Redmi 9C connected to wifi but no Internet - Redmi 9 / Poco M2 Questions & Answers

Sorry for posting in this thread, but I cannot find a Redmi 9C section. 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?

Mods, I found the Redmi 9C section and I posted there. You can delete this thread. Thanks.

Not working: 802.1X / WPA2 / PEAP TTLS MSCHAPV2

Hi,
I'm trying to connect to a WiFi network that is protected with WPA2 with PEAP / TTLS.
It simply is not working. No problems connecting with my HTC Desire though.
Anybody experiencing the same bug? I already installed the required root certificates, tried various combinations of user account / password. The thing is, that the network is provided by my university (Eduroam if you are familiar with that) and it is very annoying that I have to fall back to HSDPA consuming my data quota.
Cheers,
chross
Normally with eduroam wifi there isn't wpa2 or other key. Just connect your phone to it, open your browser and you will be redirect to the website of your university and then you can log with your id.

Yes!! This is the exact same problem I'm having with my university wifi

I'd configure the settings on my uni wifi choosing PEAP and then MSCHAPV2 and put in my log in username and password according to the instruction and as soon as press connect or save it looses the signal immediately to very low and never connects. We also have eduroam as an alternative they tried that and same problem just doesn't want to connect.
It works perfect on my htc one x. I'm beginning to believe the phone has a bug.
It does have a bug. It doesn't connect to 802.11 n!
My problem was solved by reconfiguring my AVW Fritz!Box 7270 to 802.11 b+g only and limit the phones wifi frequency to 2,4ghz only. You can find that in advanced wifi configuration.
I'm lucky i only recognized this bug in my own wifi network and not others i don't have admin rights for...
eduroam works for me with PEAP/TTLS but I guess it's 802.11g
I'm on the 40002 rom, but worked also on the 31006
After receiving the 4.0.4 update yesterday, WiFi now works flawlessly.

Hi there,
I got the same problem with my university network in hamburg. I updated the razor to android 4.0.4 (Stock-Rom: 81.5.40002.XT890.Retail.en.EU), also the phone is rooted but still not working. Our IT advices to use WPA2 Enterprise TTLS/PAP authenthication in combination with a t-com root certificate. Every time i safe these setting the wifi signal drops as told by previous posters and the connection fails. When i enter the settingspage again, all settings are reverted to default. This also happens, while trying to connect to eduroam
any further advices?
Thanks in advance!
I have no problems connecting to eduroam at Braunschweig and other citys. Maybe you can visit the IT Desk at your university?

Yep, me and and a fellow student went there and told them about the problem. But they also gave up, after trying about an hour or so. It seems to be a general problem in the used android build, at least there are a lot of post reporting this at the google code repo -> code.google. com /p/android/issues/detail?id=15631 (sorry for that but I'm to new here to post links). I'll try the provided tips like changing the wpa_suplicant file tomorrow and report the results. Seems to be strange issue, if it works for you (and probably others), because a fellow student got the same Phone and has the same issues
Thought I'd just give an update as I have the same issue
Motorola knows about it, it's been reported to them before and said it'll be fixed with the next update.
Working smooth here with WPA2-Enterprise, PEAP and MSCHAPv2. Using it every day.
But I'm not using TTLS, you might want to disable that if you don't have a valid certificate for your mobile/user.
Also important, fill out the "anonymous user" field with your username. Depending on the RADIUS configuration of your IT this might be required.
[edit]
Just checked my mobile. I don't use a Phase 2 authentication, only EAP = PEAP, no certificates.
Got it working!
After 2 hours of searching the web and playing around, I got it working now, following this guide posted on google code repo:
Razr I (XT890), retail eu, running android 4.0.4 (stock), no root
after endless hours of trying i was able to connect to my university network a couple of minutes ago with the combination of two apps.
1. WiFi Connection Manager
Enter SSID manually
Security "802.1x EAP"
EAP Method "PEAP"
Phase 2 authentication "MSCHAPV2"
Identity "your identity"
Anonymous identity "your identity"
password "your password".
2. WiFi Advanced Configuration Editor
Check Hidden SSID
Key Management: unselect IEEE8021X, select WPA_EAP
AUTH Protocols: select LEAP
Enterprise configuration: make sure Identity and Anonymous Identity are set to your identity, Enter your password
check whether the settings are saved in WIFI Advanced Configuration Editor. If not switch of stock WiFi and repeat step 2 (!!!). Now it should work.
Turn WiFi on and connect to network (Stock WiFi; don't care about settings there, phase 2 authentification is still not saved)
After switching the device off and back on it did still work. Same when leaving and returning to WiFi area.
hopefully it will keep on working. i just tested the browser and play store. didn't discover any problems so far.

Connection is stable, but there seem to be some problems regarding to the speed. Whatever it's usable for stuff you do regularly @university.
Hope that helps others, thanks to klemens

Thank you for sharing, this made me so happy!
It's those two apps which made my connection possible.
My eduroam configuration is quite different, but the apps did the trick. I fiddled with advanced wifi config editor alone for hours without any result.
Now I just hammered the config into those two apps and what can I say - proxydroid reported a connection a few seconds later.
I dont't know what Moto's Problem with 802.1X is.
Defy latest stock rom - no connection. With CM -> no problem.
Milestone 2 with stock rom - no connection. With CM -> no Problem.
Rarz I no connection with stock wifi manager . . .
My fellow students with their samsung devices seem so have no problem at all. ^^
(even Win Mobile 6 works, thats a little bit depressing)
btw, speed is fine here. 16Mbit up&down is more than I need on a phone.
Greetings from Kiel.

