Nexus 4 (and Android in general) grey wifi signal? (Wifi problem) - Android Q&A, Help & Troubleshooting

Hi... I have a Nexus 4 and I've had numerous other Android devices in the past as well.
The problem with all these devices is that they refuse to push any notifications and the wifi signal turn grey (which means the phone is not connected to the Google service servers)
but this happen ONLY on my school wifi network - whenever I turn on 3G, go home on a break or off-campus, the phone get blue signal again and sync like crazy
So this is obviously a wifi problem - not a phone problem (so please refrain from suggesting that I should flash new kernel/rom etc.)
On the other hand, my roommate iPhone still receives push notifications from Apple server. So the problem is exclusive to Android (I should say this is mobile-OS-cist)
So if anybody have any idea about what configuration on the wifi network might have led to this, I'd be more than grateful! Thank you

your need the username and pass for school network

Usually, schools has ITS OWN NETWORK, after you connected to the AP, it doesn't mean you can use the network now. You have to login (with the username and password that school provide) using your browser. But usually the Username and pass are not allow to give to student, you should apply one form your school.
So,
Step 1 connect to AP the signal will remain grey
Step 2 login with school U&P ,
Step 3 you will see the signal turns blue(or other colour), enjoy

Stock T-Mobile Amaze Wifi and/or E-Mail Issues?

Hey Guys.
I seem to be experiencing strange issues with my T-Mobile Amaze 4G and was wondering if it is only me.
Before I continue, I just wanted to note that I already performed a Hard Reset and received the OTA update a couple of weeks ago with no change in the problem.
It seems that everything seems to work well as soon as I restart the phone...but after a while, I notice that my e-mails do not get refreshed/notified from the e-mail app unless I actually go into the app itself.
I have set the e-mail app to check for new messages every 15 minutes with no peak time defined....that is....it checked every 15 minutes all day any time of the day.
Second issue is with Wifi. It seems flaky and I find I must turn off/on Wifi periodically not matter were I am getting Wifi from (i.e. - Home, Work, Coffee Shop, etc...)
Is it just me having these strange issues?
Is there a fix for it?
Thank All.
I don't have email issues when I am connected to 2G/4G.
I do, however, have issues with WiFi. Specifically the corporate WiFi at my work. It just won't connect. It gets stuck in the authenticating/disconnecting loop. Very annoying as this is the only phone I have not been able to connect to the WiFi at work. All of my prior phones connected with no problems, e.g. Motorola Photon, HTC Evo 3D, HTC Touch Pro II (Sprint and T-Mobile versions), iPhone 3/3GS/4. All of them will connect but my Amaze won't.
Is this par for the course or could I have a bad Amaze, again? I am on my 2nd one by the way. The first one had the same auth/disco loop problem, too.
My WiFi connects at work when it feels like it, which isn't often. At home its just fine.
I have the same thing happen to me as well between Home and Work Wifi.
It would seem that Corporate Wifi systems usually require the "Use secure credentials" to be enabled in order to connect (Settings, Security, Use secure credentials).
If it isn't checked...then no Corporate Wifi will connect.
It would seem that HTC released an update for the Amaze today (Dec. 12).
I have updated my phone...we'll see if it works any better.
Wish me luck...
Apparently HTC is rolling out an OTA that includes WiFi calling: http://forum.xda-developers.com/forumdisplay.php?f=1319
Not sure if it's T-Mobile USA only or not...
Thought I'd post my observations...
My wi-fi at home (wpa2 personal) works flawlessly. Wi-fi at work (wpa2 enterprise) is able to connect and works great but after 40-50 minutes gets stuck in the authentication loop for unknown reasons. While in this auth loop, it seems to be in a transition state - neither wifi or TMO data mode and no synching occurs. Turning wifi off then back on will resolve but is a pita.
However, once the enterprise wifi is enabled (using credentials) the advanced power menu stops working - the long press of the power button functionality. Clearing the credentials usually re-enables the power button long press functionality, sometimes this requires a battery pull to restart.
Even with these small (at least for me) inconveniences, the Amaze is the best phone I've ever had!

You bet I do...still flaky.
I actually have to run the e-mail app to get my new messages.
A real PITA.
Did the ota update and WiFi seems to be better, more testing after lunch.
It's still not an instant connect like at home, but it does connect much sooner now at work.

