I've read some of the other DHCP questions here, but my problem is a little different. I have a home laptop that has been working fine for ages. I brought my work laptop home at the weekend to finish a couple of tasks and connected it to my cable modem via ethernet cable - everything worked fine. Then I reconnected my home laptop, and it suddenly cannot find the dhcp server anymore. The IP address is (on both laptops) dynamically set, but even when I define a static IP address on my home laptop as being the dynamically assigned one on my work laptop (which worked OK), it still cannot get a connection.
ipconfig /release and
ipconfig /renew but it makes no difference. I suppose my network card on my home laptop could be defective, but would like to exhaust all other possibilities before I go down that route. Any ideas?
