Weird wireless router problem

[afeasfaerw23231233]

While my bittorrent server is working, my notebook cannot connect to the wireless router. The message from the router says it is because of wrong WPA key. Once I switch of deluge the notebook can connect immediately. However the traffic of bittorent is not hight at all -- there are only under 10 downloadings and uploadings altogether. The speed is limited to 50Kb/s and the total number of connections is under 50.

Does anybody have a similar problem?

EDIT: Once the wireless has been established successfully, deluge can be switched on again and the wireless connection never drops even the traffic reaches 10mbps (which is the maximum bandwidth provided by the ISP).

Strange indeed. What brand & model number is your router?

[afeasfaerw23231233]

D-link DI-524
It has the latest firmware flashed.

Perhaps the cpu of the router was too busy that it mistaked the WPA key as invalid?

Here's the extract of dmesg

[ 92.740014] wlan0: associate with AP 00:19:5b:df:63:da

And from the internet I found the definition of the status codes

code 17 = Association denied because AP is unable to handle additional associated stations?
That means the router is too busy (because of bittorrenting?) to handle the wireless association?

I tried flash DD-WRT on it but the router only has 4MB of memory so it is not possible.
What a crappy router!

Any idea?
