Lost all old wifi ssids after install of new rom - General Questions and Answers

Hello all,
While going through the initial set up stage of a new rom on my Galaxy S2 I wasn't able to connect to my wifi, the rom simply didn't see any wifi points so I carried on and skipped the Google account bit as I didn't want any settings or apps being downloaded over 3G.
Once the rom was set up I was able to connect to my home wifi and then entered my Google account details. I then downloaded all my apps but my list of previously connected wifi ssids has disappeared. Any other time I have installed a rom, and that is many on quite a few phones, the list of wifi connections is always downloaded from Google along with all my other settings but I assume due to not connecting to wifi at the start of set up I haven't got any of my old wifi connections back. This includes my work wifi which is to say the least a pain to get set up.
Short of reinstalling the rom and hoping I can connect to wifi this time is there a way of downloading my old wifi connection details?

ok. this is quite simple IF you restored the old rom.
enter recovery mode, go in backup and restore, choose restore then restore the rom in which you had all the SSIDs.
now go in play store and download "WiFi Pass Recovery & Backup"(free software). it will tell you all the passwords from the networks you connected to in the past. just write them down on a paper or in notepad, re-flash the desired rom and when you are in the area of any network you can connect using the password you wrote down. i can't think of another method. hit thanks if this helped.
good luck:laugh:

Yeah I had thought of that method but was hoping for something a little simpler! LOL. Thanks anyway, this looks like the only way to do this.

Better alternative!

This works but TrustGo Inc. Antivirus & Mobile Security tells me that it may collect privacy information like IMEI, device model and email account.
Better use this one without security issues: WiFi Key Recovery :good:

Problem solved. I reinstalled the rom but instead of selecting "Reboot" at the end of the install I held the power button in until the phone then went back into recovery. I then installed the latest Dorimanx kernel and rebooted. Dori 9.12 seems to have problems picking up wifi whereas 9.13 has no problems. My home wifi was picked up at the start of the set up and from then on Google reinstalled apps and settings. Or at least is in the process of doing so!
I was a little worried as skipping the wifi set up at the start of my first install meant that there was no email address in the Backup and Restore field within Settings so although the backup and restore boxes were ticked without an email account they may as well have been unticked.. No way to add an email address either.
Thanks for the suggestions, as ever very helpful folks on XDA!

[Q] Rooted P6210 Google market cant connect but it can browse the web fine.

Hey guys, my rooted P6210 seems to have a Google market connection issue. It seems to have happened overnight, it was fine for weeks..and i didn't notice it until i tried to use the market to add a paid app. I get a great wi-fi connection in my home and can browse the internet with no problem but the g-market can't connect and it simply retries. I have deleted the accounts on the device to no avail Any suggestions will help.
Were you able to recreate the accounts successfully?
Try these things:
1. Clear market data
2. re-setup market accounts
3. make sure the date and time on the tab is correct
I discovered mine had reset to the year 2000 after the battery went completely dead. With an incorrect clock, certificate negotiations will fail.

Also, have you tried a different wifi network? Its a long shot but I suppose the port that the market uses could be blocked

Wow, problem solved. I had no idea the date or time had changed because of a charge issue. My brain tells me since the device has an active connection to the internet it would do this all by itself and i never check the tab for those purposes. Now all i need to do is get which exact files to flash using Odin so i can go back to 100% stock. I have searched and found the files but no ((really clear)) directions on which files get flashed. There are 3 all together. Hey you guys made my day..really.

Force Google to forget Wifi networks?

Hello everyone,
My phone (HTC One M7 Verizon) refuses to forget wifi networks. I have a 2.4 network at my apartment that I don't like to use because there is so much interference from other apartments. I have a 5Ghz network that I want my phone to connect to, which it does about half the time. The other half it goes to the 2.4GHz network.
I have tried to go to the wifi settings and forgetting the network, but after toggling wifi it comes back. I believe this is because Google remembers wifi passwords so they can be restored if you reset your device. Is there any way I can remove these stored passwords?
I have also tried editing the wpa_supplicant file and after a wifi toggle the network is restored.
Thanks in advance!
The setting for Google saving your wifi passwords is in "Backup and reset", but this also includes your app data and contacts, so you might not want to toggle it off.
Forgetting the network should work. I've done it on my phones, and it always works, even if I have the backup setting toggled on.
The obvious solution is to simply rename your network.

I did think to rename my network, but would rather avoid that only because I really shouldn't have to rename my network because my phone refuses to forget a network.
I believe this is because of Google because I have recently wiped my phone and installed a new ROM so I doubt any saved network info would have survived that.

It's still a solution though, and a simple one. There's no gain to be had in being stubborn about it.

When you first set up your phone newly installed ROM, it gives you the option to restore data and accounts and passwords. If you allow it, it doesn't matter what device or ROM or whatever it came from, the saved info will be restored. I don't know why toggling wifi un-forgets the network though. That's just weird.

I don't mean to sound stubborn, I just want to avoid reconnecting all my devices that use that network if I can. If that's the only solution that is fine, but I would like to see if I can stop this from happening before doing that.
I don't remember seeing an option but I can not include passwords when I the restore during the install?

