Data switching in G1

Hi. I've bought my first Android device, a HTC G1 Dream. I've gained root access, installed the last Cyanogen release (with Android 1.6), RA-1.2.3.
What I've noticed is a strange behavior, quite different from the one I had with my BlackBerry Bold.
When I'm home I enable wifi, to save some datas from my (limited) contract. It works and I've set not to disable wifi when in standby. It works. But as soon as I go out (and the wifi coverage finishes), it doesn't re-enable UMTS data until I awake it from the standby manually.
It's quite annoying...is there a way to change this kind of behavior?
Thank you very much!

Is it still connected to EDGE or GPRS? If this is the case it is a PowerSaving feature, if it's totally lost connection with the net then you have a problem I guess...

When I connect via Wifi, it disconnects from edge, gprs or umts. And doesn't reconnect when the wifi coverage ends (unless I "re-awake" the phone,pushing the menu button)

from what i read your saying thats while its sleeping its not connecting to your data services when your leaving wifi coverage, so my question is: do you not see the data icon when you wake up the phone but after waking it it comes on or are u assuming that its not on?

Yes, I cannot see the icon as soon as I wake up it. Then, in some seconds, it reconnects. More, I can see it's not just a "icon" issue because my K9-mail stops collecting my mailboxes when that situation happen.

[Q] Am I the only one experiencing these 2 issues in regards to WiFi

Having had my LG 2x for a bout a week now I have come to find that it suffers from 2 issues I find annoying, and bordering to simply slack in making from the side of LG. Issues such as those should simply NOT excist on a phone such as this one :/
1:
I use my WiFi at home but sometimes I see that I am NOT connected to it and go into WiFi settings only to find that it says my network is "Disabled". How has it become disables, and why is the questions I would like to ask. I would like to know what causes the phone to think that.
Again my former phone was an HTC Desire and it used and connected to my WIFi network without any problems or issues leading me to suspet that this error is simply caused by LG either by fault in the hardware or a bad software that they released their phone with.....
2:
Sometimes if WiFi is actually enabled I will not be allowed to toggle on regular mobile data. The phone replies with the message "WiFi Connection open, cant open Mobile data" or something of that sort. I have gotten that message a few times over the last week and it comes regardless of whether or not my phone is actually connected to a WiFi Network or not.
Which basiclaly means that I cant use mobile data without first disabling my WiFi, reenabling mobile data and then reenable WiFi and then it works again.... for the time being.
Sometimes the phone also just disables mobile data on its own meaning I cant get any data connection unless I do the procedure above again. Its simply annoying and something that just shouldnt happen on a phone of this caliber . And with that comment I mean both the issues, because its simply not supposed to hapen for a phone in this price range or of this caliber.
All in all it seems more like LG cutting corners to be the first ones to release a Tegra2 phone. Cutting corners meaning that we have to content with a phone full of errors and bugs

I am having the same Wifi issue, it disconnects for no reason.
Hopefully this will get fixed soon in a 2.3 update. This minor wifi bug does not irritate me that much, the phone otherwise is a beast.

I had the same problem. It was caused by the wireless security/encryption method used in my router. I changed it from WPA2 Personal to WPA2 Personal Mixed, and now the router no longer disconnects my phone from the Wi-Fi. So try that.
You could disable the router wireless security entirely just to test ...

Well, I never leave the 3G connection on if I dont use it, so I can't answer you there. But Wi-Fi have greater priority than 3G. This means that enabling the 3G connection when having the Wi-Fi on and connected does not do anything. The 3G connection will only connect when the Wi-Fi is disabled.
It was the same on my former HTC Desire.

Sorry if I am a bit blunt. But that security setting has worked up till the point where I got my LG 2x, it works between all my laptops, on my SE G900, and worked flawlessly when I had my Desire, ie then its LG's issue and they just need to fix it.
IMO I can live with it getting tits up once in a while, AS LONG as it is fixed when LG releases Gingerbread. LG should however be asked why the phone "disables" the connection.
But I just checked my AP and its present setting is WPA2/WPA Mixed Mode. And the other "options" I have is: WPA2 Personal, WPA Personal, WPA2/WPA Enterprise Mixed Mode, WPA2 Enterprise, WPA Enterprise, WEP, RADIUS and Disabled.

I think you misunderstood me there . WiFi is turned on, but NOT connected, ie it should default to 3G data. But if I click my icon to turn on 3G data I just get told that it can't because WiFi is active, which it isn't since its not connected to any Access Point.
When I leaves my apartment I leave my Wifi on, and the second I leave the reception area of my AP the phone automatically switch to 3G data and back to WiFi again when I return. And thus I tend to keep both "on" to allow that seamless transition. In effect I could technically just disable my WiFi and stay on 3G considering I have a 25 Gig limit, but using my WiFi at home is just so much faster

I have the "disabled" status occasionally on my phone. It's triggered by 3 unsuccessful login attempts to the AP. This can happen if you're on the very edge of WiFi range but not sure that applies in your situation.

