Wireless things have stopped working

[bcjames]

Hey all,

My e2011 Macbook Pro has suddenly developed an issue. As of yesterday, selected wireless things have stopped working. I have lost ability to print to a HP AirPrint printer, another printer connected to an airport express, iTunes streaming to hifi via airport express, and ps3 media server.

All the devices seem to work independently, just the mac now won't 'see' them. I've tried resetting the AE, and it allows me to set it up, solid green light, then a rescan won't find it. That still doesn't explain how I've lost the laser printer and the ps3.

Any ideas would be very much appreciated. Inability to print is really hampering my work! Would rolling back a time machine save potentially sort this?

Thanks!

I fixed it

I swapped the router downstairs. I'd tried everything in the study, just did that as a last resort. I don't know how it managed to lose certain services but the internet to all devices remain working, but it did. Or even that the AE wouldn't work without the router telling it stuff.

And now it works. And I can easily print stuff. Yay!
