Problem linking netcomm NB5540 ( uplinking ) to a 8 port switch.=(

[ray_z123]

Hello:)
I’ve recently purchased Netcom wireless/router Netcomm NB5540, Due to the limited 4 ports of Ethernet connections on the wireless/router I recently purchased a 8 port Switch. My problem is linking the wireless router to a switch, what happens when I attempt to do this is: the indication of the link flashes on and off (similar to the result of a network cable being plugged in and out of a switch/ The switch is not faulty I’ve tried linking 2 switches without any problems).

I do hope to hear from you soon


:D
The user manual that i recieved with the product is located here:

(last link)

I’ve refered to the manual for aid on the manual on page 37 static routing, but I was unsuccessful in doing as I was confused with the configuration (as the case study used a router.. while iam using a switch)

Thank you for your attention!!! :)

regards

I guess you have been through the links by now. I think perhaps you are confused by the description of your NB5540. It is a router and a switch in one box, the router connects one port of the switch (an iternal one) to the outsied world. You are trying to connect another switch to a port of the NBB540 switch. Switches don't know about IP routing and such so routes, static or otherwise, are a red herring.

Your problem is most likely caused by physical connection. If you will forgive me teaching granny to suck eggs it's like this.

The output one of device needs to go to an input of the other and vice-versa. So if the sockets are identical and the wire goes pin-to-pin then it won't work. Usually cables are straight through, pin 1 to pin1, pin 2 to pin2, etc but the sockets on a repeater (be it a switch or hub) are different to those on a PC, so it all works.

To connect a switch (or hub) to a switch (or hub) you need some means of transposing the input and output connections at one end. This may be by means of an "uplink" port, a port with an uplink (or crossover or X-over) switch or a crossover cable. A number of modern switches negate all this by sensing what is going on and automatically crossing over as requred.

I hope this helps.

Hello thanks for the replies, i've tried cross over cables etc, still doesnt work i've tried many combinations e.g port 1(wireless router) to port 1 (switch) and port 1 to uplink(another switch i have that has a uplink port) any other combinations (tried cross over cable already) still doesnt work...

I guess i can assume that the ports are faulty, i've tried plugging a cat5 cable to the wireless router and plugging it into a computer i dont recieve "status" that there is a connection..

If you can not get the wireless router ports to work with any other computing/networking device, then it is probably faulty.

Hi,

Make sure your router has auto negotiation (Auto-MDI/MDI-X) for your ports. If your router does not have auto negotiation the only way to connect two switches is to use a crossover cable. Also check your cables.

Remember that a wireless router connects two ways: wired and wireless. 1. Connect the cable from the router to one of the ports on the switch (not the uplink port).
2. Connect the cable from the router to the desktop directly (by pass the switch).
3. If you have a wireless desktop/laptop connect it to the router via the wireless adapter card.
4. Isolate the problem by attacking it from two sides
5. Router maybe faulty
