. I still need to replace that. Also the grill that is on the top off the top bezel of the phone went off, I think that it's the mic for calls, but I don't know for sure. I am really anxious about this, please help me.
UPDATE;
This seems to be a problem related to my home wifi, because other wifi's work just fine. Too bad that my knowledge in this field is very lacking...
Did you finally find a solution? I have the same problem, only at home and only with my phone (no problem with my computer)...
go into you router settings and change your wireless setting to the following:
wireless channel - 10
wireless mode - 802.11 b/g/n
if the above wireless mode dont work, try the other modes. usually this is set at auto and may confuse wifi on phones
I'm having the exact same problem. WiFi at home works great with PC+Win10, but I can't manage to make it work on the OPO.
It says "connected with no internet" or "connected" but then I can't navigate, and also the device appear as not connected on the router admin page.
WiFi on the OPO works fine at work or other places. I really have no idea why this is happening. I'll try to flash an update.
Hello, before you hate me, my question relates with programming and I do not find anythink similar here.
So I'm develeping android. It has to send data from phone to PC via network (Wifi LAN connection, IPv4, DHCP working). There is NO internet access and never will be!!! On phones like Xiaomi Samsung Huawei and Lenovo it works like charm, but on some phones (Sony, Prestigio)(different android version on that phones, on sony probably 4.0 or 4.4 and 6.0 on prestigio) it is not working, these phones detect wifi connection differently, they connect normally but then they said there is no internet connection and show small exclamation mark next to wifi symbol although they stay connected to wifi and ping agains them works normally, but android api network operation not works anymore, only when I connect that wifi LAN network to internet, android network api started to work normally. So faced someone to similar problem? Is the a solution to make it work on network without internet access? I do not have access to problem phones so I do not can run debugger on them. I will be glad for any advice or usefull link. Sorry for bad english but it is not my native language.
PS: Please it's not problem with wifi access point or network configuration on router or phones, I am sure. Phones from xiaomi, huawei... work normally, same code, same configuration, same network without internet access.

I don't know how you expect anyone to help solve this issue or troubleshoot what is going on if you do not have access to the devices that have the problem. If you do not have the phones in your possession to test them, we can't help you.

Hi. I have upgraded to Pie on my Moto z2 force - and I discover that WIFI is very unstable. Connection comes and goes (and shows up with an X next to the Wifi signal in the top, right corner). No other devices are experiencing this.
My wifi has a high level of security. No all communications are allowed (a bit like captive portal), and I guess that this is causing problems on Pie. Can I make wifi on Pie more simple? Not doing MAC-changing and not checking connection on different connection? I just want Pie to assume that Wifi is on and not try to shift to GPRS.
Regards, Lars.
Hello, I have been having a weird hotspot issue on my S20+ 5G. I do not think this is device specific as it has happened on my S10 5G. It seems to be android 11 related (don't recall it being an issue on android 10)
Little context - I play online games through my hotspot, and randomly it will stop working. Everything says its fine on the phone. However, it says 0 devices connected and I cannot connect unless I toggle off then back on the hotspot. At first I thought it was interference from local wifi networks - but mine is the only one at 149 channel (checked with WiFI Info View).
I only notice this happening when gaming. If I am streaming anything, it is fine. The phone has internet too, so its not the service.
My first thought is some sort of battery saving thing. Like, could there be something in android 11 that causes this cause there isn't enough data throughput?
Im just wondering if anyone has any thoughts to try. I have disabled all known to me battery saver things.
Extra info: Definitely seems related to wifi hotspot only not USB
