I regularily stay at the 4 points in San Rafael. They do in fact have high speed wireless internet in the guest rooms, it is free. You simply need to request the username/password from the front desk. I believe they actually had it turned on about a month ago(It was turned on during my last stay).
We stayed at the San Rafael Four Points last month (April) and they had pretty good clocking hi-speed Wi-Fi throughout the property and in guestrooms. As the above poster mentions, they should give you a little business card type thing in your key jacket at check-in, with a unique username and password to get through the entry portal.
