I'm using latitude D630 with ubuntu 9.10
Everytime if there are already some laptops connected to my home wireless, I cannot really connect to the network(although it keep says I do). In such case, I need to power cycle my wireless router. There are many possibilities but my windows on the same laptop have no such problem.

I tried to restart the network, disconnect and reconnect and so on. None of these worked. I think somehow the dynamic IP assignment related thing doesn't work. Anyone know how to fix this?

Thanks
