DI-524UP wireless problem !

[CheeSen]

My situation like this :

First, i have a wireless router which is DI-524UP and has been set for wireless access point to surf the internet. When i am using the wireless alone in the house , it is smoothly and perfectly be used.

The problem is, when my brother back and start his computer to use wireless, my computer wireless disconnect and can not detect the SSID some more. When my bro shut down his computer , my computer works again and detect back the SSID =.= so what's the problem ??
of course my bro pc is nearer than my pc to the wireless router.

Hm.. Have you talked to your brother about this? Any chance that he is sabotaging your connection to get faster access himself?

make sure all systems use DHCP to acquire the IP config.

if your brother has a static address AND it just happens to be the one you got
from the connection (eg 192.168.0.2), then your brother creates an IP address
conflict and one or the other system will get disconnected. Usually, it is the LAST
system connected however.
