Our home network has been acting up for about a week. It not longer seems to be able to hand out IPs in an orderly, timely and steady fashion. It seems to be affecting ALL connected devices, BOTH wired and wireless. We don't all get disconnected at the same time. It's all random when it happens for anyone.
Our setup is modem --> router --> switch. We have tied unplugging them all for several minutes but no improvement.
The problem just started all of a sudden, no one has changed any internet setting on anything that they are aware. We have checked individual machines to make sure nothing was switched to a static IP, for some reason. But unless we missed one they are ALL dynamic.
This is what it's like for my computer (but it's pretty much the same for all of them) that's connected via an ethernet cable. When I start up from being off it will spend a couple of minutes connecting and disconnecting from the network. Then it will stay mostly on, but randomly getting kicked off now and then for a minute or so. The internet connection icon on my task bar will say "unidentified network" when it's not working.
I tried doing ipconfig /release
and ipconfig /renew
from the command prompt and it actually said the IP was already in use. So what can we do to figure out what is causing it and hopefully fix it? Is there some way we can check and see what is hooked up to the network, if there is some static IP mucking things up? Or if there is some DHCP server conflict? Could it be our ISP causing it and it's not an internal network problem, at all? We have not yet called our ISP since we own our own modem, so we don't expect them to be helpful.
Googling for answers has mostly given results on how to figure out why one individual computer can not connect to wifi which is SO NOT OUR PROBLEM!
