5 GHz Wifi Band does not work ? - Lenovo Zuk Z2 Pro Questions & Answers

Dear friends,
Could you please support me. I recently bought Zuk Z2 Pro from Gearbest and when I opened the phone initially it identified 5GHz Wifi band and I able to connect. But after I restarted phone , put my sim card in it , when I open phone second time 5GHz band doesn`t appear in Wifi connections list , only 2.4 GHz wireless points appears. What could be the reason for that ?
Android version is 6.0.1 , ZUI version is 1.9.104.ST
Thanks in advance for your help.

even after updated to last version 2.5.335 , still same problem with Wifi , phone does not see 5GHz bands , any ideas ?

Mi5 lte issue with all roms

Hello Fellow MI5 Users,
I am writing this thread to see if anyone else is having issues like me with my Mi5.
The problem is the intermittent signal issue with LTE, My problem started when I flashed 6.7.28 miui 8 update at first I thought that it was my Network Provider, but when I checked my dad's and sisters phones (same provider) their 4G signal is very stable without any issues at all.
So to describe my problem this is what's happening to my phone.
My phone is now running the latest Global beta miui8 6.8.12
When switching to LTE as prefer connection my phone signal goes crazy from NO SIGNAL - NO SERVICE - EMERGENCY ONLY - NO SIMCARD as I dig in to my settings i change my preferred connection to 3G Only which in my surprise works well and perfect without any issues but the problem here in my country(Philippines) you cannot rely on H or H+ at all since the network provider service sucks bigtime!
So far here's a list of what I did with my phone to fix it
- Flash back to China miui8 later version that I remembered that I don't have any issues with my LTE(Sucks because the issue was there also when I went back)
- Flash to MIUI 7 (Ohh well at this point I thought going back to miui7 will fix this issue but NO, not at all and I'm losing patience)
- Flash all KINDS of CM Based OS (Well switching OS might solve the issue, But believe me it got worst! after flashing all kinds of CM Based OS on my MI5 it all went down to Reboot forever bug (this happens when my phone boots and phone started to connect to LTE)
- Went back to Global beta miui 8 6.8.12 basedband version TH20c1.9-00038 up until now im still using this version.

Could it be you're own carrier hasn't got coveridge for LTE for your device?

In my country lte is Band 3(1800) and mi5 should support that band,right?

For me my carrier do support coverage for MI5, but just recently it went nuts
hi im using official global rom with my mi5 but i cant make native video call on my gsm operotor because of not support miui 7 and 8 so.. is there a rom support native video calling like samsung ?
Mi5 Prime user here. same problem with LTE as well using GLOBE sim, no problem with SMART so far. using China ROM MIUI 8
here are my observations
GLOBE switched to LTE - stable when stationary.. goes NO SIGNAL / EMERGENCY CALLS ONLY when moving in a vehicle
i guess there is a problem on the radio signal switching from H+ to LTE vise versa. unlike my other phone - Meizu M2 Note. no problem switching between 3G / H+ / 4G.

Sucks right? I wanted to switch carrier as well but then again, LTE coverage with smart sucks specially in my location... Hoping that this will be fix soon..
I used to have a perfect LTE with globe 4G+ after some time after updating OS version it went nuts

I updated my mi5 to miui 8 global and got 4g signal but only for a minute or less then it dissapeared and when i manually choose mobile networks i can only select Telenor 2g and 3g...really weird.

Hello James,
I am having the exact same issue on my Globe Sim. I just bought mine last week. Whenever i turn on my mobile data, signal suddenly goes to no service, not detected, etc. Its very frustruating.
Is my unit defective? Or is it just a firmware issue?

