Hello, I am having WiFi problems. As I'm typing in this on my phone I'll try to keep it short (and please forgive any errors). I have Comcast at my house and, having recently made the decision to return to school full time, use xfinitywifi hotspots when at my apartment at school (basically every Comcast router broadcasts a second public network other Comcast customers can use when traveling or whatever). About a week ago, I lost internet access at the hotspot near my apartment. I can connect to the router just fine, just no internet. Despite 24 calls to Comcast and counting, I have gotten no where. I find their incompetance astounding yet, somehow, not surprising. But that's a subject for another time. I have confirmed that I have internet access at any other xfinitywifi hotspot. I have also confirmed that there are other hotspots in range of my apartment. The problem I have is they all share the same SSID, and OSX insists on connecting to the one with the best singal strength... Which happens to be the ONLY one that doesn't work. Is there a way I can choose which router to connect to based on MAC ID? As the routers operate on different channels, can I lock OSX to a single WiFi channel? Any other suggestions that don't end with me paying 2 cable bills? Thanks!
