[Q] Wifi signal high but no internet connection (Samsung Galaxy i5500)

I just upgraded my router to a wireless one. Firstly, it's connected via ethernet to a PC and it is happily getting internet access.
On my i5500 I get a strong wifi signal. Wifi Analyser shows the signal at max constantly. I can also connect with Gmote and it works just fine.
The problem is that I can't actually access the net at all from the phone.
So basically I know that my phone is talking to the router with no problem. It's just getting out onto the internet.
Does anyone know of a solution?

try logging into your router and change the broadcast channel to something else and test it again. it should be something like a/b/g mode... define a single channel and see if it works.

I had originally thought that was working. It did for the first few minute where I had connection but then it just dropped.
I have noticed that I have some very small bursts where I can connect.
Do you think that trying the different channels may be the solution?

I have the same problem. Have you found a solution?

Still no solution. I went through every channel and every encryption method.
So far I've found that having the channel set on 'Auto' and then disabling encryption seems to give me internet connection through WIFI for at least the initial period but it eventually drops. But that's also not always.
I've also Googled it to death and found nothing. If you do find the solution please post it here and I'll do the same.
Maybe we can help each other.

make sure you entered the right password of wlan.
use a pc to connect the router and in the wlan you'll find the password.

Ok, just to clarify. My phone connects to the Router via WLAN. In fact I can use Gmote to control my PC. So the WLAN connection is great.
The problem is accessing the internet when using that connection.

I had similar problems with a router last year. I resolved the issues by flashing DD-WRT firmware. The manufacturer's firmware was junk.

I had that idea but they don't have firmware for my router yet. I have asked them if they intend to make one.

Any chance the firewall on your phone is blocking your browser from using the Wifi?

I have no firewall on my phone.

Ok I've tried some new stuff and they I've had the longest connectivity so far (which is about half an hour).
First I made sure my Wifi wasn't set to turn off when the screen goes to sleep. Second, according to a forum I read, Netgear recommends channel 7. If that channels doesn't work try 1,3,6,9,11,13.
I then disabled encryption.
Fortunately no one near me uses Wifi at all and I've got the kind of walls that stop the signal from getting outside.
Anyway. It's working so far but I'll monitor and report.
[edit] And I forgot. The router was checking for firmware but it wasn't actually finding so I downloaded it myself. Seems that also made a difference.

Ok. I can confirm after 2 and a half hours my internet connection is stable. I even left half way through and when I came back it connected perfectly.
So as a summary here's what I did:
1) Get latest firmware
2) Change channel to 7
3) Disable encryption
I will change encryption and see if it still works

[All] PDA Net won't do downloads, anyone else?

While out and about, I have been bluetooth tethering using the Foxfi/PDA Net combo to stay connected while in 'pay for Wi-Fi' areas and as a passenger on trips. The one downside I can see is it says "No Internet Connection" and anything connected to the downloader program (browser downloads and store) will hold until I have Wi-Fi.
Anyone else try this? Anyone know if there is a fix, or if this is just how it is?
My details: Phone is Galaxy S II rooted with ICS, Tab was stock, now rooted with CWM.

I've been using bluetooth tethering using same scenario (epic 4G though), and when connectivity breaks, I have to check PDA Net and reconnect at times.
Sometimes data will hang and disconnecting and reconnecting will cause data to flow again. Other times my phone has issues and I have to restart FoxFI/bluetooth on it.
I always thought it was my phone though.. phone does reboot at times too. Using wifi instead of bluetooth is more problematic - epic runs only wimax or wifi but not both, so tends to have issues there as a 1st gen phone.

As far as my connection between the tab and phone, it has been solid. I guess that could implicate the phone. I have found that the systems tie themselves together much better if you let each program turn on the BT for the devices.
I'm disappointed that I can't download files from the browser or update programs on the fly.

w/ bluetooth, it is using a proxy service, so only browsers can communicate. app store updates or other app communications won't work in BT mode.
wifi tethering is the non-proxy way to address that..

Wifi stops working after being left for a while (still connected)

Having an issue with the Tab 2 where you go to pick it up and start browsing after it has been sitting around a while (not sure if the time matters, but it seems like after sitting for most of the day) and the wifi is still connected, but nothing works than needs data. It acts like it would if you had not internet connection. Toggling the wifi off and on will fix the issue and notificaitons and emails start pouring in.
Anyone else have this problem? I found a similar issue on the 7.7 forums but nobody reported a solution and I am not even sure if it would have worked on the Tab 2 anyways. I am thinking about making a script that toggles the wifi automatically if it detects it can't connect to the internet. But that is a little ridiculous needing to do that. It shouldn't be losing connection in the first place.

