I have a desktop connected to the internet with a ADSL modem through USB port, a LAN connection to share the internet through a 5 port Switch, my internet speed is 512. Actually I don't use all the ports of the Switch, there are 2 of them that are not in use. My question is: Can I use the ports that are not in use to connect a Wifi access point to share wireless connection? If yes, what do I need to buy and how can I connect it?
Thanks a lot for spending your time reading this, and of course, your helping me.
That's exactly what an access point is for! Any model should do; Linksys, D-Link, Netgear, etc generally all make good products that will do the trick.
In most cases you simply plug them into the switch and configure the SSID (network name), channel, security options, etc via a web interface built into the access point. Configure your wireless clients to match and they instantly become part of your network.
Thank you for your explanation. Another thing that worries me is: Does wifi signals affect human health? Where should I place the access point ? (living room, bedroom?) If I want to put it inside the bedroom, will it affect health? I have searched on the NET about this, but I found nothing specific. Can you provide some information about this, please.
Need some advice on wifi connection