I think it's all or nothing.
Rename network.....riiggght. Although correct that will work that's a temporary solution .
I can't keep renaming my home and work networks. If google includes the option to forget a network and it doesn't...that's a bug plain and simple.
Of course its great to have google restore my networks...love it. But if I choose to forget a network....read...feature of the os......it should sync that setting.
Heck...we are not even talking about a restore...if I forget one of my 3 home networks right now....by tomorrow night my phone will have it saved again and I have to forget it again. Need a good ole days option to state what takes precedence....cloud or device or something.

How to delete saved wifi connection?

On my S5, all saved wifi connections were visible in the wifi settings page. On the S7, it seems that only the connections within range are visible. If you go into the data usage / restrict networks, every saved wifi connection is displayed, but there is no way to delete them from there. It seems that there is no way to delete a saved wifi connection once it goes out of range. Anyone know how to do this?

Exactly the same issue here. Anyone got any workarounds (non-root)? Third party apps don't seem to work. Pretty ridiculous that you can't forget a saved network and causes a serious issue for me: I have to change my password at work and can't forget the WiFi AP before getting to the office so I'm locked out of my work account...
It is a bit annoying but I can't see how it's a problem?
How are you locked out of your work account?
You can change password when you are in range.
What's the other issue?

The problematic are Hotel / Airport / etc. Hotspots...
When i received my S7 i "load" an backup from my old android phone... I few days earlier i returned from a long holiday trip and so the "restore-backup" created a lot of hotspots an my S7 i never never need and i'm not able to delete ....
(OK - i can start for a second trip, visit all places and delete hotspot when connected... ) <-- ironic

We use exchange authentication for WiFi at work. The phone automatically tries to connect using the old password as soon as i'm near the office. Does this three times and locks my ability to use the WiFi. This is before i have chance to see it and forget it in the WiFi settings. Such a simple omission in the UX makes this even an more annoying issue.
Yeah OK the work thing sounds a bit troublesome. I would turn off wifi before I go then turn it on when I'm ready and forget the network before it connects.
...
The holiday wifi hotspot thing i don't get still.
Why is that a problem? You can't see the networks anyway. Is it just an ocd thing?
well you have a drastic option, if nothing else works
go settings>backup and reset>reset network settings
this will erase all your wifi, as well as all bluetooth and data connections saved

The problem with the holiday Hotspots is at least not a real problem... But I don't like this.
I would prefer a function to delete Hotspots even when I'm not connected to them...
(maybe it is small security issue, because a common SSID can be used to connect with my phone...)
Wifi Manager - choose Known network, then remove.
I reported this to Samsung support. That's the only way to get them to fix it. The more people report it, the more likely they are to fix it sooner.
As for whether it's a "problem", I suppose it's not immediately a show stopper. However, after only a couple of weeks, I accumulated a lot of hotspots that clutter up the restrict networks page. Who knows, if too many build up it could cause an problem. There is no reason for Samsung to have implemented it in this way. I've never seen a device (mobile or pc) that did this.

Thanks, but Android 6 only allows you to forget those networks that you've connected to using the same app. So you can only forget those that you connected to with WiFi Manager, not the in-built settings.

Edit: you're correct. I think root and find where file or db that stores the SSID would be the next option.
Edit 2: Get a root editor, backup /data/misc/wifi/wpa_supplicant.conf, then edit it to either remove the entire SSID entry, or set autojoin to 0. There may be root apps that does this.
The plain text passwords are also stored in that supplicant file.
I don't think there is any non-root solution until Samsung changes the Wifi settings to show out-of-range SSIDs. I agree that it is silly for it to not do have this feature at all.
2 solutions so far (?)
Hi,
if you have a non rooted S7 there is no build in possibility to delete the saved wifi connections if you are out of range. Samsung has to fix this in my opinion.
With Marshmallow you can only delete wifi networks with the same app you created them, so third party apps like wifi manager do not work. So far there might be two solutions which work, both are far away from being perfect.
- First solution is to delete ALL network connections...and start from the beginning (1. Go to settings -> 2. Bakup and reset -> 3. Reset network settings -> 4. Follow on screen instructions)...including bluetooth etc.
- Second solution is not fine either. Take a third party app like wifi manager from Kostya on play store and list all known networks. Then set up a (fake) wifi access point with the SSID you want to delete. Once they are in range, you can delete the saved wifi connection. You have to repeat this for every SSID you want to delete.
Best regards,
Alexander

can not remove!
I updated my S7 today (with Sprint) to Android 7, and they fixed this. Out-of-range WiFi networks are listed under the "Manage Networks" options and can be removed from there.

