So I got a new router from my ISP, so I removed my old router and just use theirs in stead. Now, on my iMac when Im streaming video (live.twit.tv to be exact) sometimes the video doesn't play as well. As if I dont have sufficient bandwidth. It always worked fine and my ISP promised me that my internet speeds are increased, so i should have even more bandwidth than i had before. However, I didn't have this problem before and now I do. Also, since I installed this new router sometimes pages load very fast in Chrome and sometimes it says 'Sending request... ' for ages and nothing happens. I try to load the page again and suddenly it works fine. So that might be a problem with the new router, I think Recently I noticed that most of the time when the video is forced to re-buffer again , my iMac is not connected to wifi. Sometimes it will connect again by itself and sometimes I have to tell it to connect to my Wifi again. So , is this my internet or something wrong with my iMac? Im currently streaming video on my MacBook pro which is just a few inches from my iMac and I haven't seen this problem yet. Maybe their is something wrong with the Wi-Fi radio in my iMac? Hopefully you guys can help me out on this one.
