Symptom:
getting hard time to connect network. when I connect cable to the internet my network card light up and connecting to the internet. But when i connect SD connect it says network cable unplugged. and no lights from back of laptop from network card. And when i connect C4 to other laptop network is working and connecting fine. I don’t know what else to check.
Solution:
Read Diesel Benz info above. Then to set your IP in Windows XP network connections first, in order to connect to your SD by wire. The same applies to wireless connection. SDconnect is using Static IP addresses; hence, you need to change that.
