Hi friend,
Just to share.
"Wireless is way to go" is a yes and no situation. This is because wireless networking will have security problems especially you are in HDB or houses so close to each other. I have experience where people can actually accessing my internet. Luckily, I did not share any files or folder for my system and now I block all IP address except those I designated
If you have a new house, the best is to have wired point at every room, living room and kitchen and best is every room has a SCV point. It would be helpful if you decide to shift your modem here and there.
Anyway, you can get a router, you can buy one with wireless and with 4 ports. the cost is rather cheap now compare to 4 years ago!
I attached 2 photos for your information since you are using old modem from starhub. Please note that you need a modem which provide a cat 5 cable out so that you can connect to your router.
Regards-fooyl