Do you connect using WPA2 Enterprise at work? If so, are you able to enable Wi-Fi Calling?
I called 611 and they were not much help. Only thing came out of that call was maybe the WPA2 Enterprise enforces additional security for UMA (WiFi) calls resulting with REG99 error for me. I'll try from home with the WPA2 Personal connection later.
I'm reading TmoNews and it says IMS WiFi calling. 611 told me UMA...
Tried the WiFi calling from home (WPA2 Personal) and it works great. The router at work must be causing the REG99.
we're on a WEP network at work and at home so not sure why home works but not work. It may have to do with the firewalls and all that, but I'm not sure.
I ran into the same problem with email syncing. Here's a work around...
Use "tasker" and get the plugin for it called
"Synker"
Make a repeating profile that links to Synker and voila. You can control when and how often it syncs...

My WiFi performance stinks with this phone. I just got the 1.43 update today and it's not any better. With my old Nexus One I didn't have problems, but when connected at home (shown as WPA/WPA2 PSK) I get lots of time out errors and just about every action in the Market loads very slowly. When it finally does start a download they go OK but getting opening an app page or getting a download to start takes a long time. It is very weird.
I'm running stock.

I don't think it's the phone. I run stock and average 6-11Mbps down and 7-8Mbps up with my WPA2 Personal router connection.
I'm having data connectivity issues on the corporate Wifi (enterprise 802.1x encryption). I can connect initially, but after about 10 minutes (sometimes as much as 30 minutes), I'll lose data functionality but the wifi stays connected. My old Vibrant works fine at work, but the Amaze drops the data. It seems to happen when I switch access points. My sign-on credentials are fine. I can't seem to find any other similar issues out there and support was no help (t-mo, htc, etc). A factory reset didn't change anything. My home wi-fi works fine so this issue is a bit frustrating. Anyone else experiencing this issue? I'm feeling quite alone on this issue unfortunately....love the phone otherwise. I'm running stock.
I'm having the same problem with the router at my work. It will say connected but not data is sent or received. Any other phone works just fine on the same router. My amaze works just fine on any other router. I've disabled all security access on the router at work and the only phone that seems unable to connect to this router is the amaze. (I've tried 2 other w/the same result)

I have been using Beast mod for 3 days now and email has not been syncing, along with facebook and twitter. the sync icon has been on for a few days but nothing is syncing properly. Could it be something to do with a custom kernel?
Just to throw my 2cents in, I was struggling with connecting to the wifi at home, it would connect ok but then never transmit any data. Everything else connected and worked fine, also connected to other routers with the phone and no issues. Long story short, I limited my router to just B and G (no N) and it fixed everything. Phone works great now.

[Q] Wifi icon gray, Talk not working ... NOT A WIFI ISSUE THREAD!

So I picked up a Prime today (running 4.0.3), and I'm having a weird issue... I can connect just fine to wifi, everything works properly, except two things:
- My wifi icon is gray. Always. Regardless of where I am, the network I'm connected to, etc.
- Talk doesn't connect. The error is "Connection interrupted -- status updates temporarily unavailable"
I have cleared Market and Talk data. I have removed and re-added my Google account. I don't have PDANet or any other tethering software. I've checked my wifi connection to make sure there is no proxy or anything. My speed is just fine! I've disabled/reenabled Background Sync. Syncs on the Google account work just fine.
I'm at a loss here... HALP?
I'm having this problem too.. did you ever find a solution? anybody else?
Mine does that when Im too far away from the router but it goes blue when i get closer.

I ended up turning off wifi, deleting the files in /system/etc/wifi, and rebooting. Had to re setup my wifi connections, but somehow in restoring a backup (or the ICS upgrade) the saved profiles must have gotten corrupted...

I'm having a similar problem. My icon starts out blue and everything works fine, but then after letting it sit for a while, my icon turns greay. Have not been able to figure it out yet. Pretty frustrating to set your tablet down and 15 minutes later have it stop getting notifications because it's disconnected itself or whatever it is when the icon turns grey.
I have my wifi settings set to always remain on while sleeping.

I tried but didn't work. I think we had different issues. It didn't sound like you could get a connection at all, while I get a connection that goes bad after the tablet has been idle for a while. Turning off/on wifi allows me to reconnect.
My android devices do this typically due to the firewall settings on whatever I am connected to, my wireless at work or example.

That is my assumption as well. I have the same issue but i figured it out. Its all you r wireless settings on the router. I have changed the broadcasting channel and since no more gray antennas. Its all i guess channel interference.

