I have a bit of a strange setup for a particular area. Remote AP with an uplink feeding 3 Campus APs that home back to a main site. The link between them is a 50mb/10mb connection from Time Warner. The CAPs function properly for the most case, routing traffic back to the main campus controller, and treating users like they are regular campus users, however mobile devices for some reason can not get speeds faster then ~1Mbps. Laptops are able to achieve 40Mbps by comparison. It is such a strage setup that it is hard to know where to begin. I am wondering if it could be a n MTU issue. Any theorys would be great, even just a guess :)
