An Addtron AEF-1004 network hub has landed on my desk. When powered up, the LEDs indicate power on, collisions occuring, ports 1 and 2 connected to kit (when nothing is plugged into them) and activity on port 4, activity that isn't happening. Is there a way to reset this box, or is it - to use the term correctly, buggered?
You have a real beast screwing around in that hub. You have choises:
1. Call the animal control department :)
2. Shoot it with a 22 :):)
3. Get another one.
A Hub acting like that has got its marbles juggled. Switching it on and off is the only way of flashing, and if that doesn't work, its jinxed. If you network it, you could spend a lot of time fixing network problems.

You do what you are describing, attach the hub to the router in any regular lan port. Then just plug everything you need to into the hub. Make sure dhcp is on on the router (it probably is) and just set it to automatically obtain the IP on the computers attached. The router can go through the hub (or switch) to give them IPs.
If your PC LAN Card is active just connect the switch with Straight cable - & --you will see one yellow box in ritht side corner down to monitor screen...where the time appears.....also you can check in the Network Connections Folder. Or Right Click My Network Places> Properties> You will see local area Network....> Connected...then it is working if disconnected it's not working....Good Luck
When the computers are powered up and connected to the D-Link hub, the computers that are connected to the hub will light up the various LEDs on the hub to indicate which port on the hub is active. Also that computer's network card Link LED light should be on to indicate it is connected to the hub. If the hub's LED is off and the corresponding computer's network card Link LED is off then the network cable is faulty, or the network card is faulty (or the network card driver needs installing) or the port on the hub and/or hub is faulty. To determine which item is faulty, swap network cables around, swap computers to different ports on the hub etc
Capacitor C2 on power suplly board will probably have dried out. Should be 47uf 25Volt electrolytic, mine measured
I have replaced this capacitor on 3 of these units and all have come back to life.
The LEDS blinking normally would indicate reset internally or when the unit has just been powered on. Continous LEDs lighting up or flashing with or without a connection is an indication of extensive hardware failure. This could have been brought about by a near lightning strike, a power surge or simply component failure. Unfortunately the repairs is not economically reasonable and therefore a replacement might be better off. Sorry.
Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.
Is there any change in the configuration made, like is ICMP blocked. If youa re bale to pass traffic without any issues and if the issue is just that you are not able to ping the HUB there is a posibility of blocking the ICMP requests.
