  • 1.  Samsung tablets dropping wireless connection

    Posted Jun 07, 2017 09:57 AM

    My client has Samsung SM-T230NU running Android 4.42.  The Wi-Fi network is comprised of Aruba IAP 205s running FW 6.4.2.6-4.1.1.13_54918.  The Samsung tablets frequently lose connection with the Arubas while other devices laptops, Apple devices do not.  Any ideas what may be causing this and what the resolution may be?  Thanks!

    Is this an open, psk or 802.1x SSID?

    What kind of access points are these?

    Do you have "broadcast filter arp" enabled on your SSIDs under advanced?

    How often do they drop?  Do they drop while roaming or stationary?

    -41 in total spread over 3 floors.

    -There are 2 fairly close to the area where the Samsung tablets are experiencing the issues

    RF utilization is very low.  Is there anything I should be looking for?  Is there anyway we can chat live about these issues?  Thanks

    There is no facility for chat on this forum.  You would typically open a case with TAC.
