The food's only meh, but the Bucktown Beanery at the corner of Damen and Webster has decent coffee, wi-fi and breakfast/lunch fare. I also work at the Map Room at Armitage/Hoyne from time to time. They open early, have wi-fi, it's quiet until the mid-afternoon bar crowd gets there and they serve great coffee. They only have breakfast food so if I'm there at lunchtime, I walk down to Las Asadas for lunch and bring it back, which the Map folks welcome. Both are closer to Wicker than Lakeview, but maybe that'll work for you.
And if food's important, listen to Jazzfood. Chief O'Neill's rocks.
