WiFi Can't Obtain IP Address on SM-J730F - Android Q&A, Help & Troubleshooting

Hello, After doing root using magisk on my SM-730F I installed adaway, after installing the smartphone it stopped connecting to my home WiFi network giving the message Can't Obtain IP Address, but it connected to other networks without problems. I uninstalled adaway, did a factory reset, cleared the cache using TWPR. The problem is still, the message Can't Obtain IP Address is displayed.
Please help!:crying:
I am a complete layman (I did root for the first time in my life). I would like to ask for an exact explanation of what to do to make the device connect to my home WiFi.

[Q] VS G Tablet with Vegan 5.11 can't get Mac address, FC on device status

Hi all,
Hoping someone can help. I flashed my G Tablet with Vegan 5.11 with Pershoot's kernal. When I navigate to settings>about device>status I get the following FC error:
"The applications Settings (process com.android.settings) has stopped unexpectedly. Please try again."
I have booted into ClockworkMod and have tried the wipe cache partition, wipe data/foctory reset and fix permissions, all with a reboot after each one and none has fixed the issue I am experiencing. Anyone else have this issue. I am just trying to retrieve my MAC address so I can add it to a wifi router for internet access.
I can probably use a work around and connect to another wifi router with MAC address requirement disabled and look at the logs to see the MAC address, but it would be easier for me to fix this.
Anyhow, any help is greatly appreciated. Thanks.

I ended up setting up mobile hotspot on my android phone and retrieved the MAC address of the tablet from there. Would be nice to know if there is a fix for this anyway or if this is a know bug. I don't see it as a bug on the Vegan rom sticky.
I had the same question too and googled this thread.
However, I played around a little more and think I found your solution.
Settings > Wireless & networks Wi-Fi settings
then press the on-Display menu button (the one with the lines that look like an inverted paragraph - I had to google what this button was called too)
Select advanced and it should be there! at least for me it was.
Hope it's what you are looking for!
Thank you for the work around, but it would still be nice to get this fixed. I am hoping the GB Beta 1 being based off of Cyanogen the issue will go away.
i too have run into this issue.
is this a common thing or should i be worried?
Well known issue since day one... the aforementioned process of browsing to advanced wireless settings is the solution for the MAC addy

[Q] WiFi disconnects and connects again after few seconds

So...
I flashed the WKS9 (XEO csc) yesterday and flashed the CF-root on top of it. First I had problems with obtaining an IP adress. IP fixed from android side worked fine but when I press "forget" on the AP and reentered the wifi password it worked without manual IP settings. Then I noticed that Wi-Fi keeps disconnecting and immediately connecting. Of course, before flashing the CF-root I read the instructions and the changelog - it said that the kernel shouldn't break the wifi. But I thought that in my case it broke.
So I reflsahed the WKS9 (one package and without wiping). CWM and Tweaks disappeared but Superuser has been left untouched and I couldn't uninstall it like it was on /system; Link2SD shown that it is on /data (su was removed). After a short messing around with Android Commander and adb Superuser disappeared too (all by itself).
BUT wifi still breaks connection.
One more interesting thing: /data partition shows completely empty!
Edit: It looks like it's losing the IP because if I set IP to manual the phone stays connected. I'm sure that it is not a problem with router because all other devices connected have their IP all the time. Also on router config page it says nothing in "device name" next to ace's mac address.
To fix the wifi
-should I wipe /data or...
-just flash other modem (KB7 for example which has worked with CM7 perfectly)
The same thing happened to me. It's not the root, it's the rom itself. The only fix I found was changing the rom.
Still waiting for a rom with a Wifi that doesn't suck
Have you tried flashing the services.jar within the CF-Root thread?

Help Needed! Suspecious connection attempts to TOR from sh

I have NoRoot Firewall installed. Today it started warning me that there were new connection attempts from the application sh. I looked up the IPs and they are all TOR nodes. NoRoot Firewall blocks the connections automatically but what ever it is still keeps trying to connect. I'm trying to find out what is trying to make these connections. Seeing that the connections are coming from sh I'm hoping something hasn't gotten access to root and is trying to send out personal data. My phone is not rooted. I'm running Android 4.4.4 . It started happening after installing a few updates from the play store so it could of come in then.
Does any one know how I can find out what program is trying to connect to these TOR nodes without having my phone rooted? (and no I do not have any TOR related apps installed)

apps not connecting to internet on wifi but browsers do: help

I am micromax unite2 user and I have recently flashed miui7 ROM. It all went well except that now my apps(system &installed both) won't connect to internet on wifi but my browsers work fine. My phones date/time is set perfectly and I have wiped the cache partition as well in recovery. I have factory reset my phone. I have some doubt about the IP address shown in WiFi settings as it doesn't match with my router's configuration and changing it causes the browser's internet to stop as well. Please help!!

Android 6.0.1 without IP address in Moto G2 xt1069

Good evening!!! 7 months ago, I had to use a backup in my rom aop 5.1.1. In that backup I did for TWRP, I had marked the Persist option without knowing that I was backing up the Wifi. When I used it and the system came back I noticed that I could not activate my wifi networks because there was no Mac address. I was able to solve this problem by copying the "WCNSS_qcom_wlan_factory_nv.bin" file edited with my Bluetooth address inside it and I was able to retrieve the address Mac of the wifi. I spent a lot of time on this system and today I decided to install Mashmallow. That's when I noticed that when entering the wifi password, the system only saves, but it does not connect !!! In the settings> over the phone> status, it is labeled "Not Available."
An important detail is that when I downgrade to KitKat 4.4.4 or Lollipop 5.0.2 stock, the IP address becomes active again and I can use my wifi connections. The problem is only from Marshmallow 6.0.1 onwards. If anyone can help me in this matter I am very grateful. Sorry if any words were wrong because I'm using Google Translate. I'm brazilian.
