No, this is only for Firefox. It tweaks the web browsing.
If you want to tweak your internet connection.. that's a separate issue. You'd have to make some registry value changes and maybe download a 3rd party program which helps also.
I'm very good with that. I used to be an admin at
SpeedGuide.net :: Your Guide to Broadband
check their forums out and ask there.. but I don't know if you'll get in trouble for tweaking your connection at work..
