Internet problems, MBP slow again

[SurferMan]

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?:
208.67.222.222
208.67.220.220
4.2.2.1
4.2.2.2
8.8.8.8
8.8.4.4

and Search Domains next to that says: domain hsd1.fl.comcast.net.

Ok, even having Comcast send a refresher signal didn't work. What seemed to work, I changed DNS to only 4.2.2.1 and 4.2.2.2 and seems to be working ok, still buffers sometimes not as bad as before but that lag seems to be gone when browsing.

How come I have to always keep messing with DNS on this mbp??? I've never had to do this with any PC and even now, my PC is in the other room and with the door closed can still load/stream videos faster than my $ MBP even when I'm in the living room and the mbp is only feet away from the router?

However, DNS servers are not the only issue, the general consensus is that the MBP has poor reception due to the antenna being enclosed by the aluminum case. Your milage may vary on that, I have no problems anywhere in my house using the wireless - g bandwidth, not N - and that is a third-party wi-fi router provided by the optical fiber IPS here in Japan.
You should also try changing the channel being used, the default channel often is overloaded. Look at the router manual for instructions on how to do that. Or search here using Mroogle, http://mroogle.*************/
In the final analysis ethernet is faster if you can use it.

I couldn't use wireless-g, g worked perfect with my pc, but the MBP had horrible lag and couldn't stream any video, bought a N router and that helped .
