Hello, I have two laptops, and each uses the wireless connection for every day purposes. I use IP network 192.168.2.0/24 for this. DHCP is used to assign these addresses. Whenever I need to move large amounts of data, I connect a cable to the home router, which can use 1Gb/s speed. I use the 192.168.67.0/24 network for this, and there is no internet access over this network. These addresses are assigned manually. However, both networks share the same LAN, through the switch/router. This setup up works very well. Recently, possibly as the result of an update, a strange behaviour is seen. When the cable is NOT connected, the wireless connection sometimes suddenly changes its "obtain DNS automatically" to "use the following DNS server address", and fills in a random ip address from the 192.168.67.0/24 network. As a result, most internet connections no longer can be found. Anyone any idea what could be causing this? TIA, Bart Zorn
