WRE54G Slow with WRT54G WPA

This is what I wrote to LinkSys support:

> I bought the WRE54G recently to extend my WRT54G (latest firmware as
of 8/8/05) wireless network in my home. It's throughput is extremely
slow when repeating primarily the download speed which is much slower
than the upload speed when WPA is enabled. I see nothing on your
website that addresses this problem though it has been discussed on the
Net. Should I return the the WRE54G to point of purchase? <

Is there anything I can do to fix this problem or should I return the
WRE54G?