I am using both Mi5 and Redmi Note 4x. In both phones, I experience frequent network connection drops for both SIM cards in serted on the phone (one is Sun, the other is Globe). Even while stationary, I exeperience the network drop where the signal bar for both SIMs suddenly simultaneously disappear. The network drop is worse when I am mobile. In addition, the network drop is causing the app I am using at the time to restart. PLEASE HELP.
hi.. is this thread still active? have you found the solution?
i am also from the Philippines, been using globe for 2 years in mi5 with no connection problems, then recently, when i try to connect to data, the signal goes on and off just like yours.. just this month, i updated from miui7 to miui9 and the problem got worst! when i connect to mobile data, phone reboots after a minute! i tried every fix i found in the internet (reset APN settings, factory reset, airplane mode) but nothing seems working.. So i tried Sun as my other network and it works perfectly fine.. Also, i tried to interchange sim 1 and 2 slot but still not fixed.. Another thing, when i turn the data in different place, my connection seems okay.. i live in cebu city but works in lapulapu.. the problem occurs in lapulapu..
help! is this network related or somethings wrong with the phone?
Good to see this thread. I thought my phone had a factory defect.
based on my experience.
version 9.1.1.0 and below only loses signal for globe while on data connection in some locations .
higher versions up to the latest(now is 9.5.5.0) causes our phone to totally reboot in some locations as well.
maybe it has to do with the signal/radio frequency on the area for the identified carrier(Globe).
this is easy.
root then disable LTE band 41

How do you disable band 41?
Thank you in advance.
easy way > install network signal guru > 3 dots (menu) > lock bands > lte > uncheck b41 tdd 2500.

Network problem with Redmi 4x

Hi . I bought a redmi 4x a few months ago .
Initially, the version of this Phone was miui8.2 and I upgraded it to miui9.1 and android 7.1.2 .
After a few months, when I'm connected to the Internet through the SIM card, after a few minutes, the connectivity sign to the network is visible , but has no internet .
I suspect that this problem is due to the upgrade. For this reason, I downgraded the phone version to miui8.5 but I still have this problem
Even when I put the network mode on 3G, I still have the same problem
I tested this SIM card with a different phone (samsung j5 2017) and had no problems
Please answer my problem
What should I do ?
Check APN

Question Mi11 since 4 Weeks - My Problems

Hi ,
Since 4 Weeks im the owner of an Mi11 .
Unfortunately I have to say that I am very disappointed with this Device .
My Problems are :
- very poor WLAN Receive Power ( maybe the Antenna ) , i change my AVM Fritzbox against an new one , but still the same Problems . Mesh Thettering / Switching dont work perfectely . With my Company Phone , an Iphone 11 the Mesh Roaming works like charm and it receives in my kitchen 560 MB/s with the 5GHz WLAN.
My Mi11 drops down in Kitchen, wich is 3 meters away from the Fritzbox to 10MB/s or it loose the Connection completely . The Mesh roaming dont work too.
Till the Mi11 change to my Repeater the Bandwith goes down to 5 MB/s the maybe it switches to the Repeater who can deliver again 500 MB/s .
- Poor Mobile Network Power . I loose the Connection on Calls on Places where i can take Calls with my old Huawei Phone.
Am I the only one with these problems or do others feel the same way?
Thanks
Michael
I don't have such WiFi issues
and regarding mobile data, are you using the same operator and SIM card as in huawei?
Ok , Hmm . I use the same SIM as under the Huawei Handy .
for wifi -> i have the same, disabling WPA3 helped a little on my fritzbox but not in total
mobile --> the same, i have my company pixel 5 next to my mi 11, both have deutsche telekom sim, pixel is having a much better signal and also gets higher download speeds
Clear system cache, network reset, clear sim card tool kit data, check Access Point Names, replace sim card.
Also, try to adjust the incoming signal throught the hidden menu of which your sim approves.
I dont have these problems with my mi 11.
I have my Mi11, since the beginning of last month, and i must say i never experienced bad wifi/cellular connection. So i suggest you make a network/factory reset..

I think Xiaomi's European models have problems in all areas that the Chinese models don't. My CN model has fantastic WiFi values with both the original and the Xiaomi.exiaomi.eu ROM. I also have the Fritzbox as a router.
