WiFi connection problem

Hi to all, does anyone have problem WiFi connection its stops working then, the icon shows full bars but if I'm trying to use its using the 4g connection. Like both icons are on and its using the 4g connection, sorry I don't know how else to explain.

The thing is it doesn't turn off the 4g radio once u connect to the wifi it shows both of them connected and when I try to use the speedtest app its testing the 4g connection then changes to wifi
Sent from my LG-P999 using XDA App
I saw that this morning. It just took a while for it to actually switch over to wifi and I don't think the 4g icon ever went away.
I'm trying my best not to use wifi because I'm testing T-Mobile's service to see if it works for me.

I'm having a similar problem. I have a terrible T-Mobile signal in my house so I always have wi-fi enabled. I've noticed a couple of times that my phone tries to use the mobile data instead of the wi-fi data even though I have no mobile signal and full bars on the wi-fi. I have to either go to airplane mode, then re-enable the wi-fi, or un-tic the "use mobile data" box in the wireless settings, and then it will switch to wi-fi and it works fine. I've had the phone for two days and this has happened twice.
One other thing I've noticed is even when I have a good signal, MMS is reluctant to send over the mobile network. If I reboot my phone and then send the message it sends right away.
It also takes a while for it to switch to wifi for me as well. Once it's on, it's on though. I noticed that to enable it quicker, turn it on and go into Wifi settings where you see all the available networks. It appears to connect instantly from that screen.
Yes this issue is starting to get real annoying. I powered on this morning and both wifi and 2g connected. 2g wouldn't drop until I toggled the data connection

Any advice on improving WI-FI calling.

Any advice on improving WI-FI calling.
I get no signal inside my house.
No one is online and all computer are off.
Stock Gingerbread Tom.
You get no wifi signal or the wifi calling will not connect?

WI-FI connects and every thing
WI-FI related works great except WI-FI calling. I have the router in the middle of house. The call connection is fine at first then it acts like when a cordless phones go out of range static and echo.

I use WiFi calling all day without this issue. You might try telling your router to use a different channel, and/or looking for sources of interference.
That sounds more like internet connection quality to me.
I would try making sure nobody is running torrents or other high bandwidth stuff at the same time.
I had no issues with WIFI Calling on CM7. I recently switched back to the stock rom and have had jitter issues and poor sound quality. Hope this helps.

+1.. get the free wifi analyzer app.. then switch your router to the channel with the least interference.
I try that on my next day off.

What version is your wifi calling app?
Hope this helps.
Sent from my LG-P999 using XDA Premium App
In the WiFi Calling app settings, check under Connection Preferences to be sure you have WiFi preferred for calling selected, just in case something changed it. Also, in the setting area, maybe under advanced, there is a menu option for log errors. That might help point to the problem and a solution.

I had the same problem when I was on stock rom. Once I updated the baseband and flashed a custom rom, I dont have that problem anymore.

[Q] WIFI Question

The only network I connect to is my home WIFI... here come's the stupid question...
when I leave the range of my home network it will switch to 4G
but... will it switch back to my home network when i am in range
in essence, does it prioritize wifi over a 4g connection if a profile exists?
i ask because i had downloaded VZW auto wifi on... seems like it might just be bloat
anyway, thanks all
I'm fairly certain all Android phones "prioritize" Wi-Fi over mobile data. If you leave LTE enabled then turn on Wi-Fi while home, you can see this yourself.

Yes. If you leave your wifi on on your phone and at home, when you get back home it will auto connect to the wifi cause it scans for available points every so often

[Q] Wi-Fi data transfer

I want to know if you can transfer data to/from Android devices through Wi-Fi without a router?
Here's the story:
There is a a SGS2 from which I have to take lots of data and I don't have Wi-Fi network nor can I use Wi-Fi Direct (coz NS doesn't support it) and bluetooth wil be painfully slow. Is there any way out like making an FTP server or something like that?
I don't want to use mobile data.
It's just too puzzling...
Use public wifi hotspot and cloud server like DropBox ?
Or: USB connection to PC?

No PC available and no mobile data to be used...I can't be using mobile data for files sizing up to hundreds of MBs...
Seems difficult but i have a feeling there is a solution...

There's several public wi fi hot spots in Mumbai. 2 near ft. Mumbai. Barista coffee. Why can't you use them to back up your data to the cloud and transfer to the other device?

The thing is that I don't want mobile data to be involved anywhere.
I was just wondering if this can be done somehow by making one phone a server of some kind and the other a client and connect them directly.
I agree there are some other ways like you and other users have mentioned but i just want to try and use it this way.
If it's not possible then I'll just use the old fashioned way.

Wifi does not involve mobile data. You can avoid accidental charges by toggling mobile data off.

My wifi keeps disconnecting and reconnecting

Ever since my device got bricked and flashed the the original firmware, my connection on wifi keeps disconnecting and reconnects even though im like 10 feet away from my router. This bothers me because I cant play online games. Is there anyway to fix this?
Sent from my SCH-I800 using xda app-developers app
I suggest you turn off your router (or also disconnect the cord) for 30 seconds, turn off your WiFi on your phone, then plug it back in and turn on your WiFi again and check. Otherwise it might be a phone problem.
I'll give it a try
...When im connected to other wifi network this doesnt happen.

You should consider buying a new Wireless Router which is more powerful. As your statement, that this issue doesn't happen in other WiFi network, try to check the speed of your internet, traffic, etc.
My other devices works fine

try to forget the network, restart your phone and connect again.

So the issue must be the communication between your phone and the device. Try to restart the phone, or remove your wifi, and then enable it again.
try this
go to settings> WiFi > advance > keep WiFi on during sleep > select always on
I tried, the problem is still there

problem solved and a question-why does unstable wifi mess with usb?
My phone kept getting disconnected from my computer. This was apparently happening because my wifi was unstable. Not sure why the phone disconnected, I was connected via usb. The wifi was unstable because I was using a proxy. When I use my comcast connection straight through the problems go away. If someone can explain why an unstable wifi can screw up a usb connection I'd be grateful. Windoze issues?
