Mobile network connection constantly fails on low signal

When I have one bar of signal its pretty much impossible to do anything online and with a 2 bar signal it can be hit or miss, browse the web, update apps, use a tether etc, the connection to the server just fails.
Using my old LG GT540 I could do anything online with a low signal although it was a little slow, I was wondering if anyone else had seen this, and if they have is the cause known, it could be my network I'm just trying to work out if its the phone.
It can show a HSDPA signal but data just doesn't get transmitted, I have also seen the HSDPA signal completely drop out before now with a 1 bar signal. Also has anyone seen it before the LFB update, but haven't after the update?

[Q] Alcatel One Touch Evo 7

Hello,
I'm new to this forum. I have Alcatel One Touch Evo 7 tablet and after updating the software to newer version, it started having problems with the 3g modem - it can detect a network but it won't connect with any. Surrpisingly - whenever I connect with WIFI, the 3G or EDGE icon appears as well and it looks like I was connected to both WiFi and mobile network! I double checked the APN settings and it was working before - now it isn't... Is there some way to downgrade the software or flash it? I don't have a warranty for this tablet.
When you have active wireless connection, the "modem icon" only show signal strength, it's true that E or H depend on "what it hear" but that's all. So if modem get signal from umts it will show umts (even when he is unable to connect because of poor quality), because he thinks that he is connected to the GSM, but he is connected to net threw wireless. (like it have only one connection status for wireless and gsm)
And as for me, my evo7 behave the same way as yours when i have something wrong with APN, so my guess it that you have:
-apn or other settings problem
-signal strength - check your signal and other in settings
-hardware problem - maybe some interference with other components, like gps, wifi, ... (i have evo7 that have good gps but very poor gsm, and my friend bought evo7 that have GSM like a rock, hardly ever lose gsm network, but gps work like hell, sometimes never get fix or lose it all the time)
My question: How did you do software update? I somehow didn't find any room or how to do that.

Connection problem on H/H+

Hi,
I have a problem with my internet connection.
When I am on LTE/4G, there is no problem but if I am on H/H+, I don't have any connection. It is not just slow, I don't have anything.
I leave in France and my operator is Sosh on Orange network.
My Mi 10 run on xiaomi.eu weekly.
I tried on xiaomi.eu stable.
I used miflash to reset my phone with official 12.0.6 and connection worked on H/H+ but if I update to last official 12.2.7, it stop working.
I tried resetting Apn and I doesn't work.
I don't want to stay on 12.0.6, I like miui 12.5.
Anyone have an idea?
Thanks
Try setting the network preference to 3G only. If your phone is network dependent it could be a setting on the network side telling your phone that 3G isn't available. If the firmware you're trying to install isn't for your phone then it won't know which bandwidth the signal is on or it simply might not support it..
Hello !
Same for me, 4G/4G+ no problem but when it's H/H+ no connection i'm on Orange too.
I'm on Miui 12.2.8 and no problem before install the update there is 3 weeks.
No idea..
Same here, no issue with the 4G connection but nothing in 3G, this is really a pain in the ass when in rural location.
Orange provider too.
