First thing I saw on my MacBook this morning was the following window.

I use wpa2 with a complex pass code. I'm the only one with a Mac in the building (6-plex). I have an older iBook but it's not connected. The message says to try connecting again later but I never lost the signal. I'm confused...

Try renewing your dhcp lease. System Prefs > Network > Airport > Advanced > TCP/IP, Renew DHCP Lease.

If you're concerned about someone else using it, log into your router and examine its client table. It should list any other connected devices with their IP addresses.

Thanks for that Cold Warrior. After receiving that message, my connection was very slow (3 seconds for Google page), so I turned my modem and router off, and basically reset everything, including a restart.

I just went into my router and noticed that I had no encryption at all!! How can that be? I changed my pass code about a month ago. So I just put in a new password and I'll wait and see what's going to happen. Maybe it's time for a new router? My D-link is about 6 years old.

Btw, I couldn't find the Client Table that you mentioned. But I will renew my DHCP lease momentarily.

Why is my dhcp lease button grayed out? It says I'm configured but I don't seem to have access.

Question:

When configuring a wireless router, is it best to do it hard-wired, rather than wireless? Or does it make any difference?

No difference.

"Why is my dhcp lease button grayed out? It says I'm configured but I don't seem to have access. "

Are you using DHCP and are your System Preferences unlocked (padlock in the lower lefthand corner)?

Actually a lot of wireless routers will give you problems if you make changes wirelessly. Often, such changes disconnect you, so you're left with an "OK" window waiting for a response, and everything is sort of in limbo. I would recommend ALWAYS using a wired connection to alter configurations.

Thanks. I completely missed it.

True, but if you know what the changes are that you've made and can rearrange your network appropriately to reconnect with the router after the change, you can avoid moving and wiring up your router just to reconfigure it.

I just don't envision having a totally wireless network, so that solves that as an issue.
