I have an issue with an Addtron AES820TX Hub. The device is passing traffic, but I am unable to ping the IP address that has been assigned to it. This occurred out of the blue about 10 days ago. Tried rebooting it, and still it will not respond to ICMP, yet continues to pass traffic. Any thoughts other than perhaps the device is just faulty?
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.
A 6ya expert can help you resolve that issue over the phone in a minute or two.

Here you will learn network troubleshooting tips, fix tcp/ip errors, tcp/ip settings, internet connectivity errors, how to fix pc errors, lan connectivity issues, traceroute and ping commands. Whether your operating system is Windows or Linux network problems are likely to arise. Many times the network problems arisee due to improperly configured TCP/IP settings. Following is the basic checklist to identify and troubleshoot the basic networking errors. 1. First of all you should learn what stopped working server or client computer also see if the outage affecting the other computers or only one. 2. If you server stopped working you should inform the users of the server and you should start working on fixing the error. 3. If a single client computer stopped working or disconnected from the network, ask the user of that computer that what recent changes cause the server to stop working such as newly installed software or games, service packs, internet software, new hardware or any other thing. 4. Check the physical network connectivity. The most network problems arise due to the physical layers failure. 5. Check all the network cable connections. You can start at the NIC and check if the green light is blinking then check the hub and see if the computer is getting the link across the cable. 6. Get a cable tester to check the connectivity of the cables. 7. Finally start pinging the network both Windows and Linux have the PING command. You can use ping command in this way start > Run > cmd > type "ping" then IP address of the other computer
ping the face book site that is go to the DOS prompt and type ping www.face book.com this will give give 4 replies back if the site is responding. If not then you have a firewall issue or a DNS (Domain Name service) issue. Ping this ip 126.96.36.199 if you get the site with this then there is a problem with the DNS.
Wich kind of problems, you are unable to ping the copier or you cant print, or ...
If you connecting the PC directly use the croswired cable if you are connected over HUB, or other network device you must use normal UTP patch cable, from copier to the HUB, and from the HUB to PC.
Do you have right IP, subnet and gateway?
Check the network cards on copier and PC, if you crimp the cables by yourself check the cables,...
Do you have printer FLASH on your copier?
When did errors occured? Were you able to print before?
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.
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.
If I remember correctly, this device has vlan. Did you check to make sure that the vlan is configured or turned off? And does this have a firewall? Seems like a firewall is blocking ping port but allowing traffic.
Also, I thought the 24WM was a 24 port switch, you mentioned a hub, but what kind of hub is it?
It really sounds like a port blocking issue.
Port forwarding and static routes isn?t the route to go down to fix this issue. I have an FR114 in a similar configuration and yours should work as well.
-When connecting a hub to a router you should be using a certified, standard Ethernet cable, not a crossover. Make sure it?s certified for at least 100 Mbps.
-If you are using port 8 on the hub to connect to the router make sure the Normal/Uplink button is set to Normal.
-Are the Link and 100 Mbps LED green on both the hub and router ports you use to connect? If not try a known good cable; if that doesn?t work try different ports.
