Buffalow WHR-HP-G54 Received Packet Errors very high

My setup is a Buffalo WHR-HP-G54 in AP router mode connected to a qwest dsl
modem.
(2) Trendnet TEW-429UB usb wireless adapters, one in a desktop, one in an
old laptop

With the v24 beta generic dd-wrt installed I'm getting extremely high and
incrementing wireless received (RX) errors. Here is a sample display after
20min or so of uptime:
Wireless Packet Info
Received (RX) 3% 829 OK, 28939 errors
Transmitted (TX) 100% 3049 OK, 11 errors

By disabling the two client cards one by one, I see that all the errors are
associated with the laptop, and these Received errors increment by exactly
31 with every Transmit packet. The client drivers are identical and
swapping the cards between the pc and laptop has no effect. The laptop is
close to the AP and the signal quality is 100%.
The laptop is an old Presario 900 with a usb1.1 port, winxp home, fully
patched.

The other clue is that with v23 (SP2) dd-wrt, the errors were so bad the
laptop would connect for maybe one minute out of 20 minutes. With v24 beta,
both clients connect immediately and stay connected (WPA2-PSK/AES in use,
G-only radio setting).

So, is there an adjustment in dd-wrt that I should be looking at, something
maybe that changed between v23 and v24? Or some issue with the laptop and
it's old usb1.1 ? Any comments/help appreciated very much!

That's an awfully large number of errors for just 2 minutes. More
specifically, that's
29000 errors / 120 seconds = 240 errors per second.
That's not a transmission or reception error but probably a bug
somewhere.

What exact version of v24 are you using?

Hmmm... maybe a bug in v24? See:

Try it this way and see what you get. I think (not sure) that your
results may be different. Try it on mine:

# ifconfig br0
br0 Link encap:Ethernet HWaddr 00:14:BF:B9:10:13
inet addr:192.168.1.1 Bcast:192.168.1.255 Mask:255.255.255.0
UP BROADCAST RUNNING ALLMULTI MULTICAST MTU:1500 Metric:1
RX packets:116822 errors:0 dropped:0 overruns:0 frame:0
TX packets:105783 errors:0 dropped:0 overruns:0 carrier:0
collisions:0 txqueuelen:0
RX bytes:14083918 (13.4 MiB) TX bytes:25569403 (24.3 MiB)

Which corresponds (roughly) to the [v23 SP3 07/21/07 std] status page:
Wireless Packet Info
Received (RX) 100% 9353 OK, no error
Transmitted (TX) 100% 43355 OK, 217 errors

Note the discrepancy in the number of tx errors. Sigh... another bug.

You really should post your question in the DD-WRT forums.
