Slow download speeds only on Bootcamp partition with Time Capsule

I recently switched from a Netgear router to an older 3TB Time Capsule (Model A1409). Everything works fine on the Mac side with download speeds around 25 Mbps, but when I switch to the Windows 7 partition it drops to around 1 Mbps or less. I'm running Bootcamp 5.0 and to my knowledge have all the necessary drivers.

My roommates running Windows 7 on their PC's aren't experiencing this problem. All my other devices are also working correctly.

Any ideas on how to fix this?
