Hi I have no idea about laptop/computers or internet connections or all this ip stuff or anything. Anyhow what it is for the past year I have been using a USB network adapter in my laptop to connect to the internet. I have a Belkin wireless router downstairs with my Computer and my Laptop up stairs. Anyhow I changed my RAM last week in my laptop and ever since my laptop wireless connection started going wrong. And yesterday it stoped working completely. I bought a new USB adapter today and I installed it and it says its got a good connection but the internet dose not work on it. When I click on view wireless connection it dose not fined my router or anything whats going on can anyone please help thanks.
