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?

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?

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.

I have noticed that my wifi signal strength is crap. I can be in the same room about 4 ft away from my router and my signal strength is 2 bars on my wifi. Also on my 3g coverage I am at 1-2 bars max. When I 1st got my phone never had this problem. Any ideas?

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?

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)?

I need to develop an application which scans the wifi access points and also gives their signal strength.I wrote the code for scanning the access points but I dont know what packages to use for measuring the displaying strength.Can anyone please tell me how to display the signal strength, also give me the code for that.

In an attempt to conserve my battery I've been switching between GPRS & 3G. I only switch 3G on when I need it e.g. browsing the web. Sometimes though, depending where I am, the GPRS signal is better than the 3G so I end up switching back. Is there an app that will show 3G signal strength?

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?

I am using the Galaxy grand I9082 Duos. I have a simple problem in WIFI signal strength, on this device signal strength showing very weak for a distance of 3 to 4 meets away from the wifi router in the next room. But Laptop shows good strength at same point.
If I take my mobile close to router shows very good strength.

I have a Desire on T-Mobile in the UK. Before updating to Froyo, the signal strength fluctuated between 1 and 4 bars. Since updating, it fluctuates between 0 and 4 bars, even when the phone is just on my desk at home.I did a coverage check on T-Mobile's site and the results for my postcode are "good", which they show as 3 bars out of 5.What could be the reason for the fluctuating signal? I would assume that if I was in a weak signal area for T-Mobile, that the signal would constantly be low. Am I wrong to assume this? I can't understand why it fluctuates so wildly for no apparent reason.

Somewhere I came across a number you could dial that would take you into an engineering display that showed signal strength information. Now that I need the information, I can't find it.Can anyone tell me the number I should dial? It had lots of *s and #s, and I think that the number 46 was in there, but try as I might I can't find it on my phone!

I only got the HTC desire yesterday and its my first smartphone.
1. Is there any way of getting the home screen to show what network you are currently connected to?
2. I live in Northern Ireland and have a 3uk phone but work near the border between the republic of ireland and northern ireland. All other phones that I have had allowed me to have a 3uk network connection within my workplace, but now with this phone it will not come off 3Irl and sometimes transfers into O2 Irl, which will cost me a lot if I answer. On 3Irl I can receive calls and messages free but it cost to send out.

I would receive notifications when signal strength changes. I tried to create the following method and call it in the on Create():
private void initializeWiFiListener(){
Log.i(TAG, "executing initializeWiFiListener");
String connectivity_context = Context.WIFI_SERVICE;
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));}

I am very new to android. Need help from Android Developers. Can anyone PLEASE help me how to find current WiFi signal strength in android. I'm trying very hard to get android to display the signal strength. Also, i would like to know if this works on emulator. If possible please provide sample code. I found out the following link but I am unable to write a simple program to display signal strength on emulator/phone. http://developer.android.com/reference/android/net/wifi/WifiInfo.html.

I have justed upgraded to the new OTA firmware, and now I have a new symbol. It's between the mobile strength and wifi symbols, and it's, from top to bottom, a capital L on its side, a / and a filled in square. It's still there with GPS, Mobile and wifi switched off. I can't see it in the manual.

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.

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.

I just updated to 2.2, but I noticed the Verizon network signal is weaker. I used to be able to use 3G connection at my desk at work, but after the update, I cannot receive any 3G signal at the same location. Does anyone have any idea?

I don't know if this is because of Sprint or the EVO but in my house I barely get 1 bar of signal and people can barely hear me on the other end of the call. This is my first Sprint phone so I don't know if it is the service or not. I came from ATT and never had these issues with my iPhone before. I am a little concerned about whether I exchange phone or am I going to just have to give up on Sprint.

I want to know the FM Radio signal strength in Android. For this I have to interact with hardware or not? Or is there any API which can directly give me the value of signal strength?

Could any of you please comment on their Wi-Fi signal characteristics? I average "1 bar" unless I am right next to my wireless router, at which point it displays full strength connection Interestingly there is no significant difference when I run a bandwidth speed test (speedtest.net).

I believe there is a bug in the signal strength indication on the Fascinate, the one that shows the signal strength in -dBm. You can see the signal strength of the cell signal on the Menu, Settings, About, Status screen. Or you can place a widget on your Home screen. There are several widgets available, I'm using Mobile Signal Widget.I have a network extender, which basically creates a cell tower right in your home. With my Motorola Droid, I used to get signal strengths down to about -50 something and 60's in indicated signal strength. I can hold both of our Fascinates right next to the network extender's antenna and they will read no better than -86 dBm. So far I've seen signal strengths from -86 dBm to -106 dBm (terrible).I believe there is a bug in the software (Baseband) on the Fascinate. Previously, I thought the hardware (antenna/radio) wasn't very good, but now it may be software related. Has anyone seen a signal strength stronger than -86 dBm on the Fascinate?
