Question about 3Com OfficeConnect TP800 8-Port Ethernet Hub (3c16722n)

1 Answer

Networking WXP Pro no IE connection or network capability.

I have elemenated the possibility of cabling The system has be checked by dell and for safe measure the system board has been replace. The nic is a broadcom 440 intergegrated controller 10/100. In the main location I have no problem with the system. If I take it to secondary loacation I have no network/IE connection and yet the system shows my network is up and connected. I have another computer at that location and it works fine on all ports in that office. The working computer does not use the integrated nic card but has instead a 3com Etherlink XL 10/100. The hub that this off-site uses is a 3com Ethernet Hub connecting it to the in-house site. I have been on line with Charter communications for hours as well as dell and they can find nothing yet it will not connect at the secondary loacation. What are the possibilities I need to disable the Broadcom and put in a 3com. Do you think I have a compatibility problem? Thoughts please. Thank you so much, Lotsip

Re: networking WXP Pro no IE connection or network...

Maybe a problem with 10/100 or Full/half duplex settings? Try changing them

I have just 2 computers currently connected to my Dell Power connect 2124...One is accessing the internet just fine but the other cannot acquire an ip.....I put new ends on the cable but stll no soultion

I assume you have connected your switch to any broadband router and then trying to access multiple systems at the sametime.
This is not possible if NAT (Network Address Translation) is not enabled on your broadband router.

Dlink Switch hangs all of a sudden

Sounds like a lot like you have a loop in your network... make sure you don't have a cable plugged into more than one port (ie a cable going from one port straight to another. If you have more than one switch and have linked the two switches together, make sure that you have only one link between them, otherwise this can cause a loop in your network and cause what is called a 'broadcast storm', which will cause the switches and PCs to be flooded with more packets than they can handle (you will see the utilisation of the switch rocket up!).

Hope that helped!

Just enable the DHCP capability of your DSL router and then connect the Linksys hub to your DSL router then your PCs to the Linksys hub.

Port speed issues with my DGS-2205

Gigabit swich does not enough for a Gigabit network, you also need to get your computers to support it, that means Gigabit network cards, buy if you don't have and you really need to, they are quite cheap these days.
If the above is not the case than it is barely possible, but worths a check, if you are using simple CAT5 cable instead of CAT5E or CAT6 (cable type is written on the cable, see for yourself)cable for the network?
If this is true consider doing a rewireing if really nessesary for speed, but cat5 is ok for gigabit around 10 meters distance for very good speeds.
However to do a little speedtest on your own first is not a bad idea at all, try to copy some big files between 2 computers and check the speed, 100Mbit networks used to do speeds about 8-10 Mbytes/sec that should do it for most networks, gigabit networks can do more, my record in my home network was 50-60Mbytes/sec, but mostly it's around 30Mbytes/sec.
Remember, better cable can do better speed and sometimes length affects network speed if the cable is very long (above 50 meters). And prepare, that you are not really going to reach the theoretical maximum speed of 125Mbytes/sec with common PC hardware. Maybe with some RAID based system or SSD can help you out, but most people don't really need that kind of speed.

Dell Powerconnect 2016 All leds are on, solid no blinking.

Had same problem with my Dell Pwoerconnect 2016, power it on and all LEDs light up but nothing works.
The problem was traced to one or both output capacitors ( 10v 680uf ) on the ( tiny ) power supply.
Capacitor symptoms include bulging or rounded tops instead of flat like new one and the rubber plug in base of capacitor protruding.
Capacitors need to be replaced.
I have successfully replaced with 10v 1000uf and 10v 1200uf, both Rubycon and Sanyo brands.
Power to the switch board is now restored and the switch is able to function just fine.
Give it a go and see if it works for your Powerconnect.

3 com hub tp4 home network setup failure

There are several possible problems here, and more information is needed to identify which one is causing trouble. First, are you using a high speed dsl or cable internet connection? ...or is your Internet connection a dial-up phone line? This will have a significant effect on how your cables should be connected between the hub and the computers. Windows typically defaults to a 169... address when it is not properly connected to a shared network connection.

Check the cabling. Could possibly be a broken pair in the cable. Make sure all ends are not damaged.
