Q: Cannot communicate with primary DNS server (Vista) This thread is locked from future replies

Hello fellow geeks. I might need some help from you... So yesterday I went on a vacation from Portugal to Angola (Africa) and I'm staying in my cousin's house. The first day I spent here I asked my cousin for the router's password and the wireless worked pretty well. The next morning I woke up and tried to connect to the internet (via wireless) but I couldn't. All the other PC's in the house could, exept mine. I tried using the Ethernet cable and it worked perfectly, but I really need to use wireless. I tried to troubleshoot the problem and this is what Windows said: "Cannot communicate with primary DNS server". I've surfed the entire internet and found 1000 solutions, but none worked out for me. That is the reason I'm writing this. I'll give you all the info I possibly can, unless you ask me for more:

Router: Atheros AR5007 802.11b/11 WiFi Adapter

CMD ipconfig /all command info: (It was in portuguese I tried to use google translator to translate it to english, I'm not sure if its good or not but if you don't understand something, please tell me)

e. Under General tab look under the "this connection uses the following items"

· Click on Internet Protocol (TCP/IP)
