My WL-138G seems to disconnect on pages with lots of large pictures. After it disconnects, I need to manually reconnect to establish a connection with my AP. (which is a WL-500G)
As soon as I get a change to load a few large pictures into the cache, and *then* reload the page, my WL-138G stays connected.

Here's an example page:

At first I though that the sudden high transfer rates would break the connection. I tested this by downloading a few large files from highspeed mirrors, but I was unable to reproduce the problem.
So my guess would be that the problem is with the amount of connections made in a short period of time.
Strangely enough, I can run eMule (which is sure to open quite a lot of connections in the first few minutes) without any problems.

Switching off the frame bursting mode on the AP didn't help.

Did anyone else experience this as well?
Will ASUS bring out a new driver or control center to address these problems?

Specs:
Windows XP, SP1 with latest updates (except for SP2)
ASUS Driver v2.0.3.19
ASUS Control Center v2.1.7.4
ASUS WL-500G, firmware v1.7.5.9-5
