Hi All, My personal MacBookPro is a model 1,1 from late 2006. It supports 802.11g and I almost never have problems with wireless networks. My work laptop is a model 4,1 which supports 802.11n. It as well never has issues with wireless networks. My in-laws have a Dlink wireless router that does not like my personal mac, or I should say my personal mac doesn't like it. What seems to happen is I get an incredibly slow connection speed. For instance certain media-rich sites never get loaded, everything is sluggish, even if I'm sitting right next to the router. My work laptop on the other hand works like a charm, no problems at all. I'm curious if anyone knows if the difference in 802.11 protocol support is contributing to this? My wife's mac also supports 802.11n and she seems to have issues too. Unfortunately I can't seem to log into the admin page of this router, it's probably configured to use a non-default IP, I'm trying to get in touch with my in-law's computer guy on that. Any ideas would be greatly appreciated, this is little bit of a mystery.
