I would try a different port with a new cable. IP conflict should be noted by the PC / node. You could ping the IP in question with the -a switch to resolve DNS name. You could also run a traceroute from the command prompt to help identify what drop if failing / timing out.

SOURCE: Need Driver: Aopen Ethernet mini Hub AOH-528

Hi joshua,
1.For a hub you don't need any driver.Just simply plug anything onto it.

2.I think the error message being throw by you computer was
"conflicting IP" not "conflicting ISP" .So if incase of "conflicting IP" that mean you have more than 1 computer using same IP number.So the solution is to change the IP number so that they don't get conflict.

3.make sure you use the same group of IP.like if your first computer is 192.168.0.1 then your second should be 192.168.0.2 and so on...3,.4.,5.....

Bye,takecare.

SOURCE: Network Conflict issues

Hi,

So your basically connected straight to the internet,

This is your connection problem already, too many systems...

use the router as a gateway only, not for D.H.C.P.

all systems should be behind a router, especially the servers, these should be well away from the net, at least behind a firewalled router,

Promote the server to Domain Controller
install D.H.C.P. on it

If you have file servers thats ok, just connect them to the network.

( you will have to go round all PCs to change to AUTO D.H.C.P )
This is a saturday job for you when no one is working.

let the server handle D.H.C.P.
thats what it is for, exactly for your problem you have,
of a Growing LAN, yes 10-15 PCs is ok
but now 35, possible going upto 40-50, needs Automating.

Hope this helps

Richard.

SOURCE: how to connect two 8 port dlink switch?

You have to interconnect the switches with the cable. Connect the computers to the switches. Also connect the internet cable in the switch too.

SOURCE: lost connection between switch and hub - LED flashes every 5 secs

You say you have the same problem when you connect the cable directly from router to laptop, so it apparently is not a hub problem. That leaves the router and the cable. You're fortunate in having a working system on the other port. Why not try swapping pieces to see which is the failed piece? For example, what if you swap the ports for the cables? If it's a router problem, then the "bad" cable should work when in the other port. What if you swap cables? That would reveal a bad cable. Finally, swapping computers would show a computer configuration problem, such as the connection not being set to automatic.

SOURCE: We've got the Dlink DES-1008D setup in our office.

Ok, the next time when the disconnection occurs. Try the following:

Open command prompt. And try pinging www.google.com, if the ping is successful and you are still unable to access the internet, then you may want to check the proxy settings on your web broswer, or possibly repair/reinstall the browser. You can also try accessing the internet on a different browser.

If you are unable to ping google successfully, then try to ping the IP address of your wifi modem, this is your default gateway. If you are unable to ping this address successfully, then check the cable from the DES-1008D switch to the wifi modem. As a local area connection 'connected' just shows that the link from your PC to switch is fine.

Please try these steps and let me know the results.

Regards..

Your company has just moved to a new office building. The server has a fiber optic network adapter, but the building does not have fiber optic cables installed. How do you install a media converter?


100BaeFX to 100BaseTx media converter. ST to SC cable.

SCA connector goes to the RX port in media converter.

STA connector goes to the TX jack on network adapter.

SC male B to TX port on media converter.

ST male B connector to the RX jack on network adapter.

Connect media converter to network with Cat5e cable which uses RJ-45 connectors.

I face a problem to connect a to office with a 95mtr cat5e cable.switch is not blink on both hands.


95 meters is simply too long. No way of getting a signal on the other end without the use of a repeater. The maximum distance for CAT5e and CAT6 is 295ft, which is roughly 90 meters, but even that only works in an ideal environment. Often the max distance is announced with "300ft = 100m", but that is not true (and 300ft are only 95 meters anyways.)

The best option is fiber optic cable, but that is very expensive.

Read also this article - it has some good explanations and comments.
I would buy a cheap router (WRT54G i.e.) and modify it with some third-party firmware as repeater. That would cost you not more than 25-50$. (Tip: google "Router as Repeater", and you will find many results.)

If you have any more questions, just come back here and leave a comment - I'm happy to help.

Amber lights on a Cisco switch.


It sounds like you have loops in your topology. Loops will cause the LAN to crawl.

Amber, on a Cisco switch port means that a port has been blocked either as a security violation (if mac-address security is being used) or by spanning-tree protocol which shuts down ports involved in a network loop.

Check all your wiring carefully...especially the fiber-to-ethernet converters. If anybody has a hub or switch under their desk make sure they do not have two ports from that device patched into two ports in your cisco switch.

From Cisco catalyst 3500 user guide:

Solid amber

Port is not forwarding. Port was disabled by management or an address violation or blocked by Spanning-Tree Protocol (STP).

Note After a port is reconfigured, the port status LED can remain amber for up to 30 seconds as STP checks the switch for possible loops.

Slow internet.


Your hub can support more that fiber optic puts out. Problem might be a slow computer. Run a internet speed test see what it gets through hub and then straight to the computer bypassing the hub. If possible. If there is a big difference either way what ever is slower is most likley the issue.

Canary CFT-2062 connection diagram


I tried to answer this for you yesterday but FixYa didn't put it through I guess. I'll try again.

That device is a "Industrial Media Converter". It is for converting a 100BASE-TX LAN cable into a 100BASE-F fiber optic cable for long-range networking. (2km) There are two ways to use it.

One:
Get two and convert LAN to fiber, then back to LAN.

Two:
Use it to tap into an existing fiber network, like fiber optic Internet.

For the first case; you will need some "Duplex" "multi-mode" fiber optic cable ($1.10 a meter) and an other one of those devices ($50~$300).

For the second case you will also need some fiber optic cable and you will need a network to tap in to. Of course you will need to clear everything with the company that owns that network before you can do any thing. And that’s assuming that they even use the same system level protocols.

To directly answer your question:

1: Hook the 100BASE-TX LAN port up to a PC, Hub, or a switch.

2: Hook up TWO multi-mode fiber optic cables to the device using CT style connecters. Hook one to the TX and one to the RX connectors on the unit.

3: Run the cable how you see fit.

4: Hook the other end up to the interfacing device. Be it joining it to an other cable in an existing network, or to another of those devices.

Note: The TX cable of one device goes to the RX of the other and visa-versa.

-Charlie

P.S. I also have one exactly like that one that I’m trying to find a use for.

You must configure the other PCs in the same IP range of the netgear. fexample: if the netgear ip adress is 10.0.0.1 then the other PC should have an IP like 10.0.0.x (x = any number from 2 to 254)
