I prefer to keep my wireless network SSID as is and change my wired LAN name. Is there anyway to do this? Thanks.
I found how to change the network name:
Network Name and Icon - Change. So now my desktop running Windows 7 on a wired LAN and my laptop running Windows 7 Starter on a wireless LAN have the same network name.
However, still no luck joining the homegroup from my laptop.
I am going to look into the firewall next. I'll keep you updated.
