Android :: Signal Strength Of Each WiFi Access Points?

Aug 9, 2010

I am building an application reading the signal strength of each available WiFi access point. I've written code like:

wifi = (WifiManager) getSystemService(Context.WIFI_SERVICE);
// Get WiFi status
WifiInfo info = wifi.getConnectionInfo();
textStatus.append(" WiFi Status: " + info.toString());
// List available networks
List<WifiConfiguration> configs = wifi.getConfiguredNetworks();

However, I have two problems:
In debugging, configs only contains one connection. However, I can see that there are several APs available in the system's wifi setting. i.e. configs is an incomplete list. I don't know how to get the signal strength in Wifi Configuration. I am using HTC Hero and Android 1.5.

HTC EVO 4G :: Wifi Signal Strength Suck?

Jun 9, 2010

The wifi indicator sometimes only show 1bar. Meanwhile i sitting maybe 10 feet away from my modem/router. Speed test shows me getting 3200 kbps down and 1200 kbps up.With two bars I am getting 8700 down and 2400 up. I never get 3 bars. Any analysis of these numbers? Are they typical? Anything I can do to achieve 3 bars?

HTC Desire HD :: Wifi Signal Strength Fluctuates?

Oct 31, 2010

I have been an avid iphone user for the past 2 years, but with having went through 4 iphone 4 handsets and still not happy i decided to make the jump. anyhow, on to the matter in hand, is anyone having wifi signal strength issues? If i'm close to the router. i.e 5-10feet and line of sight, it works fine, with 3 bars. but if i move farther away say into my kitchen, 20ft and through plasterboard walls it will drop to 2 bars. this is understandable, but it will then fluctuate between no bars, to 3, then to 1 then 2, then 3, then..... you get the drift. i can accept strength deterioration with distance, but for it to be so erratic i find it a bit strange. i have changed the channel my router broadcasts on and it hasn't made any difference. other than that very happy with the phone, just getting used to Android. Is anyone else noticing this with their wifi? all my other devices have a constant strength, be it 1, 2 or 3 bars and no erratic behavior. is it faulty wifi, should i sent it back to Amazon for a replacement?? or is it just the way it is?

RSSI - Application To Read Signal Strength Of 3G / GSM / WiFi

Mar 17, 2009

I'm developing an application to read signal strength of 3G, GSM, Wifi.

Is there any classes that provides us with the RSSI of 3G signal and GSM signal?

The WifiManager Class provides the RSSI for wifi, but I can't find any for 3G and GSM. If there is no classes provided, is it difficult to start from scratch?

General :: Droid X Says WiFi Signal Strength Poor To Nonexistent

Oct 10, 2011

I am virtually unable to get a wifi signal in my house on my droid x unless I am a few feet away from my router. None of my other wifi devices in my house are having this issue. When I check my wireless settings on my dx it says the signal strength is poor. I'm running rooted GB 4.5.602. Does the baseband have to do anything with this (BP_C_01.09.13P)?

Samsung Moment :: Signal Strength Apply To Data Signal Or Just Voice Signal?

Nov 4, 2009

I want to reach out to others here before I take my Moment back to Best Buy to exchange it for another Moment.

My signal strength fluctuates wildly just sitting in the same spot. With the Hero I got a constant 5 of 6 bars, but the Moment will vary between 0 and 5 of 6 bars. But it's more complicated than that.

It seems that whenever the EVDO data kicks in, it causes the signal strength to drop to 0 or 1 bar. Once the data is idle, the EVDO indicator turns grey and then changes from EV(^v) to EV(D). At that point the single strength will return to 3 or 4 bars.

At times, though not as consistently or often, the EVDO connection will fall back to 1xRTT and will switch between them every few minutes. This will occur even when the signal strength bars are in the 3 to 4 range.

So, the my questions are...

Does the signal strength apply to the data signal or just the voice signal?

Is there any legitimate reason for the signal strength to vary wildly like I've described, even when sitting in the same recliner where the Hero had a constant 5 bar connection and data service that never wavered?

Is anyone else having signal strength and/or data service issues?

Should I exchange the Moment for another Moment or will I likely experience the same issue?

