and welcome to the WTT forums, sorry to hear of the Wi Fi problem with your laptop..... but at least its good news that Ken has had a look at the internal running of your machine and can't see any malware showing.
As I understand it, from taking a quick look at your logs, another machine on your network can operate wirelessly and connect to the Internet satisfactorily..... is that right?
if so it indicates that your modem and router are working Ok and that the fault lies within the unco-operative laptop computer.... so that's where we need to concentrate our efforts.
To assist in troubleshooting I would like you please to:
1 check and double check that your wireless is switched on...on your computer, depending on make and model there may be a hardware switch or software key stroke using a function key...often a LED will illuminate to confirm that the wif fi is switched on.
2 Check in Device Manager that the wireless network adapter is working.... here's how
3 Click on Start
4 Right click My computer
5 Click on Properties
6 Click on Hardware/Device Manager
7 Scroll down to Network adapters
click the + sign next to network adapters and locate the network adapter that has Wireless in its title.
8 Please advise us the exact name of the wireless adapter in your next reply
9 Look carefully at the entry for the wireless network adapter.... is there a yellow marker or a Red marker against its name...(please advise in your reply)
10 right click on it.....is it said to be working OK? please advise and also list any error messages that you see in your next reply.
11 Check to see that no proxy servers have been "slipped into your computer" by subtefuge here's how:
12•Go to Start > Control Panel, and choose Network Connections.
•Right click on your default connection, usually Wireless Connection, and choose Properties.
•Click the Networking tab
•Double-click on the Internet Protocol (TCP/IP) item.
•Write down the settings in case you should need to change them back.
•Select the radio button that says "Obtain DNS servers automatically".
•Click OK twice to get out of the properties screen and restart your computer.
•If not prompted to reboot go ahead and reboot manually.
13 In Internet Explorer.
•Check Internet Options settings.
•Tools > Internet Options > Connections
•Choose "automatically detect settings"
•uncheck/untick/clear both proxy settings boxes
14 InMozilla FireFox (if you have this installed)
•Click on Advanced -> Network -> Setttings…
•the No Proxy option should be selected.
15 Next reboot your computer once again and now go here: (use an Internet enabled computer and download and use a CD to transfer to the uncooperative computer) the WinSock fix
Run the WinSockfix tool.
16 Reboot your computer once again and see how it goes with the Internet, if still no joy then do this:
17Click on Start
Click on run
type in the white box
press Enter key
at the DOS prompt type in:
cmd /c "ipconfig /all > postme.txt & ping bbc.co.uk >> postme.txt & notepad postme.txt & del postme.txt"
Note please use "copy and paste" (Ctrl+c and Ctrl+v) for these commands, as this will automatically make sure you get the spaces correct! and also don't forget the opening and closing inverted commas, they need to be there...
Please copy and paste the output into your reply (Make sure you capture it all) and let us know the following:
The make and model number of your laptop
