Environment

  • Laptop A (Windows Vista)
  • Laptop B (Windows 7)
  • Phone A (iOS)
  • Phone B (Android)
  • Phone C (Android)
  • Wireless 802.11 g/n 2.4GHz router (Billion 7800NL)

Problem

When Phone C enters the house and connects to the wireless LAN, Laptop B disconnects from the wireless network; Windows shows that it isn't connected to a wireless network at all. When this happens, all of the other devices stay connected and work normally.

Once when the laptop was connected while Phone C was already in the house, the problem happened again after a while of normal use.

Troubleshooting

  • Tried reconnecting to the network. Windows said it couldn't. Another time it did connect, but it said it had limited connectivity.
  • Tried restarting the laptop. This didn't help.
  • Tried restarting the router. This fixed the problem temporarily.
  • Ensured that the router was acting as a DHCP server and had enough IP addresses available.
  • Ensured that none of the laptops or phones were assigning themselves static IP addresses.
  • Tried moving the laptop close to the router. This didn't help.
  • Checked that the IPv4 addresses were unique.

Any ideas about what could be causing this? It sounds like it could be a problem with the laptop or the router.

Sounds like a they might be getting conflicting IP addresses or a bug in the routers software. You can try making sure they are getting different ip addresses or check to see if there are any updates available for your router.

I found that there was an update for the wireless card driver available through Windows Update. After installing it, the problem no longer occurred, so I suspect it was a driver problem.
