Ethernet works, Wirelss doesn't

bjeffers83 · Oct 26, 2013

I am trying to fix a friend's laptop, and the problem is the wireless doesn't access the internet. I will need help as I only know hardware and am a rookie to troubleshooting or software. That being said, I did ipconfig/all and ping. I don't know what to look for, but I saw that the ping hit the router, but did not hit a webpage. This is on wireless. With ethernet, the connection is fine, in fact I am writing this on the laptop in question. What steps can I take to understanding why the wireless has issues? It worked fine a week ago.

Also this problem is on a network in which others can connect just fine, and also tried on several different networks.

I did a windows troubleshoot. It says something about a DNS and is either incorrect or doesn't exist.

The ipconfig/all tells you all the details, like if dhcp is activated (should be), the gateway and the DNS. Gateway and DNS typically is set to the router address.

ipconfig/all

pings

Sorry, bit there is no additional info in your last post. Did you try to post the ipconfig output?

bjeffers83 · Oct 27, 2013

I posted a picture?

I don't see a picture. Might be blocked by my add blocker, but I don't think so.

Hi, the only thing I see, maybe it's the problem is your DNS Servers is 192.168.1.253 and your Default Gateway is 192.168.1.254.
On mine they are the same.

Thanks, I will try that on Monday and hope for a fix.

Different PC and now I see the pictures! I have to check my add blocker! As the ping statistic tells us and jarotech already mentioned, the DNS server address is wrong! That's why ping can't find the IP address for yahoo.com. The ipconfig says autoconfig=on, so the gateway and dns setting should come from the router with the dynamic IP address and it should all be set to the routers address. Another strange thing is the lease time: Lease Expires should be after Lease Obtained. That's also a setting in the DHCP section of the router.

bjeffers83 · Oct 28, 2013

Well, the laptop is set up to be on auto, so the problems are within the router you think?

bjeffers83 :

The router has a DHCP section / menu, where you can enter a DNS- and Gateway address. The router will deliver this with a new IP address. It looks to me, like someone mis-configured this somehow.

bjeffers83 · Oct 28, 2013

What do you mean about lease time? Expires is one hour afterwards.

bjeffers83 :

Sorry, my fault! (The am/pm thing sometimes confuses me, because I'm on 24h) Nevertheless, one day lease time would be better.

You can change your DNS for the Google Public DNS. You use the IP addresses 8.8.8.8 and 8.8.4.4 for your DNS servers.