Hi Pirate
it's a bit depending on the ROM you have installed - but since Android 4 you have a quite reliable setting. The default behavior of Android devices is to deactivate the wifi connection when it goes to sleep.
Some ROMs don't recognize the disconnection and the switch/button still shows "Wifi on" although disconnected.
First step: go to settings / wifi settings, hit the menu button (top right three dots) and check the advanced settings.
Somewhat like "Keep WLAN active in standby" - set this to always.
That should solve it already under android 4.x
If this doesn't help, look into Play Store - search for "wifi keep alive". But for the SGT 2 you shouldn't need it
Greetz - Chris

It was already set to "Always" so I don't think that will help. I will look at that app to see what it does.

wifi turns off when not in use to save battery. I think it might be a default even if you have it set to always on.

The problem is that it never comes back on. Well it shows the wifi icon and the signal and everything but it just doesn't have any data connection. Any apps that use data act like wifi is off. The only way to get it to start working again is to toggle wifi or reboot. I also forgot to mention it is the stock ROM, only rooted. It got the OTA a few days ago too and it has happened since then.

You're not alone

It's the same effing stuff people suggest to every wifi glitch out there.
To people who think it's due to the wifi sleep policy: although I've set it to always, why would wifi not resume, after screen is turned on? It's not the wifi that gets disconnected, it's the internet (or the download speed) that stops working.
To people who suggest it's a power saving feature under low battery conditions: Sorry, I've tested it while charging and with full battery.
To people with the above two arguments: Connection to some routers works perfect with the phone. Like when I turn on the hotspot on another phone, the wifi works great. Also, wifi on the other phone from the same source (laptop used as internet access point) works well.
To people who suggest resetting the router or wifi on phone: The internet does start working again, but only for a few minutes. Even if the screen is turned on, the internet may stop working mid-download.
The actual situation is that the phone disconnects from the internet, but keeps showing a connection to wifi. Like I used connectify hotspot to create an access point, and after a few minutes, the phone moved from "connected clients" list to the "previously connected clients", even as the phone showed connected to wifi with even the download arrows blinking, but no internet (or download speed). This only happens with certain sources (of wifi). And other phones may work well with the same source.
I have tried (several times and in different orders and permutations) the following to no effect:
1. Resetting the router.
2. Resetting the wifi on laptop.
3. Resetting the wifi on phone.
4. Restarting the phone and laptop.
5. Static IPs, gateways and DNSs. (Even though the problem was not with connecting to wifi and even internet works momentarily after resetting wifi).
6. Turning off items controlling wireless network in wireless connection properties.
7. Turning off firewall.
Waiting for a savior.

I know this isn't super helpful but I had the same bug you describe on the previous version of carbon. When I updated to the latest it seems to have stopped.

Same issue. also using connectify and also tried all things you have described. If you find any solution please let me know.

I had the same problem on my Huawei Honor. You need to set static IP in wifi settings (when connecting to AP, press "show advanced settings").
Mine settings were:
IP adress: 192.168.1.75 (make sure other devices are not connected with this IP)
Gateway: 192.168.1.254 (it could be different. Use the same as you're using to connect to your router)
Network prefix length: 24
DNS 1: 8.8.8.8
DNS 2: 4.4.4.4

No option for static IP in connectify

There is no option in connectify for static IP and in USB wifi dongle also there is no option to set static IP.

1. I have had the exact same issue for (atleast) the past 2 years. Have survived by repeatedly turning wifi on and off.
2. I too use connectify. This issue doesnt seem to happen on every wifi connection (just like your case). Even more specifically, it seems to happen ONLY when I connect my phone to the hotspot created via my laptop (connectify).
3. Even when the internet is actually working, some apps do not seem to recognise that(take some time to realize it is working), while others are able to connect instantly. Specifially, whatsapp is unable to send/receive messages for about 1-2 mins, after which I receive a whole bunch of messages at once.
This does not seem to be an issue due to connectify as well. I have tried creating a hotspot from my laptop without using connectify as well, but unfortunately, nothing changed. Further, this does not happen when my phone connects to a hotspot created via connectify by some other pc. The wifi and internet work perfectly fine when connected to a hotspot created via my friends computer.
Further, this problem happens only when a mobile connects to the hotspot. Doesn't occur when another laptop/PC connects (not sure about tablets).
I have looked into every nook and cranny on the internet, explored every forum for any working solution, but have been unsuccessful. In fact, this is the first place where I saw the exact same problem as mine, and was wondering if you have found any solution to it .

