[Q] Disconnect from weak wifi signal without disabling radio? - Droid X General

First, I apologize if this question has been covered before. I've searched extensively but sometimes I miss the obvious.
I'm trying to find a way to have my phone automatically disconnect itself from my router when the signal is weak without turning off the wifi radio. I've found apps that automatically turn off the radio when the signal is weak, then intermittently turn it back on to see if the signal has improved, but this isn't exactly what I'm looking for.
There are certain areas in my house (and backyard) where my phone still sees the router, but the signal is so poor the 3G is actually (significantly) faster. But Android doesn't switch you over to 3G until the wifi signal is actually lost.
I know if you leave the range of your router but leave the radio on, the 3G takes over automatically and the wifi radio runs in the background, silently searching for a connection. So is there any way to use this functionality to tell your phone to disconnect the wifi automatically if the signal is incredibly weak (but still connected)?
My first thought was to set up a Tasker profile of some kind, but I haven't had any luck. Any suggestions?

Unfortunately connecting/disconnecting wifi using Tasker is not possible.

when I owed droid X I had the same issue, I flashed custom baseband and it helped

8525 freezes after loosing the weak WiFi signal several times

Hi all,
I'm facing a weird WiFi problem which seems to be different from the ones that have been discussed before and referenced in the FAQ.
Specifically, when I just turn the WiFi on, I can connect to the network (WPA2-TKIP secured), authenticate and browse Web sites etc. There are no problems with the proxy, unavailability of WAP2 in the drop-down box - within first minute or two after turning the WiFi on, everything works as expected.
Hovewer, the signal strength is unstable, and once the signal dies a couple of times, the 8525 freezes: the backlight instantly goes off even if the device is AC-powered, and the device stops responding to anything except Soft Reset.
It should also be mentioned that my WiFi is configured for best performance, not the battery saving mode.
I was suspecting it was a hardware problem, so I hooked up my 8525 to my notebook over WiFi at home, using WEP security. I was hoping that if it was for the broken WiFi hardware, I'd observe the same freezing effect. Still, the WiFi worked just normally. I must admit I didn't intentionally emulate the loss of signal (should test it as well), but with nominal signal strength there were no problems at all!
So does anyone have an idea what could be the reason of 8525 freezing after loosing the WiFi connection? I know there are issues when WiFi is left turned on in standby mode, but, as I've said, in my case the 8525 freezes even if it's on AC power and is being actively used. I've also noticed that sliding the 8525 to access the keyboard somehow increases the probability of freezing, especially when the device is on battery power.
My OS ROM is wm6premium.v2, perhaps there are known WiFi problems with this ROM? Also, the Phone is HardSPL'd and SIM/CID unlocked. Please help, as except for this weird WiFi problem, I'm totally satisfied with my 8525.

3G not turning off with WiFi

Randomly when I'm on WiFi, I'll see 3G not disappearing which means I'm using double radios. Any ideas why it doesn't deactivate? Most of the time it works, but sometimes I need to turn off/turn on WiFi to fix it.
Bump bump...
Some data is only accessible through your carrier signal, therefore you may notice 3g kick in while on wifi. It shouldn't happen all the time though like when just surfing the web. Does this happen in programs like browser while surfing?
How long are both on at the same time? I'm sure there's a few seconds of changeover time from one to the other. Also like XfooYen stated some things could require a carrier data signal, for example the A-GPS.

Disable Cell Signal

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.

WIFI Issues

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
Jon
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.

Wifi and 4G stuck together - how to fix this?

I know i'm not alone since i've seen this issue not only on my phone. When i'm at home my phone is mostly connected to wifi. My router is Linksys AC1900. Sometimes both the wifi and 4G icons appear together. when this happens my battery is draining like hell. a simple restart of the phone or the router is not a solution - i found that in order to make the 4G icon go away i need to first turn off the router so the phone is connected only to the mobile network, than i have to turn off both the data connection and wifi of the phone; than i need to go and clean the cache through the builtin recovery menu. the problem is that sometimes even performing all these things is not enough and the 4G icon won't go away. Download booster and Smart network switch are both turned off, but playing with them do not really affect the issue. also i tried connecting to both 2.4 or 5ghz wifi with no difference. i also tried setting a fixed IP address for my phone, but again this does not affect the issue. any ideas? i'm pretty certain that it's not a hardware issue since i've seen it happening to other people too. it's quite annoying since it's totally destroying the battery life of the phone and it seems that there's no real solution for this behavior.
What model number is your phone? Have you considered reflashing firmware / factory resetting the phone?
The model is 935f. I've tried reflashing with stock several times (the phone is not rooted) but after a while the problem comes back. This is the only issue I've had with this phone but it's quite annoying.
I've got the same issue. The only solution i've seen till now is to reflash with a custom rom.
Same
I have picked up the same type of issue. I did some snooping around and have found that if I have my mobile data on when in the streets and when I get home and I turn on my wifi, that if my wifi signal is very bad and my mobile data is on, then it would show both signals. It's as if the phone tries to get whatever data from both, since the wifi is so bad. I agree that it really chows the battery. The only fix I could get to work is to switch of the data and move closer to the wifi where it's the strongest. I will sit at the router for a minute or two, It then automatically removes the 4g sign and only works on wifi. If I stay where the wifi signal is bad and disable mobile, it stays there even though my data is off.
Did you do a factory reset and restore your phone to its original settings?
