Strange Wi-Fi problem

Hello
I have a strange problem with Wi-Fi in my rhodium. I have to wait about one minute to load any data from Internet (for example load google page in web browser). It heppens only after i soft reset or switch on rhodium. I enable Wi-Fi and then try to load google or something other - I wait about minute to load page. After that everything works fine. If i switch off Wi-Fi and switch on again it also works good. My problem heppens only after fresh wi-fi start after reset. It heppens at all web browsers and others applications. I tried also hard reset. I have stock rom 6.1. Someone can help me? I have no idea :/

Does this only happen with a single wifi location (i.e. your home), or anywhere you use wifi?
If this is related to your home wifi, you might be able to sign into your router's management portal page and watch to see if the router shows an active connection with your TP2 as soon as the phone says it's connected, or if there's a delay there..

I didn't check it with other location than my home network - becouse I don't switch off my pda when im outside, but i will try it Today i rebooted my router and pda and then turned on wi-fi on pda. After that.. wi-fi worked without wait, i repeated it 3 times and it works lol. Router see connection of pda without delay. I have no idea now what it is but im happy that it works now. I reboot my router often so i dont think that it could be a router problem which disappear after reboot, but time will show. I will write if this problem comes again.

[Q] internet connection through wifi problem

I upgraded from my G1 to the new G2.
I am in the military and currently deployed to Iraq. I pay for wifi internet in my dorm. Using my Laptop or my G1 i am able to connect to a wifi service out here that i pay for. once i connect i pull up the browser and it will redirect me to the log in page for the server (where we have to enter a username and pass to allow acceses to the internet. without entering it we are only connected localy). when i use my G2 i can connect to the wifi hotspot no problem, it shows me "obtaining IP adress" and then says "connected to balad-hotspot" just like it would on my computer or G1. but when i pull up the browser it just goes to a "web page not available" for anything i type in. it wont automatically redirct me like both my laptop and G1 do. i even tried typing in the adress it pulls up on my computer when it loads the log in screen, but still shows me "web page not available" Does the G1 and G2 use the same browser? and if so why doesnt it redirect me? what else could cause this problem or fix it please?
with the new OTA update for wifi calling and sms messages you can see why i would love to have this issure fixed. also if i go to a free wifi area (such as a recreational center, where there is no log in neccessary, just connect and go) i have no problem connecting with my G2. so i know the wifi works with it. it just wont seem to redirect my to the log in page or allow it to come up.

firstly: thanks for what you do for our country.
try a different browser. i recommend dolphin HD

thank you!
hmm ok, ill try looking for that tomorrow. can be found in market?

Yes, it is in the market

Wow, they have WiFi at Balad now? Man, when I was there 3 years ago we had to wait in line for a computer! As the others have said, try using a different browser. I'm always switching between the default and Opera depending on what page I'm trying to access.
Oh yeah, if it's anything like Google Voice, the new update may not work for WiFi calling, depending on what country the IP address you snag is registered to. I had Google Voice on my G1, and as soon as I went to Europe and tried to use it on a WiFi hotspot, I got a message saying that Google Voice was not usable in the country I was in.
Stay safe and don't eat too much Taco Bell or Burger King!

haha ya, but its a HUGE rip off. way expensive and slow as can be. but its really our only option to get interent in dorm so im a sucker and bought it.
and for the goodle voice, hmmm i have it on my laptop and it works with this internet. dont know if it will be different with G2 but we shall see.
I tried Dolphine HD and Opera and still having the same issue. it only ever pulls up "web page cannot be displayed" The Internet guys out here said it was my browser. i confirmed with tmo that the browser is the same for the G1 and the G2. yet it works with G1 and not G2. and still wont work with any of the new browsers. Im stuck and this blows!!!

[Q] HELP - Can't log into protected Wi-Fi – Galaxy S3 stock ROM

I have a T-Mobile Samsung Galaxy S3 rooted with the stock ROM running (Deodexed_T999UVDLH3.zip). Everything on the phone is running fine, and I have no problems accessing the Internet on either Wi-Fi on my home or public networks or over 4G.
I am having one odd issue, though. In my office, we have a Guest Wi-Fi Network that I have typically connected to. I get 4G in my office, but the Wi-Fi saves on my data plan. Logging into the guest network requires opening the typical splash page and clicking on the button to accept the general terms. Now that I have routed the phone, I cannot log into this guest network.
When I try to log into the wireless connection, I can open the browser, and the splash page comes up, but when I click on the accept button, the phone vibrates once, sits for about five seconds, then vibrates three times quickly and shuts the browser down. The same thing happens if I click the link to open the terms and conditions page. The Wi-Fi connection under settings shows as connected, but I cannot get any data to or from my phone. The Play store times out, and the browser will only load the splash screen for login again.
In searching this forum, I found posts that instructed clearing out all of the cache and the cookies, and I have done this. It did not resolve the issue. I did not find any other posts that seem to relate to this problem.
I am a relative newbie when it comes to rooting, and this forum has been extremely helpful. I'm hoping that someone may recognize what is going on with my issue, and can point me in the right direction to get it fixed. Any help you can provide is greatly appreciated. Thanks!

