Connected to wireless but no internest connection

[RachieA]

Hi, I am a bit clueless when it comes to computers! I have a desktop which connects fine and the internet works fine. I bought an Acer Aspire laptop a couple of months ago and that worked fine initially but a couple of weeks ago it stopped connecting to the internet even though it said it was connected to my Sky wireless broadband and that the signal is strong. I have windows 7. The driver is atheros ar5b97.

 

When I ping 127.0.0.1 this works.

 

When I ping 192.168.0.1 it says "destination host unreachable".

Ping statistics "Packets: Sent = 4, Received = 3, Lost = 1 (25% loss) ".

 

I'm desperate to get online and would be grateful for any help.

Hi and welcome.

 

Try resetting the router.

Switch off > leave for 1 minute > switch on again.

 

 

Also try right click on monitor icon ( bottom right of screen ) and select "Repair"

 

Can you access the net with this laptop if you use an ethernet cable direct to the router?

[RachieA]

Thanks for replying. The first didn't work. The second - I don't seem to have a monitor icon????

[GRANDAD]

Hi, this may appear a bit daft but, as I have an ACER ASPIRE laptop also, I too had this fault-so I thought in the early days===at the top of the key board there is a symbol that looks like a satellite dish which should be flashing. If you press the button it will say WIRELESS LAN DISABLED, press again and it says WIRELESS LAN ENABLED AND THE SYMBLE FLASHES, hence connection.

 

I had inadvertently disconnected somehow and it took alittle while to find a simple solution.

 

Hope this helps!!

Hi GRANDAD,

 

This is certainly worth looking at.

I don't think that RachieA would be able to send any packets with the ping 192.168.0.1 if the wireless was switched off.

But - let's wait for RachieA's reply before we try anything else - this may explain why there is no icon :)

[RachieA]

Thanks Grandad, unfortunately it was not this simple! It is enabled.

Click the > next to Network Adapters.

 

Do you have anything with Wifi / Wireless listed ?

Any yellow exclamation marks or red Xs ?

[RachieA]

It says:

 

"Atheros AR5B97 Wireless Network Adapter"

"Broadcam Netlink Gigabit Ethernet"

 

There are no exclamation marks or red crosses.

[KenB]

Is 192.168.0.1 the usual path to get you into your router software?

Can you access the router software?

 

Are there any other wireless machines that ARE able to connect ?

 

Try repairing the connection.

Can you access the router software? I don't know what this means.

 

Are there any other wireless machines that ARE able to connect ? Yes my child's tutor has an Acer that can connect.

 

Try repairing the connection.

See here:

http://www.dummies.com/how-to/content/how-to-repair-a-network-connection-in-windows-7.html The troubleshooter couldn't find the problem

 

See red comments above.

Can you access the router software?

Open your browser ( click on the icon )

In the address bar at the top ( where http:// etc is ) type in 192.168.0.1

Does this give you access to your router? ( you may need the login name and password )

 

=====================

 

Start > type in ......cmd.....at the top of the page right click cmd and "Run as Administrator"

At the prompt type in .......ping http://www.google.co.uk

You should get 4 packets sent and received.

What results do you get?

 

====================

 

At the same prompt type ......ipconfig /release ( note gap after ipconfig )

then type .....ipconfig /renew

Hi, to add to Ken,

sometimes with some routers just the IP numbers may not go anywhere. I have an Edimax router and to get into that it needs the full address of http://192.168.2.1

Once the page opens and providing no other log in or password has been set, the usual manufacturers log in is "admin" with the password "1234"

That should then allow you to get fully into the router software and carry out any adjustments or changes.

Does this give you access to your router? ( you may need the login name and password ) It just says it cannot display the page.

 

=====================

 

Start > type in ......cmd.....at the top of the page right click cmd and "Run as Administrator"

At the prompt type in .......ping www.google.co.uk

You should get 4 packets sent and received.

What results do you get? "Ping request could not find host www.google.co.uk. Please check the name and try again."

 

====================

 

At the same prompt type ......ipconfig /release ( note gap after ipconfig )

then type .....ipconfig /renew They all state "media disconnected".

This confirms that your laptop cannot communicate with your router.

 

If you right click on Atheros AR5B97 in Device Manager > Properties

Does it confirm that the device is working properly?

 

Start > type in .......services ......ENTER ( hope this is the same for Win7 )

Scroll down to

Wired Autoconfig - should be Manual or Auto

WLAN Autoconfig - should be Auto

 

Are they?

 

=======================

 

Use cmd again - Run as Adminitrator

Type in ipconfig /all .......note the space

You should get a long list.

In the top corner will be a small black icon > right click > Edit > Select all > copy

Use CTRL + V to paste the list here.

Just looking at the AR5B97 adapter properties - advanced - network address says "not present" I typed in "192.168.0.1" thinking I was being clever but it still didn't work so I've changed it back! Is it correct to say "not present"?

[RachieA]

Looking around I tried this:

 

netsh winsock reset catalog (resets winsock entries)

netsh int ip reset reset.log hit (resets TCP/IP stack)

 

I got internet connection for about 10 seconds, then it went again! Any ideas?

[KenB]

AR5B97 adapter properties - advanced - network address says "not present"

This is not correct.

 

Start > type in ....services......ENTER

Scroll down to Workstation.

 

This should be set to "Automatic".

Is it?

 

=====================

 

I don't see how I can do this when I can't connect to the internet

I switched my wireless adapter off and was still able to run ipconfig /all.

However, if you have no network at all - then it is unlikely to run.

Give it a try.

If you have a flash drive ( memory stick) then paste the results into Notebook > Save it and paste it here.

 

I am beginning to suspect that your Network Adapter has died.

 

Suggest you get a USB network adapter and give this a try.

(example only)

They are not expensive.

[RachieA]

Finally I have managed to copy the results of ipconfig /all!

Hi,

 

Hope this is the same in Win7 .....

 

Start > Control Panel > network & sharing > Manage Network Connections ( left pane ) > Right Click on "Access to Local Internet" > Properties

Uncheck IPv6(TCP/IP) > OK

go back ....

Highlight IPv4(TCP/IP) > Properties

Make sure "Obtain IP Address Automatically" and "Obtain DNS Server Automatically" is checked.

[RachieA]

I have done this and there is still no internet connection.

[KenB]

Where they checked anyway - or did you have to check them?

 

The "DNS Suffix Search List" is not showing in your IPconfig results.

 

Go back to "Obtain IP Address Automatically" and click on Advanced > DNS tab

Under DNS Suffix for this connection:

Is "register this connections addresses in DNS" checked ?

[RachieA]

Where they checked anyway - or did you have to check them? 'Make sure "Obtain IP Address Automatically" and "Obtain DNS Server Automatically" is checked' - these were ticked already.

[RachieA]

My previous reply is regarding the atheros adapter which it says is connected. There is also "wireless network connection 2 - not connected - microsoft virtual wifi miniport adapter". I haven't unchecked ipv6 on this one and not sure why I have 2 wireless adapters?
