ワイヤレスネットワークリストを1つのAndroidデバイスから別のAndroidデバイスにコピーする方法は？ -- wi-fi フィールド と settings フィールド と data-transfer フィールド android 関連 問題

I got a very long list of free hotspots and friends/family networks on my phone.

Recently I bought a tablet and I'm trying to find a way to copy the wireless manager list to this new device. Any idea how to do that? Both devices are rooted and running ICS.

As you are rooted: Wireless network data are stored in data/misc/wifi/wpa_supplicant.conf -- so you could basically copy all its network entries from one device and insert them on the other. The entries look like

network={     ssid="Telekom"     key_mgmt=NONE     priority=42 } 

An easier way would be using the App Wlan Backup & Recovery (root): Backup all entries on one device, and restore them on the other. As you can see in below screenshot, the tool can even send the backup by mail -- so transfer to the other device should be easy:

But reading the comments on this app suggests it does not always work as expected: Users even recommend to use the manual way I described above.

Another option is using Titanium Backup, and restore the Wifi data on the other device. I did that successfully a couple of times, also cross-device and cross-ROM.

Third option is offered by the app Wifi Passwords (about USD 1), which allows you to share networks.

You can do this without root permissions as its built into Android ICS. Just go to:

Settings -> Backup & Reset

Then when you setup the tablet you can restore all the Wi-Fi data from your phone when you sync from the same Google account.
