      Question Use of 'address reservation' to prevent losing connection?

      I seem to have developed a problem whereby my laptop (with wireless card) loses its connection to the network after about 10 minutes of use. I get a 'limited or no connection' balloon and then if I click for details it tells me the reason is that my router has 'not assigned an IP address'. Clearly, the router must have assigned one during the previous 10 minutes but then somehow it is coming unstuck!

      I am wondering whether using the 'address reservation' to reserve an IP manually for both my laptop and desktop machine (which is connected via a cable) is likely to solve the problem? I don't want to change anything in the router unless there is a solid basis for doing so (so far I've left everything alone).

      Any help appreciated.

      Have you turned uPNP off?

      I don't know anything about UPnP, so feel free to follow Koala5's advice before listening to me.

      First of all, does your desktop ever lose its IP address like this? Or is it just limited to the laptop? Are they both set to obtain IP address automatically?

      It seems very odd that the router would give out an IP address and then revoke it so quickly afterwards... as a workaround, you could manually assign IP addresses of your choosing to both your machines - that way, the router won't even have control over your IP addresses. This is a slightly more reliable solution than using the address reservation feature on the router, because with address reservation you are still relying on the router's DHCP server to function correctly, whereas by specifying the addresses on the client PCs themselves, you are taking the DHCP server out of the equation altogether.

      If you were going to go with this manual option, it would probably be sensible to either turn off DHCP on your router, or if you still wanted the possibility of adding other devices to the network later, just change the settings so that it assigns addresses from, say, 192.168.0.100 up to 192.168.0.253, and then manually assign your desktop and laptop 192.168.0.2 and 192.168.0.3 respectively. For example.

      If you want to pursue any of these ideas and don't know how to do them, I will give you instructions.
