No secure your network in WPA if possible. Your network is so insecure with WEP. I can hack into it within 30 seconds if needed. (As a Network Administrator its my job to know how to do these things so I don't condone hacking into your neighbors wireless.) Google WEP hacking for more details or you can see the videos on youtube. Your network is soooo vulnerable.
And a number of the wireless bridges don't support WPA. Unless you have to use wireless for a specific reason, it tends to add a lot more headache than benefit.
Wireless is great on a computer where you can see if you lose signal. A bridge doesn't tell you that you're dropping back to a much slower speed and that's why your download is struggling.
As a side note, I worked as a network analyst for years. I never connect embedded devices (like the HR2x) to a network connection that can fail (like wireless). You can buy 2 $30 homeplug devices (from DirecTV even) and have much more reliability than a $40-$90 wireless bridge. That comes with zero configuration.
