The extender works fine and connected no issue.

However, once the extender is connected, any new connection to the pre-exisitng wifi networks will not have any internet. This includes PCs who were connected prior to the extender being turned on.

Further, resetting the extender allows the PCs to regain internet connection temporaily until either they are reset or the connection is changed.

LAN connections to the modem are unchanged.

I do not see how an extender being connectioned would cause internet access to drop from every other wifi network.

Thank you for any help/suggestions you can provide.
