Separating Wireless and Wired Network

[I0s]

This is the current setup of my network.
The WRT54GL router has wireless turn on as I do need it for laptops. Is there a way to isolate wired and wireless network from each other but yet both networks can access the internet OR even better be able to access the internet and be able to transfer files between wireless computer with wired computer through an encrypted and secure connection.

I am not even sure if this is possible but my fingers are crossed.

Thanks

You can get another router to separate the networks. Put the laptops/wireless on the current WRT54G, connect 2nd router WAN port to WRT54G. Then put the dell switch, wired comps, printers on 2nd router. The problem would be transferring files and whatnot. You could use remote control software to do this though.

download dd-wrt
turn on vlans

put wireless on a different vlan from wired

I am so use to Thibor and love its stability and feature. Also, my whole network has already been setup. I really do not want to flash to another firmware =(

well, doesn't thibor offer vlan support as well?

The Tibur release is Great, it is very stable and it maintains the original Linksys interface.

However, it augments only basic functions (No fanct stuff like vlan), and it seems that Mr. Tibhor gave it up, the last upgrade was almost a year ago.

Another solution (more expensive) is this type of Network, http://www.ezlan.net/shield.html

In that case, I'd definitely flash to dd-wrt.

I've never had any stability issues that weren't self inflicted (read physically dropping the router ) and it'll give you pretty much all the functionality you'll ever need

The more I look into it DD-WRT sounds like a very good alternative, just that I am kinda lazy to setup the whole network again, assigning IP's and changing them etc...
btw, is the steps I need to take to get it up and running? http://www.geek-pages.com/articles/late...he_linksys_wrt54g/s/l_with_dd-wrt.html

um

why would you need to change any of the IP's on your network?
if they're statically assigned, and in the 192.168.1.x range like most linksys, then nothing changes

the router will still be 192.168.1.1

ps, that article is specifically referring to trunking, which is a different animal all together from VLANs (trunking is essentially combining the bandwidth of 2 ports)

 

[I0s]

Oh, I thought it was the same. This tells you how much I know about VLAN, hehehe.
So, all my wired network will be 192.168.1.1 and wireless 192.168.2.1 ?? Anyone connected to wireless network will not see 192.168.1.1 network?

I am sorry for all these question, just want to know more about it before I go set it up and reduce downtime.
Is there a guide online on how to do it?

btw, the article sounds like exactly what I need from their scenario "Network A is the standard internal LAN and Network B is an addition VLAN/Network that we setup." correct me if I am wrong.

Thanks for your help.

well
it depends on if you want wireless to be able to talk to wired, or not

 

[I0s]

I would like that, but will that compromise the security of the wired network?

without a real firewall/router between them, yeah

Is your main concern the loss in security on the wireless side? If thats your issue, just turn on WPA with AES. If you need security with the files, you could set up NTFS encryption, and have matching keys on both computers. This would prevent

1: Pretty mutch anyone except the NSA from getting into your wireless network.

and

2: Even if someone did get through the WPA encryption, getting through the NTFS encryption is damn near impossible.


P.S. I'm going to test and see if you can indeed use an identical key to use NTFS file encryption to share secure files.

You need to set up a domain (with a domain server) to use NTFS/EFS encryption over multiple computers.
