Problem

I have a very strong wireless signal, but I am unable to connect to the internet while at a resort in Cancun Mexico.

 

Strong wireless signal but no internet

Explanation

Currently, internet connections use the TCP/IP protocol, (Transmition Control Protocol / Internet Protocol). Indeed, your browser and your email programs both use TCP/IP to connect to the internet.

This protocol should really be named TCP/IPv4, and offers about 4 billion addresses. Unfortunately, the world is fast running out of addresses, hence the introduction of the TCP/IPv6 protocol.

Very briefly, TCP/IPv4 is based on a 32 bit address, while TCP/IPv6 is based on a 128 bit address. This will allow a staggering amount of addresses (3.4 with 38 zero's).

As it is introduced, TCP/IPv6 is initially used in a dual stack mode IPv4/IPv6. This will usualy not create a problem, however, under some Hotel IPv4 setups where an authentication of your computer is required, your Windows XP or Windows Vista computer will not be able to connect to the internet.

 

Solution

Uninstall TCP/IPv6, and use TCP/IP or TCP/IPv4 by itself.

Uninstalling TCP/IPv6

 

(Left Click) scgsb Control Panel and select Network Connections:

 

Network connections icon in control panel

 

scdon any internet connection and select Properties

 

Opening wireless properties window

 

TCP/IPv6 uninstall

 

scgon TCP/IPv6 and select Uninstall.

Re-installing TCP/IPv6

As with the uninstall process, you will have to open up the Network Connection Properties window. The example above was with the wireless connection, but any connection can be selected, since this protocol is used for all internet connections. To illustrate this, we are re-installing TCP/IPv6 via the Local Area Connection Properties window.

Select Install

 

install new Internet Protocol window

 

This window will open, and you may have to slide the cursor down until you see Protocol. Select Protocol and press on Add...

 

select new network protocol

 

TCP/IP version 6 instalation

 

 

Select Microsoft TCP/IPversion6 and press OK.