I've had that happen before, but in this case it was a constant 100% of the time thing, regardless of firewalls/connection/etc. Just something weird with the wifi profile on the device. I'm more convinced it had to do with restoring HC data after being upgraded to ICS.

I always wondered why my cell phone did the same thing, and in my searches, gray just means that it's not connected to Google's sync service. Now, while I agree with that to an extent.... I too have noticed on my cell phone and Prime (when tethered to my cell), that if either end is gray, I have non-functioning internet. This even happens if I have full bars and HSPA for my data connection. I personally have never noticed this on any of the 3 wireless home routers that I've connected to, however.

Same experience here. Grey typically means you have internet but no google services, but on my prime grey means no internet at all.
I've managed to get my wifi connection stable by using an app in the market called Wifi Keep Alive. I'm not sure if this app has any impact on battery draw in sleep mode, but I didn't notice much of a change after installing it. I left my Prime on all night last night which has always caused the grey icon, but my icon was still blue this morning and internet was functioning

Internet issue, grey bars not going into blue bars

I've had my prime for about a month and a half
I've started to notice an issue with the wifi.
I've tried reading up on google for people with similar problems. But it has been hard to isolate my problem midst the myraid of wi-fi problems primarily those who have issues with the wifi strength being sub par.
The deal is ... Start of the day, walk onto campus, log on to the wifi. Now in order to use my university's wi fi I need to enter my ID details for it in order to connect. So normally I go into Dolphin and click google, and the web authentication page will come up. So I type in my details and the internet works fine, the grey bars turn to blue.
I've read a lot about the difference between grey bars and blue bars, like grey bars means it's connected to the internet but not synced to the google account. However for me, grey bars mean absolutely no internet.
Then further on in the day. I move to another part of campus, then suddenly I've got no internet. I'm guessing because I've disconnected from 1 particular region and attempted to connect in another. Or the transformer prime goes into some hibernatory state while it's unused on standby in my bag.
I can't even get to the authentication page. The signal is fine as shown on wi fi analyser, but it just doesn't transmit everything. I try restarting my tablet, forgetting the wi-fi location and reconnecting. Nothing works.
Still says the connection is fine, but no information is getting transferred.
The same thing happens at home with my wireless internet.
Where the internet bars stay perpetually grey. Now the solution to the problem, is to restart the router, then the internet is fine. However in university, this obvioiusly is not a solution. And I depend on the wi - fi for my university studies, so having no wi fi for the tablet pretty much renders it useless.
Just today, at home. The internet was working fine and I had to restarted the router. And now I've got the problem. If I were to reset the router, I think the problem will cease. Nothing wrong with the signal. It's connected, just no information being transmitted.
Now I'm hoping it's something on the tablet that I can change. If I really have to, I'd factory reset. I've read something about this issue on XDA, where the solution was something to do with static IPs. Now I'm not too tech savvy and have no experience in rooting or playing around with ROMS, so I didn't really understand.
If there is anyone out there has come across this probelm, I'd appreciate any help.
As well as whether factory reset has ever worked for anyone

In home iv always had blue bars, but in my university, they are grey too. I figured this was because of the proxy, but even after configuring the proxy settings in the tablet definitions, i only could get the broswer to worrk, because i think those definitions only work for the http port. In order to be able to connect with other apps, i needed to download an app called proxydroid, but you need root for this. I dont know if this is related to your problem but it may help. Good luck.
Yeah me too when i. Home or somewhere else their green but wen i log into my schools wifi i get gray bars and no internet so what i did os get an everclear portable router lol .. i think its the schools wifi
Blue = full two way communication with Google services
Grey = partial or no communication with Google services
I would suggest removing your account from your device and then adding your account again. We have been able to test that Google services should work on the secure network.

Wifi blocked at work any bypass?

OK so work have blocked several of us from connecting our phones to wifi. Now we have a router her but can not access it so image they blocked at the main offices where they manage the network. Their are several houses that have their own routers etc but connected to the same network if that makes sense.
So my question is first how would they block us and second how can we bypass it?

