[Q] Forgets wifi password after router reboot [Nexus 5] - Android Q&A, Help & Troubleshooting

Hi all. At home I turn off my wifi when I go to work and when I turn it back on, my nexus 5 doesn't remember the password. My nexus S was the same. This recommends switching my router to WEP (it's currently WPA-PSK), however I'm not sure I actually CAN change this in my router settings. Shouldn't it just work anyway, or is it a router problem? Should I just stop turning off the router? This feels like it shouldn't be a problem: why can't the phone simply paste the password into the box for this specific router name & ID, rather than me typing it?
Thanks for any thoughts!

Never had this issue and WiFi password should be stored in phone so I'm not seeing how its a router issue. But at the same time how often are you rebooting your router? I mean once a year is a lot to reboot a router

Seems odd that it would be a router issue but that's what those guys reckon.
I turn it off when I go to work or away for the weekend. Was quicker to put reboot in the title! In any case, it turns off & on.

Could you just circumvent all this by leaving the router on? Modern routers consume so little power that the cost should be minimum and the headaches from not working should be gone
Having said that I have never had a phone forget the password to my network when I turn my router off, when you go into settings on your phone is the WPA password still there? It should be, I keep my passwords stored in Google servers so every time I change ROMs or devices I never enter the WiFi passwords to any network I often visit.... In other words your phone should store the password and remember it when you are in range of your router, power cycling it should not effect the phones memory of this password

I could and will leave the router on more, but this still definitely happen occasionally. Let's be honest, it's not the end of the world, but it does feel like a core bug.
Not sure whereabouts in settings the password would be / be visible? All the other routers I've ever connected to are there, I think, so the password memory function is otherwise fine. Which lends weight to this router/phone issue.... however it feels like it still ends up being a phone bug, since all it takes is for the phone to paste a saved string correctly. Wish I could get other people to replicate this but IDK how they would!
Is there an obvious option to store them on the google servers?

Open settings/WiFi/ and you will see all stored hotspots, long press anyone to see if it has proper info
You may have some setting in your router that tells it to disallow devices to connect after reboot, you can go through router settings and see what's going on there, often
192.168.01 or 192.168.1.1 just see your owners manual for proper settings, or go to the OEM website of router for some tips

Good knowledge man, thanks! Didn't know about long-press. Password says "(unchanged)" but if I hit "show password", nothing shows.
I'll check the router settings, that sounds like a promising avenue. Cheers!

Best of luck!

Lost WiFi at home

I have recently lost my signal from my WiFi at home but my phone still picks up the WiFi signals from the neighbors. I exchanged my first 3d for a new one but I still have the same problem. My ipod still picks up and uses the WiFi signal and was wondering if anybody knew why this maybe happening.
Thanks,

Try resetting your router. Or try updating the firmware of the router. Also try forgetting the network in wifi settings and then try logging back in. Or do a factory wipe.
Locked & Loaded
just turn wifi on and off, no biggie, works pretty well.
Check out WiFi Fixer in the app market. Solved all of my problems.
Whoa, before you do all that other stuff.
So your ipod works with your router? And your phone connects to your neighbor's router? If so then most likely your router isn't a problem, nor is your phone.
Android's wifi stack does a really good job of automagically connecting to the best available wifi spot. Do you see your wifi router in the Wifi settings? If so, long press and connect to it. If you have authentication set, then it will prompt you for a password.
Let's start with that then go with more, if needed, and will probably need more information that you provide.
My phone doesn't even see my WiFi connection, it can see all the other connections only... I've traded my phone in not only for this problem but other problems and this problem still looms. I'm thinking its in my settings that were transferred from my other phone? I don't know, help please...

Man its might be your router. Have ya even tried just resetting the router back to factory defaults??? Its a tiny pin size hole on the back of your router "or at least it.should be" Henceforth, find a needle or safety pin and press the that button for like 10 or 15 seconds and wailt 2 to 4 min. After that go to your wifi settings on your phone and click on your network name and chose forget. Now look for your new network name and which should be an open and unsecured network. It should have the manufacturing abbreviation in the network name so if its say a belkin it might be -belkin123 unsecured- also it should be open because when you reset the router it erases all of the security. Also routers firmware should always be upgrade. Not saying this will solve your issue but it might and its a really quick way to rule out if its your router.
Locked & Loaded
Some of the "perm-temp" root scripts caused this, if you used some of the older ones, you may be experiencing this.
The solution to it was to "forget" all your wifi connections on the phone, power it off/battery pull, then reconnect.
Of course, if this doesn't fit your scenario, disregard.

