Losing Wifi everytime!!!

What is with this? I 've gone through several HTC phones on the EVO and everytime I lose my wifi. Anyone can help?

When do you lose the Wi-Fi?
I use the wi-fi in my house and it will maintain a constant signal.
UNLESS
It goes to sleep mode, then it turns off the wi-fi as well.
Whenever I bring it out of sleep, it always has to re-connect.
I don't know if there is some registry setting you can set to keep wi-fi turned on.
I think the risk is that it will drain the battery much quicker though.
I'm using the MAPL build 2.60 beta for a Dash 3G and the battery life is incredible.

You can make it stay on by going to: Comm Manager>Settings>WLAN Settings>Power Mode and unchecking the "Auto turn off..." box. And yes, it does suck the battery like a vampire and makes the phone HOT! You can also adjust how long it will stay on for after LCD OFF.

Wifi question
Hi, before i drive myself mad, I am convinced that my phone uses gprs for data, not wifi. And my bills seem to agree with me.
When I use things like MyPhone, either connected to my PC or connected to my wifi at home, it seems to appear on my bill as a data charge, which would indicate that it is using the network??
Am I right, wrong or stupid? Any help greatly appreciated.

Does "WiFi" on helps to save battery?

I saw several posts suggesting that leaving WiFi on where you have WiFi connection helps you to save the battery which I'm finding pretty strange. I thought WiFi actually drains battery faster then anything else. Are savings due to the fact that WiFi is more efficient then 3G or does it actually holds true that it saves battery?

All things being equal, Wi-Fi uses less power than 3G. Wi-Fi radio waves don't have to go as far, so they're easier to generate. When Wi-Fi is on, 3G is off, so you'll save power if you're actually transferring data.
A lot of programs will initiate data transfers by themselves when connected to Wi-Fi though, so perhaps that is why some will notice higher drain when Wi-Fi is on.
Also, if Wi-Fi is left on and you are on the move, your battery will drain since your phone is constantly searching for available networks.
Unless you've changed the settings, however, when your phone's screen it off it switches back to 3G to handle data.

This however, is untrue. At least for me. I run the leaked 2.2 and my WiFi is always on at home, my data connection is never active. I check this by dialing *3282# and hitting send.

When I have wifi switched on I lose around 5 to 10% an hour. With it off I lose 1 to 2%. I don't have anything set to sync differently via wifi. I only have a few apps that sync data and those are set to do so every 4 hours or so.
I have tried leaving it both on and off overnight to test this and every time I've left it off I woke up with a full battery. If I leave it on I have to charge again in the morning.
When I'm going out I turn wifi off so that my phone isn't constantly searching for signal.

In the Wi-Fi advanced settings (Hit Menu when in the normal wi-fi settings), there is a Wi-Fi Sleep Policy (which specifies when to switch from Wi-Fi to mobile data)
By default, my device was set to 'When screen turns off'. the other options were 'Never when plugged in' or 'Never', I switched mine to 'Never'. You should notice that when you turn your screen on, the wifi icon doesn't show up right away. Of course, I'm on 2.1, so this may be different in 2.2, but check it out.

For me, I get no cell signal in the building at work so I need to keep wifi on. If I turn it off my battery drains fast from the 3g radio constantly trying to lock on a signal.

It depends in the quality of your 3G connection, but all things equal I have seen that using WiFi instead of 3G does save battery, when the WiFi is connected of course. Anytime a radio is constantly searching for a signal or trying to hold a weak signal, power usage tends to go up.

Check out Y5 Battery Saver.
This app turns your wifi on/off based on the cell towers that you are on. You just connect to wifi, enable the app, and it remembers what cell towers you were on while you were in range of that wifi location. as soon as you are off of those towers, it turns off wifi. to add new wifi locations, just disable the app, connect to the hot spot, and re-enable the app.
This gives you the best of both worlds. you get to save battery while you are using wifi and when you are out of range it doesn't continually search for new wifi networks to connect to.

