I just installed a new time capsule today. It's replacing an old Linksys wireless G-band router that has worked great for years. I put the Time Capsule in the same place in my entertainment center as my old router. It's right next to the cable modem. The entertainment center has some frosted glass sliding doors that hide the electronics. Here's the weirdness: When the frosted glass door in front of the router is open, I get around 25 Mbps download per Speedtest. But when I close the door, I get 1-6 Mbps. Obviously the glass is the issue, but I have no idea why. The old Linksys router did just fine for years. Any ideas of what could be going on with the TC and how I can get reliable wireless speeds without leaving the entertainment center open? Thanks!
