[Q] Fixing Wi-fi without reformatting? - Galaxy S I9000 Q&A, Help & Troubleshooting

Hey, in the last few weeks I've run into a very annoying bug on my phone. Wi-fi turns itself off after about 2 minutes. It doesn't actually "turn itself off" in the phone - and by that I mean that the wifi icon is still there, and I can see the signal strength, but the internet won't work.
In order to fix it, I have to turn the wifi off and then on again.
I've tried using the Wifi Fixer application, but it doesn't help. It can't seem to detect when I lose my internet connection.
I've also troubleshooted it, checking that it occurs on different routers/types of networks.
I'm sure it's a problem with my phone, but I dont really want to reformat my phone until Froyo comes (since I don't want to have to install all my apps twice).
Is there any solution to this? ;z
I'm on stock rom, JF3, with OCLF.

I have the same problem with my phone. My Wi-Fi at home works just fine, but when I go to my brother's house, I seem to occasionally lose internet connection even though it shows that it's still connected to the Wi-Fi. I have stock Bell ROM with OCLF by RyanZA. Oh, and to fix it I simply turn Wi-Fi off, and then on, and it starts working again.

Bump :x
Anyone have a solution?

Wifi connecting issues..

When im home, i like the phone to stay on Wifi at all times. It won't do this even if i have the thing configured to stay on while in sleep, so It drops the connection after a while. When i wake the N1 it won't connect automaticly. I have to turn wifi off and on to get it to connect. Quite annoying.
Should i reflash Cyan rom or get a different Kernel or do someone have an easy solution to the problem?
Thanks in advance..

[Q] WiFi Freezing

Last week, I decided to finally unlock, root, and flash a custom ROM onto my Sprint HTC One. I started with the LiquidSmooth 3.0 Beta, which I really like, but encountered some issues with the WiFi connection.
Essentially, my WiFi connection will, at various times, stop working. When this happens, my phone still shows as being connected to the WiFi AP. Sometimes, I can get my data working again by turning WiFi off and then back on. Other times, after turning my WiFi off, it will refuse to connect to anything when I turn WiFi back on. At this point, I have to reboot my phone to get WiFi working again. Once, the WiFi started working again about 3-4 after I had noticed it wasn't working.
The WiFi generally seems to work best at home, where I have just 1 AP the phone connects to, though it will still sometimes freeze. It is much worse at work, where there are multiple APs as you move throughout the building. When the phone was using stock, the WiFi would usually take a minute or so to regain data when moving between different areas of the building, but now it usually just never regains connection. The notification will show that it is connected, but with 0 signal strength.
Looking around, I've seen that some other people have had similar situations. I tried the solution of renaming my device in the WiFi Direct settings. This seemed to make the WiFi work a little better at home, but no different at work. Some other people said they flashed a newer radio, but I seem to have the latest radio on my phone. And this issue is not related purely to LiquidSmooth. I tried out the SlimKat ROM and encountered the same WiFi problems.
Any suggestions would be appreciated.

Moto G (Dual Sim) Internet Connectivity Issues

Hi, I'm new here so forgive me if I do something wrong^^
First of all, I have a Moto G 2014, Dual Sim which is running on 5.1.1, to be more specific, this ROM. I was using this ROM for about 4 months already so that shouldn't be the issue. My problem is that after my phone connects to the internet, usually using H+. The connection to the internet is working perfectly fine, but after a while of not using the phone it loses the connection. It still tells me that it got a strong H+ connection, but nothing (browser, apps, anything) is able to connect to the internet. Enabling & disabling airplane mode usually fixes the problem. From time to time it also happens, usually when I lost some sort of wifi connection (regardless if I disabled wifi or I got out of range) it happens that it shows full connectivity but with an exclamation mark. This only goes away if I reboot or enable & disable airplane mode again.
Is this issue known/is there any solution to
I have been experiencing the exact same thing as of lately. I thought it was a byproduct of downgrading from (Stock) Marshmallow to (Stock) Lollipop (yes! it's happening even on stock ROM) where at times the WiFi losses connectivity when the phone had been sleeping for awhile...even though I have the "Keep WiFi on during sleep" option on under WiFi's advanced settings. I had no idea that it also happens with data connections ! ...as I don't use it (too expensive for me), now I'm uncertain what could be the cause. I can see how this would be an inconvenience if you use a lot of social media apps as I sometimes do not get my WhatsApp messages when this happens and sometimes I don't even receive my Hangouts messages until I open the app manually.
It's strange, at times when my phone sleeps for awhile and it losses connectivity and I wake it, it will reconnect just fine and other times it just goes into this state where it reconnects with full signal strength but with an exclamation mark next to the WiFi icon in the notification bar. When this happens, no matter what I try it stays in this state, I tried turning off WiFi and turning it back on, also forgetting the network and entering the info and reconnecting to it but none of that works. I didn't know that turning on and off airplane mode can help....I'll have to try that one, rebooting the phone was the only solution I found which is just inconvenient and somewhat annoying.
I too, am interested in a proper solution. I don't know why the phone ignores the "Keep WiFi on during sleep" option or why at times it connects but have not internet access! It should be noted that it's not a problem with the network, It's not due to an incorrect password or anything like that as I am the one that administers those things and when it happens other WiFi devices such as my Tablet PC, Laptop etc can connect and access the internet just fine and it only happens sometimes on the phone (Moto G 2014). This doesn't seem to happen in Marshmallow...but I hate Marshmallow and I can't remember having this issue on Lollipop post Marshmallow update (how I wish I had never tried out Marshmallow!!!), which is why I thought it was related to downgrading, .......did you downgrade ?

[Q]Suddenly losing WIFI connection when phone is idle

Hello.
I am using my I9000 for a good while now and i am running cm11-20150901-SNAPSHOT-XNG3CAO3G0-galaxysmtd. Everything was running fine so far, but suddenly for some days now, the WIFI connection somehow gets lost when it's idle.
When this happens (and i don't know on what timeframe it does) and i activate the phone (pressing the home button) the WIFI symbol is either shown and then disappears or is already gone - but then after some seconds comes back and WIFI is on again.
Yes, i do have the setting for standby WIFI on always, so this should not happen.
Does anyone have an idea what could be the problem here?
Also i do have a fritz.box 7390 which supports a 5GHZ network - does the I9000 support a 5GHZ wifi? Maybe it's the router that's causing the issue an switching to the 5GHZ might fix it - but so far i could not see the network when it's on 5GHZ.. So i guess it's not supported but thought i might ask anyways...
Thanks!

WiFi connection problems after update

Hay guys,
I am really at a loss, so I hope you can help me here.
WiFi on my phone works totally fine until I install the EMUI Update 10.0.0.185 (and later).
From that point on, I can't use my WiFi at all. The Phone is still showing me a list of all the available Networks, but If I want to connect to one of these, the phone's WiFi turns off by itself. Just du turn itself on again a few seconds later... and turning off again eventually.
This happens to all of the WiFi networks, I've tried. Also I can't setup a WiFi hotspot anymore or use wireless display feature.
If I reset my phone to the EMUI-Version it came with, everything works flawless.
Any idea, what could cause the problem?
