[Q] Wifi won't reconnect - Verizon Samsung Galaxy S 4

Say I'm connected to my home wifi after I flash my phone. I'm connected and everything is great, I don't loose signal. Now I go to work, where I have the wifi profile saved in my phone. It wont connect automatically nor will it connect if i select it. This goes for all saved wireless profiles on my phone.
I've checked the tpyical settings under the wifi itself. (sleep/power settings)
I've tried different roms, all with clean/full whipe's prior to install.
CROM
Hyperdrive - seems to work but having issues with the rom itself performance wise.

Under wifi > Advance, make sure Always Allow Scanning is enable else it wouldn't know you are within the range of a network

[Q] CM7 WiFi settings

Hello All,
I'm using CM7 (2.3.3).
Where are the settings to have WiFi set to turn ON automatically when the tablet first starts up? Right now, WiFi is always off when the tablet starts up?
Thanks,
Paul
I'm having the same issue...
For me I simply go to settings > wireless & networks & enable wifi. From there I simply connect to the needed connection & it will connect automatically when it is within range. I've never had to do more than that as it will connect on its own even after a reboot.

[Q] Wifi issue in the Xperia X10

So I rooted and loaded the custom ROM on my Xperia X10 exactly following the instructions on the video found here : http://forum.xda-developers.com/showthread.php?t=1305945 (Installed the ROM specified in the OP of that thread)
It works well, except for one issue. The wifi doesn't connect automatically to my home network even when within range; one second it is connected and the next it disconnects and doesn't re-connect. I then have to go to Wireless settings and wait for it to connect, which might happen immediately or after I select Connect. Sometimes, it just goes through a Connecting-Disconnected loop. Any ideas?
I've already set the sleep policy to Never and forgotten the network and added it again.
Apologies if this was answered before; if it was, I'd really appreciate someone pointing out the solution to me.
Open build.prop in root/system, mount as r/w
Search for this line and change scan interval to 30 second (or fewer) :
Code:
wifi.supplicant_scan_interval=30
You're done :beer::thumbup:

From first impressions, that *looks* to have sorted the problem out. Much thanks :good:
Unfortunately, that hasn't solved the problem, even after setting the interval to 10.
The problem goes like this:
I'm within WIFI coverage area of my home wifi, and the first time I switch wifi on, it connects automatically. After sometime, it just disconnects without reason as I'm using my mobile without moving out of coverage area. Now the most irritating part is that it doesn't connect automatically again. I'll then have to go to my wifi settings, select my wifi network (which proves that it's still in range) and select connect again. This again doesn't work all the time, and sometimes it just goes through the scanning->connecting->disconnected cycle. wifi sleep policy is set to Never fwiw.
I want to know how to stop it from disconnecting randomly even when within range, and connect automatically when in range, as this is extremely infuriating to use now
Is this a known issue with the mod that I'm using? If so, is there any other mod that I can use?
PS - The wifi was alright in the original SE device before rooting.
I have had this happen too.
I'm using DoomKernel V6 [root] on GB 2.3
Wi-Fi is active in a Wi-Fi coverage area with a stable connection and good signal.
Screen times out and after some time the phone is used again and screen unlocked.
Wi-Fi does not attempt reconnect to Access Point.
Status shows Wi-Fi in a state of scanning.
Preferred SSID is shown as available with good signal., but not connected/connecting
Disable Wi-Fi and re-enable Wi-Fi
Connection is re-established.
I have an XPERIA S v4.0.4 in the same Wi-Fi coverage zone using the same SSID and it connects every time. Just unlock the screen and a couple of seconds the preferred SSID is connected/re-connected. Every time.
XPERIA X10i
I did at one stage have a timed Airplane mode app that would disable Telephony and 6 hours later re-enable Telephony.
I was on a GB v2.3 build with DoomKernel V6 and XS system apps and after Telephony had been disabled is was _not_ possible to establish a Wi-Fi connection without restarting the phone. Although some times you could 'jag' it and make a re-connection, but mostly, it would only say disconnected and no options would re-establish a Wi-Fi connection to the preferred AP even when it was seen as an available AP and good signal. Disable and enable Wi-Fi did nothing.
After numerous other ROM/Kernel installs over time, I'm now back on GB v2.3 and DoomKernel V6 [root] with XS system apps.
This time round I only have to disconnect/re-connect to establish a Wi-Fi connection. No more phone reboots required, even in airplane mode.
Many times the Wi-Fi connection does re-establish itself, it's just a nuisance when it doesn't do it every time and you have to disable/enable Wi-Fi to establish a connection.
What I've tried without success.
[X] Added a static ARP on the router
[X] I changed wifi.supplicant_scan_interval down to 50 from 120 no change after a couple of days.
[X] Changed advanced Wi-Fi timeout from AC power and screen-off
I'll check logcat next time and see if that gives any clues.
Thanks for the input
Now, can someone swoop in and tell the solution?
Anyone?
If no one has any idea, are there steps on how to install a new custom ROM instead of the existing one?

