I don't know if I'm the only one, but do SR MBPs have weaker wireless cards than the old one? Or maybe my router is just dying. Anyhow my router is only about a month old, it's a linksys, and with my old MBP I could get about 6 Mbps anywhere in my house. Now only one room down I only usually get between 2 and 4 bars of connection, which is driving me nuts. The internet is also abit choppy, works well then all of a sudden stalls and won't load stuff. Then it starts working well again after 5 seconds or so. And so on. Could this be a defective wireless card?
