Xeo, I kinda wanted to do something similar between 2 houses. Thing is, I wasn't sure 802.11b works real well when the signal goes through walls and the outside. If you get it to work, let me know.

i got it working, i just cant access the router from BOX 2 and BOX 3 but the rest of the boxes can access the router fine.

Boxes 2 and 3 can still be browse the internet, they just cant administer the router. How can i make it so BOXES 2 and 3 administer the router?

Hey XeoNoX. I have a Linksys router/switch also. I haven't tried it ... but I suspect the Linksys router/switch isn't letting your Boxes 2 and 3 access it because they are on different networks and this is probably a security feature of the Linksys router. There might be a way to turn this off, or there might not. I haven't looked at it, but I would suggest checking the documentation.

About sending DHCP to boxes 2 and 3 - you could do it two ways. It looks to me that you're routing them right now. Routers seperate networks and create what are called "segmented broadcast domains". DHCP is designed to use broadcasting in order to find a DHCP server and for the server to give an address back to the requestor, when it doesn't actually have an IP address yet. However, when you introduce a router, you chop off the broadcasts. This is typically worked around in a "professional" network by using DHCP forwarding or what Cisco would call "IP Helper". I don't know if your OS, or whatever you're doing to route, has this feature.

The 2nd way is to bridge. Again, this would depend on your OS. If you can bridge, then it appears to be one segment and broadcasts would reach your whole network, including DHCP. Also, I think this would solve your Linksys management problem.

HTH!

thats exactly what im trying to do right now, is bridge. Im trying to bridge.

I have it kinda bridged right now, but i have those problems i explained. I dont think i have something configured right.

Can you explain to me how to bridge the network that i have in that diagram?

Im pretty sure i dont have an IP address somewhere where it should be, but i dont know which box should have what. I have it setup as best as i can right now, but somethings not right. can you tell me what IP's to bridge with the correct subnetmask, ip, and gateways? Im running Windows XP wich is capable of bridging.

Btw, Boulware5, for future reference, 802.11b doesnt really go thru walls that well, i am using the Linksys befw11s4 v2 with the AIR Plus D-link DWL 520+.

The router is a room that is located at the corner of the house by a WINDOW. Note: A near by window is the key. Move it a couple feet from the window and it loses signal. The two computer are between 180 ft to about 220 ft apart from each other and i still had to use an OUTSIDE coffee can (which is currently rusting) attached to the dlink wireless card to catch the signal, this network is so rigged its not even funny.

All this work just to split and share a cable modem connection with my friend, of course i am on the receiver end cuz its his cable, lol. We split the bill. Im up about 95% of the times and i only need to adjust the can about 3 times a week. (takes 5 mins to adjust the can, thats 15 mins a week at 1hr a month, at half a day in a year, at a full day every 2 years........WOW!!! I guess i must not have anything better to do other than mess with computers)

I hope that what you wanted to know Boulware5.

LOL. I've never heard of Boulware. Of course, I don't know everything!

LMAO @ the coffeecan antenna.

You need to bridge on the machine with the wireless card and the wired card. You need to bridge the traffic together. If you can do it, then you will have 1 network - the IP addresses would all be the same - I mean the same subnet mask and probably consecutive address numbers.

A bridge is 1 network. A router is 2 or more networks.

You could just buy a Wireless bridge - designed for exactly what you're trying to do - connect seperate points of the SAME network. The Wap bridge would have an antenna and a ethernet interface to connect to the 2nd side of your net.

What OS are you running on the machine with the Wireless and wired nics?

lol

Boulware is the moderator of the forums, i was just letting him know some stuff about how *cough* great *cough* 802.11b works.

Anyways, back to my dilema.

I know if i get the wireless bridge it would do what i want my network to do, but im not trying to spend more money :-)

Im pretty sure there is a way to turn box 1 to do the job of the wireless bridge and thats what im tryng to accomplish.
