Since I've a new Cisco router I've trouble browsing the web after resuming or starting my laptop. I did some debugging and it seems that I have a network connection, but that the DNS is failing for a while (say; more that 50 seconds).
You can see what I mean in my ping and nslookup output below. I tried this with Google Nameservers and my internet providers' DNS server, but both have the same result. After everything is fired-up for a while, everything works fine. (meaning, internet works, and all tried nameservers reply really fast).
Would be nice if someone has a clue on how to solve this issue.
Extra info: windows7, broadband connection, both wifi and cable connections share this problem.

Had the same issue. Here's what worked for me, behind a Cisco EPC3925 (cable ISP).
