God, thought i fixed it with a wireless-n router and it worked perfectly till now. I was loading videos on youtube in seconds with no buffering and fully loaded, and could stream even 1080hd vids on there and other sites no problem. Now the MBP is going slow again, like there's this lag when browsing, and I can't even watch youtube vids anymore unless their ****** 240p as anything else buffers every couple of seconds. It's not the internet, as like I've said before I have an pc in another room across the condo on the wireless network and its blazing fast browsing and watching/streaming videos. I've seen other post about this lately and really leading me to believe these $ MBP just suck on wireless networks, b/c I can be right next to my router and no changes... and my girlfriends cheap netbook can stream videos faster with no buffering then my expensive piece of aluminum. I saw someone else say enter this for DNS and I had already done that, so is something screwed up here?: 184.108.40.206 220.127.116.11 18.104.22.168 22.214.171.124 126.96.36.199 188.8.131.52 and Search Domains next to that says: domain hsd1.fl.comcast.net.
