Need Advice About Spliting a Home Network - Part WEP, Part WPA
Posted on 2007-11-29
First, let me say that I am not very experienced with networking so please forgive me if I misuse terms. I set my home network up a couple years ago, without much trouble, and have modified it a few times since then, but that's about all the experience I have.
Currently my home network setup consists of Cox 7 Mbps cable, Motorola SB5101 SURFboard modem, Linksys WRT54G wireless router, one CAT5-connected desktop running WinXP SP2, one CAT5-connected printer, two wireless laptops running WinXP SP2, and one TiVo Series 2 connected wirelessly using a Linksys WUSB11 adaptor. Currently I am using WEP for the wireless connections because that's all the TiVo supports. I have ZoneAlarm Pro on the desktop, and Norton Internet Security on the desktop and laptops.
What I've wanted to do for quite a while is "split" the network into a WEP side for the TiVo and a WPA side for the laptops. Recently I was given a Linksys WAP54G access point and a BEFSR41 router so I think I might now have the necessary hardware, but not enough knowledge about how to set things up.
1. I know that using WPA on the laptops will help prevent eavesdroppers from decrypting transmissions to and from the laptops. Will it do anything else for me?
2. Can WPA in any way prevent someone from "getting into" my laptops or desktop?
3. Is subnets the way to go, or is there another way?
4. I currently use TiVo Desktop software on my desktop and one laptop. If I split the network will I lose the ability for TiVo to communicate with the Desktop software? (I use ZoneAlarm Pro on my desktop and it was hard enough to get TiVo Desktop to talk to the TiVo through ZoneAlarm.)
5. Anything else I haven't thought of?
Please let me know if there's any other information needed to provide an answer.
Thank you for your help!
