My iPad Mini with iOS 6.1 will not connect to wifi at the office but iPhone 5 with iOS 6.1 will. Any ideas?

My iPad attempts to connect, and then returns the prompt "Unable to connect to the network"

We use IEEE 802.11b/g 2.4GHz

Linksys WRT54G v 2.2

I checked with our IT person, and the PW hasn't changed. As far as typing the PW in, I've even had others enter it on my iPad just to make sure. I also enter it slowly so I can see the characters before they disappear, and I do watch the letter case.

The router is not configured for MAC filtering.

Yes, the firmware is up to date. The IT person and I talked about purchasing a newer N router, which could possibly help.

Yes, all our Apple devices are running iOS 6.1 that was recently released.

I assume they all have the Broadcomm chip you reference.

BTW, thanks for your help today.

Thanks again for your help today.

I finally resolved this. I asked our IT person to read me the password for our wi-fi and when he did, it turns out one of the characters could either be a capital "I" or a lowercase "L". Turns out it was a lower case "L" and I was using a capital "I". The font that was used had no serifs, so you could interpret it two different ways. My iPad connected instantly once I logged in with the correct password.

I agree! I kept using a PW that was written down, and it wasn't until I asked him to READ it to me that we got the issue solved. Learned a great lesson here!
