[Q] Wireless not keeping passwords - Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot

Ok any help that can be provided would greatly be appreciated. I have this strange problem where the wireless on my phone keeps losing passwords. I can put the password in and the wireless will be fine, but if I leave the phone for 30 minutes or so or disable the wireless the phone loses all wireless passwords and I have to re-enter the password for the access point.
I have already tried the following
Wiping the phone of all data / cache and reinstalling the MF9(crawrj)
Downgrading to MDL(crawrj) and then back to MF9(crawrj)
Also I don'tk now if this has anything to do with it but I can't update my PRL or profile unless I'm on Wireless. Using the 3g/4g I keep getting network errors.
I did search around but the only information I have been able to find is that the people have been reflashing the MF9. While I'm not against doing this, I have already done the steps 2x and it doesn't seem to work. I do appreciate any help though that may assist me with this

I would also like to add that after playing around with the WIFI a bit that I have noticed as long as the screen is on and there is a constant data connection the connection with the access point stays on. However even if I manually add and save the access point, the moment the data connection stops (ie there is no more traffic) the wireless scans an and I lose all access to the AP and it will prompt me again for a password if I try to join. This is a privately owned access point (not a public one based on tokens / time limits).
Again, any help that could be provided would be greatly appreciated.

Wifi looses WEP key

Hi. This happened to me twice on my Dopod 900 so I'm guessing something is wrong here. I have a 128bit WEP enabled home WiFi network. The Dopod works well on this network but I was asked on two occasions to enter the WEP key again. I enter it and it works for a few days and then all of a sudden it is asked of me again... Anyone else seen this behavior? Any ways to avoid it? Thanks
You're not the only one.
The Universal loses my access points (completely disappears from the list) and wants to re-pair my Bluetooth devices (GPS and headset) (sometimes they are listed, sometimes they disappear from the list, too) every so often. I'm surprised no one else has talked about this either.
I've seen it also. If your universal seems unusually slow to connect ot the access point, you better have to stop it, or it will loose your access poitn info. After a soft reset, everything goes back to normal.
This behaviour is appening rarely though, and is not a major bug to me, as it only appens once every 100 connections. It can also depend on your access point.
I connect my o2 Exec with my own and four different customer's ADSL-router/gateway/WiFi devices and have not experienced this, even when a couple of weeks elapse between my site visits. I normally configure full WPA-PSK/TKIP encryption, MAC address restrictions and use DHCP allocated addresses. A VPN is then used to connect from the wireless side through another firewall to the internal network.
Is there any correlation between the WiFi routers that have given you all problems. I use various ZyXEL models.
Getting really strange... All of a sudden, I'm getting prompted for my Exchange password that I connect to 4Smartphone.net... It seemed to have forgotten the password?
WTF?!?
lose wep
same for me
So it is not only my ****ty non -updated sfr rom ;-)
Are you getting a NO GSM message on your boot screen and/or is your IMEI missing from the Device Information applet?
I'm trying to see if the two issues are related.
I got the NO GSM message, and from that point forward, I lost the pairing of my Bluetooth devices and the wireless access points.
My theory: Any passwords or authentications are encrypted using the IMEI of the phone portion. When the IMEI is not present (shows a blank under Device Information) due to the NO GSM issue, the Windows Mobile OS instantly wipes out those "invalid" passwords or authentications or simply invalidates them, causing you to reauthenticate the device to other devices.

I don't know if it is relevant, but in the last 10 days I've come up with the PHONE OFF display without any reason. When this happens the phonepad appears out of nowhere, instead of my carrier's logo, it says Phone Off and the 9000 freezes.
Only soft reset solves the problem No I didn't have any problems YET with the WEP keys in my wifi connections...
Should I be worried though??? :roll:
I'm not getting a NO GSM message on my boot screen or my IMEI is missing not from the Device Information applet. Sorry for not being able to confirm your hunch. The only times this happened to me was when I was at an extreme edge of the WiFi coverage and signal was very low. I was flipping in & out of it and eventually the WEP key prompt popped up. Very strange. Moral of the story for the time being for me, stay near that AP... Oh by the way, its a Netgear for what its worth.
Save and Restore Wifi Settings
My understanding is if there is any problem connecting to Wifi, WM6 deletes the Wifi settings for that access point. I think my friends have come up with a quick solution to this problem. Wifi Hero is a little application you can get for $2 that saves and restores your wifi settings using standard Windows Mobile APIs. Search for "Wifi Hero" and you should find it or the direct link is http://www.wireless-apps.net/desc.php?d=d1&id=246823

Have you guys tried going to start>settings>connections>wifi>power> and putting it at "best performance." I've heard of similar (also experienced) issues when the bar was at best battery.