Google Pixel WiFi Problem (Fails to download videos, apps, etc. and goes offline)

Hi,
Wondering if anyone has run into the following issue with their Pixel. My phone is an international model (G-2PW4200) and I bought it exactly a month ago.
The issue is this: I seem to never be able to download any decent size file (e.g. a video on social media sites or apps like Facebook, YouTube, Whatsapp, etc., or to download any app on the Google Play store) via WiFi without the download getting "stuck" half way, sometimes not even at 10%. The download would get stuck indefinitely, and only resume once I disable WiFi and start downloading via LTE. Sometimes it also comes back if I just disable WiFi and enable it again. Another problem I have is that my phone seems to go offline when it's not being used for extended periods of time (that being in the 5-10 minute range given I look at it almost every 10 minutes) despite having WiFi during sleep set to be always on. I can tell this because when I try to log in to something like Whatsapp Web it complains that my phone is offline, and this is a problem that never happened with me with my previous phone in the same setting.
A few points to keep in mind:
1- I have "Keep WiFi on during Sleep" set to "Always"
2- This happens everywhere (at home, work, friends', public WiFi, etc.) so it's not related to just my router's setup, and it happens every single day and almost every single time.
4- System is "up to date" and I have the latest update installed (Android 7.1.1, build NOF26V)
3- I'm still able to browse web pages (via Chrome), and browse apps like Facebook, Whatsapp, etc. without getting interruptions or showing any signs of disconnect. It's only the above two issues that I see when downloading big chunks of data, and for some reason my phone appearing to be offline during sleep when it shouldn't be.
Any idea what may be wrong here and how I can fix this? I really would like to keep this phone, but this is really becoming frustrating.
Thanks.
Have you factory reset?

Yes. And ironically enough I ran into the same problem immediately while restoring my backup as the phone was trying to redownload the previously installed apps. It would get stuck not downloading anything but not complain about a lost connection until I disable WiFi and switch to cellular data.
This reminded me that the first time I ran into the problem was also the very first time I used the phone when also downloading my apps.
contact google and get warranty service
can you test your wifi performance with another device?
and also try some download manager like ADM and check download with it.

Given that this happens everywhere, not just with my home WiFi, I know the issue is specific to my Pixel. Unfortunately no one at work has a Pixel to try it, but all other devices connected to the same WiFi spots are fine.
I was told by someone that disabling LTE and sticking to 3G cellular data will fix my WiFi issues. Will be trying that at work today.

Question Family link [TB-J617F]

Hi all,
I've been trying to get family link working as my daughter uses this tablet. When trying to add her account the setup gets stuck in an endless loop never competing. Having read various threads from other devices, I think it's probably something to do with play services not having certain permissions. I would consider unlocking, installing twrp, magisk etc if required to fix, but I don't want to loose widevine.
The long and short is I can't use her account on the device at all as she's part of the family group - her account won't work at all without family link.
I wondered if anyone here had either tried this, or come across other odd behaviours relating to play services?
I'm running the Chinese ROM ziu 13.
Appreciate any thoughts.
Cheers Matt
Few things I have tried (and eventually got it to work) across 2x Lenovo P11 Plus (J616F)'s:
1st one was a factory reset and then instead of using my home WiFi, setup the device using a 4G hotspot from my phone. (Not a clue why, but my Home Wifi (Unifi Access Points) takes upwards of 2 minutes to get internet with the Lenovo's, even though all other devices are fine).
Second method:
factory reset and setup the device as "Offline" (i.e. dont input any WiFi details, button down bottom right saying "Setup as Offline")
Once gone through initial steps, connect to your WiFi, give it 10 minutes to update a few bits.
Open Play Store (DO NOT SIGN IN!), and press the three dots at the top right and goto updates
Let the device update all apps
When complete, try adding the childs Google Account (again, if this fails, try using a 4G hotspot from another device (disabling Wifi on that device first))
Hope that helps
Ok, that sounds pretty strange but I might give it a go. I just set her up a new Google account as nothing I could do could get the old one logged in. Thanks for your advice.
I suspect your unifi is running a shared ssid and your 5ghz is on an inaccessible band, are you always connecting at 2.4ghz? I had to change the 5g band on mine to even see it!

Only have my 5Ghz on normal bands (i.e. non DFS), even tried a separate 2.4Ghz Guest network, disabled WPA3, all to no avail. Not got a clue what caused it, my ISP doesn't block anything either (Zen UK)
Any other device was fine over WiFi (have setup much older Samsung tablets, newer kids phones) all with Family Link, it was just the Lenovo's that was stuck in a loop saying I needed to remove and re-add the account.
Just couldn't figure it out, and had already spent a few hours trying. Hoped the newest firmware would fix, but that didn't help either.
Hope it helps and good luck
Just playing around on the tablet and it appears that it struggles with IPv6 - could be that my hotspot is IPv4 only. Could be related to the loop it gets stuck in?
Not sure why it doesn't like IPv6 though as all other devices are fine with it...
I've just gone through full reset, then tried using 4g hotspot as you suggested. I have to use Lenovo app centre to get play store, then use play store with no login to update. That all works fine. Then add my daughters account. Then I get stuck in the same loop of not being able to register the device with family link.
In my case, I don't think this relates to internet access, I think there's something going wrong with the software / permissions on the device. It's genuinely very frustrating as I imagine it's probably not terribly difficult for the Lenovo Devs to fix.