I'm having the exact same prob on my ZTE Grand x V 970
It started when i had kitkat and i couldnt even "fix it" restarting the wifi, i had to reset the phone in order to have my wifi work for like 2-5 mins and then stops recieving data, tried to reconnect and stays on turning on wifi.. Now i changed to the stock Rom and the problem is still there but at least now i can "fix it" restarting the wifi connection until certain point.

Issue sharing internet with Connectify from PC
Go to:
Control Panel\Network and Internet\Network and Sharing Center
On the left column, click on CHANGE ADAPTER SETTINGS.
You should be in: Control Panel\Network and Internet\Network Connections by now.
Then click on: Microsoft Virtual Miniport Adapter and click on Properties, then click on the 'Configure' button in the 'Networking' tab. From this window, go to the 'Power Management' tab and uncheck 'Allow the computer to turn off this device to save power'.
This works for me. Try this out
If this doesn't work further, you can try out mHotspot for the same purpose.

I've had the same issue, with the wifi saying it's connected even though it isn't.
This thread is 4 years old and this issue still hasn't been fixed. What a shame.

Same issue here on OnePlus 3 even after factory reset.

I have this same problem after the security patch Mid March to Jan 1, 2019. The WIFI doesn't show in the top status bar, but toggling wifi off/on fixes it till the next overnight. I did make one change to my wireless about that same time and that was moving the min connect speed from 6Mbps to 12Mbps to help with bandwidth issues being cause by devices using low speeds and having several SSID broadcast. My S7 and Tab A both work fine - so I think it was something in the security patch.

WIFI and mobile internet at the same time

This seems to be an easy one first, I just did not manage this working.
When I am connected to device via WiFi (which is not connected to the internet) I cannot connect to mobile data. The device somehow keeps trying to use WiFi only for internet connection. Obviously switching is NOT OK, as I want to be connected to the device. Imagine it is a drone remote controller or a dashcam or a wifi cam.
I tried Wifi+ but that is only changing to another wifi with internet on or switches to mobile net. I also tried mobile net always on, but does not help either.
Any idea? I do not even think this is Honor related - this should be easily working on any Android device.

sounds like the same to me , but i think, its impossible , you can connect both at a time.. but phone always tries to get internet from wifi..

Yes. It's quite impossible to do that. Wi-Fi and Mobile Data at the same time. Speedify on the play store let's you use both for downloads and Internet. Doubt it'd solve your problem tho

I understand now it might not be possible. It is by default like this in Android. It is kinda stupid, though.

Wi-Fi dies when using bluetooth to listen to audio?

This is my second phone to have this problem. First was my old S4, now my S7 has the same problem. Basically, I want to watch YouTube or Netflix on my phone over Wi-Fi, and I want to listen to it on a bluetooth headset. But after a few minutes of watching/listening, my Wi-Fi connection always dies, I get that little exclamation point next to the Wi-Fi symbol in my notification panel, and the only way to fix it is to turn off Wi-Fi and turn it back on. It'll work for another couple minutes, then die again and need to be reset. Bluetooth stays connected the whole time and never drops. It's just the Wi-Fi that gets dropped. If I turn Bluetooth off and just listen via phone speaker or wired headphones, no problem, Wi-Fi can cruise all day.
The research I've done suggested that 2.4GHz might be causing a problem, but my network is 5GHz. Another suggestion was to switch the phone to a static IP address, that didn't help. I'd also read that Android has problems with IPv6, so I went to disable that in my router and discovered that it's never been on.
So, I found three solutions on my own, and none of them worked. Now it's time to reach out to the brain trust here. Does anyone have any idea what might be the problem? Vanilla S7, no root or ROMs. Thanks!

Have you tried the usual first step in troubleshooting, have you tried booting to recovery and wiping the cache partition?
You can also try flashing the stock firmware for your model number via Odin.
