I would like my gtablet to remain able to establish ssh connections
after the display turns off.
It appears even if I set the wifi preference to never go to sleep, once
the display turns off I cannot either ping or ssh into my gtablet?
So, I wonder if there is a way to do this.
(By the way, I assume that the wifi has power saving implemented
so just sitting around will actually not use much battery.)
I've noticed that when the screen goes off, adb even loses the tablet until you turn the screen back on. But I am having the same issues with Wifi, and setting it to never sleep in addition to installing a keep alive app doesn't seem to do much good. When the screen goes off for a couple of minutes, all connections seem to be lost.
It would be nice if there was some sort of solution to this.
yes, I can't get wifi to stay on. Basically, I want the tablet to stay
on but the screen to blank.
This is more important now that I have rsync installed and could
do automated data transfers or backups at scheduled times.
I am running Vegan 5.1.1 and am wondering this too, is it a vegan problem or gtab? Is there a dev that can make a kernal to stop this?
I am on a TnT ROM using Clemsyn's kernel, and I get the same problem, so it might be a device issue.
I'm trying out an app called Wifi Fixer -- free from the Marketplace (though I'll get the .99 cent donate version if this works). I left the tab display off and untouched for about 10 minutes just now, and wifi was still connected when I turned it back on. I'll let it sit for about 1/2 hour and see if it still works. If so, we might have a winner
In TNT (Lite), try Settings -- wireless -- Wi-Fi Settings -- Advanced Settings -- Wi-Fi Sleep Policy
wifi sleep policy is set so -- supposedly -- wifi never sleeps, but that did
not work for me (wifi was shut down when tablet goes to sleep - I wonder
what controls that - I would want display and system to have separate
sleep control ...)
But I found an app in market, wifi keepalive that seems to be working.
My tablet just turned off the display and I can still ssh, ping and rsync
successfully.
Maybe that is the solution.
I wonder how much power this will draw?
(I have a nokia n810 "mini-tablet" and even with wifi on (power saving
mode enabled) battery consumption is pretty minimal if wifi is not
actually in use. Does android use power saving mode in wifi?)
Well, I already had it set to never sleep. The Wifi Fixer seems to work though -- I let it sit for about 1/2 hour, and when I flipped it back on, the wifi was still connected.
Edit: Nevermind, that didn't work either. Sucks, I love this tablet, but if it's a dead fish when the screen is off for a few minutes, it's lost a good deal of usefulness to me.

That was the one I was using initially, but while it wouldn't drop the wifi connection upon turning off the screen, it would eventually drop it -- when I woke the tab back up, I'd have the wifi lost icon for a few seconds.

yep, it looks like that happened here too ... maybe some other
app is resetting this; it lost my connection after a radiotime
app was playing for about half an hour with screen off
I hear that ubuntu might run on this - it would be great to
have a **real** operating system to fiddle with
I am running Liquid Smooth 3.2 for months now. I format it regularly just to get a new sense of speed after downloading junk i shouldnt have to begin with. Recently i have been formating to fix my WiFi issue. It seems like when i connect wifi (turn it on) it simply doesnt connect (it doesnt turn from grey to white or blue) it just stays grey. WHen i look at the list of wifi available it says its connected but i receive no data. After a while it seems to syncronize and the wifi works. I used to think if i turn on 4g and wifi together it seems to speed it up. All speculation, the only fact is WiFi isnt working upon engaging it. Reboot fixes it untill i turn wifi off (or it the AP goes unavailable for extended period of time, it doesnt seem associated with turning it off and on.)
Any suggestions? I have tried backdating to .09 radio. It doesnt seem to fix it.
Hi All,
I experience a Bluetooth trouble for some weeks: by the past I kept BT always active as it connected automatically upon entering in my cars. I was alerted because I no longer saw the “Connected …” message on the dashboard. I discovered that now, when I activate BT, it starts normally but it stops if it doesn't find any device to connect in the following 2 minutes. I have tried everything I know, even installing some software starting BT and keeping active when the phone is plugged. Nothing to do, it is always the same thing. Fortunately if it finds a device to connect it stays active as long as it is connected.
I have to say that I don't use any battery saver, I don't use the Android option "Energy saving" and I don't use any system program that could be linked to Bluetooth management.
Can anyone help me on this to recover a standard comportment?
BR.
Daniel.
Ok, now I am having a couple of issues that are starting to bug me.
I connect my Z2 to a Mercedes Benz system (2014). The Bluetooth Connected blue icon keeps popping on and off. That doesn't really bother me, except that (a) Bluetooth crashes if I am connected over a certain amount of time and (b) I get at least one dropout where it will lose the connection to the system and then come back after about 10 seconds. Unnerving when you're on the phone.
Secondly, my WiFi has been intermittent at work today for no good reason. I'm right under the AP but it is having a problem connecting.
Anyone else experiencing these things?
How the bug works:
So I can be connected to my wifi, surfing the web, on youtube or anything else. But all of a sudden my phone disconnects me from my wifi. Now, this in itself is quite frustrating as usually I'm in the middle of doing (please note though that it has also happened plentiful times whilst I haven't been using it too) something and it takes a few minutes to realise that it had happened. But unfortunately, this isn't the end of it. When I go to reconnect to my wifi I press it and nothing happens. Literally nothing. No animation, no sound and it never connects it just refuses to. So then the next logical solution is to turn off my wifi and turn it back on so it re-connects. And it works it connects to my wifi. But about 30 seconds later it will disconnect again. Sometimes though when it disconnects, it does state that an authentication error has occurred. But back to the bug. Then when pressing it nothing happens again. So I have to turn off my wifi and turn it back on usually 4-5 times before it finally stays connected.
This bug usually happens twice a day and is very frustrating, so again any help would be amazing!!
What I have tried:
- Turning off the device does not work. The bug is still present
- Using WPS to connect works sometimes but is very hit and miss
- setting my wifi to stay on whilst the device is sleeping
- wiping all network settings
- wiping all wifi settings back to default (in the router that is)
- Factory Resetting
Some other things to note:
This bug has not always been present. It has only started to occur within the past two months and I have had this device for 2 years now. I have not changed any wifi or device settings for it to happen. And it just started one day.
My dad's S6's wifi is completely dead.. I click the toggle switch and no networks show up.
Also tried clearing cache, resetting network settings, and even factory reset.
I think the WIFI antenna is dead/dying?
Just happened out of the blue as well..
Perhaps a root and new rom will fix?
