Hi hope someone can help me!
My housemate and I have both just purchased (within 2 weeks of each other) 2 compaq presario laptops with vista operating system and wireless enabled. We are with Virgin media for broadband. We also use a D-Link wireless router compatible with cable. For the first few days my housemate was able to pick up the router wirelessly no problem. Then our SSID didn't show up in her available wireless networks. I at that point was using an old laptop with XP OS with a wireless card but I was picking up the SSID signal OK. We were both in the same room with the router. Since I got my new laptop, it was fine for a week, the SSID was showing up but then one day my Available Wireless Networks doesn't show our SSID. It was however picking up neighbour's SSID so I presume my wireless receiver is working OK. If I run ethernet from the router to the laptop, sometimes it works, but sometimes it will just have a local connection and no connection from internet to router. I can however run an ethernet cable from the modem that Virgin Media provided me and access the internet that way!
