I have two Win 7 Dell XPS laptops that lose internet connectivity on a regular basis. I've researched it through Dell, upgraded wireless drivers, etc. Still no permanent solution. When connections are lost, I've found that when inspecting the DHCP connections, that both IP leases are expired, even after I've manually had to "renew" them days ago (lease is suppose to be 43195 minutes). Not sure why they are expiring early or don't auto renew. By renewing them, I mean I attempt to delete the leased IP through the "remove" action on the DHCP admin screen with no change in the status screen, i.e. the action doesn't appear to work. I finally have to reboot the router. I've had to do this twice this morning. Sometimes we can go weeks without issue, then suddenly it happens multiple times. I have zero issues with Apple products like ipad, iphone and mac pro. So it leads me to believe it is either Dell, Windows, or the router (Actiontec MI 424) in some combination.
Any help would be appreciated.
A few possible Fixes.
Stop DHCP Assignments from the Router, by statically assigning them via the router interface.
Follow these instructions for that.
If all else fails, then I Will offer this bit of advice.
This problem actually has happened before and to a number of my clients. For one in particular, and many moons ago, the only thing that seemed to fix it was to Disable APIPA.
In /95/98/ME/XP/2000 environment, I can tell you how to do that, but have not done so in a win 7/vista environment.
Thanks for the quick response and suggestions. A while back I tried static addresses, but the problem still existed.
I found this
I've changed channels after finding another network on channel 11. Not sure that's the conflict, but will give it a shot.
I thought about just replacing the wireless adapters after reading about particular problems with Intel's WiFi Link 1000 BGN or less ideally, just run a cable direct.
