Losing IP address when trying to reset a router

January 25, 2012 at 18:22:23
Specs: Windows 7
I own a HP laptop (runs Windows 7), and lately when I either turn it on or log back in for the first time in a day, it's not connected to the internet, despite my brother's desktop computer (Windows XP) being connected (it's right beside the router and modem). Before, we would have to just unplug the router for a few seconds and then plug it back in again to get the connection to work again on my laptop, which that alone we don't understand why, as there are periods of time we have no problems connecting on either end, like I just bought this laptop at Christmas and have had no connectivity problems until now. Now however, when we unplug the router and plug it back in, it kicks my brother's computer off the internet despite his connection being good prior to, apparently it loses its IP address when we do that. So then we have to unplug/replug the modem and router plus sometimes restarting my brother's computer to finally get it working again. This makes no sense to us. Why is this happening?

try setting a static ip address (higher than the default and in same subnet) in and use the router address as the dns. Just to see if it works that way.

re: wanderer or anybody

It definitely appears to be the router. To clarify what is exactly happening; when the problem occurs, my brother's computer which is the wired computer on the network that the router runs off of, has connectivity to the net and to the router. It is at this point that my laptop and other wireless devices cannot connect, which happens on at least a daily basis. In the past we would fix it by resetting the router by unplugging it, and that would usually work. What happens now is the router resets but then stops functioning after a minute or so, my brother's computer does not connect and the wireless devices do not even have the option of our home network in their respective menus. The router itself has different lights on it where it is quite easy to tell when it's not functioning, the modem does not even have to be hooked up for that to be clear. After several tries the router will usually hold its signal and will be fine for the rest of the day.
Do you think updating the firmware will make any difference? The only other question would be, could there be something on my brother's computer that could be causing the router to fail so quickly after it resets?