WING and WiFi

My problems with my WiFi on the Wing (Very FRUSTRATED )!
1. When the screen turns off, the Wifi turns off. Meaning I cant use this as my email machine like a blackberry. I have to turn the screen on to get the wifi back on.
2. The Wifi it keeps "forgetting" the WEP key even though I programmed it. It happens once a week (approx)
3. The wifi keep suggesting that I can connect to all these weird SSID's around me when I have my own router set up in the phone. Just connect to mine and stop asking. At work, At Home, At my friends house, At the cafe down the street. If you dont find these, dont ask. if you do, just connect, stop asking. Stop not connecting.
4. The wifi keeps asking if I want to hook up to LOCKED SSID's. Hey, they are locked, if I knew the wep key I would try to connect manually. Stop asking! Is there a patch that allows the phone to suggest connecting to the OPEN wireless networks after it actually makes sure there is actual internet access in there?
5. How do I tell the phone: NEVER TRIES TO CONNECT TO THE EDGE OR GPRS for data. I DONT HAVE THE SERVICE. The wifi keeps turning off and the phone TRIES to get on T-Mobile GPRS or Edge all the time. I even deleted T-Mobile from my internet connections (I dont have internet access on my t-mobile account as it was extremely slow and I have Wifi everywhere I go, except when I am driving)
After months of use, I still have not been able to use my Wifi. In fact the Wifi does not connect to my router anymore, not even once. I gave up and I am paying for the $5.99 service now.
Sounds like you need to take a look around these forums... All your issues have been posted over the net and how to fix or actually "customize" them are everywhere. You may want to read the manual too since that tells you alot of stuff also.
Reading is Essential!!
The easiest thing to do is start over: reset your router (you might check out your setting on your router as well to make sure your encryption is the same and you haven't been hyjacked.
The messages of secure sites is normal: keep dismissing and it will get it. The ones you normally setup on will automatically log on.
As far as the losing the encryption, thats new: the only way I know to lose it is to reset it, or the phone crashes!!
My suggestion is to READ the manual on WIFI settings. read, try read & try.
it only took me 2 weeks to set everything up, and I never had these many issues.
Have fun. Peace

WTF!!! Crazy data connection!

I have disabled the connection before, but now i can change the password, delete anything and whatnot and the fone will still FORCE connect itself to the data connection, which is gonna cost me big $$. This only happens once I open up opera/pie/google maps though.
right now my connection is basically:
Name:blahhhh
number:#97f399gg
username:sefse
password:hhhhh
domain*:xxxxxdaaa
i have tried everything, even completly deleting all the accounts.
what seems to happen is that the password goes for 5 digits to 16 somehow.
idk if that is back to what it is supposed to be with the #777 connection.
Using 3.0.1 custom DCD Rom, with opera, n some other bs programs
Anyhelp on how to stop this is appreciated

Google Maps and other apps that require data will automatically start a data connection if you initiate them.
If you turn on WiFi this should stop it because you are using another way of connecting.
Do you use your data plan from your carrier? If not you can always go to the EPST settings and disable EVDO and just use 1X. This will kill all data and just let you use the CDMA settings.
Okkkkk
I was able to attempt to activate them before and would just get an error, expectially with PIE, but now idk.
No i do not have the data plan, and im about 2-3MB into data which sucks. Im supposed to have a data block but i guess not.
To kill the EVDO settings, what would that be under?
( making the data parameters section blank did not work)
Also if i do this will i still be able to connect to Rev-A and whatnot?
[obv not do EVDO or able to send mms, but those two i can live without]