Wi-Fi bars full but no internet connection

Hi. I just bumped into this issue and I am really annoyed because I don't know why it appeared. The story goes like this: I wanted to search some app on the PlayStore and as always, I turned on the Wi-Fi, waited a couple of seconds and the full signal bars appeared, as they should and the network appears also "Connected". But, when I try to acces the PlayStore, it keeps loading and loading, the same thing goes for Google search, mail sync or anything else that involves an internet connection. The catch is that the problem isn't with my router, because it is working properly, my laptop and my sister's phone can access the internet. I have tried forgetting the network and re-entering the password as well. I don't know if it is related, but at the same time when the internet was not working on my phone, a message appeared on my screen at a 30 seconds interval, and the message was "Backing off 30000", "Backing off 45000", etc. I rebooted my phone, I wiped my phone, I thought it would help, but it didn't. I hope you can help me solve this problem. Thanks in advance.

Returned home from short trip, Wifi connects but does not function

As the title says, I didn't change anything about the phone's configuration when I was out, didn't download any new apps or change any settings that would interfere like this. No one else has changed my home network in my absence.
Nevertheless, most of my apps, such as Instagram, the Play Store, Twitter, Wikipedia, Chrome; almost all their requests time out. There seem to be short windows where data will load, and Instagram appears to load comments and post metadata, but no images. It's basically unusable. Occasionally an exclamation mark will pop up over my Wifi symbol in the notification center. Strangely, I can still reach my Steam and Battle.net authenticators, but the moment I try loading the Steam app, nothing comes up. It's like the device can only handle plaintext over Wifi.
All of the apps work fine over cellular data.
Also, there is a toast that appears whenever I restart my phone that says "Power On" that I've never noticed before. I was rooted using Xposed, the only modules I used were Snapprefs, Xinsta, Physical Button Music Control, and Greenify Experimental Features, all of which I uninstalled. The toast still appears with the latter two disabled. Only other rooted apps I had besides Xposed were Nova Launcher, Greenify, Busybox, and Root Checker Basic, all of which have been removed but Nova.
I am running 6.0.1 with the latest update.
Any ideas? I am still within 15 day warranty so I could theoretically return the phone (which I was contemplating doing anyhow since 10gb of functional storage is a bit too small for me), but would rather not have my hand forced, and eat into my cell data plan.
So far I have tried forgetting the network, wiping cache/dalvik with TWRP, removing the Google VPN, resetting all network settings, and a couple things I can't remember offhand now. Any suggestions will be appreciated.

First, if you want to return your device because the 16gb model doesn't have enough space, go ahead.
If it is mostly because of this WiFi issue, I wouldn't return the device, it is almost certainly the case this is some configuration issue (possibly in concert with some Android bug) which can be resolved.
Is it possible when you came home the device connected to a neighbor's AP and thus you couldn't use data, but it wasn't immediately obvious, so you ended up forgetting your own network and reentering the config, but the key was off by a little, and from that point on, it was just assumed the wifi config was correct?
When you say Google VPN, are you using WiFi Assistant and Project Fi? Have you tried disabling auto-connect fir the WiFi Assistant?
Have you tried using the old Lollipop DHCP client (perhaps your IP address got used by another device and the new Android client doesn't handle that well?) Just grasping at straws.
Have you tried turning on Bluetooth while WiFi is on? Perhaps there is a bug with them working independently of each other in certain situations.

I am 100% positive I am on my own home network and that I used the correct key. I'm not sure what you mean with regards to the rest of the 'config', I have always used the standard wifi configuration, just typed in my key and had it work.

I actually forget what it was called, it was under Settings>Wireless&Networks>More>VPN. There was one entry there with an icon. I forget the name of it, but the icon looked like a stock Google icon and I think it had google in the name. I am on Project Fi, not using any wifi assistant (at least not in Advanced Wi-Fi Settings), but when I tried to toggle that option on just now, something called "VpnDialogs" crashed, so I assume that VPN entry was that. But again, the assistant wasn't on.

I did, when I first googled this was one of the things I found, sadly it did not help.

I don't use Bluetooth, and trying to toggle it off/on from the control center just gives me a repeated "unfortunately, Bluetooth Share has stopped" error message.
I have decided to get the 32GB 5X since I do want more storage, but since I would like to be able to root my phone again and use Xposed, I would still like to hear any other ideas you have for troubleshooting this problem in case it reoccurs.
I reflashed the latest update to see if that would fix it, no dice. When I send the 16GB model back I have to factory reset it anyway, so I suppose I'll know if that does it.
What puzzles me is why I can load text from instagram posts that have been posted while I've been having this problem, but not images. Makes me think that maybe my connection is being super throttled somehow rather than non-functional, but my PC's speeds are normal. Perhaps some internal part is damaged? I do have a case and it hasn't taken any serious tumbles, but it has had one or two small falls from maybe 2 feet high.

It is easy to test if you have some network connection vs none.
In terminal or adb shell
ifconfig wlan0
ping www.google.com
1st command will tell you (among other things) if your wlan picked up an IP address.
2nd command will test whether you can send ping packets over your connection.
I'm sure there are millions of ways of doing the above, I just gave you one example.

Strangely, the solution seems to have come from factory resetting my router. I ruled this out initially because my other old phones were working fine on wifi, my phone is now getting WiFi again.
Now to figure out what the hell this "Power On" toast is about...

I've encountered something similar where the router runs out of NVRAM space because it has recorded too many DHCP clients, it won't hand out new IP addresses, but if you are existing or already have one, it is fine.
