"connection timed out" problem w/ITunes/Ipad apps (WiFi, Internet)

[loves2read]

I have desktop computer with Windows 7--Gateway hard drive
I have an IPhone 4 and recently got an IPad--
I have a WiFI connection to ATT Uverse Internet--

I can't download updates to my Iphone or download apps via the ITune on my hard drive
I get message after a few seconds saying my "connection has timed out"
I am having no trouble currently getting on the Internet or surfing
I downloaded a Windows update yesterday w/o any problems

my ITunes says that the "connectivity" with my OS is with a Windows program but not Windows 7--althought that is what I bought when I bought this hard drive about a year ago and have downloaded updates to it periodically

I got ITunes when i got my IPhone--around April or so--
never used it before--don't have Ipod even now...

I had someone at the ATT store set up my IPad--not at Apple or Best Buy (where my husband got it) because we use ATT not Verizon
she did not ask anything about what OS system I had...

any suggestions that someone who is as IT challenged (as I am) can follow would be appreciated--

It sounds like you have a firewall that is blocking the application. Check your security settings.

that was the problem
had a call with Apple help line
guy said to turn off the security program I was using
did and hooked up
did the downloads and then rebooted to connect the security program

will just have to do that next time need to download via hard drive

If you open the security program you can add iTunes to a whitelist so it can get through in the future.
