Is this happening with only one access point and seems to work good with others? A WiFi connection has two hardware devices which can be causing this. Either your Mac or an access point such as a router for example, or both. Did this occur after an OS X update? If you have problem with just one access point or just very few of many, we would like to know the name of one of them. Some routers just don't play well with Mac for some reason and at least one access point doesn't play sell with a particular MacBook but works fine with other MacBooks. An attempt to fix poor WiFi connections often involves changing the channel. If you have control over the access point you could try to change channel and aim for the ones that got least traffic from others. Or test them one by one, they are not too many. And a controll over the access point might mean you couldtry to update its firmware. But if it is a known Mac uncompabillity with your access point you better get another one. Another informative trst would be to bring another Mac to see what happens? // John_______________________________________________ MacOSX-talk mailing list [email protected] http://www.omnigroup.com/mailman/listinfo/macosx-talk
