Had this same issue a couple of times, on different ROMs. Ive tried many many ROMs, first time it happened was on a fresh install, when I tried loggin in to the wifi network it was like stuck, never said connected to network, it was looping on authenticating and going back to searching, all kinds of "$#%. Tried re-flashing, nothing... well decided to go on another MIUI based ROM, worked fine. Second time it happened was trying EUI 5.0 everything was soooo fine, until out of the blue after a reboot (3 days using the ROM with no issues), same crap happened with the WIfi. Didnt want to re-flash cause all of the chinesse bloat, decided to try cyanechy 2.1 based on CM12.1 working fine. Anyways, try a different ROM it will work at some point. Weird issue though.

It's a helio x10 bug I think they were supposed to fix it with an update
I've flashed sMIUI 8 but still no WiFi
I'll try cm13 if that change anything...

Edit:I have discovered that the Chinese full of blotware from he was using has caused a nmram wipe as result no one and Mac addresses for Bluetooth and WiFi are available
I've tried flashing the full raw ROM from Xiaomi but stii no Mac and imei
So the point is how to restore it??

ICS ROMS + Wireless Problems

Hi
I have tried many ICS roms and they seem to have wireless problems.
at times it takes time for them to connect or at times they are not able to connect. sometime there is no error message but at times i get authentication error (btw authentication credentials are correct). Is something wrong with ICS. Si anyone else have these problems. Is there any fix for it. i have tried many ics roms with different combination of kernels, mostly its the same issue.
i always have to revert back to GB rom and wireless is fine.connects instantly
any help will be appreciated.
thanks
Hi,
Same here. But I can't decide if it is because of juice defender or ICS. In GB worked ok even with Juice defender.

I've had the same problem. Tried many different ICS roms over the last 2 weeks or so.
The last one I tried - HyDrOG3N-ICS was horrible...
Wireless would not connect at all, even though I was standing right next to the router.
After reading through the forums etc I decided to start from scratch.
I reloaded stock Samsung rom with odin, hard reset the phone, formatted my external sdcard and deleted everything on the int sdcard.
I then loaded latest siyah GB kernel.
After this, I install HyDrOG3N-ICS 23.03
Installed GApps
Rebooted and waited 20 minutes (read it somewhere on the forums)
Rebooted and changed to SiyahKernel v3.0beta6 kernel
And finally installed DXLP7 modem.
I then reloaded all my apps from Market (Not apps restored from backups)
After all this, everything seems to work very well... Wireless is connected and working well.
I do have a problem with mobile data disconnecting every now and then, but it returns after a minute or so - might even be a problem with my provider.
I dont know which one of these steps was actually required - but this sorted it out for me.
It's almost like I had 'leftover' bits and pieces of all the different roms I tried... If it makes sense?
I dont know enough to confirm if this was the case - perhaps its not possible.
Perhaps it was just a happy shot that it all worked for me.
If you have a couple of hours spare - give it a bash...
Cheers

i have read many ppl have some issues with wireless on ICS. i was thinking about doing a factory reset , wipe both my internal and external storage.. but seems like quite a big job getting everything back..oh wellif i am really tempted i will go ahead and do it..but will wait for a while for more ICS build to come out.could be a bug in the official roms itself

[Q] Elegancia 4.8.0

I've searched through the threads but have found no answers, so hopefully someone here can help. I have an Att one x plus. I downloaded the Elegancia 4.8.0 rom several months ago, which is still working great. It was the first rom I installed. My problem is if I try to update to newest version or even try to install different rom all together everything works and installs but wifi wont turn on. In the the settings it just stays wifi turning on and then errors out. Ive turned off fast boot, tried different rom updates and different roms with same result. I do a restore to original Elegancia and all is good.
Sorry if this has been discussed, I couldnt find it and thanks in advance for any help...
you mean to sy that your wifi did work on the old elegancia? 4.8.0? and the latest i suppose 5.7.0 doesnt allow wifi to work?
Thats correct. The original install works fine. Now any rom change or update, wifi will never turn on. Just says turning on.
well i have the same problem was using ViperXL2.0.0 on at&t sim when i switched it to another sim the wifi doesnt work.i am still looking into the solution. Besides this do you still have the link to the place where you downloaded this rom?
flash the boot.img

[Q] 4.3 disrupted wifi, now can't fix

Hi all,
I've been happily following the progression of ROM developments, since I got my P7510 (P4WIFI) and sampling a variety of ROM's up through the versions of Android. I recently upgraded to a 4.3 ROM and developed a problem...I could connect to wifi as always, but could not get internet access (wifi connected, but no browsing, play store, weather apps, etc.).
I worked my way back through a number of recovery backups, knowing that in all of them I didn't have this problem, but it remained.
In desperation, I unrooted and returned to stock and the problem was still there! I found a .pit file for the 7510, re-partitioned, formatted the partitions and reloaded the stock ROM...still no change.
Can anyone point me to a solution? I've googled myself stoopid on this one...
Cheers,
PF.

Try to toggle airplane mode on then off..not sure if it will work on our tabs...but it works on my epic 4g touch..this is just a work around though.
What stock did you return to...
I'll look around and see what I can find...
My first thought was it's a router issue. I've had the same thing happen to me and in the end all that was needed was a router reboot.

