Hi, The name of the login screen and the name on the network are not the same.
You can modify the name of the login interface in the /www/src/temple/login/index.html file as following,
<p class=" text-center active clsDeviceSSID">
GL-{{t(productName)}}
</p>
And you can edit the /etc/config/network file to modify its hostname on the network as follow command,
uci set network.wan.hostname=‘GL-AR750S-33f’
uci set network.wwan.hostname=‘GL-AR750S-33f’
uci set system.@system[0].hostname=‘GL-AR750S-33f’
uci set samba.@samba[0].name=‘GL-AR750S-33f’
uci commit network
uci commit system
uci commit samba
Thanks.