WIFI issues, new device

Hello wondering if anyone can help.
Bought the device yesterday, galaxy player 5.0
The only way I can connect to the wifi is if I disable WEP and have the router open.
When I use WIFI, either from the cell phone or my home WIFI using WEP, the device is stuck in obtaining IP address, as soon as I remove the WEP and have the router open, it connects.
None of my other devices have this issue, only this one.
Any ideas?
or
Should I return it?
Thanks.
I found that if my router was broadcasting its SSID my 5 would connect, if it was hiding the SSID it would not (just sat there searching for IP). Maybe that's the problem?
Mine has problem too on my belkin54g (open config), connect and disconnection all the time pretty annoying, i really hope there will come a fix out from samsung since it came with 2.3.5 update....
Thanks!!!
Thanks guys got it working.
Changed password on the router and did a reset to it.
Seems that did the trick.
Almost returned the player.
And the worst is that I had already installed a shield for the screen, 15 bucks!!!
Anyway, thanks for the response!!!
Hidden SSID need patch for YP-G70
Just install HiddenSSID Enabler from market, it'll work for YP-G70. You need run it once and get your hidden wifi connected, then can uninstall it. Looks like it is just a patch but really works.
I was under the impression you could use a hidden SSID under stock 2.3.5. Under Wifi Settings, there is the "Add Wi-Fi network" option, and it looks like it can be used for hidden SSIDs.

No, it won't work coz hidden SSID not supported by GB.

Try using WPA instead of WEP. WEP is ancient, and some newer wifi chipsets don't interoperate well with it because it's so old and it's been HIGHLY recommended to ditch it on routers for at least 5 years. WEP was known to be insecure almost a decade ago!

Someone correct me if I'm wrong but it seems like I remember reading a few years ago that hidden ssid's were not part of the 802.11 b,g, or n specifications. I thought that while a lot of devices had that function, it wasn't exactly "compliant".

Yes, that's true. I haven't seen any android smartphone on GB (don't know what's in ICS) can connect hidden SSID unless apply the hidden SSID Enabler patch. However, iphone / ipod has no problem.

wifi disconnect/reconnect fixed
On my 4.0 US, the wifi would disconnect and reconnect constantly. To fix it, go to ur network (on windows go to start and click network or type in ur IP address) and go to LAN settings. Change the dhcp lease time to 2 weeks or anything bit forever. It resolved my issue completely

Wifi priority over other devices?

Anyone know of an app that will boost my wifi speed at work over others?
Server speed is good just so many other devices and pcs it makes mine very slow. Its very frustrating 
Thanks in advance
Sent from my GT-I9300 using xda premium
you can configure this on your wifi router. if your wifi ap is basic one it might not have this settings. but most routers come with option to set high priority, qos etc.
Im at work tho mate.. im sure this can be done with just my phone
Sent from my GT-I9300 using xda premium
Cannot see how a receiver can receive priority over others without it being set at source .
jje
The whole point of Traffic shaping would be lost if any device can set itself to a higher priority.
Some packets can set an URG-flag which stands for least-latency routing instead of least-cost routing however it's still the router's call if he respects this and if yes how he treats them.
Something else is probably incorrectly configured. It's been reported several times that the S3 is very picky when several Wifi AP's with the same name (SSID) and in reach of each other are configured on the same channel (frequency). However most hobby-admins even know not to do that, so if your company is doing it you might suggest basic network training for your IT guys. (The basics of the Wifi protocol are in roughly the 3. semester at university)
You might want to try whether forcing the device to 5Ghz band will make it better since that band is far less crowded.
Also you could check WHAT causes the issues. Often it's not the bandwith by itself but either the router's connection table (a VPN to an external server is a very good but cumbersome solution) or the DHCP (use OpenDNS or Google DNS)

Because, according to your latest signature, you're on ParanoidAndroid which is not Sammy-based.
This information was lacking in your prior post.
Im using omega.. is this only possible on samsung based roms? Would it make much difference in me doing it? Id be happy to flash a sammy rom if it can get me a better connection at work. It takes around 10 mins just to post on here when im at work. And thats only after turning wifi off and on. I get good signal at work, and the speed tests are good. Hmmm

