[Q] wifi does not connect automatically

I'm running infused 1.5. Whenever i go to new places that have wifi ( password already been saved), my phone won't connect to it, worse thing, when I scan, it won't see the wifi ssid...it keeps showing the previous ssids that it found earlier. After I turn off wifi and turn it back on, then it acts normal again (connects automatically to that wifi). It acts weird again when I go to another place.

I have the same problem, but I'm stock other than root, so I don't think it's the rom.
I recently added access points to extend the range of the two wifi networks I connect to most often. It almost seemed like it wanted to treat the new access points as new SSID's, which I have always assumed was part of the problem. I just haven't had much time to work on it.

I'm using stock Tom and this has been going on since day one.

Any resolutions here? I just got an infuse 2 days ago and I'm having this problem.
Is this an issue with every infuse or should I exchange it? additionally, if its a problem with all of them, are there any custom roms out there that address this issue?
This is a killer for me, and I'm constantly moving around in an office without consistant wifi so I have to turn wifi off and on like 20 times a day to make sure I just use wifi for data. Very annoying.

Same issue here. Seems to only do this at home with a Netgear N600

You guys need to provide more details. Exact roms and your wireless settings and what security the network is on.

No fixes that I have found so far, unless there are some broadcom DHD commits in pershoot's Galaxy Tab 10.1 kernel I can kang. (The problem seems to have gone away with the latest of is kernels for the 10.1.)
We have the same Broadcom wifi chipset as the Tab 10.1 and many other phones - this is a common issue across all devices with that wifi chipset. Some sort of sleep/power management bug in the kernel driver. Broadcom sucks.

I have this same issue with my Infuse, Infused ROM 1.5.3, kernel 2.6.32.9.
Typically I connect to 2 AP's, one is WPA2 personal, and the other is WPA Enterprise, PEAP, MSCHAPv2
I usually need to turn wifi off and back on in order to connect to my saved profiles.

95% certain rom/kernel doesn't matter - hell, device doesn't even matter. If you've got a Broadcom BCM4330 wifi chipset, it'll happen.

It's the rom! I had the same problem on stock Froyo and now I'm on gtg465x's GB 2.3.3 infused V2.1.0 and this problem went away.

Anyone else confirm improved wifi with this rom? Especially the connecting/disconnecting loop?

Note that my last post on this subject was when Gingerbread had only been out for a few days:
It seems that the issue is fixed in the Rogers Gingerbread kernels. I'm actually surprised, since the Honeycomb kernel for the Tab 10.1 is in theory newer but it has the problem. However, even that kernel stopped having problems after the maintainer made a bunch of power management tweaks.
So basically any Gingerbread kernel should be OK.

That means I will have no hdmi and 15fps video capture though, right?

[Q] My wifi turns on and off

Hey there,
I'm having a weird issue with my stock Nexus S. I've tried a few custom roms, but after realizing that I was better off with stock, I flashed stock again... Now, I've noticed that sometimes, with the WiFi off, I would receive emails and Google+ notifications! It turns out that my wifi is turning on and off, and I don't know how!
I don't have, to my knowledge, installed a program that controls wifi(if you want, I can post my list of apps).
So, what's happening here? Anyone has any idea?
Thanks

Ditto here

You have the same issue? Can you post your list of installed apps? I seriously don't know what's going on!

This may seem really obvious - but have you double-checked that those notifications aren't coming in via your mobile network?
If you have Juice Defender (or something similar) installed, that might also be responsible for switching on your wifi periodically.

Nothing like that... I was just activating my alarm clock for tomorrow and the wifi came on, out of thin air! It shutdown in less than a second, too! And I did absolutely nothing!
Also, I don't have any app like Juice Defender

Ok, so I've flashed the stock rom,locked the bootloader, etc, and I thought I had solved the problem. I didn't, the thing keeps turning on and off!!
I'm seriously thinking about sending it for repairs

you could send it in to samsung or install some newer 2.3.5 kernels which seemed to solve any wifi issues i may have had. Android 2.3.5 made some changes to wifi signal strenght.

I have stock, and it's the regular nexus S, not the 4G one (so I haven't received 2.3.5 yet).
I'll try installing the 2.3.5 kernels and report back

check your advanced wifi settings.
by default they are set to turn wifi off when screen is off. so even if you have wifi on it will turn off when screen is off automatically.
menu>settings>wireless and network settings>wi-fi settings>menu(softkey)>advanced>wifi sleep policy>check the "never" radio button.

I wish it were that simple... I've the wifi sleep policy set to never since I can remember. I only turn on wifi when I need it

Wifi won't disconnect after going out of range

I'm running Hellfire 2.1 and I have a strange issue. The wifi randomly won't disconnect after going way out of range for a long time(like I drive away from house and check phone 30 min later). Accessing the net results in connection timeouts etc, but wifi still says "Connected to XXX". The only way to fix is to manually disable wifi and reenable.
I tried both faux and trinity kernesl. Same thing. Tried fix permissions/clean re-flash with all the wipes, same thing.
Any advice? Thanks.

