Can’t upload images or publish while at Starbucks

This week I’ve been at Starbucks, using their t-mobile hotspot service, and trying to edit my blog.

It has worked from my home at other times, so the problem is only occurring when I’m logged on here at Starbucks.

When I try to create a new post, and upload an image, I go through the process of selecting the image and hitting upload, and then instead of the image appearing, the entire part of the page turns into a mini version of my home page (which is the redirect from a 404). If I try to save/publish, the same error sorta happens. The post isn’t saved, or published, I just end up at the main screen, a redirect from http://www.portigal.com/wp/wp-admin/post.php

Why won’t this work when I’m logged on here?

Thanks?!
