- 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)
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.
- 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.