Internet working with browser, but not with apps

Hi Guys,
I have 3 android devices (xperia s, htc one x and a galaxy s3) connected to a wifi network. This is kind of a protected network and there is a firewall involved. Also the devices are getting IP via DHCP. The problem is that i am able to access web site via browser but when i try from the application, its showing i don't have internet connection. There is no proxy configured in this network. There is an IP filtering in the router which filters the IPs starting with a particular series. But the web site and the application which i am trying to use are supposed to use this IP series.
I've come across issues with internet connections on mobile devices. This might not work for you, but it has worked for me in the past.
I assume your devices detect all of the settings you need automatically?
If so, you may need to manually change some things.
1) Check your IP and make sure it's set right for your network
2) Check your DNS settings. Sometimes the default ones don't work properly.
Try:
8.8.8.8
8.8.4.4
These are from Google's OpenDNS and have served me well in the past.
If all else fails, check the network itself.
Hope this helps

Thanks for the reply.. but as i mentioned earlier, the device is getting IP and other stuffs via DHCP. I am not allowed to configure something statically. It has to come via DHCP. But the interesting fact is that an iPAD in the same network is able to get internet in both browser as well as applications.
Hey, if you need to get settings via DHCP then you should talk to your network admin for the settings

I am getting all the settings perfectly.. hope haven't read my first post.. i am able to browse via browser.. the problem is with the apps.. that y am confused about.. i know this kind of a problem may arise when we have a proxy configured in the network.. but we dont have a proxy in the network.. in fact an ipad hooked up to the same network works totally fine..
Did you get your apps working?
Nope..still facing the same issue.. internet is available in browser. but not in the apps..
There is no problem with your phone. I am sure that changing your router will fix this problem. Try another router with your internet connection and tell me if that worked.
Press thanks if I helped you!
We have tried that as well.. The situation got little worse with the new router. Now Internet is not working with ipad as well. But it's working in browser for both ipad and android. Another thing I have observed is that the Web pages load blazing fast in a windows and blackberry but the same site loads very slow in android and ios. As I mentioned earlier, the network is having a high security with firewall and encryption. Is there any limitations for android and ios to work with these kind of highly secure network??

Hi - I was experiencing this on a Galaxy Nexus with no SIM card only connected to WiFi - on a WiFi router that used to work.
The solution was to
1. Open up DHCP settings on the phone (Settings -> WiFi -> My Network -> Advanced)
2. Manually set them to something that's wrong.
3. Save.
4. Set DHCP back to what it was.
5. Save.
May not work for you, but for me, after about 30 seconds the app store and other apps started working again without having to do a factory reset or doing anything to my router/network.
Let me know if this helped!

WiFi authentication problem!

I can't seem to connect to my router at home. I'm able to connect to another router closer by,but not mine.I've tried changing encryption type from open to wep, to wap. But no luck. Every time it attempts to connect it says authentication problem.

Try looking at your router logs when the error happens to see why it's not authenticating. Try rebooting your router.
BTW wep and wap are not recommended for authentication...that **** can be cracked by a 12 year old. Use WPA2 personal.

So what youre gonna want to do is open your logs, clear them, try to connect on your phone, then look at your logs to see if the router even sees the attempt. It should show any errors as well.
What does your phone do when you try to connect?
edit: couple more questions...can anything else connect to your router? Also, your router is also a firewall. When you log in you might try and disabling the firewall feature altogether and try connecting.
I'm gonna try the logs now, and yes 3 computers are connected wirelessly. Also the phone says connecting...then says authenticating problem. I know my password is correct for sure. I'll check the logs now

Thats strange. Your router *should* be logging auth issues.
Have you tried forgetting your wifi network on the phone and reconnecting as new? And yourer showing password to make double sure its correct? If it is, the auth issue is probably a security mismatch. Router set for WAP, youre trying to connect with WPA2, etc. Double check your router how auth is set up.

Have you updated the firmware in your router? If so, check to see if there is any new firmware. Also what is the bit length of your passphrase? 8 or more characters. I would also have your encryption set to WPA 2 with AES not TKIP. Also try setting the channels from auto to a fixed channel, start with 1 and go from there.

I got my HTC One today and I have exactly the same router and I have exactly the same problem. Old LG 2X would connect like lightning. Tried different encryption, reset router multiple times, nothing.
Sorry if it is an old thread. sorry for bump.
I also had this "Authentication Problem" issue on my HTC Pico a few days ago.So,I also tried restarting my router, changing password and stuff like that. but it didn't worked.
out of curiosity I then switched my phone into airplane mode and waited few seconds and then back to normal. to my surprise, my phone automatically got connected to the wifi without any hassle. and hence problem solved.