Well it might be that error that I am falling for then, but its just strange that the LG stalls, while my HTC Desire didn't seem to care and just grabbed the connection.
I wonder if there is some way to change it to try like 100 times or just completely ignore the limit and keep trying till it gets through.

I just had the "Disabled" issue again while sitting at home and being what 2 feet from the APN, so its certainly NOT a range issue :/
Hopefully this gets fixed with Gingerbread or I might go looking for another phone.

i have this problem with my folio and my 2x....
disabling wifi and enabling wifi helps.
for my folio i can say its a screen sleep issue(something messing with wifi as well,no solution afaik).
so if im downloading stuff and the screen goes to sleep my download stopps.
sometimes it resumes after wakeup, and wifi works fine, sometimes not.
for my folio the solution was to use the dockingstation, couse then it changes to a clock, and the screen doesnt time out.
today at work i was downloading stuff over my 2x, and expierienced the same strange behavior.
dont really know if its related(both tegra2 devices so it could be), but the occurance is too similar.

Well disabling security will do me no good at all considering I dont want to leave my wireless network sitting open like leaving my house unlocked.
So no thats not really an option... sorry :/

Of course not, but have to tried? My earlier, and now, is that your problem may be caused by the security on your router. It was a problem I experienced.

I have not tried yet. Because if i turn off the security and my phone then stays connected then its not a solution >_<. Its still an issue that the phone is causing.
BUT that said I would need to leave the security off my wireless for at least a week in order to really get any reliable data on whether or not its the security setting in the router that causes the issue (But I think rather not when all other phones has no problem with it). And sorry to say this, but im not leaving my internet open for a week to determine whether or not disabling my security makes my phone able to stay connected.
My HTC Desire could get connected and never disabled WiFi on it self. And the LG 2x does it. Ergo it must be an issue on the phone when it is the only phone in and around me that causes that issue.

have you tried changing the pw to a shorter one? in the shop where i work, some devices have problems with long passwords. some just connect to the router with the 10 char pw. connecting to the other router(20char pw) is sometimes a problem. the two routers are the same modell.
EDIT just tried it with the optimus, both router work, so this wont be an solution. sorry

[Q] Wifi problems with multiple router networks

I seem to be having pretty severe wifi issues on networks that are composed of a large number of routers (i.e. campus/business networks) where going between routers will result in the phone believing it is connected, but not being able to send/receive data. This is evidenced both by the lack of notifications/apps working, as well as the wifi icon in the quick toggle panel being orange (which indicates no data being sent/recieved, I believe) despite having full signal. This means that without any external indication that anything is wrong, my phone essentially does not work anymore until I turn the wifi off and back on. Previous phones (galaxy nexus, droid) as well as computers did not have this issue on the same network.
Has anyone else noticed this problem, and if so, found any way to get around it other than remembering to reset the wifi power every time you move between areas?

It sounds like there are multiple WAPs all using the same SSID, and Android is not requesting a new IP address when it disconnects from one WAP and connects to another. You could probably work around the issue using Tasker, and have it toggle Wifi off and on again any time Wifi is disconnected. I you go that route I would recommend using the trial version available from the developer's site, or one of the many similar apps that are available in the Play Store for free.
There may be something more to this though. Hopefully someone else has another idea.

I'm having the same issues both out in public and at my home. This issue didn't seem to exist prior to 4.4 update. Now I'm constantly having to toggle my WiFi on and off or toggle airplane mode and also hitting the symbol down at the bottom left on my phone and on my router at the same time. If someone has any information to correct this would be great. Like I said I never had this problem prior to 4.4.

Thanks for the suggestion! One question though: does the wifi actually "disconnect" when there is a handover between two routers of the same network? Is a handover while constantly connected something tasker could detect?

As far as I know, Android doesn't "roam" seamlessly from one AP to another even when the SSIDs are the same. I'm pretty sure Tasker would see this as Wifi being disconnected (albeit briefly). You could then tell Tasker to turn off Wifi for 5 seconds and then turn it back on again.

I finally got around to making a tasker script to do this, and tried it out for a few days, but unfortunately it does not seem to detect the changing between the different routers on my institute network as having the wifi disconnected, and thus doesn't solve the issue. It was a good idea to try though!
I've cross-posted the issue at the link below in hope motorola will see this, but if anyone knows a better way to report this, please let me know.

