I just had the logic board of my MBP replaced due to a graphics problems. Following this repair, I am not able to connect to the MIT network using DHCP. This problem applies to both, wired and wireless connections. I tried setting a static IP manually, and this allows me to connect. Can anyone help with fixing the DHCP problem?<br>Thanks,<br>Miguel<br></div></blockquote></div><br></body></html>
