Connected, but unable to access internet...?

[JulieMills]

Firstly, I'm not a techie... so bear with me!
My laptop is saying I'm connected to my wireless router, but I am unable to access the internet 
I've just returned from holiday and was using my laptop whilst away, but have since been unable to get back on my home network.
I'm using Windows 7.
Any help welcomed!

Quick test, unplugnyour router's power cable for about 20 seconds and connect to it again, see if your interner connection returns.
I sometimes get the same problem. Just gotta restart the router.

If it works, let us know.
If not, well, let us know too.

It worked briefly - on a linksys network (which isn't my default), but has disconnected again....

Duplicate post.

Do you have a cable you can use to connect to the router, instead of wireless, just to confirm the problem is exclusive to wi-fi ?

[JulieMills]

I'm using the same network to access my cable connected pc, so the problem definitely is a wi-fi one...

[grandpa_simpson]

I'm not sure what you mean by that..  Is the other computer able to connect to the Internet ?

[Carbon Dudeoxide]

Just to clarify, wired and wireless both have the problem?

On any computer, go to Command Prompt and type the follow

Code: [Select]

ipconfig /allAnd press Enter.

Post the Default Gateway. We may need this.

I have a desktop that is connected via cable and a laptop which is wi-fi - the desktop is working fine, but the laptop is connected but has no internet access.
I'll key in the config details from the lap top....

[Carbon Dudeoxide]

Oh so the desktop computer is always connected, whereas the wireless laptop periodically loses connection?

[grandpa_simpson]

Ok good..  We've confirmed that the router is indeed working and there is a working Internet connection.  

Now we need to make sure you got a connection to the dhcp server (in your case, the router) and that the router is rendering you an IP address. Next step is to do what Carbon said...   Click START, type "RUN" into the search box, when it shows up in the menu click on it.. type   CMD  into the RUN dialoge box and press enter..

type IPCONFIG at the prompt and press enter..

Does is show a default gateway address, IP address, and subnet mask ?

There's more info, but I'm manually keying it in... Hopefully the above will be helpful in the meantime...

If you were using it while you were away the network is set up to use the wireless connection that no longer exists. Go into Network Settings and choose your wireless connection as the default.

[Carbon Dudeoxide]

Yep, and make sure your network has top priority in the list.


Quick Q, have you tried the laptop via Internet cable to make sure it's not a laptop problem?

In addition to that, can you tell us the model number of your router.

[JulieMills]

My network is showing as my default (and is top of the list) - saying connected, but no internet...?
I haven't tried using a cable to connect, but will...
I'm not sure how I get my router model number.... It's a BTHomeHub.2.0 if that helps?
