Thank you in advance for any advice and help. I have a wireless router connected to main computer in home. I use my laptop to connect to internet through the wireless router. Last night I noticed an error on the main computer stating "ip address conflict" because the two computers have the same IP address. I just did an IP look up and the two computers indeed have the same IP address. However there have been no problems in browsing the internet at the same time. Is there a real issue with the two computers having the same IP address?