Whenever I turn my screen on, my wifi icon is right there. No delay in it showing up. I don't remember ever changing the sleep policy when I updated so I believe this is the default behavior for 2.2

+1 on Y5. There are a few other apps in the market that claim to do the same thing, but I think Y5 is by far the easiest to set up and works really well. Nice little utility so you don't have to keep remembering to turn off the wifi manually when you are out of range.
Now if I could just find a app that does the same for my bluetooth when it is near my car....but that I think is much harder to do without it actually polling.

[Q] Data "sleeps" and won't wake up (Slim ICS and Air Kernel)

While at work, I don't get very good signal, so I don't surf the web very often. But I've noticed, that when I leave the office, I'll have full bars of service (including the 3G icon) but my phone will act like I'm comlpetely offline.
I'm using the Slim ICS Rom and Air Kernel.
If it helps (and people ahve used the roms/kernel) the signal indicator is usually blue when I'm connected to the internet. When this happens the signical indicator is grey. But it's clear that I have signal, because there are two levels of grey and I'm able to make phone calls when this happens.
Sometimes, if i put it into Airplane mode (which takes forever btw) then turn Airplane mode off, I'm able to regain connection. But anything short of that (or rebooting) hasn't helped.
I've tried searching for a solution, but I might just be using the wrong search parameters. Anybody have any ideas?

Oh, i forgot this is an NS4G.

similar issue occasionally on the stock kernal.
airplane does not fix it on mine
fwiw

WiFi constantly RECEIVING (no apps running)

Basically I am on Nexus S JellyBean 100% STOCK and this issues is happening with work WIFI.
How I noticed it...when I am at home I drop 1% battery on Wifi per hour. 10hours = 10% (sometimes less).
I go to work on the Wifi, I DONT USE ANYTHING ON THE PHONE and the battery is DRAINING LIKE CRAZY!!! 5%/h or more!!!
( I am in airplane mode in both place)
So I was thinking, WTF with this work wifi, i am not doing anything at all on it. Then I look at my wifi icon I have a constant RECEIVE icon. And I bet my phone does not go to sleep or something.
So why in the world my work wifi is draining my battery and the one at home is not. I will check tonight but I dont think I have traffic like this. I am registering 5-6kbytes/s for nothing. There was an explanation given in one of the links below about existing wifi traffic that goes through my phone but I do not agree with it fully. YEs sure there are several pings and beacon emitted back and forth but i do not think it is enough to cause 5-6kbytes/sec . The wifi is not in Monitor mode and it only receives the packets destined to my phone.
This is madness!!!! BTW When I had a different kernel back on ICS this behavior stopped. I will try to monitor again. So there is definitely some kernel switch that can force the wifi to idle.
Here are the links where they discuss this somewhat.

Using WIFI with airplane mode, phone won't connect to Google Servers

Hi guys,
Question is in the title, because of low signal and as I don't get so many calls and SMS (Only whatsapp, skype, etc). I have been using airplane mode with Wifi enabled, everything has been working fine
The first issued apparead when I got an delayed gmail email (We know that in Android, emails comes asap), the delay was around hours! So I checked the status of the connection and the Wifi bars were orange meaning not connection to Google Servers.
As soon as I turn on airplane mode, the bars turn white.
Is that supposed to happen?

Guys can someone try? This is driving me crazy

Not a problem for me.

I can confirm. In airplane mode the phone shows orange instead of white bars on wifi signal. There is however internet connectivity. Everything works as it should, except for google sync - it returns an error. This is what "paints" the bars orange. When you get that it means that google failed to sync one or more items from your google profile. I'd say don't worry about it, it's probably intentional.
I'm running latest slim weekly with franco kernel on top/bottom
p.s. it appears that google sync is down for the moment, nothing to do with our experiment. The last couple of days it was having problems in my area for the most of the day. it's on google's end of things, your phone is fine.

SlimKat 6.8 and FauxKernel 019u. I meant to grab a screenshot of my settings drop down to show the WiFi was white, not orange, sorry about that. But yeah, still no issues here.

Stock ROM, Airplane mode + WiFi = Google Services work okay for me.