Android :: Connecting To Strongest WiFi Access Point

Sep 9, 2010

I have two WiFi access points in my house, due to thick walls. When I turn on my phone it searches and connects to the first access point it finds, which is not necessarily the one with the strongest signal. e.g. I have one access point on channel 10 (lounge) and another on channel 1 (bedroom). When I'm in the lounge it always connects to the A/P in the bedroom, unless I actively "forget" that network, even though the signal strength of the one in the bedroom is VERY weak. Is there a way to force it to pick the strongest A/P?

Android :: Manual IP Settings - Per WiFi Access Point?

Nov 22, 2010

I have a question regarding WiFi setup on my Android. When I'm at home, I want to use manual IP settings for my WiFi (instead of relying on DHCP). However, when I'm out using other WiFi (a coffee shop, or at school) I obviously need DHCP. How do I set manual IP settings on a per-wifi-hotspot basis?

Android :: Code For Scanning WiFi Network - Null Point Exception

Android :: Wifi Connection - Connect To Access Point With Specific Name

Oct 1, 2010

I have an application in which I need to connect to an access point with a specific name. Therefor I start a scan (WifiManager.startScan()) and listen to BroadCastEvents of type SCAN_RESULTS_AVAILABLE_ACTION and NETWORK_STATE_CHANGED_ACTION. When the scan results are available, I check if my AP is found and if so I connect to it.

When I'm connected to the AP, I receive a NETWORK_STATE_CHANGED_ACTION and there I open a SocketConnection to my serverSocket. The problem I'm having is that on the moment that I'm connected to the AP, the DHCP request is not yet finished. This causes the opening of the socketConnection to throw a "SocketException: Network unreachable". A few moments later I see in the logcat logging: WifiStateTracker - DhcpHandler: DHCP request succeeded. If I try to connect after this message, all goes fine. is there an event that I can listen to that informs me that the DHCP request is done? Now I try to create a connection and while an error occurs I retry. This is however very dangerous for hanging (if e.g the dhcp fails, the loop will never stop...)

final WifiManager wifi = (WifiManager)getSystemService(connectivity_context);
if(!wifi.isWifiEnabled()){
if(wifi.getWifiState() != WifiManager.WIFI_STATE_ENABLING){
wifi.setWifiEnabled(true);}}
register Receiver(new BroadcastReceiver(){@Override
public void onReceive(Context context, Intent intent) {
WifiInfo info = wifi.getConnectionInfo();
//TODO: implement methods for action handling}
new IntentFilter(WifiManager.RSSI_CHANGED_ACTION));}

Android :: Neighboring Cell Signal Strengths Better Than Those For Current Cell Signal Strength?

Jan 6, 2010

I'm writing an android application that collects cell signal strengths. I am having trouble getting the "current" cell signal strength, but I don't have any problem getting the "neighboring" cell signal strengths. To get the current cell signal strength, I created a PhoneStateListener and implemented the onSignalStrengthChanged callback. It works, but not very well. It seems like the signal strength hardly ever changes, and resolution jumps to only a few numbers. I would accept the answer that the resolution of the signal strength hardware is coarse, but when I use the TelephonyManager's getNeighboringCellInfo() method, it works much better. The signal strength readings from neighboring cells change frequently, and they have much better resolution.So, how can I get the current cell signal strength in the same way that I am getting the neighboring cell strengths? It seems odd to me that the functionality of the neighboring cells is better than the current cell. Am I missing something here?I would also like to directly call a method from the telephony manager to get current cell strength, as opposed to a listener, if possible. If anyone knows how, please let me know.

Android :: GPS Signal Strength

Jul 17, 2010

I'm guessing that the GPS hardware in most Android phones is the same or close. If it makes a difference I have the Moto Cliq XT.I'm going hiking tomorrow and will be using Google's My Tracks program. I've tried it twice... the first time I could not get a signal despite being out in desert with nothing to block the signal. Next time I was in the mountains and once I had a signal, it was rock solid. Worked like a charm. But I did not want to take a chance and held it in my hand the entire time. I'm wondering if anyone has tried it while the phone was in their pocket. Any issues with sat lock on? This would be much easier. I also can't imagine that you'd not be able to use GPS while the phone was in your pocket as it's not really possible to have it in your hand all of the time.
