Airport Express doesn't allow to join ...

Hi there --

I am experiencing a problem I've not encountered before with my Airport Express, which is now about 4 years old. I will be on my network (WPA/WPA2 Personal), connected to the internet, no problems at all. Then I leave home, bring my MBPro with me, use my MBPro successfully on another network (at school, at a cafe, at a friend's home). I come back to my own network, and suddenly my network appears in the list of available networks, but I cannot connect to it either automatically or manually (I get a message that it has timed out). The same is true if I try to connect with my iPhone, which has my home network "remembered."

When I look at the Airport Express, the light is green and all appears fine. Even if I completely restart my MBPro or even shut-down and restart, the same problem. Opening Airport Utility, the utility tells me that no Apple Wireless Devices can be found, no matter how many times I hit Rescan.

The only solution is to unplug the Airport Express (again, with green light, looking "fine") and plug it back in again -- but even so, sometimes I must do this 3 or 4 times before it allows my computer or iPhone to connect. And, when that happens, at the same time, of course Airport Utility can locate it and reports that all is well.

I have Airport Utility set up to automatically check for firmware updates daily, but none have been reported. I believe the firmware is up-to-date (it is using version 6.3 and this is an Airport Express that is 802.11g/b compatible).

Anyone have any suggestions? it is getting very tiresome to go through this unplug-and-test routine two and three times daily.

Thanks,
A
