Hi, I’m a member of ptawug(www.ptawug.co.za), a open wireless network in a city for people to share data and game in the evenings. I’m a real noob at this mikrotik thing, but I was wondering what I needed to do and set up to do the following:
Currenty I have one wlan interface connected to one of ptawug’s AP’s called highsites. They have 51 highsites. What if I added a second wlan interface in my Routerboard and connected to another highsite as a ‘second’ user? What will I need to do to ‘combine’ these 2 links do double speed or durability so that my PC uses both links at the same time? 
Reply with help will greatly be appreciated…
