After installing widows 7 my ip behind my router changes to 172.xxx. it use to be 192.xxx not showing on my router list. funny thing is i can get on the internet. anyone know what is going on?

Is that what your ipconfig says? Or is this what you use to logon to your router?

this is what my ipconfig says. 172.xxxx but all my router leases are in the 192.xxx range. i can get on the internet but i do not know where or how i am connecting. not showiing a 172.xxx in router

perhaps you are connecting to a neighbors router? this often happens when you donot change the default SSID name and when you don't secure your router. orsomeone reset your router. connect to your router with a wired connection, reset it if needed, establish anew unique SSID name and set up WPA2-AES wireless security. Then connectwirelessly to the new SSID name.Barb Bowman www.digitalmediaphile.com

Hi, Please also check your network settings: 1. Go to “Network and sharing Center – Change adapter settings”. 2. Right-click the connection that you want to configure, and then click Properties. 3. Click Internet Protocol version 4 (TCP/IPv4), click Properties, and check if the settings are proper. 4. You can configure the NIC settings to obtain the IP address and DNS automatically to see if it works. Hope this helps. Thanks. Nicholas Li - MSFT
