In my apartment building there is no access to internet, so having a GSM stick is my only option. I would like to know some way to let my ps3 share the connection somehow, at least for the game updates. I run on firmware.
Connect the PS3 and the laptop with an ethernet cable. Then go to laptops control panel, network and sharing center, click on change adapter settings on the left, right click on the GSM network adapter, press properties. Finally, go to sharing tab and enable network sharing.
