Wifi Issues

Hi,
I've had my N4 since a couple of days and have encountered some issues when using the phone on Wifi. I use connectify as a virtual wifi router on my laptop. My phone keeps loosing the data stream from time to time even though the Wifi symbol remain active. I either have to disable/enable the Wifi or restart connectify to get the data stream to work. Any suggestions how to fix this ?

It could be android's fault. I have the same problem on my Galaxy 3. The phone even loses the signal if I'm sitting in front of the router. It's noticeable if the icon shows sending data and occasionally receiving data, but not at the same time.
I have two other PCs in the same room and they don't have this problem so the router is probably fine.

My nexus 4 has great WiFi receptions. I was using the iphone 5 last week and i had issues connecting yo my home WiFi, i think because of some WPA or wep security, the iPhone would connect 2 times out of 10 when i turn on WiFi. It always connects with my nexus 4.

[SOLVED] Any idea what is wrong with my WiFi?

Hey all,
I just received my Nexus 7. I'm having trouble with getting connected. I can connect to the router fine, and the WiFi indicator turns blue, but I can't access the internet or occasionally will be able to load a tiny bit of data and then it stops.
I've been able to get a little better access by choosing a static IP instead of DHCP, but it's still "choppy." For instance using the Speedtest.net app I'll get a burst of data, then it flat lines. Burst, nothing, burst, nothing, etc. Chrome will sometimes load a page and sometimes it will time out. GMail has been syncing very slowly, every once in a while populating some more conversations.
I've tried my GNex at the same time and have no issues, as well as on my PC, so it's not an issue with my ISP.
Any ideas what I can check? I hope I didn't get a defective unit. I ordered from newegg and I don't know how they work with returns and exchanges.
Thanks in advance for any insight.

How close to the router is your nexus?

Fairly close. I show 2 "bars" of connection and in the WiFi panel in the settings it says the connection strength is "good."

Try moving right next to the router and let us know if the problem persists.

Issue persisted even when a few feet away from the router. However, performing a factory reset on the Nexus and power cycling the router seems to have remedied all the issues. I can connect via DHCP, browse the web just fine, and am able to get consistent data on speedtest.net at 20+Mbps.
Everything is working great now, this thing is awesome!

Glad to hear it!

[Q] Nexus 4 Wi-Fi issues.

First - Hi all, long time reader but this is the first time I've needed to start a thread - so sorry about my first post being a problem/Q!
I've not had my Nexus 4 long, but have got some pretty annoying Wi-Fi issues. I've searched for answers but it seems that people have different Wi-Fi problems and I just wanted to see whether my issue was a common one and, if so, is there a fix on the horizon?
My issue is that I can connect to some routers but not to others (work, home, most open networks)... when I connect it simply says "saved, secured with WPA/WPA2" but wont then connect.
Phones running stock 4.2.1 with franco kernel r28 and the things I have tried are:
Resetting routers
Assigning static IP address
Wi-Fi direct from my Nexus 7
Cleared cache from recovery
changed the Wi-Fi band from 'Auto' to 2.4Ghz and 5Ghz
Flashed new kernel
Very frustrating and because of my signal the lack of Wi-Fi has made me go back to my old phone while I wait for a fix... which connects perfectly to the networks (S3 running CM 10.1)
Is this a 4.2.1 issue - as seems to be the consensus with other Wi-Fi issues or possibly a hardware issue?
Thanks for any info!

There's one fix you've not tried which might work for you (it didn't for me). You would have to be rooted though, which is going to system/etc/dhcpcd and changing the permission on dhcpcd-run-hooks to read and execute from "others". This help some people out but turns out for me that my router isn't compatible with my phone. (DSL-2780).

I've noticed that some of the mobile devices(eg iPhone 3gs, SGS2) are quite sensitive to wireless channel which your router/ap broadcast on.
Try manually switch to channel 6 or 8 that solved my issue - I don't believe in incompatible routers usually problems are related to config.
It is more complicated with an access to the public WiFi as you can not modify the setup.

I have tried this on the routers which I am able to change the channel of and it didn't change anything.

Just to update.
I've now tried this and still can't connect to the affected Wi-Fi networks, probably going to have to wait for 4.2.2 to see if that fixes it...

I had troubles connecting to my wifi network here in my house, which worked pretty good with my galaxy nexus, what i did and worked was deactivating the option "avoid poor connections" in wifi advanced settings, you should give this a try

Fixed it for me

Thanks Chad, it was driving me crazy the constant data drops I had when trying to listen to streamed audio in XiiaLive Pro. Which worked flawlessly with my old HTC Desire.
Did as you said, and perfect now.

I too have wifi issues with my N4. We have several phones at home - an HTC Aria and believe it or not the SGS1, SGS2 and SGS3!
All of them connect with no problems. My brand new N4 will see the router but refuses to connect until I toggle wifi on/of serveral times in succession, sometimes 6-8 times!
I have avoid poor wifi disabled but it does not help
I really hope El Goog fixes this asap as it is very frustrating.

