How can I add more memory to my iPad?

No.

Memory refers to RAM, and can't be increased.

I asume you mean storege space (like 16GB, 32GB, etc). It also can't be increased.

There are some wireless external hard drives that can be used with the iPad.

The Kingston Wi-Drive, which costs $50 for the 16 Gigabyte, and then $30 more for every 16 gigs more. It works by you turning it on and then accessing the files on it from an app that you download on your iDevice. You can access music, movies, and other stuff. No connections or anything, it works like a WiFi connection, you connect to it from the setting on the iPad under wireless networks.

Then there is the Seagate GoFlex, which some would recommend over the Wi-Drive. But this one costs $199 and had 500 Gigabytes of storage. It works the sameway as the Kingston: no wires, runs over its wireless connection. You can actually fit up to 300 HD movies on it.

Another option:

Expand your iPad's storage capacity with HyperDrive

Ok...TO SOLVE THIS ISSUE...Just reinstall the time Warner/Roadrunner App on your ipad and when u get to the question asks 'Do you want to install without SSL' say yes.

Did you mean to reply to a different question?

If you are referring to storage space on an iPad see the solution at the top of this posting.
