Cannot connect to internet

You will need a wireless router, like the Apple Airport Express. It will connect to your broadband modem via an RJ45 (ethernet) cable.

Sounds like you need to change the TP link router for a wireless Access Point or a range extender.
Who knows what goofing around BT does with their equipment.

It doesn't need a separate modem; it replaces a modem in your home network. If it's properly connected to the phone line, and you have an internet service provider (ISP) supplying you with a broadband connection, and the PC is connected to the router, then it should all work fine.

If it isn't all working fine, the most likely problem is either that the wires aren't connected in the right places, or that the PC's internet connection isn't set up properly (e.g. if you changed from dial-up with a modem to broadband with a router).

If you have recently changed from dialup to Broadband, and you're running Windows, use the Network Connections wizard to set up the internet connection. In Windows XP you can do it this way:
1) click on Start
2) move the mouse to Settings
3) click on Control Panel
4) double click on Network Connections
5) click on File
6) click on New Connection Wizard
7) follow the instructions.

Your ISP should have sent you a CD-ROM to help you to connect, so insert the CD when prompted by the New Connection Wizard.

Sometimes you can just insert the CD into the computer and you'll be prompted to do everything necessary to connect to the internet. BT, for example, do it this way.

Good luck!

connect the broadband modem to the internet port of your router (probably is blue). Then connect your pc to the router.

You have to set your router to act as dns.

You will need to check the wireless settings of the router .
Is there any computer connected to the router with the Ethernet cable?
If not then connect 1 computer to the router and open the router set up page. Once you open the router set up page, you will be able to find the wireless network key.
Use that password to connect to the wireless network

your user name and password have been entered incorrectly, they are case sensitive and must be exact. Make sure your ADSL settings are set at 0/38 (you'll see where)

Assuming your connecting wirelessly, test it by directly connecting to it with an ethernet cable and then run a speed test. If it dramatically improves, you have a wireless problem ( router, wifi card, poor reception, etc.) If it stays about the same, probably poor speed from your broadband provider.

Your sister was accessing the wireless access point at school which is connected to the Internet/WEB access via a router and the school's broadband service provider.
For you to access the Internet using your wireless adapter on your laptop, you need your own wireless access point and connect it to a broadband ADSL or cable modem and then connect it to an Internet Service Provider. Some Internet Service Providers (cable and ADSL) can supply a combined modem/router/wireless Access point.
If you already have a broadband modem all you need is a wireless access point/router. You only need to configure the wireless access point and your wireless adapter so they will communicate with each other. Folow the instructions in the manuals.

Try to reset the router for 20 seconds. There's a reset button at the back of the router. Just press and hold it down for 20 seconds, then unplug the power for 30 seconds, the plug it back in. Now try to reconnect to the Linksys wireless network.
