Set DNS1 & DNS2 in WiFi settings rather than in Build.prop

[Q] NJ4 WiFi Issues

I manually upgraded my i337 from NB1 (4.4.2) to NJ4 (4.4.4), and then I re-rooted it. While I noted minor differences between the versions (I now had the "Custom Unlocked" logo on the splash screen, for example, and the notification "shade" did not scroll off and on as quickly), the most problematic issue was WiFi connectivity, which caused me to reinstall NB1 (pending a solution).
With NB1, my WiFi worked as I thought it should. It would automatically re-connect to hot spots and, if there is a password, it would automatically handle it for those sites I had logged into previously. Thus, for example, my phone would automatically log into my home WiFi router as soon as I walked through the door.
It appears that NJ4 is broken. I have found that under NJ4, the WiFi will only *automatically* re-connect to the most recently-used hotspot (whether or not passworded). This is not affected by restarting either the phone or the router. Thus, if I connect to my home router, the phone will re-connect effortlessly PROVIDED I don't connect to any other hotspot. If I have connected to another hotspot, once I return home, I find that there is no longer an automatic connection (I receive a "WiFi Hotspots are Available" notification), and once I initiate the connection manually, I am asked for my password EVERY TIME. At least I know my home password; I don't know the passwords of the many other hotspots I have connected to.
The collected WiFi credentials are maintained in the file data/misc/wifi/wpa_supplicant.conf. I looked at that file to see whether the passwords had been deleted. No, they were all still there (albeit encrypted). Here is an entry like the one for my home router:
network={
ssid="SqueekyNet"
psk=[the encrypted p/w is located here]
key_mgmt=WPA-PSK
priority=657
frequency=2462
disabled=1
autojoin=1
usable_internet=0
skip_internet_check=0
}
Note the line that says "disabled". The system inserts this line once you log into a *different* hotspot. It does this for *every* entry, so the only entry without this line will be the one for the current hotspot (or for the most recent one, if you aren't logged in to any WiFi hotspot).
I have found that if I edit the wpa_supplicant.conf file on-the-fly ... changing "disabled=1" to "disabled=0", then my home WiFi is instantly recognized, and I am immediately logged in (the "forgotten" password isn't really forgotten). Further, if I then re-examine the wpa_supplicant.conf file, I will see that the "disabled" line has been deleted from the current hotspot, and will only be re-inserted once I log into a *different* hotspot. BTW, while I am using the home hotspot as a test, the same behavior applies to ANY hotspot. Thus, under 4.4.4, NO hotspot is logged into automatically (unless it is the most recent hotspot), and unless you are attempting to log into the most recent hotspot, you ALWAYS receive a request to enter the password for a protected hotspot (even though the password is actually still in the file). I use WiFi heavily, and this isn't viable for me.
The problem apparently isn't limited to the i337 (AT&T) build of NJ4. I noticed this discussion in the T-Mobile forum: https://support.t-mobile.com/thread/84926 (I tried to comment on it, but I can't register for the forum since I'm not a T-Mobile customer).
I am now comfortably back on NB1.
Does anyone have a solution for this?

UPDATE: I found that after I reinstalled 4.4.2 (NB1), using ODIN and then Titanium Backup, as soon as I activated WiFi, my device would strip all of the entries from wpa_supplicant.conf that contained a password (psk). I tried a number of different techniques to reload my original wpa_supplicant.conf file, and was never successful. All of the entries without a psk remained, however (there are hundreds).
I also found that after reinstalling NB1 (including the restore via Titanium Backup) once I re-entered the password for a particular WiFi hotspot, then the re-entered password would stay in the wpa_supplicant.conf file (and the phone would again login to WiFi automatically, without ever/always asking for a password re-prompt as was happening with 4.4.4 NJ4).
While I don't really know for sure, it is my guess that the psk entries were stripped from the wpa_supplicant.conf file by the Google server. Not sure why, but since I am able to totally restore the device with all of the pre-backup data files (including the original wpa_supplicant.conf file), this is my only explanation.
For me, NB1 works to remember passwords and log-in automatically to WiFi hotspots; 4.4.4 NJ4 does not.

[Q] VERY Strange WIFI Issue

OK i seem to have this extremely bizzare wifi issue.
I can connect to wifi access points fine, if i turn off wifi and turn it back on i am unable to auto connect and have to re-enter credentials for it to connect. Before doing so i checked my wifi ap to see if my ap were listed and they were not.
If i re-enter everything is fine but having to do this to wifi ap is annoying. After i have entered and check the wifi ap files i can see the credentials are saved etc.
If i do not re-enter the credentials and restart the phone with wifi enabled it connects to AP fine.
If i leave wifi connected and connect to to wifi aps that require certs its fine also without the need to re-enter creds.
At first i thought maybe i had a corruption in the wifi config files but i dont see any, no duplicate aps at all, no fancy characters i can see.
Does anyone have any thoughts as my wifi config with aps is many years old and has a massive amount of APs listed.
It doesnt matter what ROM i try as soon as i restore all my APs the issues start, is there a way to bulk export, wipe wifi aps and re-import them all again?
Do wifi aps with spaces in or length cause issues with 5.1.1?

1 root ur phone if you are unrooted 2 download any build prop editor from playstore 3 change this line ro.securestorage.support=true to false in /system/build.prop 4 if it doesnt work try a different build prop editor cz the changes might not be sticking 5) hit the thanks button if it helped

Cannot Access WLAN via a DHCP connection , only by using a Static IP

Hey everyone, long time reader- first time poster- hopefully someone can help me!
really frustrating issue, after over 2 years of near flawless use with my n9005 yesterday i noticed i was no longer connected to my saved home wlan, every time i tried i would receive the message: AP currently not in use......, i proceeded to restart phone/router, forget network- and re enter details without any success. after googling the issue i tried all the basic suggested fixes, toggling various wifi settings, toggling date and time, toggling wifi power saving mode via *#0011# all without avail. I researched further and attempted to access the dhcp_list to delete it via root explorer (also viewed the permissions using x-plore and its all ticked for read and write accordingly) etc, however i was never able to do this- always being told i didn't have the file permissions, same story when trying to use terminal with the input: rm /data/misc/dhcp/*. I have checked and do have root access and always granted access before attempting these through the configs of the file explorer and super user or by typing su first in the terminal. Whenever i enter a static IP it connects and works immediately, however when i was out the house yesterday i noticed it was doing the same issue with 2 other saved WLAN networks which being public i cannot use a static ip/ and ultimately cannot join/use. So last night i factory reset my phone/cleared cache this did not work as im still receiving the same Obtaining IP Address loop and AP not in use error message and once again the Static IP work round is my only way to gain access. Im now at a loss what to do next, considering to flash a different ROM/Modem/Boot Loader but dont know if this would be any help?. My system details are listed below any help would be much appreciated
BOOTLOADER: N9005XXUGBOA5
RADIO: N9005XXUGBOA1
home wifi router is the, EE brightbox

Solved installed new ROM all good!

Password for already saved WiFi networks are shown encrypted in Wps Wpa Tester app!

Hi all
I have the 935F Model, and it's rooted. Have any of you tried an app called "WPS WPA Tester" on it?, I used to use it on my old Grand 2 and it worked well, but now when I hack a WiFi with it the Password of that WiFi is encrypted and some times it deosn't show at all.
So what is your experience in this domain?
PS: there are two solutions on the web for this (adding a line to build.prop Or deleting a file in the system folder) and both didn't work.
