Should I have the cable coming IN from the router plugged into the Uplink or just a regular port on the switch? I've been trying it with both, but if I knew which one to use it'd make things a whole lot easier and quicker.

No go. Still didn't work.

Cable should go into the Wan port which is probably separate.

On the switch I dont have that. I only have Port 1 2 3 4 5 and Uplink

Can we check the stae of play? Leave the switch out of it for the moment, although the computers are connected into 1-5. It only has 5 ports so if the uplink port is connected port 5 is disconnected.

Do we have:
Modem connected to Wan port on router.
1 computer wired to router.
Router set to 192.168.1.1
Subnet 255.255.255.0
In the Run box type cmd /k ipconfig to check what the address has been given to your machine. What does this say?

From a computer wired to the rotuer

Those computers plugged directly into the router run just fine. Once it goes through the switch is where the problem crops up.

Right this looks OK. Plug a patch lead into the router and connect it to the switch any port 1-5. Connect another computer to the switch. Check to make sure it is set to obtain an address automatically. On this computer check its address with cmd /k ipconfig /all.

I'm sorry, but what do you mean?

Connect the router to the switch with an ethernet cable.

Hello.

I use a very similar setup at work and home. Piece of cake to set up.

First, reset your router by holding the reset switch. If you use DSL for highspeed (think you said you did), make sure you have the logon for it (if your DSL requires it).

Next, set everything up like the diagram I attached.

The Linksys router will have the DHCP server enabled by default. This will give out IPs in the range of 192.168.1.100 -> 192.168.1.150. This is fine, you can leave these on. Don't worry about trying to be more secure by using other IPs, you'll just have more problems.

The Linksys router will have an IP address of 192.168.1.1 . This is ok. The default password will be admin. You will want to change this as soon as you log in.

If you hook everything up like in the diagram and have your computers set to automatically obtain an IP, then they should be talking. You should give them both a reboot though just to make sure they grab a new IP.

The first computer to obtain an IP address will be given 192.168.1.100. The second will be 192.168.1.101. Go to a computer and go Start->Run->cmd . At the command prompt, type " ipconfig ". If the ip ends in 100, try to ping 192.168.1.101. If the ip ends in 101 , try to ping 192.168.1.100.

The reason I put the XBox at 192.168.1.151 is because that is outside the IP pool of the LinkSys DHCP server. I have a playstation and give it that address because I then enable the DMZ in the router and point it at that. Makes life easier.

Anyways, this is just the basics... I'm tired and its late.. Tommorrow I will get into securing your wireless and setting up port forwarding and such so that you can use things like BitTorrent at full tilt.

Cheers,

See, the problem is that there is no uplink port on the router

You don't need an uplink port.

Ok, I looked up the user guides for the BEFW11S4 on the Linksys site and they showed an uplink port.... wouldn't be the first time Linksys lied to me though.

The switch has an uplink port so your still ok. Plug your long cable into port 4 of the router and then plug the other side into the uplink port of the switch. Make sure that nothing is plugged into port 5 of the switch though. All the uplink port does is provide a crossover on the port.

After you hook the cables up, reboot both computers 1 and 2. Well, you could just do an ipconfig/release , then ipconfig/renew .

After rebooting or doing the above, do an ipconfig/all . If both computers pick up an ip address then your going to be ok. If they don't... make sure that you haven't accidentally used a cross-over cable to connect computer 2 to the switch. Let me know if you need to know how to tell if crossover.

I have the pretty much exact same setup at work. Different router (still Linksys) and same switch... works easy.

Ok, I did what you said. Reset router, IP is now 192.168.1.1, DHCP enabled. Computer 1 got an IP just fine, 192.168.1.100. I took the long wire, plugged it in the back of the router, and then ran it into the switch's uplink port. Plugged a cable into the back of computer 2, and port 2 on the switch. Computer 2 could not get an IP. I did ipconfig /release and then ipconfig /renew and it said

C:\Documents and Settings\Brian>ipconfig /release

P.S. I don't think I mentioned that the wire coming from the router goes into a walljack, and then I have a long cable coming from the walljack into the switch w/ Cat 5 ends crimped on the end. Does that make a difference?

It could do - do you know if the lead is good. Take the lead out of the uplink port and put it in another.

Well when I plug it in the switch, the lights come on, but the activity is constantly blinking, fast. Right now, I'm using computer 2, with the wire that comes in plugged directly into computer 2, so it does work.

This goes straight back to the router and you now have two computers getting addresses from the router. This only leaves 2 possibilities either the cable that you connect from the switch to the computer or the switch itself are faulty. Do you have another lead to substitute?

The only combinations you can have are the computer in a port (this is definite) and the lead from the router in either an nother port or the uplink port.

There is one point we missed the switch needs to be disconnected from the main to clear the mappings.

I'll take the switch and my portable in there w/ some cables later. Don't have time now

Hopefully this will give you the answer. Sorry I forgot about erasing the memory from the switch.

Yea, I agree with IronDuke, try another patch cable... that one is kinda sounding suspicious.

Make sure you have at least a CAT5 cable, I've seen CAT4 out there that look the same.

I've found the problem!! Well, let me re-phrase that. I've narrowed down the problem.

I took the switch into the laundry room. I unplugged the network cable from my server, and plugged it into Port 5 on the back of the switch. I took another network cable, and plugged it into Port 1 on the switch, and into my tablet pc. I disconnected from the wireless network so it would have to rely on the wired. I enable the wired network adapter, and it can't find an IP. I enter the information manually....and, well, I'm typing this right now, on my tablet, sitting on the washer in the laundry room! So I've narrowed the problem down to the cable going into that room.

Cable is just regular Cat5 going into standard wall jack I found at Lowes. I made another long Cat5 cable to go around the room, which I would thoretically plug into the switch. However, if I plug that cable directly into the computer it works fine. What do you guys say the problem is?


Thank you so much for all your help so far!!!
