wifi issues on N4 possible fix?

for those with wifi 'broken' try to change your router settings to WPA2 personal (TKIP+AES) that seems to work for me now,
other settings 'broke' the wifi
this might be just an issue with must me and my router
*spoke too soon: still broken, it only works certain times, mostly it just spins when i try to connecto to online
the wifi icon keeps flashing a black dot... that means the wifi is NOT working right? it should be just a solid blue bars?
on wifi advanced settings, WPS Pin Entry - what is this and do i need to enter that pin on my router?

still no luck with wifi on my network after flashing back to stock 4.2 from 4.2.1
same 'broken' wifi
might be this phone's wifi hardware is incompatible with wDDRT router?
Firmware: DD-WRT v24-sp2 (10/10/09) std
my other wifi devices work perfectly fine, so im really stumped
in phones advance wifi settings it has this WPS entry - what is this and is it somehow not allowing me full wifi?
i can view playstore,, it checks and loads my gMail but it won't connect to websites
it takes so long to download and install apps from playstore, i have to hit cancel, redownload, reinstall to get it working,etc. its not 'instant' like normal 20Mbps wifi should be
ran speedtest.net app and it wont connect to any servers
if anyone has clues to why my wifi is broken, please PM me thanks
it get a blue 3 to 4 bars on wifi signal but it keeps having this 'black' dot flashing in that wifi signal bar, (what is that?)
shows connected to my wifi at 72Mbps at good strength

I found my solution: in my router I unchecked the option WMM (Wi-Fi-multimedia)-settings (2.4GHz b/g/n). After I activated it, my data speeds increased enormously. Try it & report!

Public wifi and my work wifi working perfect with n4. So it definitely my routers wddrt firmware issues with n4... still gottta figure it

My n4 will not connect to any of the WPA2 AP's around here.

I have the opposite problem. I can connect to my WPA2 router at home just fine but cannot connect to the WEP wifi at work. Well, not reliably. I've gotten connected twice, but was unable to recreate the conditions.

I had speed problems with my 5GHz band at home. Connected, but couldn't get over 1Mbps on my 30+ connection. Connected to the 2.4Ghz band and I get significantly faster speeds. Haven't had problems connecting though.

I've noticed similar behavior, seems like my 5ghz signal strength is much weaker than my 2.4ghz signal according to my n4.

So this n4 is picky about. Certain WiFi networks.configs
Sent from my Nexus 4 using xda premium

Sometimes, my N4 loses wifi connection at work. It's inconsistent. My work wifi is open but MAC filtered.
There have been 3-4 times when I noticed that it lost wifi connection. I had to turn off wifi radio and back on to reconnect.
OTOH, connection to home DD-WRT wifi router is rock solid.

Set lease time for as long as possible, it normally this is 2 weeks..

very strange !!!!
can you test to flash back CWM recovery and test again the wifi ?

Hello, I am also having problems with WIFI. I've tried a lot of things (change the router configuration, the cellular exchange kernel, etc ...) but I could not fix this problem. Can you give any more ideas? I've even thought about buying another router but can be giving the same problem.
I used my wife's phone as a router and it works normally, but when I connect directly to the router from home and he trasfere data only for a few moments and then transferring data, although still seem the symbol of wifi connected.

I found changing a setting on the Nexus 4 seems to have remedied most of my WiFi issues. Forcing the WiFi frequency band to 2.4GHz only instead of Auto appears to have done the trick for me.
In WiFi if you select Settings and Advanced under Wi-Fi frequency band there is an option to force 5GHz or 2.4GHz with the default on Auto.

will android switch to a better wifi if available?

Heyho, i currently have access to my wifi as well as to my neighbors network as my wifi gets weak while i am in the garden. I feel like android isnt awitching to my neighbors wifi automatically. Only when my wifi is completely gone, android will look for a new one.
I thought about making a task with tasker which looks for another wifi as soon as the current wifi strength goes below 25%.
Or is/should android do that aleady on its own?
Thanks

In wifi -> Advanced settings there's an option to avoid poor connection. I have no idea what it actually does, but give it a try.

