I'm using AOKP ICS 4.0.4, fresh install after full wipe.
Phone was charging over night, wifi and bluetooth disabled. When waking up from standby, I no longer had service. -105dB signal strength and no provider found. Bluetooth, GPS and Wifi did still work, but no mobile connection.
Powersafe mode was active and configured to switch to 2G only. Deep sleep mode was active, since Wifi and bluetooth had been disabled.
A reboot did solve the problem temporarily, but the problem shouldn't have occurred in the first place.
I never had an issue like this with any of the previous roms (all 2.2 / 2.3), although non of them had working deep sleep mode, so it might be related to it.
I'm living at the edge of HDSPA reception, so the phone will frequently switch between HDSPA, 2G and no net at all, like every time someone using the same provider walks by. It might have lost connection to provider while in standby and probably got stuck when waking up.

Hello. I'm sure that this must have been discussed but I cannot find the answer using search. As is surely normal, I use WiFi within the home and GPRS when there is no WiFi available. If WiFi is connected and I go out for a short while, then when I get back in a WiFi area, the WiFi is still connected. However, if I go away for a long time, and GPRS is used for perhaps a regular weather update, then the WiFi disconnects and has to be manually reconnected upon return to home. This leads to GPRS being used in a WiFi area unnecessarily if you forget to re-connect WiFi. Is there a WiFi connection timeout value or any other setting that can be changed? My old TyTN II did not have this problem. Thanks.
Try this CAB
It disable disconnecting WiFi when phone is in sleep mode and with this phone automaticly connects to WiFi when Leo will be in range.
Thanks Franq_23_pl. I think that the CAB just stops WiFi disconnecting when the device is in sleep mode. That will just drain the battery, surely? My old TyTN used to disable WiFi when in sleep mode, but as soon as you switched it on again, WiFi would be enabled and it would connect if in range. The problem with my HD2/Leo is that if I am away from my WiFi for some considerable time (ie, most of the day), then when I get back home and switch the device on, WiFi is disabled, and I have to manually toggle in on. So my question is..... What are the circumstances that cause WiFi to disable itself, and Is there some way of stopping it happening?
OIC now. I think you having some battery saving app and this app turning off WiFi when iz not used. What apps or registry mods you have installed on Leo?
You have the same behavior after hard reset?
My Leo don't disable WiFi. When i go outside (for ex to work) and back after few hours my Leo connecting to my home wireless network automaticly.
I remember, that i had the same problem like you and it was caused by app, which had duty to save battery.
I upgraded to another phone, but the DX is still receiving cell signal (probably roaming), is there a way to permanently turn off the radio other than using airplane mode?
Also, the Wifi currently have a very poor connectivity with my school's 802.1x network (takes multiple tries to connect/randomly disconnect even with good signal), is there a way to improve/fix this? It worked very well at my home wifi network.
I've had my Nexus for about a week now and noticed two strange issues with the WIFI connection.
1. I can connect to WIFI successfully at home but as soon as I go out and it switches to the 2G network and then later go back inside the WIFI doesn't auto connect it will stay on 2G, I have to disable and enable WIFI to connect to my home WIFI, is there a way round this or is it a bug?
2. Whenever I'm out an about and the phone detects a WIFI network even if its not configured to connect to the WIFI network the phone seems to disable 2G Data connection and continually notifies me of a WIFI network being in range and wanting to configure it, is there anyway of disabling this behavior and allowing the 2G Data connection to be active when no configured WIFI network are in range?
Any help would be much appreciated.
Thanks

Really can't help you much on the settings as I don't quite have my N4 but you should always turn wifi off when you're not using it. You will get much better battery and you wont have problem with #2. Sorry I couldn't really help much.

I have the same issue number 1. I find the battery is getting used quickly and the wifi will not connect. if i disable then enable, it quickly connects to the known wifi signal. I can see a different battery decay slope if I let this problem persist for a few hours, it then reverts to its usual slope once wifi is restarted. This problem usually only occurs once a day on average. I hope someone knows how to solve this issue.

Hi,
I have the strangest behavior with my wifi, the phone keeps connecting and disconnecting between 4G and WiFi every few seconds when i'm at home. This drains my battery in couple of hours and I can't do anything unless i turn off WiFi. I have smooth transition between 4G and Wifi enabled in settings (i've tried disabling it, all it did was to speed up connect and disconnect between 4G and wifi) Anyone else experiencing this strange behaviour with WiFi and 4g?
I have the same behavior. You need to disable "Smart network switch" under the advanced Wi-Fi settings. I have not found a fix that will allow leaving this feature enabled.
I disabled the "smart network switch" and my phone still refuses to connect to known networks that are well within signal range. It may be staying connected better once connected but I have my wifi sleep with the screen so when I wake it up, the wifi should re-connect. Not working well at all. This 5.0 update sucks, you'd think that since Verizon takes forever to get updates to flagship phones that at least they'd be well tested and stable, NOT!
Hi all, I want to present a scenario in which 3G data and wifi both are turned on at the same time. Android gives priority to wifi connection and uses it. In wifi "advanced settings":
1. Network notification is TURNED OFF
2. Keep Wifi on during sleep is set to ALWAYS.
Now suppose the Wifi signal is no more available maybe because of a power failure at the Router's end, Android switches over to "Data" connection. In this case, will the android continously search for the lost wifi signal and hence consumes a significant amount of battery power?
Thanks in advance