seems that your bootloader is locked because i saw on that thread that you talking about that you are on Zdzihu cm7 rom with his kernel for locked bootloaders ... so i recommend this one to you :
http://www.mediafire.com/download.php?zhdzap0cek4pkvh
by ThJap its totally fast and stable with no issues
http://forum.xda-developers.com/showthread.php?t=1193001
just download the zip file and put it on sd card then go to xrecovery :
1. Full wipe, Wipe dalvik cache, and wipe battery stats.
2. Flash the ThGo_v.XXX.zip package via xRecovery
then its done.

WiFi only reconnects after manually reconnect to network (logcat)

Hello,
Every known wifi network I walk into, I get an wifi connection failure and my phone does not get connected. After going to the wifi network settings and manually choose connect, there is no problem...
Also overnight, my connection get lost and when I wake up I have the same error. I have to do the same thing (manually connect to my known wifi network(s).) before I can use it...
Deleting the network and adding it again will not solve the issue. I have attached the logcat. I also have enabled extended wifi logging for the logcat.
At 16.21 I enabled wifi and it does not connect
At 16.50 I manually connect to the network
Does anybody know what's going on?
Thnx!
Another logcat during night. Somewhere I lose my wifi and my device won't reconnect.... I gave to manually choose reconnect on the known wifi.
I already deleted the data in data/misc/dhcp and data/misc/wifi and removed all the known networks and start adding them.
Already did a full wipe (factory) reset with no results..

Can I get my device to auto-connect to WiFi without internet?

Hi everyone,
I own a Nexus 5 and I am running stock firmware, Android 6.0 MRA58K, unrooted and bootloader locked. I use this device at work and frequently connect to a WiFi LAN that has no internet connection (by design -- I use it to talk to other devices on the network). In older software versions (I believe back in the KitKat days if I recall), I could simply turn on the WiFi slider on my phone, and it would automatically connect to the network, and I could immediately start talking to the devices I need to (this was excellent!). Then when Lollipop first rolled around, it would still connect to the network automatically, but it would realize that there's no internet connection, so it would then prioritize the Cellular Data network, preventing me from communicating with my network devices. So I had to do an extra step by disabling my data connection, then things would work properly again. (Of course, this also meant that when I wanted to jump off the Wi-Fi, I would need to re-enable Cellular Data.)
Nowadays, Android seems to remember that my WiFi network doesn't have an internet connection, so it never joins it by default (very frustrating!). So every time I want to jump on the network, I need to turn on WiFi, then manually select the network to join, then go into the Data section and disable cellular Data, and then things would be working fine. Of course, if I ever walked away from the Wi-Fi range and then came back, I would again need to manually select the network.
And now with this lastest Marshmallow update, a new Notification pops up every time I join the Network that says:
"Wi-Fi has no Internet Access. Touch for options." When touched it says, "This network has no Internet access. Stay connected? Yes/No" There's also a checkbox that says, "Don't ask again for this network". Every time I check that box, and say YES to stay connected. And yet each and every time I connect to the network, this notification appears again! (The checkbox seems to do nothing). I've looked at the Advanced options in the Wi-Fi settings, and nothing there seems to help.
So my question is, is there a way for me to go back to the "good 'ole days", where I can get my phone to automatically join this WiFi network, and still prioritize it over cellular data?
If need be, I'm perfectly fine with rooting/unlocking my phone, if I need to install some custom firmware or whatever.
Thanks in advance for any suggestions you might have!

Tethering wifi will not work after updating (ota) android 7

Hi,
I suggest that before the update worked perfectly.
After updating the wifi tethering does not work anymore.
In practice, the other device connects but does not navigate.
I noticed that with tethering connected and connected device if I disconnect the data and reconnect them, the connected device navigates but no longer surf the phone.
To be able to surf the phone I have to disable the router and disconnect and reconnect the data.
It's as if either surfing one or the other.
I have already reset my factory data.
My sim has no tethering block.
I've already tried to change APN (default - default,dun - default,supl,dun).
The same problem also in safe mode.
Can someone help me?
Thanks
