After initially setting up the Win 7 laptop, in the case of the others I was asked for the security code and the connection was duly established. I am now trying to connect a friend's laptop, it is an ageing Toshiba Satellite M70-215 and from what I have been able to gather it is running Service Pack 2 and has only 512 MB RAM. I recently set up a wireless network for my new Sitecom WL-585 modem router with WPA-2 security and all went according to plan. I have a Win 7 laptop, Vista laptop, XP laptop, Nokia N95 and Soundbridge all connected.
I then tried installing the supplied Sitecom N adapter, after some problems the network appears but I can't connect, I am told "Windows was unable to find a certificate to log you onto the network" I read several threads that led me to uncheck "Enable IEEE 802.1x authentication for this network" and I actually managed to enter the WPA2 code but this just leads to the message "This connection has limited or no connectivity" and "validating identity". If you're familiar with wireless networks, the information in the "Summary" section is probably sufficient; if not, go to the Table of Contents below and find the section that matches your device's operating system.If you're having trouble connecting to a wifi network, you can sometimes fix the problem by removing and re-adding that profile.If the box was checked, then that was why you were getting the “unable to find a certificate to log you on to the network” message because Windows is looking for one, but your wireless router is not setup for certificate security. Once I unchecked that box and tried to reconnect to the wireless network, everything worked fine! Are you receiving an endless “Validating Identity” connection status when trying to connect to a wireless network.I tried to connect to the LAN using Ethernet (again after updating the driver), although I am apparently connected I can't reach the Internet and can't see what settings might need tweaking.
