I had an older Siemens Speedstream 2624 Wireless Router that I no longer need and gave it to a friend. He plugged it into the electric outlet and then connected it from its WAN port to his ComCast cable modem. He then connected his desktop computer to to one of the three available ports on the wireless router. He fired up his wireless- equipped Thinkpad and found and connected to the Speedstream. But when he sought to surf to web sites he invariable got the "Server Not Found" message. He gets the same message when he tries to surf using his desktop.
Could it be that he is unable to surf anywhere because he did not configure the router using the configuration CD that came with the router (it cannot be found). But the router worked fine at my house. Does the router care which cable system modem it's connected to?
What can he do to make this wireless router work for him? Has he failed to do something that needs to be done?
