the first day I had the phone, it was picking up wi-fi networks. I got it to connect to my home network, then it disconnected. Everyone I go into settings it is "Searching" and never picks up on my network anymore.I have googled to death. Can anyone suggest what is wrong or how to set this up.

A friend of mine is a member of the EVO Facebook group and sent me to a link which reads as follows:
"For those of you having battery issues I found a way to Dramatically improve the battery life.
First things first, go into Settings> About Phone> Battery> Battery Use> Cell Standby. Assuming your phone has been on, or off the charger for ~10 minutes, it should show Time Without Signal at around 50%. Next thing, press Home and bring up the dialer. Dial *#*#4636#*#* (Do not press "Call"). After a second, it should bring up the "Testing" menu.
Go into Phone Information, press MENU, and tap "select radio band." You should experience a Force Close, don't panic, this was supposed to happen. Scrolling down shows that the preferred network type is GSM auto (prl). What this means is that even though you are connected to a CDMA network, your phone is trying to find a GSM network, preventing the radio from sleeping, and causing excessive battery drain. Remedy this by tapping GSM auto (prl) and changing it to CDMA auto (prl).
Now your done, your TWS should drop dramatically, and you should experience much better battery life!
Note: You need to do this every time you reboot."
I've changed it on my phone just now and the service still works as normal. I guess we'll see if the battery life increases. If this works and with overclock widget I should be getting some crazy battery life now!
Not sure if any of you guys have the same problem but when I leave my Wifi on all day, and return home from work, my home Wifi never picks back up. When I toggle my Wifi on and off, it picks up again. My signal is always above 1 bar when on Wifi in my house, it just does NOT automatically connect anymore.
View 4 Replies View RelatedI have a S4 (SGH-I337M) with Android 4.2.2 installed on it, Not Rooted, Not unlock. I can't access to mobile service network, my SIM card works with other phone, but when i plug it in my galaxy s4 it detect network for 2 ou 3 seconds then it turns to No service and than detect for 3 seconds and ... so on. i have tried to search for available networks (setting-> other network -> mobile-> search for networks) it displays error while searching for network.
I tried many options, reboot, filght mode on-off, recovery, reset, and nothing worked.
Is there a way to tell if u are picking up a signal?
View 5 Replies View RelatedIs anyone else not getting a mobile internet connection right now? This has happened before on Orange but it's different this time because my phone doesn't seem to be searching for a network to join (before in the settings it would say "searching" or something and be greyed out but not this time)
Hopefully it's just a network problem, rather than my phone
I've managed to fix it i think. It would seem something I installed (im thinking SwitchPro Widget) changed the APN name in the settings to orangeinternet_off.
A) The data network access doesn't work anymore. B) The touch screen is not responsive freezes a lot.C) The text messaging freezes then sends out 20 of the same message.And I have done numerous battery breaks.
View 4 Replies View RelatedI've had my HTC Hero for one week. First day I got it, I walked into a Radio Shack and connected to the open WiFi instantly no problem. I can connect to any secured network (w/ pwd) no problem. However, ever since I put the phone in airplane mode while on a flight, I haven't been able to connect to any open Wifi network. The Hero detects the network and says I'm connected, but I can't get on the internet at all. The phone says it's not in airplane mode but maybe it still is? help please. I'm running android 2.1.

