OSX not remembering wireless network...

[R.Youden]

I have just changed my wireless router from an Airport Express to the standard router supplied by my ISP. Now every time I start or wake my laptop it presents me with a list of networks and I have to manually select it. If I go into System Preferences my new wireless network is at the top of the Preferred Networks list. Any ideas...

Which version of OS X are you using? And...what's the make, etc of the router?

It sounds more like an issue with the new router than OS X, since there weren't any issues with Airport Express.
