A series of noob networking questions

post #1 of 3
Thread Starter 
Maybe a network guru can help me out on some of this. I have a self build computer in my room attached CAT-5e to an OLD laptop that I have. They have a wireless/wired bridged network setup. Essentially, the desktop is sharing the laptop's Internet connection. Here are my questions:

1. Will these two computers share a MAC address? Will they share an IP Address?
2. The old laptop is running an 802.11g adapter. How much faster (numerically, not just 'a little faster') would a 802.11n card work?
3. I have a SeaGate USB 3.0 HDD attached to the desktop. From my new laptop (has 802.11n internet), I can save files through the network, through the old laptop, through the desktop to the hard drive. My transfer rate is 2.3-2.4 Megs a second. Is that normal?
4. Can I lock the external hard drive so that only I can use it? I do my backups there and would rather not have the other network users seeing it.
5. My desktop says that there is an IP address conflict on the network, but everyone's devices work fine.... (???)

Thanks in advance.

i can answer a few

MAC codes are unique to the hardware you have. Technically they can't be shared but they can be cloned by software
2. You will notice a significant boost in Local Network speeds, not WAN ( ISP speeds) Because 54 is the G rate, 300 is the N rate
3. if thats megabytes then that is 18 megabits per seconds which is correct
4. By default nothing is shared, but in Windows 7, you can right click share with nobody.

1) Depends. First half no, second half maybe. If you use bridging then each device will have it's own LAN IP. If you use Internet Connection Sharing, windows will implement NAT and you will both be behind the IP of the laptop.

2) Depends. How fast is your internet connection? Do you make a lot of LAN transfers? The difference for me from G to 2.4Ghz N was 1.5 -> 4.5 MB/sec. If you don't make LAN transfers and your WAN is under 12 mbps you won't notice a difference, aside from a bit of additional range.

3) You're still only utilizing G due to the old laptop and/or your router.

4) Why don't you just plug in the external to the PC you want to use it on instead of network sharing?

5) What IP and which devices?
