No solution with tables and phones, make a big problem in pfsense Lan interface

[abedallah.m89]

Welcome all members and developers of pfsense

I have been faced a big problem with phones in my pfsense firewall , i have 12mbps adsl , and i configure queu HFSC on LAN interface,

the problem occure when any andorid phone be far from access point devices and the signal be weak and disconnect ,

after moments  the LAN interface be nonresponse  .(see the picture attached ).

I try many many ways to prevent that , but i fail , the only solution for this problem is manually shutdown and start again the switch conneted to LAN interface .
Note that : the problem is disappear when phone and tablet that make a problem connect again.

i try to flush arp, flush state table , enable and disable LAN interface and make synproxy state as state type of rules but no solution.

i use packet capture to analysis the  traffic  but i can't concluion any thing

so pls , any idea to solve this problem
I find a way to solve this problem by disable LAN interface and enable it again from webgui interface LAN page … But how can disable it from shell??? ....
(Ifconfig bge0 down and ifconfig bge0 up) not effectiveness .
I want command act link webgui enable check button .
