Hi All,
The problem is that the hotspot (2.4 GHz, Device identification:default, security WPA2-Personal) is correctly seen by the laptops but there is no internet connection. I received the Mi 9T last week and it's a great phone except for the hotspot not working properly. I received it with the global version installed, I did all the usual updates up to MIUI V11.0.4 (QFJMIXM).
On the Macbook Pro (Retina 2015, Mojave 14.6) there is a very slow, barely usable, connection which is confirmed by the MCS index = 0, despite the strong signal (RSSI= -26 dBm). Under the WiFi information on the Mac, the country code is missing and the transmission channel is usually an unusaul value (3, 7 or 8 I noticed). For comparison, when using the hotspot function in another Android phone (Honor 8X with stock ROM) with the same SIM card , the MCS index is 7, the country code is correct, the transmission channel is 6 or 11, and the download/upload is around 20 Mbps.
When using a Dell laptop (Windows 10), the laptop connects to the MI 9T hotspot and has an IP but the pages are not even loaded. Funny enough, when both laptops are connected to the wifi created by the MI 9T, they can ping each other correctly.
The data rates on the Mi 9T over 4G are really fast (>40 Mbps). The Honor 8X works perfectly when connected to the MI 9T, with rates > 20Mbps.
Reading other discussions online, someone fixed it with
Code:
adb shell settings put global tether_dun_required 0
I checked the correct value after rebooting (zero as expected) but still no/slow internet on the laptops. Same with adding DUN in the APN type. I also tried to change the SIM from slot 1 to 2, no difference at all.
As a last desperate chance, I unlocked the boootloader and flashed the European version (QFJEUXM) with TWRP. The flash was perfect, but the problem is still there exactly as described above with the Global ROM.
Is anyone else having a similar problem? Do you think that other ROM (Pixel Experience, LineageOS, etc.) may fix this?
I'd really like to keep the phone because the hardware is amazing, but the overall experience is quite a pain with such a limitation on the hotspot function.
Hope someone can finally fix this
