I have recently purchased Huawei wifi wingle E8231 from retailors.I have done a firmware upadate from internet.Now,under Network Settings,the selection 3G only is missing and the wingle automatically selects 2g with good signal strength even if 3g is present with comparatively low signal strength.I am attaching herewith the current device info from the device webui:
Device name: E8231
IMEI: 862869028858970
IMSI : 404781100777401
Hardware version: CH1E8231SM
Software version: 22.618.11.02.910
Web UI version: 17.100.05.03.910
LAN MAC address: 90:67:1C:FD:E6:20
WAN IP Address: 100.119.104.190
Please resolve the issue and provide the "3G only" option by a fresh update. Otherwise this purchase is a waste for me.
