Can Redmi 9C connect to a 5GHz wifi network? - Redmi 9C Questions & Answers

According to gsmarena, and the official website, it should (since it supports 802.11n), but in my case I just don't see them listed to connect to them.
If it's possible, how can I achieve it? I tried changing the region, but still couldn't see the 5GHz networks.

Well, apparently I was looking at the wrong device in both pages, hahahah!
Leaving this here, in case someone else is wondering as well: Redmi 9c (angelica) only supports 2.4 GHz networks. source

The Xiaomi Redmi 9C only supports 2.4G WiFi, which you'll read about on >the website< and probably on the phone's box.

P30 Pro Wi-Fi Hotspot problems

Hi everyone,
I have a problem with my new P30 Pro. When I create a Hotspot in 5ghz frequency, no other device can find that Hotspot. If I change frequency to 2.4ghz then other devices can connect to the network. Maybe others have the same problem? Or my device is faulty ?
BTW when I'm connecting to Wi-Fi, either 2.4 or 5ghz, everything works fine
Maybe it uses a channel, that your other devices do not see. I think different regions use different wifi channel ranges. Maybe you find an option for that somewhere in advanced wifi settings.
I just tried on mine. My laptop pics up the hotspot on the P30 Pro no matter if it's 5 or 2.4GHz, no problem.

I didn't find any advanced settings regarding channel ranges / regions.
BTW my phone is C431 if it's good or not, I don't know. I remember C432 used to be the best region code, if you could say so. My P20 pro is C432.
How the problem started, I bought P30 Pro, opened phone clone app, I wanted to transfer data wirelessly from one phone to another. But devices didn't connect, tried multiple times. After that I started experimenting with 2.4 ghz or 5ghz Hotspot. And found out that other devices can't find 5ghz frequency.

My laptop sees 5ghz Hotspot, but can't connect to it. P20 Pro, honor 8, nexus 6P can't even see that. Samsung S10 can connect to 5ghz. It's very strange
EMUI 9.1.0.153 resolved the issue
Nope, it didn't. I'm still having problems - my notebook can see the hotspot, and can connect to it, but the phone just won't share the internet connection.
Bluetooth is turned on, and bluetooth tethering as well, 2.4 or 5 GHz.
I tried USB tethering. Tried apps from the store. Always the same thing - notebook can see the hotspot, but internet is not working. Any ideas? The notebook is Asus Rog G751. I'm on 9.1.0.1.178.
Same here. Laptop works on home 5ghz, but wont even see p30 pro 5ghz, its strange
Worst part is, 3 months ago it was working. Since I don't use it except when travelling, I have no idea what could have changed in the mean time.
In my case, max user connections was limited.
- press "Show advanced options"
- press "Max connections allowed"
- increase the value

Hi guys,
what network cards are your PC using?
Mine has a Killer Wireless 1535 built in and I can confirm this problem:
P30 (pro) switched to 5 GHz hotspot mode and PC cannot find it.
I think I may have found a reason for it, which needs to be resolved by a manufacturer (Huawei or a network adapter manufacturer - no idea if only Killer is affected):
The Huawei P30 (pro and normal model) seems to default the broadcast channel to channel #149 (5.745 MHz) when switched to 5 GHz hotspot mode.
This is a DFS channel in the only recently approved new upper channel range.
Apparently the killer 1535 cannot or cannot use these channels yet.
Actually it won't see it first. Then, when changing connection mode in the adapter property, it is found.
But after inserting the ssid password, access is not allowed and ssid vanishes from list.
Just like a restriction to invalid channels.
The broadcast on 5 GHz itself works, which I proved with another P30 which can access the AP of the first one.
However my notebooks (all using Killer Wireless cards) as well as a Samsung tablet can't.
So resolution could be:
1. Killer adapts its drivers or
2. Huawei defaults to a 5 GHz broadcast channel in lower, more common, 5 GHz band between ch7 and ch60 e. g.
(Or adds a user-accessible menue allowing selection of broadcast channel.)

Realme x2 pro doesn't detects 5GHz wifi routers

My brand new Realme X2 Pro is not detecting my 5Ghz wifi routers. I tried with another realme model also and that also doesn't detects this 5Ghz Wifi router. I tried searching with various other brands phones like Apple, OnePlus and Redmi which shows up my 5Ghz router without any issues. Seems like it's a software problem. Please look into the issue very seriously as many industrial Wifi Routers work in this 5Ghz band.
You are on custom ROM or on realme UI ? What channel your router set to. Which country you use your phone . When I am on custom ROM I can not see routers that have channel over 64 but on realme UI I can .
No problems here and I'm only connected to my 5ghz band,
On EU model with latest RUI update
i hava same issue with you. And i fix it with this severals way:
1. Turn on air plane mode
2. change your phone region to Singapore
3. restart your phone
4. then try to connect to 5Ghz wifi

Redmi 9C connected to wifi but no Internet

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.

Question WiFi hotspot problem

I have Realme 8, on C09, when using it as WiFi hotspot I can set it only to 2.4GHz. Is it for everybody, or just me?
Redmi note 7,8,9 &10 supports 5ghz as well as some none note variants like the Redmi 9,9T and Redmi 10.
Newer Redmi devices are more likely to have 5ghz wifi support. But when you're in doubt just google the specific phone model and check the “comms" area. If it states that it supports Wi-Fi 802.11 a/b/g/n/ac, dual-band then it supports both 2.4ghz and 5ghz frequency. But your phone does not show support for that wireless band on its specs list.
EDIT: just noticed you said Realme not Redmi lol, this spec here shows that your phone does have support for 5Ghz for sure. There must be a setting that your missing for that. I'm checking right now to see if theres any system settings that allow you to change that. Try resetting network settings.

I know I have 5GHz support, I'm using it to connect to my home network, but I can't set it for phone hotspot.

I have a Realme 9 pro and GT here that I just checked with and I see the same thing here. It only says 2.4Ghz and in the updates, it shows a connections stability update which is probably where they just removed 5Ghz from the AP band choices. I can't understand why they would do that, but with data you really won't get speeds higher than what 2.4Ghz can handle. But going off of what I have here, it looks like most Realme phones have the same thing

Well, I wish I had a special trick to tell you that would allow you to use the 5Ghz band on that phone but I have no idea, sorry man.

Thank you anyway, just the information that it's not the issue with my phone, but with software in general was enough.

If im only connected to Mobile Data i only got 2,4Ghz
*Wlan supported 2,4 And 5ghz i doint know how it is, if the Wlan only supports one of them
