Strange Wifi Issue - Nexus 5 Q&A, Help & Troubleshooting

Hi Team ,
I am having this very weird problem since morning
" I was using the wifi at my brother`s place just fine for a few days now . This morning the internet went dead slow ( on all the devices ) so we reset the router and it started working fine. Now the network is being detected / connecting just fine on all the devices at home ( 1 galaxy tab ,S4, S3 , Note 3 ) but my Nexus 5 is not even detecting the network. I was on stock Rom with element kernel. i did the following
1-) Played around with all the wifi related settings
2-) Factory reset twice
3-) Flashed a few kernals ( including the stock one )
4-) Flashed Mahdi Rom
5-) Flashed Stock rom
But the problem is still there. My Nexus 5 is not even seeing the wifi network ( it was working fine since this morning ). Just to check around i also created a hotspot network on my laptop. All other devices are able to see that hot spot except for my Nexus :crying:
Also
As i am visiting my brother outside country , i do not know anyone else here where i can go and connect to a wifi network. Although the phone is seeing Near by wifi networks just fine. I also cannot check the router settings etc as my brother has lost the id/ pwd
I am getting out of ideas now , and also bombarded by the family on using a nexus instead of a galaxy phone ( not that i care :silly: )
Any help would he highly appreciated

Check if your wifi settings are on 5 ghz or 2,4 ghz only, check if your mac address is shown and try to flash franco kernel

Tried both the 5ghz and 2.4 ghz frequencies but to no avail. I can see the mac address , flashed the latest franco kernel but situation is still the same .
Edit :
Just got the problem resolved . Apparently the phone does not have a sim installed ( i am out of country ) . I just inserted a local sim in and things are back to normal
Very strange problem. Is there any explanation to this ?

[Q] What is happening to my device ???

Hello xda !
The last 36 hours have been interesting for me I am in a bit of a situation with my phone.
Problem 1)
I use videotron ( canadian telco ) they have generally kinda crappy reception. Yesterday at work I lost reception which isn't uncommon my desk doesn't usually have reception all day. I noticed though that it didn't come back all day and by the time i got home I still didn't have any reception. I would occasionally get some bars but my phone would state 'emergency calls only' in the notification window.
I was using a custom rom... infinity rom.... which i had been on for a few weeks. using the uckd1 radio....
I have since flashed multiple different radios and roms all with the same issue. I get little to no reception and if i do it says emergency only. when i search for networks i do not see videotron although i see other local providers. so my radio is working just not seeing a specific one.
I called my telco to see if they blocked my imei and they say they haven't. my SIM card works in my other nexus s ( from work ) my work SIM card does NOT work in my phone.
So through trouble shooting I am back to a stock image with an unlocked bootloader and still no reception.
Problem 2)
Restoring to stock to trouble shoot the above problem i had to remove CWR... I have an unlocked bootloader however when trying to adb into my phone in fastboot my win7 pc or a mac at work would not see my device. My win7 pc at home when trying to install the google bootloader driver i cannot find it in the list of drivers after i have downloaded and selection the usb_driver folder from the sdk.
Closing)
I would appreciate help with both problems. If I can get the bootloader driver going I will install CWM and install some backups from a few months ago to see if that resolves problem 1.
If anyone has had any similar problems and solved them please let me know. Any sight is appreciated.
thank you
I have partially solved problem 2 !!!
I have gotten the android 1.0 driver changed to bootloader interface. however when flashing the recovery img it just sits on <waiting for device>
any help would be appreciated guys

If drivers are correctly installed waiting for device is usually a sign that USB debugging isn't activated.

I had turned this on, however once i got the driver working i tried superboot 1 click root which had worked previously with my device, although this time it seems to have caused a problem and I am unable to get passed the google logo in the bootflow- to now verify usb debugging is activated...
YaY :/
I can still get into my bootloader fine and DDMS sees my phone so I am pretty sure debugging is on.
So Problem 2 has been solved I am back into my phone.
I still though am unable to get real service. I My phone will show bars but it states emergency calls only. When I search for networks videotron isn't there.
My SIM card works in other phones other SIM cards don't work in mine.
any ideas ?
Yesterday i found same problem. You just have to do one thing put you sim card and also put some paper on the upper side of sim the sim will fit in boot your device this work for me.

Problem Solved !!!!!
Videtron blocks IMEI's the conflict with the rogers network, they will let you piggy back on rogers for a month or three then once they get tired of paying rogers for giving you service they block your IMEI on the network :/

[Q] Samsung s3 hardlock after a day?

Hi
I am an unhappy user of a Samsung S3 since yesterday. I have received the phone, unpacked it , charged it. It powered up ,worked fine. This is not my first Android device so i decided to root it after half an hour of use +/-.
Win7(64bit)/ Odin 1.85/ CF Root SGS6 v6.3. Rooted fine. Time for a new ROM ? think so too CWM recovery/BACK-UP installed CriskeloROM SIII ICS v2. Works fine, can receive calls make them, text message , browse net through 3G.
But the problem starts with wifi - it connects to my router,obtains an IP adress but there is no internet. LAN is connected because i can see other users on the network and access a GoFlex drive which is shared on the home network.
I was stupid enough to root the device before checking if the wifi worked, so i have no clue if it worked before i rooted and installed the custom ROM.
Anyone have any thoughts, on things i could carry out in order to get the wifi working?
p.s from the router side of things everything looks fine.
Here is some info which is completely useless to me , but might be usefull to you.
BASEBAND
I9300BULF1
KERNEL
3.0.15-671647
BUILD #
IMM76FD.19300XXALF2
ROM
cRISKELLO SIII ICS V2
Thank you for any attempts to solve this problem

WiFi problem. Need help badly!

Hi so I recently flashed my buddies one s with cyanogen mod and pacman ROM and the ROMs both work flawlessly other then the problem with wifi. The wifi doesn't seem to want to hold a connection. Is there a radio I can flash to get this working? He keeps complaining about the wifi dropping right after connecting. The problem only happened after I rooted and flashed his phone. Any help would be appreciated.

I have also this problem with my One S. It seems that it doesn't want to connect to all WiFi networks since WiFi doesn't work in my home but it works in my school. Someone suggested to me that the problem is bad version of wpa-supplicant binary. I didn't have this problem until I flashed CM10.2 Stable. Sometimes WiFi won't connect before I switch WiFi off and back on. Currently the only solution seems to be changing the settings of the WiFi router if possible. Make sure that WiFi channel is 11 or smaller and try changing the encryption settings.

[Q] WiFi problems help

I just recently brought myself a moto g LTE coming from a nexus 4 device.
I would like some help or advice anything to sort this little problem out I have.
I unlocked the bootloader flashed a few custom ROMs but what I noticed is the device is connected to the WiFi but no data is being transfered. I try using chrome or play store but I get nothing loaded. I have to reboot the phone a few times then it works and then it stops working again after a while.
I don't seem to have problem with any of my other devices I've even changed the channel on the router but I get nothing.
Using data on the phone is fine, but nothing for WiFi.
I hope somebody out there can help with this.
Thank you

If this happens in all the roms you flashed, try 1.) another router (to check if that is the problem) or 2.) flash a different radio.
If this happens on just this rom, 1.) make sure the rom is suitable for your model or 2.) ask in the designated rom thread and ALWAYS mention your model, rom and rom release version. Search XDA on how to logcat and make a proper bug report.
Good luck
