Doing all of this will make you stand out more. Better to blend in with the general public a bit more.

Buy a cheap (preferably stolen) smartphone on craigslist and throw away the SIM card. Preferably this should be a phone with a removable battery. Walk to a bus stop that is near to a starbucks and jump onto their wifi with the phone, pretending to wait for the bus. After a while, walk away. Since you are outside during the entire process you can do this during winter and bundle up, concealing your identity while not looking suspicious.

Using a laptop at a busstop would draw attention. Using a cantenna anywhere not private would also draw attention. Getting a private place to use the cantenna is prone to problems (you could aim it out your apartment window, but that ties you to a location. You could park a van nearby, but that is suspicious). You can easily dispose of the smartphone later; just microwave it then go for a nature walk and throw it in the river.