Thanks for the suggestion. I tried the airplane mode on/off, but it didn't help.
The stock version I'm on is Build number IMM76D.XWMPF (P7510XWMPF_P7510XSAMP1_HOME.tar.md5)... I believe the correct one for my country...? Not sure if that's a red herring, though. The problem occurred going from 4.2 to 4.3 and has stuck with every restore and rebuild I've tried since.

Thanks B-man.
Tried the router reboot, no dice. Also tried connecting to different WAPs and the problem remains. I tried connecting to my SGS4 as a portable hotspot, which was working fine previously...identical problem...

Z2 rooted and custom rom crashes often

Hello,
at start I have to apologize for my worse english; haven`t written and spoken it for years.
I have an Z2 and rooted it a few weeks ago; after that I installed Cyanogenmod Recovery.
I`ve tried a few Custom Roms but the problem is always the same: It crashes after some time, when I am trying to start an App.
Mostly Ingress and Google Maps. Often they work fine, like 4-6 times, they start without any issues.
But one time it crashes.
It restarts instantly and often tells me I dont have a simcard or it disables the Bluetooth-Connection.
The only possibility is to restart it and after that it works fine... for a few hours till I try to restart an app.
Sometimes it hangs itself up in a boot loop and i have to use Power + Vol Down to get into Cyanogenmod Recovery, but after that the restart takes up to 15 minutes because he calibrates all the apps.
It seems that the problem doesn`t happen when I am using Wlan.
Everything else works fine, no problems, but it is really annoying.
Any ideas?
Please? I have no clue and its really annoying. :crying:

1. cyanogenmod recovery is sh*tty
2. install a pre-rooted stock rom or a modified one like eXistenZ Premium, MoonWalker epidemic or PureX
never had such issues with these roms
Yeah, i know its ****ty, but i cant enter the bootloader anymore; it always starts the recovery. So i cant remove it.
The other problem is, that i tried 4 different roms and the problem seems to appear in every rom.
So it seems to depend on something else.
I'm having the same exact issue except that I don't get into bootloops

The bootloops seems to appear only under Ressurection Remix; i've installed CM again and they didnt happen anymore.
But the problem, that it crashes and after a restart often didnt find my SIM, is still there...
I don't know about RR rom as I haven't tried it but I'm getting the reboots on CM

Le Max 2 wifi problem

Hello,
I just bought a new Le Max 2 from banggood. But I faced some strange problem. I tested with 26S Chinese stock ROM and Lineage 15.1 ROM and I faced same problem. I am starting to think this is a hardware problem to my specific phone.
When I install new ROM, I can use wifi without any problem. But after some usage (it is random and it is about 500-1000 MB of wifi transfer) wifi connection drops the file transfers from wifi. I can't download large files and I can't download apps from google play store.
Do you believe it is a hardware issue or software issue? Should I return it to banggood?
Most certainly the problem was caused by installing the wrong firmware for your device. Check this link to download the correct one: https://sourceforge.net/projects/lineageos-for-x2/files/Firmware Updates/
UPDATE: changing the firmware only temporarily solved our problem. It's back again. Interesting fact: installing any original stock rom (e.g. the 30S) DOES solve the problem. But I want a clean LineageOS or AEX, no stock roms. I tried many combinations, also flashing updated modem firmware over the Lineage build but the problem remains and I can not figure it out.
Maybe @KuranKaname or @CrisBalGreece has any clue?
@coolman7: you are correct, after 500 to 1000 MB's of wifi transfer the connection just breaks.
hello,
what is your wifi problem exactly? Installing 30S stock ROM, fixes your wifi problem permanently?

on all lineage and aex roms I tried there is the problem of interrupted wifi connections. I use the speedtest and nperf tools to check and sometimes it seems as if there is no problem but then after the phone comes out of standby the problems come back. In that case only rebooting helps.
And yes, installing 30S stock rom fixes it permanently (as long as I keep using that rom)... Any clues would be very welcome!
Did you try other stock roms like 26S, 23S, 16S etc? Because I tried all stock ROMs except 30S and none of them solved my problem.

I think the device got delivered with stock 19S rom and I don't recall any problems there but did not do extensive testing with it. I will try 26S and report back what happened.

The wifi speed is not the problem as I reach my full internet speed (280mbps) in lineageos and aex. Problem is that the wifi just quits / breaks after downloading for about 30 seconds (sometimes 5 seconds, sometimes 5 minutes). Seems it get's worse in these roms after the device wakes up from sleep.

I use x-plore app to push gigabytes of music to my phone, and than it works great too.
Really no problems with WiFi.

Which rom are you using, and if not stock, which stock or which firmware did you flash before using your current rom?
@coolman7 I finally figured out what my problem with the wifi was: apparently the custom roms (lineageos and revengeos) use the same, hardcoded MAC address Since we have two of those Le Max 2 devices in our household, they conflicted on the LAN. Manually setting an alternative address fixed it for me (as described here: https://zukfans.eu/community/threads/roms-by-fedor917.1152/page-26) I hope it helps you and otherwise goodluck!
