Yeah, the Shannon exchange doesn't seem to be over-subscribed, like some other DSL enabled exchanges throughout the country. I think Shannon has two exchanges too. One near the Town Center, by the old ESB store and I think there's also one by the Airport. I reckon you're connected to the red-brick one by the ESB building though.
Also, you're well right to steer clear of Wireless. It's too erratic. If your DSL speeds and response times are consistent and peaking maximum most of the time, then you're better off sticking with it.
Oh, and welcome.
