DNS configuration problem - really out of ideas.
I just moved to a new place and for past three days I kept getting the same error with DNS configuration trying to connect to the router provided in the house, wired or wireless. My computer can always connect to the router with only local access.
I'm running Windows Vista Home Premium (x32), which could connect to other networks just fine before I came to this new place. The router is a linksys WRT54G connected to a linksys RT41 BU. (I'm not sure why)
Here's my ipconfig /all with everything in Tcp/ipv4 set to automatic.

================================
On the status page of the WRT54G, internet IP address is 192.168.15.100, router Default Gateway is 192.168.15.1, DNS server is 192.168.15.1 which seems to be correctly configured by the RT41 BU DHCP.
However, on the status page of the RT41 BU, IP address,default gateway and DNS server are all 0.0.0.0 . I don't know much about networking, so I'm not sure how to take this.
The weird thing is I actually got internet access once right after I manually set my computer's DNS server to 192.168.1.1 yesterday. Unfortunately someone accidentally pulled the power on WRT54G and I never could replicate it after that.
I started to think maybe 192.168.15.1 is not the right DNS server. so I tried to ping some IP addresses and found out I couldn't connect to any external addresses. Is there a way to find out my DNS server address for sure?
I've also tried various methods mentioned on the internet. I've disabled Tcp/ipv6, removed 3rd party internet security software, changed the DhcpConnForceBroadcastFlag register. I've reseted winsock and tcp/ip and tried to manually input DNS address, including some public DNS addresses. Nothing seems to make any difference. (public DNS simply won't connect.)
If not for the one moment of internet access yesterday, I would put the doubt on the modem or my ISP. But it actually worked really well before someone pulled the power. Now, I don't know what to do anymore.
Any tips would be appreciated.