I did the test with my router, which supports 2 frequencies.
Assuming both networks are saved in the phone, it connect automatically to the one with better signal or look for an alternative if signal is lost.

Thats what I mean, it will connect to the other WiFi if the connection is lost. But if the connection is crippled (bad) enough to not handle a music stream, but still "availabe" it will not switch to the other WiFi eventhough that other WiFi has 100% signal strength ?
I activated the "use wlan only if good strength available".. lets see how this works

I have multiple APs in my house and the only way I've ever got it to switch is by toggling wifi off and on (or loosing the first signal completely). This is an Android issue IINM, my GS2 and my N4 both have this issue.

I tried the "do not use weak WiFi".. didnt work.

It has never worked for me either. Didn't work on my GSM GNex or with the N4.

I think it's how most WiFi clients work, otherwise if you were in the middle of 2 equal signals, it would spend more time disconnecting and reconnecting creating a DOS attack on the 2 AP's and leaving you with no data.
As for 2 home wireless routers, use the same SSID and authentication settings for both, and put one on channel 1 and the other on channel 11.
Make one a AP only (no router, no firewall, no dhcp server) and connect it to a client wired port on the first one. You can roam between them like people in large offices do.

or I try to make a tasker profile
if wifi strenght below 20% and another wifi is available with more than 30%, connect to that one.. then wait 5 minutes ?

[Q] Is there any solution for WiFi not connecting to certain networks

My Nexus 10 works fine on most WiFi networks, but there are a few places where it fails. The N10 sees the network which has fine signal strength. It goes to the "Connecting" state, waits 30 seconds or so, and then drops back to "Saved".
I would think the network had non-functional DHCP, but I can connect with a Lenovo notebook instantly from the same place to the same network and AP.
The router that causes the problem is a Cisco 1200 series AP, operating vanilla 802.11g, with an open network, in the 2.4 GHz band.
I have tried all the Wi-Fi-related options in the N10, and removed and recreated the connection. I have found nothing that helps.
Has anyone that has seen this issue found a solution?

Seen this a million times, and it's one of my lingering dislikes about Android (although to be fair, I've seen the analogue -- much less -- on my iPad as well). Toggling the Wi-Fi state on and off like mad (or Airplane Mode) usually does the trick for me...eventually. Have you tried rebooting the router (relatively sure you've have, sorry) or using an app like Wi-Fi Analyzer from the Play Store to see if there's any channel interference? Mobile devices don't always deal well with overlapping channel use.

I cannot reboot the router because I have the problem in a public place (an airport). I do not have the problem with my own router.
I do use a WiFi analyzer, and there is no interference issue. The AP is on a clear channel, and the signal is very strong.
So the only and best solution it to turn Wi-Fi on an off rapidly until it works? Really?????

Never said it wasn't stupid. It's possible that the airport is using a network hack to facilitate its captive portal (I assume it uses some kind of gateway?), and Android is really bad about network "misconfigurations."

Any suggestions for prioritizing Wifi networks?

Now what I mean by this is if I have multiple overlapping wifi networks I want to be able to select which one the phone will prioritize its connection to
Why this is important for me is at home I have my 5Ghz network and my normal network(2.5Ghz I think).The 5Ghz network wont travel as far as my other network but speeds are much better
So basically I want my phone to use the 5Ghz network until its no longer available.Another example of how I want to use this is at work I have access to my private wifi around my desk and corp wifi around the office
The corp wifi blocks access to certain content so by prioritizing my private wifi the phone would stay connected to it unless it loses coverage and then it would switch to the corp wifi and vice versa
I tried a bunch of apps I could find and none seem to work too well. I know some versions of CM had something like this but cant seem to find anyway to do this properly on stock ROMs which I figure would be a good feature
Any suggestions would be welcome

My case the only way I have found to solve that was enabling roaming assistant on my routers (RT-AC88U's) to help my devices switch to stronger signals, and smart connect to switch from 5ghz to 2.4ghz and viceversa when bandwith on that band is saturated.