I've had this issue forever. Android phones hate low or overcrowded signal. Though my nexus 7 always works fine. Makes me think it is the lack of WiFi antenna strength

[Q] Connected to Network but No Internet Access

On my Nexus 10, about 2 weeks old, and running most current version of Android, non-rooted, I can connect to wifi networks, but I do not have access to the internet. It just started today after having no issues whatsoever since I purchased it. It also just happened randomly today out of the blue. For further information, in the top right corner where the wifi "baseball diamond" is, the bars are that grey/white instead of the typical blue. Which I know means that I am connected to the network but without internet access. I have tried restarting my device both powering it off and on, and simply restarting it by holding down the power button. I have tried turning wifi off and on. I have tried the same with airplane mode as well. None of it has worked. I was wondering if anyone knew of any fixes for this issue? Thanks and any help is appreciated.

First I would get the IP of the nexus by long pressing the Wi-Fi network.
Then go on your pc connected to the same router and ping the ip.
For Windows, press Windows, type cmd.exe, enter, then
ping 192.168.1.x
But put in the real address instead.
If you get a reply with a ms value, your tablet is really connected.
If it times out or you get 100% packet loss, then it really isn't connected, or is unresponsive on the network.

When the bars are grey it doesn't necessarily mean that you don't have internet. The bars only turn blue when you are connected to the Google Talk servers. They are blocked at my work but I still have internet access with grey bars.

It just started though and I didn't have problems before. And I am connected to the Google servers on my galaxy s3 just fine on the same wife network. And as for the other poster, how do I ping it on a mac?

So everything worked fine yesterday after doing this. But today it reverted back to what it was doing. Tried pinging the ip again but it didn't work and it gave me 100% packet error or whatever

The ping had nothing to do with it working again, it was just a coincidence. You're having the same wifi problem a lot of us are suffering.

it has to do with the dns settings of the network I am using. And it just seems to come and go in terms of working. Hopefully it is fixable problem within the software

I am having a similar problem, but it happens sporadically and oftentimes fixes itself after about 30 seconds. Is this a known problem and is it hardware? Also, sometimes when I go to open the play store I will get a "No connection" message with the option to retry even when I am fully connected (blue bars and everything). The retry almost always works too. I am curious why this happens and if the two issues are related. Thanks for the forum, folks.

Yes, this is a known problem many are experiencing and is most probably software, unfortunately google seems to have a hard time getting their fat fingers off their arse.

Same issue has been driving me crazy. I have to turn Wifi off and on again.
The other, really annoying issue is that when I turn Wifi on in my bedroom, it still connects to the living room router with terrible wifi reception, instead of the nice strong signal from the office router just next door, I have to tell it explicitly connect to the office one.

Alias_neo. Why don't you just rename the network in your room to a different name so the tablet can distinguish between the two

They ARE different names, that's what's bugging me. My SGS3 had no issue, but for some reason the N10 just prefers one once it's set.

Obtaining IP address after update to 4.3

Hi after updating to 4.3 connecting to my WiFi seems to just keep looping obtaining, authenticating, obtaining. This didn't happen in 4.2.2. Anyone know a fix?

Try another network. Maybe it has a problem with your network. Hit thanks

Try forgetting the access point and redo it.

Yes it works on other WiFi networks but does not mean the one I am having problems with is faulty cause other devices connect to it just fine. Not to mention it worked perfect on 4.2.2

WPA2 PSK. Also I want to note that this is a second router connected to the main one by ethernet and used as an access point

I had the same issue before 4.3 update. It was working fine after the update but today it happened again. I switched to static ip in my nexus wifi settings and its working fine. So i guess DHCP has the problem and im blaming nexus because everything else in the same network works fine.

I have the same problem with my old generation nexus 7. New one works just fine, galaxy nexus - just fine, xperia s - also fine, macbook pro - fine. I can't blame the network. Something is messed up. I tried a factory reset (as I'm selling this one) and it didn't help. also after quite some time of trying it wrote "Avoided poor connection" under the name of my network, but I can't alter the "Avoid poor connections setting" from the setup wizard.
Any help is greatly appreciated.

I think the problem is DHCP too. I used to use WPA2 for my LAN. My Nexus 4 appears to not connect to those networks anymore.

Tried to set a static IP address? And you could also playing with the WiFi frequency bands. Some reported they can't connect to WiFi on 5 GHz band. Could try the 2.4 GHz one instead.

In cases of weak signal, DHCP may fail when connecting. If this happens, move closer to the AP (stronger signal).
If you have 2 routers and use 1 as an access point, use the LAN (not WAN) port on the second router and disable the DHCP server on the same router. You can use the same SSID and float between them if the other settings match (encryption and password). Use 2 different channels as far apart as possible (like 1 and 11). On 2.4 GHz, only use channels 1 to 11. On 5 GHz, only use 36, 40, 44, 48, 149, 153, 157, 161, or 165. The other channels have FCC limitations in the US. Use WPA-2 only with CCMP (AES) encryption. WPA should only be used with TKIP, while WPA-2 should only be used with CCPM (AES). I have seen a lot of issues when mixed is used.
Hope this helps...

Thanks for the suggestions. While testing I was standing just beside my router, so no weak signal problem. What I did after many tries to connect was reinstall stock 4.3 but version which ended with the letter 'V'. I was unable to see my problematic android build version, because I was stuck at welcome screen. So the reinstall fixed it.
