Cell network disconnects when Wifi network is connected - Galaxy S 4 Q&A, Help & Troubleshooting

I got this weird problem when I connect to any wifi network, my cell network will disconnect briefly for about 10 seconds ( with a stop sign ), then it will connect back.
Isit only me that is facing this problem? I tried several stock roms and kernel but it is still the same.

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.

interesting WiFi problem?

Well I have ICS/CM9 freshly installed on my MB525 and TP-Link WR740N at home. When I set the wireless to 11bgn mode I can connect to it but just for a few seconds then it disconnects automatically. When I set it to wireless 11bg mode there are no problems connecting and browsing. Other thing is that only my phone fails to connect when is 11bgn, my brother's Samsung has no problems ... I installed the latest firmware for my router.
P.S. I have WiFi problems only with my router, with others there is no such problem

Wifi problems on certain networds (CM11 Android 4.4)

I got a wifi problem on my defy with CM11 Android 4.4.
At home I can connect to my routers wifi perfect.
But in school I can't connect to any network. The school has two available networks, one with a password and one without password that authorizes you through the browser.
I'm unable to connect to either of these. They have full wifi signal, but when I click connect they immediately drop to 1 "bar" and disconnect. After the disconnect I got full wifi signal again, but when I connect to drops to zero immediately.
Any idea on how to fix this? Maybe some of the network drivers having problems with networks with a lot of users?

N4 wifi problem, help please

My N4 is no longer able to detect my home network. It detects my neighbor's network and several other networks, although it cannot connect to any other network. When I try to connect to a detected network, it just says "Saved". My home network is working fine and several other devices in the home are connected to it. In fact, my wife's N4 is still connecting with no issues. I have tried rebooting the phone, rebooting the router, telling the phone to forget the network, changing the channel on the router, no success. Running version 4.4.4.
Any thoughts on what might be wrong or ideas for a fix?
Thanks,
b
You haven't inadvertently switched the WiFi frequency from automatic to 5GHz have you? It's just that I had a similar problem and that's what had happened.