OnePlus 3T WiFi Problem on Open Beta 8

I own an OnePlus 3T running Open Beta 8, and I've come across a rather strange problem with the Wi-Fi.
It is basically a problem with this one network. It has worked fine with all others I've had it on. It'll connect to the router but will have no Internet access, a Wi-Fi fixer tool I used reports Internet as disconnected and it also fails the DNS ping tests. When you connect after a while there'll be Internet access for a minute or so but then it disconnects again. What's interesting about this problem is, that other devices on this network lose their Internet connectivity as well. Upon disconnecting the phone, they regain Internet access.
I've tried all the standard fixes, resetting the router, resetting the phone -- which solves the problem for about a day or so but it comes back around. I've changed the IP to static and back. Assigned DNS manually. Even attempted creating a hotspot with another device connected to the network. And tried the WiFi Doctor app, but nothing has worked so far. This problem was also persistent in Open Beta 7

No/Slow internet on wifi connection (Android 7, OxygenOS)

Hi together, i got my first onePlus this week.
basicly i really love it, but since the first day i am in struggle with wifi/internet issues.
I read already some Threads on this and other sites but i wans't able to Fixed the issue.
Now i didn't know how to solve the issue and hope one of your guys can help me to solve/localize the Problem...
At first i always lose the Connection, which could be solved by switching of the intelligent wifi (now i know, the wifi dropped because of the missing/slow inet Connection).
1. Problem Description:
the Oneplus is connected to wifi, but when i try to visit a Website or Open the AppStore the Internet Connection is verry slow, or not correct etablished. Sometimes, often after a Router restart or deleting the Oneplus from routers known device list, the Internet Connection via WiFi Works fo 1-15min.
2. Network Architektur.
OnePlus is connected to the Router (Fritz!box). The Fritzbox Works in client mode and gets the Internet Connection from lan 1 Port, which is feeed from a Radio Network (because we have a slow Connection i get Internet from a local Provider). the Fritzbox used 5ghz and 2.4ghz. the Last one is repeated by WLAN repeated(from avm too).
3. one plus os Updates:
- got Oneplus with Android 6!? but the Problem was present. (didn't Check oos Version because i thought an Update could fix the Problem)
- Update to oxygen os 4.1.6 (Android 7)
- Factory Reset because of the Problem
- flashed to Open Beta 10
4. what i have tried
-other devices
- on a Network from Family (with an other Router (from Telecom) and Simple Network complexity -> worked perfect
- remove repeated
- use only 2,4ghz and 5ghz
- changed WLAN channel (i have some 2.4ghz networks around me but nothing 5ghz, so this shouldnt be the Problem source).
- restart Oneplus and Router (which sometimes Works for some Minuten)
- configured Static ip on Oneplus (not possible in Router because client mode)
- Factory Reset
- perform wipe Cache
- flashed to newest Beta
5. What i want to try but where i was faced with other Problems:
- use ipv6 on Router,. not directly in client mode.
- root Oneplus to deactivate ip v6, not able to root, because OEM unlock doesnt Works (after entering Pin nothing happend, OEM is still locked).
i Hope somebody can help me or give me some Input.
best regards

VPN connecting issues

Well ... it seems that i have some issues connecting to a VPN server (manual connection, from Network Connections -> More Network Connections -> VPN).
I cannot connect to it from Note 8, while i can succesfully connect from Note 4 (same networks, same router, same configurations).
On Note 8 i am on N950FXXU1AQI1 fw.
I had even Factory reset it and tried again, but without success.
I am adding server log for both note 8 (red) and note 4 (green).
Can someone try to see if it works (manual VPN, PPTP type)?
-------------------
Later update: tried AnyConnect as well (to a eneterprise VPN that i use) and it DOES NOT work as well (connection failed), while on Note 4 it works without a hickup.
So it seems, that at least for me, i cannot connect to ANY VPN network, which is an major issue for me.
I've had issues with my note 8 vpn as well. I usually have VyprVpn and PureVPN. The connection is a hit or miss really. And when it does connect, it starts with no connection and then network speeds up but slowly.
Hope this helps.
i understand, but i am forced to use that VPN app as i a company constraint (AnyConnect is CISCO VPN - weidly spread in companies).
While the Android Default VPN should work out of the box ...
VPN
I use pulse secure to vpn to the company intranet.
well ... factory reseted one more time, and all is working ... really strange ..
Turn off power saving
I know this is an old thread, but I just ran across this issue myself and found that if I turn off power saving the VPN works well. I hope you had already found this or another solution.

[I3113] WiFi issues

Hello together,
I have a weird issue with my Xperia 10 (I3113 with unlocked Bootloader on 53.1.A.2.2).
At work we use Cisco ISE Sponsor Portal to provide WiFi guest access. I login using my credentials and everything works fine.
After a while I have to re-authenticate - this happens multiple times per day.
I noticed a similar issue with my WiFi at home. The phone is connected to the WiFi but has no internet access (same phenomenon as at work).
Has somebody experience a similar issue? Is this maybe related to the unlocked bootloader?
Greetings
I had wifi issues before i4193. It disconnects then reconnect itself automatically. I read some thread for xperia phones sine im unable to find any discussion specific for xperia 10. Luckily i found something saying that it underestimate the signals for dual band routers with 2.4 and 5ghz. My router at home is dual band but sharing the same ssid. I have it separated and now problem no longer exist. I can connect either to 2.4 or 5ghz signal without being disconnected. Hope this help.
Thanks for your reply.
I'm gonna try 2.4 GHz only and give feedback
