Well-explained, Leo. Instead of "additional" hardware, for simplicity I would suggest "replacement" hardware.
Apple truly solved this problem in a very simple way. Guest networking in any new Airport Extreme. Two SSIDs, two separate networks, one device. Brilliant. Done right.
Why not just use MAC address filtering on your wireless router. Just add the friend's MAC address to the list of allowed addresses. No WEP/WPA needed.
Craig - MAC address can easily be spoofed to connect. And without WPA, all traffic between the PCs and router can be openly read by a listener.
Rahul: Yes, but to spoof a MAC address someone first needs to find a valid MAC address to use.
And your traffic between PCs that are connected via ethernet cable isn't encrypted either.
And data on your ethernet cable isn't being broadcast to a 300 ft radius of your wireless connection. :-)
Leo: thanks for clarifying the pitfall of MAC address filtering.
And point taken about WiFI being broadcast, but the discussion was in the context of allowing friends onto your LAN.
Thanks for that info, Leo. May I ask what to look for to obtain a hub/switch.
I have a DSL Router. The original one died and the computer store people (Best Buy) suggested I replace it with another one from Verizon. It still uses WEP and can't, apparently, use WPA. As a DSL user are we stuck with old technology? What about FIOS fiber optic? If its router dies, can you buy a better one?
I have a wireless gateway with four ports at the back, so if a friend brings over a notebook or whatever I just hook it up with a length of network cable. Much easier and quicker than configuring the wireless connection.
In scenario 2, would it be possible to use a G- series router for the guests' usage without it affecting my encrypted N-series router? I remember reading previously that older router versions (ie G-series) can negatively affect the performance of newer ones. What effect can this have on wireless performance?