You dont neccessaraly kill EVDO all you are doing is only letting your phone see a CDMA signal. Like for making calls and such. This will iliminate EVDO / REV A , but it is simple to go back. Plus i learned that it gave me way better coverage signal, but with no ability to use data.
Completely disable 3g data connections forever, save wifi
This is my first contribution to xda-forums! I'm glad I can help at all when I've benefitted so much... Thanks to all!
NOTE: After the following steps, Modaco's Nodata doesn't even register that a data connection exists! For this reason, if you occasionally use 3g, you probably will want to use Nodata, and NOT the following solution. You just might have to open Nodata and disable the data connection every time you soft-reset.
I was finally able to completely 100% block the 3g data connection on my Verizon XV6800 (aka Mogul aka Titan) was the following three steps:
1. The key culprit is HTC_CM_Guardian.exe in the windows directory. I couldn't edit it or delete it via Total Commander file explorer, but I was able to rename it! This makes the OS unable to find the program when it tries to re-set the Data connection settings.
2. Under Settings > Connections > Connections > Advanced > "Select which networks are automatically used," hit "Select Networks."
3. Under "Programs that automatically connect to the Internet should connect using:" hit "New...".
4. Enter any name you want (mine's "nodata!") and leave all the other settings blank.
5. To be safe, you may have to delete the Verizon Or "Internet" Connection on the Tasks Tab of Settings > Connections > Connections. Save and exit.
Voila! Wifi, yes; 3g, no! No more nasty billing surprises.
Modaco's Nodata program is awesome, but the problem was that HTC_CM_Guardian.exe re-enabled the data connection every time I reset the phone. Plus, HTC_CM_Guardian.exe would also thwart any effort to block data via the "Connection Settings." By renaming HTC_CM_Guardian.exe and creating a "nodata!" connection that programs auto-connecting to the internet would try to use (and fail), we get three results:
1. Modaco's Nodata doesn't even register that a data connection exists! For this reason, if you occasionally use 3g, you probably won't to use this solution.
2. When you reboot, the OS is unable to mess-up your "Connection Settings", so
3. Unless you have an active wifi connection, programs will try to connect to the Internet using the "nodata!" settings, which, being empty, will fail, exactly as planned.
Hope it helps.
Hi,
Can you tell me where to find the guardian.exe file. I cant locate it any where is it hidden perhaps. I need to disable wifi for this phone. The property that I have does not have wifi currently. So the Wifi feature drains the battery. Thank you very very much if you can provide the information.

I just use the slider switch on the side of the phone to enable/disable wifi. I use RyanMogul's ROM and it works like a charm.
I like nueWiFiSwitch - Hardware Switch (it's in Ryan's ROM I'm using) Disable the wifi switch and whenever I want to use it, I turn it on with Communication Manager.
(the hardware switch would turn on random times when putting in or out of my pocket, etc. Works great!

Changing some settings on the 6800 won't stick.

Hey all. I've searched posts and can't find anything but what other people used for a quick backyard fix to get them past. Here's the deal. My phone connects to the Verizon Data Network all the time, even when I'm connected to WiFi. On my Apache, I could go into Settings, Connections, Connections and set the advanced settings so programs needing to connect automatically would use My Work Network instead of Verizon Wireless. However, on my 6800, I change the same setting for the same effect and as soon as I hit ok, it reverts back so it tries connecting to the net via cellular again instead of via WiFi. This isn't the only setting I've found that won't stick, but I can't remember what those ones are. Has anyone found the cause to this and the solution? Possibly a file that's write-protected and shouldn't be or something. I don't have a data plan and can't afford one so I really need this to change and still be able to get MMS when I need to (don't want to disable data completely on Verizon's end). Help!

DNS problems on wifi on rooted S5

DNS issues on a Verizon Galaxy S5, rooted, but intermittently.
What happens is life is good for a day or two, but then I notice that internet access is gone on wifi only. If I turn wifi off and use 4g data, internet access is restored. If I toggle wifi back on, no internet. This has happened on more than one wifi network, leading me to believe it's the phone. Only a "reboot" of the phone helps restore wifi access when it has this problem. Then life is good for another day or two, and then this paragraph repeats.
I've already purchased and installed Override DNS which is a nice app in that it avoids the VPN trick other "set dns" apps use. This didn't help anything, the problem still occurred, and an email to the program's author went unanswered.
I've also set the DNS by changing 20-dns.conf from /etc/dhcpcd/dhcpcd-hooks/ and again, this seems to have no effect on the problem as it still happens.
This page has other ways to set DNS, but rather than try all 8 methods, I figured I'd ask if there's something that's an obvious fix.
Thank you for any help you can suggest. I'm trying to avoid a factory reset.
