Can only connect 'halfway' over mobile hotspot
This may be an issue with your carrier's APN (DUN and IPv4 protocols).

As a workaround, try changing the APN type to DUN:


On your phone, go to Settings &gt;&gt; More &gt;&gt; Cellular networks &gt;&gt; Access point names
Tap the entry for your carrier.
Scroll down to APN Type and add ,dun at the end (so the it should say default,supl,mms,dun).
Ensure the APN Protocol and APN roaming protocol are set to IPV4
Save your settings.
Restart the mobile hotspot.
Disconnect and re-connect to the hotspot from your laptop.