Never heard of the issue I'm on the same rom what was the install process?
Sent from my LG-P999 using xda premium

1.Flashed latest CWM via NVFlash
2. Ran Nullifier dual wipe
3. Installed Hellfire 2.1 Rom via CWM
4. Installed GApps as provided in the HF 2.1 post
5. Rebooted, didn't touch anything for 10 min
6. Set up Google account, set various settings etc
7. Rebooted again. Waited another 5 min
First noticed the problem soon after I started using the new rom. A day later, I flashed 0.48CM faux kernel. Same thing happened once. Flashed to Trinity ELP, experienced a couple of application crashes, flashed again to Trinity T15. (didn't encounter the problem during the very short period of ELP). Did a couple of intentional tests on T15, wifi disconnected OK. But one day later, the issue randomly came back.

I believe it's just a known G2X bug.
Happens to me on EVERY ROM. Custom kernel or stock. Minor inconvenience in my opinion.

I've had the same issue from time to time on stock ROM as well as various builds of cm7 with stock kernel and with morfic's ELP kernel. Doesn't happen too frequently though so I just toggle the wifi when I have to. I reboot the phone a few times a week and I get the problem less now than I used to.

It only happened to me when I used public networks, like at university for example. I think the phone tries to connect the network with a very weak signal and as you walk it receives signal or not depending on where you are. Powering off the wifi fixes the problem

Thanks to all the replies. Glad to know it's not a software issue and I'm not alone.

Wi-Fi "hidden disconnect" issue

Hey out there.
The other day I flashed AOKP JB Build 4 onto my Nexus S (i9023) and after about one day I got very annoying Wi-Fi issues.
The phone drops the connection every few minutes while the Wi-Fi icon stays blue.
I tried Matr1x kernel in the meanwhile which didn't fix the issue.
Yesterday I had enough of it and tried flashing Codename Android 3.6.6.
At first Wi-Fi was working quite good and I got all hope up but today I'm having the same problem again.
I was on Stock 4.1.1 before and I didn't have any issues like this.
Any help is very appreciated.

Did you try go into Wi-Fi settings and uncheck "avoid poor connections"? That helped me commentary somewhat, but my still disconnects from time to time..

Yes, I have

Is this when the screen has turned off or while its on?

Both.
It's happening e.g. when I'm watching for a YouTube video. So I gotta disable and enable Wi-Fi to be able to continue watching the video.
But it's also happening when the phone is turned off so that e.g. I don't receive any emails in that time.

I got Wi-Fi Fixer working in the meanwhile and it's just reassociating and reconnecting every minute :/

[Q] P6210 random reboots

Hi,
Do you have any idea why my Tab Plus WIFI started to reboot randomly a few days ago?
It was not dropped, not installed/upgraded anything before, I do the same thing (reading web pages) on that. It doesn't depend on how much the battery is charged. It has the stock 3.2 firmware, and was never updated. I own this tablet since last summer and use daily without any problems.
I use the option "turn off wifi while sleep" since bought, but the reboot is related to the wake-up procedure. When I wake up the tablet from sleep, it starts working, finds wifi, but reboots in a minute. Not always, every 3-4th wake-ups, when wifi was slept (was in standby for >15mins). Not application dependent, it did reboot in youtube, simple settings menu and browser, too.
The only pattern in it is that waking up with wifi slept, and within 1 minute.
What can it be? Thanks in advance!

It seems it's related to WIFI wake-up, because yesterday it just rebooted a few secs after turning on WIFI, and did it 3 times in a row (reboot-turn on-reboot...). But after it is turned on, it works like charm.
I don't know how it can happen, it never happened before, but happens 2-3 times a day since last week.
HW failure maybe? No software component was installed, changed or updated since weeks.

Check Apps > Settings > Storage; you may be running out of available memory. If so, move some files off to your PC.

Why not flash your firmware?

I have no newer firmware than 3.2 in my region. And in fact, I don't need it as I only use this tablet for reading web pages and watching some youtube clips, nothing more.
What I don't understand is why an untouched system starts this random rebooting behavior. But as I see from replies, this is not a usual thing, so it might be a hardware issue.

Here's a post you may find helpful - http://androidforums.com/samsung-galaxy-tab-7-0-plus/556111-random-reboots.html

If it is because of the wifi sleep function.. why not turn that to never?
And just manually turn on and off your wifi..
Did you try that?

Wifi sleep policy was set to turn off when sleep. I read about this problem in 4.0.4 but never experienced it in 3.2. I use this tablet since last summer and never rebooted. But now, I'll try this trick and hope it will solve the problem. Thanks guys.
