2 MBPs and a DLink wireless router

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.

thanks for the link to IPScanner, that's a useful tool aside from this issue. I actually found out the router is a G router, not an N, so both laptops should theoretically work fine.

thanks for the reply, I'm actually running tiger (10.4.11) and unfortunately this has been a long standing problem spanning many versions of my OS that's been driving me insane and want to get to the bottom of. So far I've tested 3 laptops, 2 MBPs with the problems described in my original post, in addition I've tried a MacBook also running tiger but supporting 802.11n, it is having the same problems. My work MBP that doesn't have problems is running Leopard, perhaps it is an OS issue? Thanks again.
