iPhone 4 loses WiFi range. Why?

[DeusxMac]

My iPhone 4 recently lost its ability to pick up the signal from our home Airport Express (which extends the range of the home Airport Extreme.) :banghead:

It picks up the Airport Extreme just fine when close enough to it, but appears to not "see" the Airport Express when out of range of the Extreme.

An iPad 4 and a MacBook located at the exact same location, close the the Express but far from the Extreme, will get a strong signal, but the iPhone cannot get much more than one bar, and usually not even that.

This is a new symptom (a couple of weeks now,) so I'm wondering if it's something that's failed (or weakened) in the iPhone itself, or if there's some iPhone setting that can get hosed and cause this problems?

Thoughts and suggestions appreciated.

Yes. 6.0.1

Try turning off WiFi on the phone, then stand as close as you can to the Express to try and force it to connect to the Express rather than the Extreme. This usually helps when my iPad seems to not want to see my Express, which I am using just as you are.

Reboot your iPhone.

Reboot all your network devices (if a reboot of the phone doesn't do the trick).
