[Q] WiFi connects but no web

So I recently got this phone and it came with Android 2.3.6
I stand next to my old school and it catches the router TP-LINK### and connects, gathers IP address and the signal bar displays as good.
Finally, when I try to access the web it doesn't seem to work and says I need to check settings. What else would I need to check? Anyone know?

Nope, I've tried that app WiFi Manager but it's still the same. Minutes ago I was next to another building with good signal and again, the same problem.

Ok thanks.
I just got into some advanced options thing in there and I see that "Static IP adress" is unchecked, should it be checked?

I will check those and try tomorrow, thanks. In the mean time more suggestions are welcome.

So I just succesfully connected to my current school's router and the web is accessable and downloading is just perfect. That sure is a relief that it's not a problem of my phone.
Gonna try checking the static IP address option later on the other school.

I feel your pain mate,
I've had the same problem. I discovered that my phone was leasing the same IP from my router over and over around every 2 minutes due to DHCP. Then, after a while the connection would be ****ed up, grey wifi bars, sometimes still blue. Everything pointed to having a working connection. But doing anything involving an internet connection on the phone resulted in NOT being connected at all. It drove me crazy aswell and after a couple of hours of Google Fu I resolved the issue by simply assigning a static IP for my phone and using Google's Public DNS servers.
Give it a try, maybe it'll work for you aswell.

Long press on your network and tap on 'modify network' - tap 'advanced setting' and scroll down a bit, there are a few more options.
To assign a static IP you should have basic knowledge on how to configure your wifi router and such. Can't really help you there, either you know what you're doing or you don't. Things differ from router to router.

Ok! Thank you very much! I do it!
EDIT: Bulls**t!!!! don't works...

Well, that's unfortunate. I'm still baffled on why it's acting up at all. My phone was fine for almost a month before it started acting up, and I didn't change anything on my phone. Same ROM... and all of the sudden, WiFi started acting all weird.
Also I just discovered that changing 'Keep WiFi on during sleep' to never, does absolutely nothing. WiFi still stays on during sleep.

I don't know... it's the same case... I restored all the phone, lock de bootloades, etc And I updated by OTA, one by one, to 4.1, when the problem begin again... grrrr
Any idea pls??
After a lot of test.... the problem is only in jelly bean 4.1.1 y check a lot of roms 4.0.4 and works right, but in jb...

3g data and wi-fi problem

Hi guys! :victory:
I have got a problem with my samsung galaxy nexus stock version,
without root or unlocked bootloader.
The problem is about the 3g connection and wifi when I turn off the display.
3g: when I turn off the display, after a few minutes, the phone loses the data connection. It is like it goes in power saving mode because when I
turn on the display the signal icon turns grey and after a few instants blu. In fact mail, notifications, and whatsapp's messages are notified with
a 10-15 minutes delay.
wifi: same problem, when I turn off the display I lose the signal. When I turn on the display, the wifi icon disappear for an instant, become grey and then blue. Until it turns blue I don't get notifications.
I have already done several factory resets, disabled power saving settings
and I don't use any power management apps.
SMS and calls works fine.
help me please

Welcome to the club. I have the exact same issue and had a thread going about this. Nothing i've done has solved the problem. Even gone right to complete stock rom. Same problem. I noticed this started happening with 4.2. Before that i didn't have a problem. Mine only happens on Wi-Fi, no issue on mobile network connecitons. As well it happens no matter what router i'm connected to. This should be in the Q&A and troubleshooting section though...
With W-Fi make sure its set to always on in advanced Wi-Fi settings and that minimize power is unchecked as well as avoid poor connecitons. Might help for you.

Yeah my problems aren't on 3G. Rarely have I had that drop out. It's happened, but that's once a month tops.
I've gone to the point of buying a high end router to exchange my old router. No difference. I had a Cisco e4200 and now an e6500. Also had a D-link Dir655. Happened on all of those. Happens at Starbucks and at work too on their routers.
It's software problem for sure. And it can be fixed. And complaints have been put up on Google code site. There are at least 5-600 posts on that topic with people suffering the same problem. Why don't they fix it? No idea.

UPDATE
To let the wifi work, I have downloaded the app "wi-fi fixer" and using it I
fixed (just a workaround) the wifi issue!!:good:
But what can I do about the3G connection?:crying:

do you know if this problem is fixed with a custom rom??

Not for me. It's a kernel issue though since the kernel is what takes care of the Wi-Fi. But no kernel or rom has ever fixed it for me. I'm trying that wifi fixer though now.

I have the same problem.. But mine is really bad.. My 3G drops for a long time or it just never comes back, I have to reboot several times.. Not sure wat the issue is..

Regrets in advance since i am not writing for solution, rather sharing same issue.
Brother I have same issue and what a diagnosed (I am an end user and not developer of programmer) that Data Sim is not compatible with Internet use and GPS navigation.
It is impossible to use navigation or maps for more than 30 seconds.
Tried service provider, they only reintalled software and retuned it saying its okay.
If you find any solution or if somebody else has a solution please do share with me as well.

Today my grand was in my jeans pocket and to my surprise i heard samsung boot animation sound ...
Took out the phone and found that its restarted by itself ...
The phone was idle

Whatsapp Web not connecting when phone is locked

Hey guys,
Trying on this more active forum...
I just bought the S21+, overall great phone except couple of issue with Android Auto and Whatsapp.
I was able to fix the Android Auto issue (wouldn't connect, had to remove the latest Google Chrome updates) but the whatsapp issue is above my paygrade.
I scanned the QR code and everything works but as soon as the phone screen goes black, whatsapp is slow and disconnects often. Not completely disconnected as after I send a message perhaps 10/15 seconds later it gets set but still not responsive as before (S8+)
Any idea?

you can try other software to watch network connection status, if no problem, maybe that's compitability issue on s21+

Thank you, do you have any recomandation?

Not sure if you managed to fix this but in case you haven't.
You need to make WhatsApp a non-optimized app in the battery settings. That way WA will consume as much battery as needed to stay alive and to connect to WA Web.

No, it shouldn't matter. I was just trying to provide an option.
I really don't have any problem when its on mobile data but I do have problems with Wifi from time to time cause WhatsApp Web is poorly implemented with the app.
Sorry I couldnt provide any help.