Unfortunately that would only help for the area around the router. I'm looking for a phone based solution
I would figure in this day and age this should be a default feature

Yeahp... that's why I have subscribed to your thread to see if someone has phone based solution

Tried the app again to see if I missed something and it pretty much has nothing from what im looking for. There is no option to prioritize specific SSID. You can prioritize 5Ghz or setup specific signal thresholds but what im talking about is an app that will prioritize SSID
So for example if I have WIFI 1 and WIFI 2 both have great signal but I prefer WIFI 1 unless it has no service then and only then it will goto WIFI 2. Once I go back in the coverage area for WIFI 1 it switches back

Found this app and so far so good.
https://play.google.com/store/apps/details?id=app.com.superwifi&rdid=app.com.superwifi
It has the option to prioritize by SSID
Will test a little longer

This also seems very promising

You know Tasker? With the autotools plugin you might be able to do this. You could make it search for ssid and if xx ssid is available, connect to it. I don't have time for more in depth before the day after tomorrow, but quote me if you need help.

Lets you prioritise 5ghz, and also set at what difference in signal strength it should switch to better network

Thanks but mainly looking for SSID filter vs signal or 5Ghz.
You can have different SSID for 5Ghz vs regular which is what I do at home but at work 5Ghz isnt available to I mainly need to prioritize one SSID over another unless its not available

Did you try Tasker o Automate? (I didn't try it yet, that's why I'm asking). Tasker is a very powerful tool which can help on such things.

I use Tasker but only for simple tasks such as when bluetooth connects change audio info
Otherwise many of the options go over my head

Eh . I'm going to buy AC88U later this month. I wanna know. So. I know that if you enable roaming assistant on 5ghz. It'll switch your phone to 2.4 when the RSSI match the settings. But the thing I don't know is. If we can do the same for 2.4ghz. so when it reaches how much high strength it'll disconnect it. So making the client connect to the 5ghz. Well I know smartconnect can do it. But smartconnect disables the channel selection. Thanks [emoji4]

Wifi issues, router/modem stops working

Hi. Have an S8 plus exynos. Have had big trouble since last phone update with wifi. Get this "!" Icon besides the wifi symbol.. router stops workin for all internet and ofcourse phone wont work either. Tried setting manual static ip for phone and router but no help. So im stumblin in the dark here. Any suggestions??
Thanks in advance.

Recent system updates have made this problem more frequent for both the S7 and S8.
If your router broadcasts both 5mh and 2.4mh signals (i.e. an AC router), and your connection messes up when at some longer distance from the router or through multiple walls, change router settings so that the 5 and 2.4 signals have different SSID names. Turn off any "smart connect" option. Then find the 2.4mh signal in your phone's WiFi settings and make that auto reconnects, and forget the 5mh signal. This forces the 2.4 connection when you're home which has much longer range than the 5.
If that only partially helps, go into router settings and switch the 2.4mh signal channel from auto to one of these three: 1, 6, or 11, whichever seems most stable when you reconnect.
If your router has Qos (quality of service) settings, be sure your phone is in a higher priority level.
Lastly, be sure your router has the latest firmware.
Doing all this fixed the problem for me but may not be a universal fix for everyone. Good luck!

Another thing to try is assigning your phone a reserved ip address via your router settings. This makes a faster connection that should work every time. Router sees your phone's MAC address and gives it the same ip address connection every time.

If the problem affects all devices connected it sounds to me like your router has a problem. Try a factory reset, set it up as new and see how it goes. If it's still acting up, you probably need a new router.

How to select only 2.4mh on phone?

Indeed, also try to connect your S8 to a local, public wifi network (like in a bar or coffee shop) and check if it connects there.
If it does, then the issue is certainly with your router.

You can't if the SSID is the same for both frequencies

have you tried to install latest baseband?
