WP admin very slow at home

Guess I will have to be doing more of my posts on the road.  For some reason, now that I have switched my home broadband service, my access to my WP admin page has really slowed down.  The blog page itself still loads fine, but the admin page takes for ever.  What’s really odd is that the server my blog is on is on the local home network, so it’s not like it really has to go that far.  It might be some wierdness with the way that the ddns and cable work together.  Always something breaking.