[Q] WiFi Poor Connection Avoidance

Hello,
Anyone else having an issue with their Nexus 6 device where if it detects a poor WiFi network, it will disconnect from it but in this state, it does not connect to your carrier's 4G/LTE connection? I know this used to be a feature you can enable or disable (Settings-> WiFi -> Advanced -> Avoid poor connections) but looks like this option has been removed from Android lollipop and instead is just enabled by default with no way to control it.
I noticed this when I walked outside my house and didn't have any data connection. When I went to my WiFi network lists it said "Temporarily Avoiding due to poor connection". It did not automatically connect to my 4g/LTE network, I even stood there for a few minutes to see if it eventually would. The only way to enable data was to turn off WiFi. As soon as I did that, it established connection with my carrier.
Screenshot attached.
Thanks!

many have this issue. There is a thread under the nexus5 section and this is the link to the google issue page https://code.google.com/p/android/issues/detail?id=81843

adaptive wifi

I have it enabled and it says it auto turns off WiFi and back on when near used wifi locations but it doesn't do that at all. Does it simplyeave WiFi on but low energy?

Screenshot l

Yeah it works.
How do you know it doesn't do it? Cellular phones hand off betwixt cellular and wifi all the time.
When and how often it does is based on some under the hood shenanigans that we dont know about.

I don't think it's supposed to turn off. What that phrase means is that it will connect to WiFi when it's near a saved access point and will use mobile data when none are nearby, but WiFi will still remain on.
What adaptive WiFi does is it will use mobile data even if it's connected to a WiFi access point if the WiFi signal is bad.

I'm not sure what adaptive wifi supposed to do, I have it off and it switches between wifi and cell as it should. Is it switching in the middle of data transfer or something? Because right now I probably drop connection if move outside wifi range and will be on cell tower on the next redial. But to tell truth I never tested it.

So basically it's a gimmick, because Wifi as it is, will auto-connect to previously connected networks as long as you had wifi on. If i'm interpreting the screenshot properly the feature "turns on" wifi, therefore, it must be able to turn it off? I've even manually turned it off to see if it will turn itself back on when i get back home and nothing either.
No documentation on Samsung's site as far as i can find

Basically if you're connected to WiFi but have crappy signal like .2 kbps, it will start using your mobile data even if you're still connected to that WiFi. With adaptive WiFi turned off, it will keep using the crappy WiFi connection until you manually turn WiFi off or manually disconnect from the crappy network. Pretty much the reverse of WiFi calling (use WiFi if phone signal is crappy). Note the exceptions sentence at the bottom, it will not use mobile data even if the WiFi has a crappy signal if the crappy WiFi is exempted.
The "turn on" statement is correct, it will automatically turn on and connect to WiFi when it's in range of "trusted" access points (similar to "trusted devices" and "trusted places") but there is no automatic "turn off", at least, it hasn't done that while I've been using it.

OK i see what you are saying
wifi does not PHYSICALLY TURN OFF. wifi is still connected--the phone will auto switch to the stronger of the two. it won't turn the on screen "switch" off if that is what you are looking for.
its not a gimmick. it works if you are in an area with robust wifi and/or cellular. its supposed to work "in the background" so you don't know its going on.
google fi kinda does this. since google fi uses tmobile and sprint, the phone auto switches between the two carriers depending on which is stronger at the time. i've seen this happen by monitoring an app.

Not a gimmick at all. I work at a hospital that has wireless routers throughout that all piggy back the same access point. I see Adaptive wifi in action all day. Keeps me from losing my connectivity from my work portal.

don't think I want to have this on: I have limit on my cell data, let's say I start downloading something large, let's say 5- 10 GB movie from Amazon on wifi, then I go to my upstairs bedroom, wifi gets weaker, so it switches itself to stronger cell tower and eats my whole month data allotment in one evening, before I even notice? And all I had to do is keep the phone downstairs, next to the router to avoid it. Or am I missing something?

Exactly what happens to me when I leave home. My phone (old Note 7) will stay connected to my home network but won't be able to pull down any data from the net. It has to be manually turned off.

Any 3rd party apps you can recommend that would do what i am looking for?

so an update. It work exactly how it says it would. I had to drive 7 miles out, but wifi automatically turned off, even with scanning off, once i got home it turned back on.

I like it. It works great for me.

Ah, that's the thing. I noticed my WiFi would automatically turn off sometimes and sometimes not, and I couldn't reproduce it reliably. It's most likely either distance or time you have to be away from the "trusted" access point.
Congrats, now you can forget about toggling WiFi forever!

I think this setting has been screwing with my wifi related Tasker profiles. Suspect it really does turn wifi off.

I used to switch my wifi off manually when leaving the house.
All this #[email protected]\%! public wifi, blocking my internet because asking to log in....
Any shop or restaurant where you walk in does it.
And you do not know it, till you search the web and see that there is no internet at all till you switch your wifi off or log in to the shops fishing routers.
Adaptive wifi is a must have and a great improvement.
E.g. walk in a MacDonald's with adaptive switched on or off, you will see it is mother's little helper.
You need to have enough data from your provider of course.
