Known Issues/FAQ:

Task Killers

Important: Wifi Fixer's wifi health monitor service can be rendered inoperable by task managers and auto task killers.

It is strongly recommended that you do not use Wifi Fixer with this kind of software, but if you must, add WifiFixerService and LogService to the allowed list.


Too Many Networks

Important: Having too many Known Network entries can slow down your phone and burn more battery.

This is an Android issue.   If you have more than 10, try to remove unused or infrequently used networks.


Unable To Scan for Networks or Wifi Not Turning On

On the original Samsung Galaxy and several other devices, Wifi may become unable to turn on, with or without the message " Unable To Scan For Networks " displaying.

At this time wifi may become unusable.

It can be fixed either by removing all your wifi network entries then rebooting the device or going into Settings:Privacy and doing a factory reset

Note: You will lose all your settings if you perform a factory reset.

I wish that I could fix this problem, but it's in the phone's software.

Rebooting or factory resetting is a temporary fix. In order to solve the problem permanently, you must update your device's software or root and install a custom rom.


Wifi Sleep Policy

On some devices, Wifi Sleep Policy appears to be ignored when the screen is off.

This is caused by wifi power save mode, which is not compatible with some wifi access points/routers.

There is a workaround, "Nexus One Sleep Fix", in Advanced Options which may help.

Note: The workaround will temporarily disrupt the wifi connection when your screen goes off.

Set Wifi Usability to Max Wifi before enabling the workaround, and set Wifi Sleep Policy to Never

Cyanogen Mod 6 and above have a driver fix for this issue:

Known Networks

The Known Networks panel may not show any networks when wifi is disabled.

The network list cannot be loaded when wifi is off on pre-Honeycomb devices.


Other Wifi Apps

Wifi Fixer may conflict with other apps which use the Android wifi manager.   Try disabling the service when using conflicting apps if you have an issue. 

Hidden SSIDs

Android is not able to work properly with wifi networks using hidden SSIDs.

If your network is set to non-broadcast SSID, you will have to change it to broadcast.

Why does the widget update so slowly?

The widget updates less frequently than the status notification to save system resources.    Android best practices don't allow for widget updates faster than 1 minute. 

Why can't I change time between scans/checks?

These values can have a profound effect on battery life.  The timing has been balanced for maximum responsiveness with minimal battery use.
There is no benefit to changing them.

Why won't my Android 3.2+ device connect to a non-known open network using Wifi Fixer?

Google made changes to WifiConfiguration in Android 3.2 which causes networks created with a new WifiConfiguration object not to work properly due to missing fields.  I worked around the issue partially with Java reflection, but open networks fail on some builds of Android.   I will  fix this when Google responds to my bug report.
The bug report is here: Bug Report #21469
 

Why can't I add my network using Local Networks?

At this time Open/WPA/WPA2 is supported in Local Networks. You can use the Android settings app to connect.  The network will appear in Wifi Fixer under Known Networks.
