redmi Y2 connects to wifi but internet isn't working - Xiaomi Redmi S2 Questions & Answers

my router is tp link archer c50. the wifi internet is working for other devices but not for this redmi y2. it worked briefly but when i restarted my router and pc, the internet to my redmi y2 stopped working (although it worked for other devices). found a similar previous question here https://forum.xda-developers.com/redmi-note-4/help/wifi-connected-internet-please-help-t3611053 , but unlike that user i'm not on custom rom. it's miui as sold by the manufacturer.
Appreciate your help.

you might want to just reset your network settings on your device, since you have confirmed that the router supplies internet to other device but not to S2. go to settings>MORE>reset network settings

[Completed] [Q] wifi problem with zopo zp999

Hi everybody
I bought a Zopo ZP999 2 weeks ago and globally i'm very satisfied with it. The only problem is that when I connect it with my wifi network after 15 seconds i'm still connected but without debt. My smartphone run under Android 4.4.2 and I'm connected with the protocole WPA AES.
I just want to say that at my work every works perfectly on the wifi network. I tried to change the security protocol at home and nothing change. I also tried another router wifi with 3 differents protocols and same results.
Is somebody have a solution for this problem ?
Thanks a lot
Jeff
So if you're saying you have no issues with wifi at work but at home, you need to contact your home isp and trouble shoot with them.
Thank you

Different brand phones have different behaviour on network without internet access

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.

Redmi 9C connected to wifi but no Internet

I just bought this phone and I'm trying to use it in my network. I use Ubiquiti products (16-port switches and a bunch of AP access points). I connected the phone via wifi to my network and it has no problem for a while until it just doesn't have Internet connection. It stays connected with its IP address intact but for some reason it cannot seem to reach the Internet. The workaround is to simply turn off the wifi module and turn it back on. It's randomly happening and the workaround is very annoying.
I have a couple of other mobile devices (iPads, iPhones, Android phones, Windows laptops, etc.) and I never experienced the issue with these. I tried connecting the Redmi 9C to all my wifi networks:
Guest wifi with captive portal
Main wifi with RADIUS authentication
IoT wifi with regular WPA2 personal authentication
I tried resetting the wifi settings of the phone. I tried reinstalling the latest MIUI fw/sw.
and the result is the same, every time. At this point, I can safely consider that there has to be something wrong with the phone. I'm not sure if it's because of the MIUI 12 update because I updated the phone to the latest firmware as soon as I got it out of the box. Is this a known issue with this phone? I have another Xiaomi phone (Mi Mix 3) on the same network without any issues.
Any ideas?

Mikrotik does not recognise OnePlus8 as LTE device (USB tethering)

Hi,,
I would like to use my OnePlus 8 in USB tethered mode as an LTE device for my Mikrotik hAP ac lite router.
When I connect the two, OnePlus indicates that it is charging and even though I adjust that to USB tethering the Mikrotik never detects the modem.
I tried the same setup only replacing the phone with a Samsung S8 and the connection worked as expected.
Has anyone else experienced the same behaviour and has anyone else manage to find a solution?
Thanks
try using a router that uses recent version of OpenWRT and it should work, i got it to work on my openwrt router but not on my asus router. however my asus router worked fine with my older phone. Asus router needs firmware devs to fix the issue
In fact when I upgraded the Router OS firmware to Beta 7 it worked.
