Every once in a while, my wife's laptop will connect with an IP address starting with 169.xxx.xxx.xxx instead of the usual 192.168.0.xxx. When this happens, her network connection doesn't work. Weird thing is, when I go into the router GUI, it shows an IP address of 192.168.0.xxx assigned to her laptop...completely different that what her computer shows. Releasing/renewing doesn't help. So far I've been able to temporarily fix it by just changes channels, after which the laptop connect properly, but after 1-2 weeks the problem returns. I have firmware v1.9. Her laptop is a Dell Inspiron 6000 running Windows XP Pro.
