[Q] Wifi issues

My wifi is very spotty at best. It always seems to say it connects just fine but it won't let me actually use it. I just went and stood right above my router and had full wifi strength and couldn't browse the internet. Are there any solutions to wifi issues or do I probably just have a bad wifi chip?

There could be a ton of different reasons why you can't connect. There might be a compatibility issue (some devices just don't get along), there might be an issue with security (you aren't using WPA2/AES on your router), there might be a channel issue that can be fixed by trying another channel on the router, the list goes on and on.
What kind of troubleshooting have you done so far? What router do you have?

Running a netgear WNR3500L with WPA2 encryption. All I've done so far is a simple restart of the router.
EDIT: downloaded and used wifi analyzer to see which channels were open and they looked to all be about the same. I switched it to 6 for tests without any improvement. My router auto detects the best channel to be on. Any other advice?

[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?
Sent from my DInc via XDA App

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

WiFi authentication problems

I have been having issues with all my android devices and connecting to me WiFi. They accept the password but will continue to "obtain IP address" or "Authenticate". I have been able to get all my devices to connect by unplugging the router and plugging it back in, but I don't want to do that every time. I take my tablet to class with me, so it loses the home signal and then i have to unplug the router upon returning home. Thinking logically, it i either my internet speed or my router.
Any thoughts on a solution that doesn't involve unplugging my router every time my tablet leaves the house?
-Router problem?
-Network problem?
-android problem?
-security Problem?
I have
-Gnex(vzw)
-Nexus 7
-Belkin N150
-500 kilobit network
-WPA/WPA2-Personal (PSK)
-Known working password
Thanks for the help

It's a well known Android problem past 4.0 ICS, and does not happen with all WLAN routers but with some. Sad to hear it affects current Nexus 7 devices aswell.
Maybe you can try out your Nexus 7 on a friends router and see if the problem persists, if not, getting a new & cheap WLAN router might be the least worrysome solution.
Patch it directly into your old router (typical RJ-45 patch cable) and disable the new routers DHCP server. Voila, done.
The only other possible reason I can think of is if your current router is not broadcasting it's ssid. Hiding the name of your WLAN in it's broadcasts is something that gave me troubles past-ICS too. I resolved it by simply broadcasting my routers ssid, even though it lets my neighbors see my network (naming it random letters and numbers).

WiFi Unstable Issues

Anyone having problems with WiFi? My phone seems to easily disconnect from WiFi with the excuse of "Avoided poor internet connection". And it seems to have become worse after the v15e update. My phone is the H959 model from Singapore.

Give us some more info
Whats your router?
You are connected at 2.4 or 5ghz?
Are your channels congested? Try to find a better channel using wifi analyser

It happens on any network. I was on holiday in the US, and it kept dropping the connection. I thought it was just because hotel WiFi are just ****ty in general, but it happened at home and at work too.
The WiFi at home is an ASUS RT-AC68U, and I'm connected to the 5 GHz channel, and channel congestion is not a problem. 2.4 GHz is congested a lot, but the disconnect happens on both 2.4GHz and 5GHz. Most of the time, I would pick up the phone, and try to access a website and it would take forever. After a while it would say "Internet connection unavailable at *wifi name*". Then after a reconnect it usually works, and loads the page instantly.
At work, I'm wearing an Android Wear watch and installed the network change notifier, so every 10 minutes or so, my watch would tell me that I have disconnected from the WiFi and after 5 minutes it will connect back again... Signal strength is excellent, channel congestion is horrible, but it shouldn't disconnect that many times.

My house WiFi is an ASUS RT-AC68U, and I'm connected to the 5 GHz channel, and the channel is pretty much clear. 2.4 GHz is congested a lot, but it happens on mostly any network.

You seem to have a good rooter. With all my >snapdragon 800 phones and tablets wifi works perfect .
Connection between phone and router is 433mbps. Before you hard reset your phone try to change channel . And try to keep your connected devices at minimum 2 or 3. You can also try pseudo static ip instead of dhcp

All my other devices, be it computers, tablets, older phones, do not have this problem. The problem I face is really similar to this thread below:
http://forum.xda-developers.com/g-flex2/help/wifi-woes-t3197144
I suspect it is due to a setting that is found in KitKat to "Avoid poor connections" but that is not found here. When doing a speedtest.net I can get 200+ mbps, so speed is not a problem. My phone just doesn't like to stay connected... Probably will try a hard reset, just need to backup my data.

Wifi roaming bug is back on S7

I have two wifi APs with the same SSID and it will stick to one of them with next-to-useless connection while standing near the other one. which would have much better connection.
This works fine on my Nexus 9 tablet and even better on my iPad and my wifes iPhone..
I tried some possible workarounds like Always allow wi-fi roam scans but I didn't see any effect.
This fix for SG3 might work but i havn't rooted.
Even more solution suggestions
Doesn't this bother anyone else ?

wifi has a bug in 6.X and its been talked about before.
my problem some times when i want to connect to another wifi it connects for a 1 sec and then drops it
i turn off wifi and back on and it will connect

i'm trying the app "Wifi roaming fix" but i think it causes the wifi to disconnect for a couple of seconds when it switches.

Strange that this seems to be of no interest to anyone. Is there indeed nobody who is using one or more WLAN APs in addition to his/her WLAN router? I can't believe that.

I have two APs (Main router and 2nd router as AP) but not for more coverage, my main router pushes 5GHz wifi, the second AP pushes 2.4GHz for older clients that can't connect to 5GHz
The 5GHz router is placed on a wall in the middle of the house and the entire house has great coverage so no need for more APs

I have more APs in my house with OpenWRT and 802.11r aka Fast Roaming configured and roaming between all my APs is working perfectly with all my devices.
Note 10.1 2014 Wifi, S7 Exynos and all other also.
With APs configured as "normal" ap with the same SSID and key i had the same issue as you mentioned.
I think your phone dont know that it could roam between your two APs.
If you could not run OpenWRT on your APs for 802.11r, you could try to enable WDS on both APs even if your APs connected by wire.
