I have a technical question regarding home networking, a problem actually. I have a cable modem (Time Warner Cable), a Siemens wireless router and two computers (soon to be three) as a home network. My problem is this:My computer will drop access to the WAN (Time Warner) after 12 hours (to the second) of connect time. If I try ipconfig/release/renew (I mean correctly) I receive an error message that the DHCP server is unreachable. I have to turn off the router and cable modem for ~60 secs (but not the computer) then let them reboot to start another 12 hour...
