Question

Laptop connects to wireless network but not internet?

by lowen92 / September 10, 2011 10:44 PM PDT

My laptop does not connect to the internet on the wireless networks in my flat. It will connect to the network, but will not have internet access. There are several unsecured wireless networks available run by the flat and I can't connect to the internet on any of them, whereas other members of the flats and my flatmates are able to. This suggests there is not a problem as such with the router, turning it off and on again has already been attempted. When I moved in, the man in charge of maintaining/organising etc the flats took my MAC address and allowed my laptop access. Yet I cannot connect to the internet. I went to my uni's library and connected to the internet no problem. I have tried turning off my internet security, looking at the properties of the wireless connection and attempting to edit settings (changing them back again afterwards), and nothing seems to be working. I have taken a printscreen of my network status here <a href="http://i53.tinypic.com/o6hgs7.jpg" target="_blank"><font color="#0044dc">http://i53.tinypic.com/o6hgs7.jpg</font></a> in case it sheds some light on the problem. Thanks in advance for your help!

Does it connect elsewhere (say, any free WiFi, school, work, friends, family)?
And can you post the output of ipconfig?

Yes, like I said it connected to the wireless at the university library.
I will post that next time I have internet access after viewing my laptop (I am using someone elses at the moment)

If they use WEP, it's a common issue.

The machine will look connected but not work. Have someone else put in the passcode.

MAC

If it has never connected here, verify with the mgr that the MAC address he entered is correct.
Do an IPCONFIG in a CMD window to verify u gave him the correct # for the wireless adapter.

If u do that now it will probably show a 169.xxx.xxx.xxx address, which means u are not getting an IP from the router. U should be getting a 192.168.xxx.xxx. Do u see a default gateway listed? if so it is definitely talking to the router.

MAC address blocking or lack of a key will do that. Since there is no key required it is the MAC address --- unless:

it is the W7 trick, which seems to have been fixed, so make sure u have all the updates, but this is not the symptom of that.

Sorry, did you login as a new name?

Or is this a reply to me? I can't tell.

The guy has double checked that the MAC address he entered is correct, and came to check my laptop and did the IPCONFIG thing and confirmed that I had given him the correct information.
I will take a look at the 169/192.168 addressses once I get back to my laptop, and post the results here.

What do you mean have someone else put in the passcode? The guy in charge of sorting out internet was the one who entered the MAC addresss, which he has double checked was correct, and there's not really anyone else on site who would have more knowledge of the system than him. I was however considering calling in a technician or something if the problem persisted and I couldn't find a solution online.

The Mac address is only proven correct ...
by Kees_B Forum moderator / September 11, 2011 10:03 PM PDT
In reply to: Bob

if it works, not if it's merely doublechecked.

Same for the encryption and the password. That should be the only variables that can be involved if it works at your University and not in your appartment.

Well something isn't working, that's what I'm trying to figure out, but I am sure I supplied the correct MAC address and that it was entered correctly. So I don't think the problem is related to the MAC address or that it is necessarily not working. There isn't a password on anything either. It should be a simple procedure, in that my laptop picks up the wireless networks fine, they are at full strength, and all that is needed is to click to connect to one of the networks and hey presto, internet...but for some reason it connects only to the wireless network and does not have internet access.

Waiting for your ipconfig output.
by Kees_B Forum moderator / September 11, 2011 10:25 PM PDT
In reply to: Kees_B

And, of course, it should help to have a look at router management interface to see what it says about being connected to your laptop (in stead of only seen from the side of the PC). But you need the tech guy for that,

I typed in ipconfig and this is the information that came up:

I also looked up some more information which might help. My wireless network connection is "Realtek RTL8191SE 802.11b/g/n WiFi Adapter." I looked through the contract of my flat and it says "The tenant is responsible for ensuring that their PC is compatible with a 802.11g wireless access point system." Could this be related to the problem I am having? Thanks

Re: ipconfig.

In reply to: Kees_B

The default gateway 172.16.0.1 might be OK. That should be the IP-address of the router. Of course, I can't check that. And it seems DHCP works, because 172.16.0.74 seems an IP-address that could very well be issued by the router.
For both addresses the 172.16 is somewhat strange, but not necessary wrong, I'd say.

But the "media disconnected" doesn't look good.

May I suggest that http://www.google.com/search?q=media+disconnected+wireless might point to a solution? If not, call that tech guy for help. He can look inside the router, you can't.

My laptop has TWO MAC addresses.
by R. Proffitt Forum moderator / September 12, 2011 5:31 AM PDT
In reply to: Bob

Did you give them BOTH?

And again, let them type in the WEP passcode.
