[HELP] Karbonn A1+ Network Data Connection Problem

Hello everyone!
I have rooted karbonn A1+ and it is having too slow data connection problem sometime its speed goes in bytes. I am in need of this forum's intelligent persons to help me.
Actually its data connection was too slow from starting i buyed it and then someone told me root it and then problem will be solved so i did.
But nothing happened. Then i searched over the net and many peoples are saying to simply update modem drivers from service center and it will be solved. and since i have rooted the phone so no service center can help me.
Help me! to update its modem drivers.
Thanks in advance

[help] wifi issue problem!!!

Is there any p8 lite users or just me have problem.. cant connect to wifi even my password is correct
"Denied access to network. Connection Failed"
help me or if there's anyone have same problem let's find solution bout this
thanks in advance :crying::crying::crying::crying:
up for this , thanks in advance for helping me dev's and modders
Same issue....need help
Sadly a common problem. Have read a lot of tips on how to fix, but none have worked for me (clear cache, factory reset...).
Will probably return the phone soon as it doesn't seems like WiFi will ever work properly.
Update:
Talked to Huawei Customer Support (in Sweden) and they suggested a factory reset and trying to connect to a different AP (to verify that there was no problem with the AP). Which I have already done, so next step was to return the phone. So I just did that and they (the store I bought in in) are going to send me a new one, that hopefully works. Fingers crossed.

For me there was a problem straight out of the box. So I tried updating, hoping it would be fixed but the problem persisted.
Saw no difference in before or after update.
thankyou for your response guys ... i'll try to reflash my firmware and back to stock i'll update you guys if i have a same problem after flashing
- done flashing .. same problem still cant connect to wifi !!
someone said that the problem is the wifi chip ,, much better if i go to service center since no solution =.=
