Hello everyone,

Recently, I moved to a new rental house and brought my desktop computer with me. Unfortunately, this rental house does not allow me the capability to have a wired connection. So, I bought the ASUS PCE-N15 Wireless Adapter.

After installation, for some reason, I could connect to a wireless network but I couldn't browse the internet. After diagnosing the problem, every diagnostic told me that I am connected to the Internet but the DNS Servers are not responding. I tried to change the DNS servers from Comcast (my ISP) DNS to the public google DNS servers and also tried OpenDNS. None of these solved the problem. Sometimes, for a minute or two, I'm able to browse the internet, but then I won't be able to later.

Any help would be much appreciated. Thank you.

It sounds like an issue either with the wireless or your wireless card.

Try pinging the router both when the internet is up and when it's down. If you are able to ping the router when the internet is down then the router is the issue. If you cannot ping when the internet is down then you have an issue withe the wireless card.

How to ping.

windows key + R
type cmd in the text box
In the command line type ipconfig /all
Look for default gateway, write the ip down.
in the command line, type ping and then the ip address.

Can other devices connect and surf without issues?

So your manually setting DNS settings for your adapter and still nothing?

Most likely the router or your adapter as said above.

I guess there is No way for you to get access into the router to dig dealer?

I could not ping the internet when it was down, but I could when the internet was up. So I guess something is wrong with the card? Should I try a re-installation? Get a new one? (If I do get a new one, would a USB adapter be okay? The installation seems easier).

It may be an issue with connectivity - there could be interference such as cordless phones, microwave ovens, other electronics, etc.....

I'm not so sure. There are probably about 10 wireless devices in the house other than my desktop that work completely fine with the Wifi.

What is the distance between the computer and the router, and are there major obstructions (walls, floors, electronics, etc.) between them?

I'm on the same floor as the router, and the house is designed with an open floor plan so there aren't any walls in the way. The computer is probably about 50 feet or so from the router. I don't think electrical interference is a problem, either.

Considering all the factors, it looks like the wireless adapter is to blame. Try uninstalling and re installing the drivers.

The only other solution is to get a different adapter. If possible, try and get an adapter with an external antenna. Make sure to return the old adapter.