Several ways to block access to a wifi routers.
Ways to access the network would be bring your own from home,and plug it in to the network.
To many ways to block you out to know what they have done.
Sent from my HTC Wildfire S A510e using XDA
Probably two reasons why they did this -
1) Prevent rogue devices connecting to their network, i.e. devices they cannot control what is on them and therefore could introduce viruses into the network or allows others to hack in and steal data etc.
2) Prevent people connecting personal devices for personal use, downloading files, facebook etc. Using company time and resources for unproductive personal tasks.
Probably easiest to ask them why and to ease the restrictions.
On the how:
You can control what connects to what on a very fine level - by device, by what it does and who it can talk to.
Ye I understand why. They blocked us as their network is really slow and rubbish but when we do nights and no one is using it its nice to be able to connect as no signal their. Just wondered if their was a way to get around it. They seem to have blocked all phones that were connected but one that was has been able to reconnect which is a blackberry.

How to by pass works blocking phone 2 options
By pass I've discovered! May not work for all
WARNING TRY AT YOUR OWN RISK!!
#1 way I've discovered (in my office)
(Other wise try bring your own wifi router and setting the ssid to company's name )
If you have a pc or Mac computer and plug Incoming Ethernet port into LAN port not WAN then from 1-4 LAN port into pc/Mac Ethernet )
Try hiding your wifi router either in tower box or in desk try to be not so obvious leaving cables everywhere , don't just leave out in the open for everyone to see..
What I did
(I've hide the router in the under my desk using 3M double sided tape and tucked the cables away so there not hanging down)
#2 way ( works anywhere you can get a wifi signal)
My. Discovered by pass :
I got a wifi repeater/ range extender
I've programmed it to my work network with their ssid and password
Then
On the repeater / extender
Your new Access Point
I used the same ssid but used a different password
(At this point you have created your own AP , which logins to your network wifi and then
Now
When I go home I just unplug my repeater and lock it up in my desk
Good luck Jason
Ps: option #1. if you need more help try YouTube if your confused what to do with wifi router
SEARCH "using old router as a wifi extender (or as second AP)
My boss already block ssid wifi for usage at handphone, only laptop can connect that wifi. How i can connect wifi via my handphone? Currently i use i phone 6s.
Any trip for unblock for connect to my phone?
What kills me about my situation is some dumb ass did streaming video one day and ran up like XXXX gb of data so naturally they started giving a damn about who was doing what... I got banned/blocked even though I've never streamed... I'm assuming I'm blocked... got the right password and my old phone said authentication failed. My new phone it doesn't say or haven't found where it says yet... I can't bring in my own connection as I don't have a office of my own and the building is too big and metal for the mobile signal to make it to my location...
edit: According to my idiot boss they're getting strict I guess and just blocking most stuff... ?

What is wifi network "0x"?

I've noticed that whenever my wifi is on, and also the "always scanning" option is on - my phone suddenly connects to a network called "0x".
It doesn't really work - there is no internet. It happened in different places, inside and outside my country.
Does anybody know what it is?
UP
Old post, but happened something similar to me. Sometimes when I have just connected to my wifi network and I look on the menu it displays "0x". Your phone was probably connected to a public wifi or just bugged.
Still doesn't explain it though
In my understanding, the 0x is a garbage SSID that indicates that WIFI configuration data is obsolete.
Ite wonderful if u ask me ☺?
I booked a hotel room and when i arrived thr...my device got connected to Ox wifi and it has over 2Mbps speed...so i was curious about this Ox wifi hotspot so i searched on google and i found ur post and now i am more curios about it. What the hell is going on lol...
.
In my opinion it may have some connection with rooted devices bcz my device is rooted and i have samsung s8 as well and it neither finds this Ox wifi nor gets automatically connected☺:fingers-crossed:
Edit: As far as I see, it might a bug of Android with special cases of bad connection. Like it connects somehow, but can't get SSID. Turning on "avoid poor wifi" seems to fix it.
Same here. I've saved two wifi connections: one is my home network, other one is a network of free wifi transmiters offered by my ISP (UPC Wi-Free). My phone is Motorola Moto G with Android 5.1. It's not rooted and never has been.
I live around elder people and there were no strangers so I doubt some grandma suddenly established malicious network. Probably a bug, but the bug of what? Android? Some external software? I use Nova Launcher and Wigle Wi-fi. Do you?
0x seems to be prefix of hexadecimal numbers, but it doesn't make much sense. It wouldn't mean "hexadecimal zero" (which would be 0x0), but "hexadecimal nothing".

I've seen it too, then the actual SSID of my home network appears. Maybe Android shows '0x' when it doesn't know the name of the network it's on.
