[Q] Wifi Issue

Hey guys, i've been having problems getting my wifi to work with my new nexus 4 since I got it.
The phone can find the wifi and connect to it, but the speed is EXTREAMLY slow, or even sometimes it just doesnt work although it shows an excellent signal on the status bar.
Is something wrong with my phone? I have yet to try it on other wifi networks though.
I tried to set the frequecy band to only 2.4GHz but it doesn't help either..
Any suggestions?

Try rebooting the modem/router and wipe the cache on the phone in recovery. That helps sometimes.

Okay, thanks.
I just checked the device with the WiFi at school and it worked great, reached almost 20Mbps, so I think there's no problems with my device, maybe it has something to do with my router or network settings.
I have an Edimax br-6424n router, should I buy a new one?

[Q] Nexus 4 data connectivity issue

Got my phone a few weeks backs.updated it to 4.2.2 .There is this strange issue with regards to 3g connectivity.Mostly the signal strength is good arnd -93 dbm.I have full working Blue bars.But the problem is with the data rate and its connectivity.Most of the time i get the E signal but no upload or download activity.The data connection just dies.When opening chrome it is again regained.but after a few minutes it disconnects again.And the speed sucks too.
Also when the screen is off.It loses data conenction.
Any one with similar issues??Or a possible Fix???

Try reflashing the 4.2.2 radio.

I've made a app "WiFi Connection Manager" with fix Wi-Fi problem feature. Available on Google play.
If your phone is rooted, an enhanced fix mode can fix most of the Wi-Fi problem.

Im having the same problem with my Lenovo p770. I stopped Lenovo's battery app and so far seems to be ok. Sigh, didnt expect such petty problems.

Turning off the battery app made no difference. Any solutions?

Mobile Internet connection

Hi, sorry for disturbing, I have a weird connection problem and I am pretty sure it is not the internal antenna... When i use the phone for Internet, mail etc etc.... Everything goes fine it uses a 4G connexion and I almost never have a problem, I do have a problem Sometimes when I am not in a 4G covered area... Than i have to change the network modus to wcdma /gsm automatic because if I leave it on lte /wcdma /gsm the phone is jumping all the time between hspda /h/edge gprs... And this goes fast like that that connection fail... This problem stops when i change modus than I get a stable 3g connection.... A little bit disturbing but Okay..... The biggest problem is that I m always connected with my messenger services like for example WhatsApp.... When i have the phone in my hand no problem at all.... But when he stays on the table or in my pocket it is kinda weird.... Sometimes I don't recieve my messages and than suddenly when I pick up my phone I get like ten messages in once starting from like half hour before.... All this started like three weeks ago, network provider say there are no network problems, I didn't drop my phone or something... Internet connection is just acting very strange lately and this started before I updated to the official 4.4 rom and didn t change after...... I also have to tell that I don’t have problems at all with phone calls or texts messages..... It's just those two mobile Internet issues.... Since i m only good for using the phone and don't know nothing about the technical parts or something... I wanted to ask the question to all of you experts.... And wanted to ask for help and if possible a solution? I want to thank you in advance and hope you guys can help me soon.... Kind regards...

Try different modem perhaps?

Hi thanks for answering.... Tried everything.... Still same two connection problems..... Only thing I didn't do yet was a hard reset.... Could this problem be caused by an application or a bad uninstalled application? Thanks in advance

Hmmmmm, highly unlikely from my point of view, but however there could be some apps locked into 2G or 3G or 4G connection.
Try how clean system doing, if it's same, consider it a hardware problem which there is nothing we can do about it...

samsung s4
i am having network issues
wifi works good
2g works good
3g/4g doesnt work at all no signal if i select these networks
is it a modem issue or kernel issue

[Q] Note4 loosing data connection

Dear Friends,
has some who owned note 4 faced a continuous loosing data connection?
I have been facing this issue for the passed one week till now, I have tried to format the device but the problem is still there, I have not done anything to the device.
I called my ISP and they said that there is no problem with your sim card.
please advise if anyone of you had similar issue.
thanks

I've just experienced this today on my 1 day old N910C, I'm on 4G and suddenly earlier today my 4G mobile data indicator disappeared but it still showing the usual signal bars. Tested browsing, no mobile data it said. Tried putting it to Airplane mode then back to normal, didn't bring mobile data back. Rebooted it, then it's working again.

Not yet to see this problem but my friend's Note 4 had this problem. In the end he brought it to the service center and they replace the mainboard. Still wait and see if it fixes the problem.

it happened me before on other samsung devices too. generally an update fixes it but could be hardware problem too.

Hopefully its software related ive seen a slew of note 4s have this issue both variants included.. its annoying to say the least

Hi, I just got my phone, may i know whether you guys have resolved the issues?? i need to turn the flight mode on and off a few times to get the data connection back online

I sent back to Samsung services center, it seems that they said they reprogram the software. Will observe and see how it goes.

Mines all good now few updates and new provider all good ?

Hi guys, I've experienced the same issue, the mobile data connection suddenly drops (H+ icon doesn't disappear but the download arrow is off, meaning that there's no inbound traffic) and the only way to have the connection back is to to disable mobile data and than reactivate it. I've updated my phone, I even tried to install firmwares of other countries (different csc) and to change carrier but I haven't solved the problem (same situation on my friend's N4).

Hi
i had a problem with wifi. weak or no connection.
100% solution for my note:
go to settings=>location=>use GPS ONLY.
perhaps it solves also your problem...

Hello all! Just faced the same problem! Losing internet connection. Did anyone find a solution?

Note 4
Yes this is BS. If I go to a place with no data service, then travel back to a place with data service, I have to first disable then re-enable the "Mobile Data" toggle in the settings. It's such BS that this is happening. My note 3 NEVER has this problem. Starting to dislike Samsung's buggy releases.

Same issues..
