over the weekend our wireless router needed resetting-nothing I haven't had to do before. But ever since, my MBP (running 10.5.5) takes a long pause before loading pages. My old iBook (running 10.4) has no such problems. This is the case whether I'm using the aircard or connected via ethernet cable. When i tried accessing my website and the control panel for the website (on the same server i imagine) and MBP never finds the server, regardless of browser. Again my ibook has no such problem, even though it's going through the same router and ip. The tech at the website host said: As you are able to access the site via the same public Ip from another machine, the issue is definitely due to some network issues in your local machine. Please try disabling the firewall of your machine. I've poured through the preferences panels for security and sharing and can find nothing blocked or set weird. I've accessed my site from this mac on this router before so I'm clueless why that server (and so far only that server) is inaccessible. Also tried accessing web through different wireless signal miles from home and could never access anything, regardless of which signals I tried. Any clues?
