when i go out sometimes i do this and i have no problem connecting with my hotspot i also have both steam and non steam copys of RW and both work, so if you cannot connect with your steam copy there will be a high chance your non steam copy wont connect too oO maybe the mob network is poor or over used in your area, this could cause dropouts and disconnections, does your provider own the tower or do they piggy back off another provider, this too can cause problems as if they piggy back you connection is less prioritized and less stable.
