Devil, I will try to find you a detailed step by step. Btw what version do you have of wimowifirouter? I use .91 which is the free version, what I did was install the "ICS" tweak/hack that you can on TP essentials stickied uptop, then created an "ad-hoc" connection under wi-fi and that was it. I launch wifi/winmo and boom connect the laptop to TP..
this is something i just pulled , i didnt watch that video, do a serach and u ll find a step by step
