D-link modem and Airport Express

[bollard]

My ADSL modem the D-Link DSL-300T is not compatible with the latest version of Airport Express 6.2.0. So I've had to downgrade to 6.1.1. and it work's fine.
I've since done a software upgrade which I didn't realise would update 6.1.1 so downgraded again. My question is how do I update my software without upgrading Airport Express and how can I find out if any update to Airport Express will work with this modem.

My question is how do I update my software without upgrading Airport Express...

Can't you just deselect it from the Software Updater window next time? There's an Ignore Update command in the Update menu too.

...and how can I find out if any update to Airport Express will work with this modem.

Ask around here or trial-and-error I suppose.

Sorry I can't be more helpful.
