see how ueless I am at computers, yes it's a dongle.
I've never tried it without the dongle, I used to have a Lynksys wired and belkin wireless router.
When this problem started I was told by "The Tech Guys" to dispose of it and buy a netgear wireless router and wireless dongle.
It's not resolved the problem, I've been through to the tech guys many times, and although they access my desktop remotely and repair it, as soon as they've disconnected the session, the problem starts again.
Will need to use the wireless dongle if it is an oldish computer with no wireless connection.Is Router and Computer in different rooms and who is your ISP is it Virgin.Maybe drivers needing updated but I know not a lot about Routers.
Looking at your image in your original posting have you made sure that your Wireless Zero Configuration is running? Go to Start/Run/type in services.msc and click OK. Scroll down to the Wireless Zero Configuration entry and check that it is running. It should say "Started" and then "Automatic". If not then right-click on it and select Properties - under Service Status click Start and also make Start Up Type Automatic. Click Apply and OK.