View 3 Replies View RelatedI have two android devices at home, a HTC One S and a Nexus 7(2012). The problem is that when I am using one or another occasionally the wi-fi will simply stop working. I'm still getting full signal in the notification bar, but either Chrome or whatever app that is using the wi-fi will stop retrieving data and eventually time-out or stay on buffering.
I have tried some things including changing the channel my wi-fi is set to from Auto to 6 and Mixed B/N/G mode to N only, but nothing seems to fix this problem except for one thing; turning the wi-fi off on one of these devices. The connections seem perfectly stable when I do this.
I also have a laptop in the house, my girlfriend comes over with her iphone, and I have an ipad from work that I occasionally bring home (I'm a teacher) and none of these devices ever have any issues, it's only the two android devices.
It's almost as it they are sharing the same wi-fi train track and only one can ride it at a time.
Are we able to establish both WiFi and 3G connections at the same time on Android 2.1? We are implementing a "make-before-break", so that WiFi can be switched to 3G before tearing the WiFi connection down. Please guide if you have come across this.
View 2 Replies View RelatedI have a WiFi network at work and it requires a New password generated from a secure token each time when I try to re-connect. Since Android WiFi setting remembers the password, if it try to re-connect using the saved password (it becomes invalid after disconnected), my secure token become invalid. If I remember to remove the connection each time after I disconnect, I can enter new password when the connection is discovered as a new connection again. The problem is what if I forget. In addition it is inconvenient. Do you know any Android application supports remove a chosen WiFi connection password each time the connection is lost?
View 1 Replies View RelatedI am writing an app that connects to a telnet server via wifi. I have a service that manages the socket connection. It all works fine, but when the phone sleeps it disconnects the wifi radio, which causes the socket connection to break (and throws a SocketException). I feel like I should be able to set up a a broadcast receiver whose onResume() method is called when the wifi network connection is lost, and that would allow me to gracefully shut down the socket, and re-open it if the network is immediately re-connected. But I can't find anything like that in the doc or via searching.
View 2 Replies View RelatedIt seems the java.net.NetworkInterface implementation of android does not have a byte[] getHardwareAddress() method http://developer.android.com/reference/java/net/NetworkInterface.html
I've found several forums of people trying to do this with no definitive answer, I need to get a somewhat cross-device UUID, so I can't rely on phone numbers or in ANDROID_ID (which can be overwritten and which I think depends on the user having a google account http://developer.android.com/reference/android/provider/Settings.Secure.html#ANDROID_ID
In linux you can use ifconfig or read from /proc/net/arp and you can easily get the Hardware address.
Is there a file in android that I can read?
There has to be a way to get this address since it's shown in the "Settings > About Phone > Status" of the phone.
Okay, here's the deal. I have a stable WiFi network, an Android phone (HTC Tattoo), and a computer. What I don't have is a way to get said computer to connect to the WiFi network, seeing that I don't have a wireless card.
The question I want to get an answer to is simply this: Is there any possibility to use my android phone as a wireless card, thus get my computer online? Or do I have to go out to get a wireless card? I don't want to use 3G, seeing that it's slow, and the WiFi net is included in my rent.
Android developers can check this code to check the network status on wifi and 3g mobile
You need the following permission to get status view source print? 1 <uses-permission android:name="android.permission.INTERNET"></uses- permission> 2 <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"></uses- permission>
I have an Eris with Android v. 2.1 and a Belkin 54g router. The phone lists my home network in its list of of wifi networks. When I press the entry, an info box says that signal strength is good and security is open. (for the purpose of trying to have my phone connect). When I press "connect," it says "Obtaining IP address." Then after a couple of minutes, it says "Unsuccessful."
My phone has connected to other WiFi networks with no problem; indeed, it has done so automatically, with no effort on my part. My router assigns IP addresses via DHCP. It also broadcasts its SSID, which the phone recognizes.
Is there any way for an application to force a network request to go over the mobile network if it's available in preference to WiFi? I'm looking at ConnectivityManager#setNetworkPreference, but there's no documentation, and looking at the source seems to suggest it's setting a global preference somewhere which isn't what's required here - I just need to force certain requests that need to go over the mobile network to ignore WiFi.

I have an android application that parses some HTML, downloads an image, and displays it. I'm using an AsyncTask to do the HTML parsing and image downloading, but that shouldn't be relevant. I never have a problem when I'm on WiFi on my phone, when I'm using the Eclipse debugger on my phone, or when I'm using the emulator. When I have my phone on the cell network (even with pretty good reception), the image sometimes fails to display. I'm having a hard time figuring out what is wrong, since the problem cannot be reproduced in the debugger. Does anyone have any idea what could be wrong?
Update: I have narrowed it down to the image downloading function. This way my original code:.......................

The device showing that is trying access the network, but after some sec. the connection is failed. I tried reset the router, but it still failed... I dont have any other wifi connections in my range so i cant check for another wifi connection.
