Android Phone: temporarily avoiding poor connections and DHCP issues

Got a Huawei G526, it sometimes fails to connect to my wireless router(DynaLink RTA 1046VW) and displaying Temporarily avoiding poor connections and the WIFI signal strength is Excellent. I found:

Restart the wireless router can fix the issus most of the time.

However, it is very unconvenient that you have to restart the router every time when the problem occurs. And I do not think it is the problem of the wireless router because other devices connect to the router without problem. (Also I found the Android phone works without this problem on other wireless routers/networks. So it must be a compatibility issue between the andoird phone and my wireless router.)
Then I found how to disable Avoid poor connection:

Go to Settings
Turn on WIFI and get into WIFI
Touch Menu key then select Advanced
Uncheck Avoid poor connections

Now reconnect the WIFI, I got the WIFI status connected. However, I found I cannot actually connect to the internet because there is no IP address assigned. To check if the IP is assigned:

Go to Settings
Get into WIFI
Touch Menu key then select Advanced
See IP address

Why other devices can get DHCP working without problem but not this Android phone? I found it is an caching issue of the DHCP client on the Android phone. You can clear the DHCP cache and restart your WIFI to fix the issus if you have adb or root access.

However, not everyone can root the device or know to how to use adb. And every time the problem happens, you have to clear the cache. My solution is now using static IP instead of DHCP:

Go to Settings
Select the network and hover for the pop up menu
Select Modify network
Scroll down and check Show advanced options
Change IP settings from DHCP to Static
Set IP address to 192.168.1.10, change it according to your wireless router.
Set Gateway to 192.168.1.1, change it according to your wireless router.
Network prefix length: 24
DNS 1: 192.168.1.1, change it accoring to your wireless router.
Click Save button.

Stock Android SIP client set up

Native SIP clients available on some 2.3/4.0 phones. To enable it:

Settings -> Internet call settings
Click Accounts, then click "Add account" button
- User Name: 888XXXXXXX (Your VOIP account number given by you VOIP service provider)
- Password: XXXXX (Your VOIP password)
- Server: sip.pennytel.com (Your VSP's sip server)
- Tick set as primary account

Now you should be able to make calls through your VOIP if WIFI is enabled. (VOIP via 3G is disabled.)

Android: force apps to install to SD card without root

The android apps can be installed/moved to sd card if the application supports it. However, not all the applications support this. And the default install location for the apps is internal storage which is most likely insufficient. The following approach can change the default install location for the apps to sd card (external storage). which means the all the apps will be installed to sd card. (and it does not require rooting the phone):

Install android sdk and connect your phone to your computer.

Run the following adb commands:

cd /path/to/android-sdk-macosx/platform-tools
./adb devices
./adb shell pm getInstallLocation
./adb shell pm setInstallLocation 2

To check the install location:

./adb shell pm getInstallLocation

it should return

2[external]

Note

In Android, Install Location has 3 values:

0[auto] – Let the system decide the best location
1[internal] – Install the application on internal device storage. This means any internal storage provided with your device
2[external] – Install the application on external media. This means any SD, microSD cards attached to your device.

The default value is 0[auto]. You can revert back to the default using the following adb command:

./adb shell pm setInstallLocation 0

On Windows, you might need to install the USB driver to connect your phone to your computer to run the adb commands.

connect to your android phone using adb on Mac OS X

Download and install Android SDK. adb (Android Debugging Bridge) is located at platform-tools/ directory.
Connect to your android phone using adb.

2. Connect the phone to your Mac using the USB cable.

Now you can run following adb commands to connect to your phone:

It should return something like below:

* daemon not running. starting it now on port 5037 *
* daemon started successfully *
List of devices attached 
352810040135572 device

You then using adb commands on your android device, e.g. adb shell to browse the phone's file system.
