I have a Wi-Fi connection problem with an Android device. So, a Samsung Galaxy Tab 2.0 (7") could not connect to:
Security-Enabled Computer-to-Computer network ( over Wi-Fi )
Network Authentication: Open
Data Encryption: WEP
Note: The device doesn't see that type of network!
However, it could connect to:
Security-enabled wireless network
Security-enabled wireless network (WPA)
Security-enabled wireless network (WPA2)
Unsecured wireless network
Note: Verified in many places like cafees, airports, University of Calgary campus, etc.
Any ideas, tips or suggestions? Thank you in advance.
[ Summary as of December 17th, 2012 ]
A test with a MacBook ( Mac OS X v10.7.5 ) notebook was finally done and it successfully detected and connected to our Security-Enabled Computer-to-Computer network ( over Wi-Fi / Open / WEP ) created between several computers with Windows XP and Windows 7 OSs. The test was completed in less than 2 minutes without any issues and problems.
[ Summary as of December 4th, 2012 ]
- An update from Samsung for Android OS v4.0.4 ICS was recently installed on the tablet
- Wi-Fi Advanced Configuration Editor was installed on the tablet
The application allows to see and edit advanced settings of a Wi-Fi network and it is
downloaded from: market.android.com/details?id=org.marcus905.wifi.ace
- Linksys 'Compact Wireless-G USB Network' adapters are used on some desktop computers with Windows XP
- The following advanced settings of the 'Compact Wireless-G USB Network' adapter:
are considered as the most important and were modified many times during many tests
Note 1: NetworkType is set to 802.11 Ad Hoc
Note 2: Widest possible ranges for channels were selected:
CountryRegion ( Country Region 11G ) - #5 Channel ( 1 - 14 )
CountryRegionABand ( Country Region 11A ) - #7 Channel ( 36 - 165 )
- Microsoft Network Monitor v3.4 was used on some desktop computers with Windows XP
- A Wi-Fi Signal Strength is always 'Excellent'
- A workaround based on a Bluetooth connection was considered, it works and tested. However, a transmittion speed and a distance between tablets and computers are two significant constraints:
A transmittion speed limitation of the Bluetooth connection - it takes too long to transmit large data files
A distance limitation of the Bluetooth connection - a tablet could be away ( many meters ) from a computer with Windows platform
- That computer could be considered as a 'Bluetooth Server'
- Some number of Bluetooth adapters are also needed
