mobile data connection (3G) requires reboot

[ryyth96]

I use grameenphone network in Bangladesh and recently bought oneplus 5. i found that my device easily gets connected to wifi. but when i turned off wifi (after using for several hours) and switched to mobile data, the mobile data wan't working. the sim had full signal, i could even call and send sms, and the mobile data APN was also correct. then i reboot the phone and mobile data started working. the next day, i used wifi for several hours, switched off wifi, and then tried to turn on mobile data.....same problem happened. i had to reboot the phone again to get mobile data connection.

why is it happening? any solution. my oxygenos version is 4.5.6

try to update to 4.5.10 first. maybe it solves your problem.
I find the problem strange though

You can do one thing. Turn airplane mode on and then off. Wait for 10 secs.

I have the same issue on my Oneplus 5. Connect to WiFi at home. When I leave, and it disconnects, no mobile data until I reboot. I have tried to turn on airplane mode and off again, does not help. I am on T-Mobile USA. I had the same issue on my Nexus 6P. I fixed it there by changing the APN to turn off IPv6. But with the Oneplus 5 the APN are greyed out. I can't change them. I did add a new APN with T-Mobile's settings, minus IPv6, but that did not work. I am on 4.5.10. The area I am in has strong LTE band 4 and 12 signal.

How would I enable editing of APN's? I do have Magisk root.

Well, I figured this out. I was blocking the kernel with AFWall+. Allow it through and no more issues. Seems to be the issue. May not be the same for everyone.
