  • Installed a hub and now my dsl upstream went WAY down, can someone help..

    Yesterday I bought a linksys hub, 10/100 nic cards and cables and networked my two P3 systems together. One system is running win 2k and the other ME, my dsl speeds were about 450 down and 230 up and when it goes thru the hub my down speeds stays but my upstream went to 24! Any ideas on what I might need to do. Here's my setup: the gateway that controls my dsl goes into my hub in the uplink port and then the other rj45 cables goto my 2 computers out of the hub in slots 2 and 3. Any ideas? Thanks

    The hub may have this effect since it forces your computers to share the total bandwidth of the system (as I understand it). Also, a hub requires your ISP to assign one IP address for each computer. You may be limited to one IP address by your DSL ISP. They may give you trouble if you consume more than one address.

    The optimum (cheap) hardware to connect your pcs is a DSL router, such as the Linksys BEFSR41:

    Personally, I recommend the Zyxel Prestige 314:
    http://www.zyxel.com/html/product/wan/p314.html

    Both are available at Buy.com. They provide a firewall and connectivity between your computers in the form of a DHCP server and 4-position switch which is faster than a hub (active instead of passive). Also, they use only one ISP address.

    I'm relatively inexperienced with this stuff, so others may have more informed opinions.

    The reason I recommend the Zyxel router is that it gives me little or no problems. I returned a Linksys BEFSR41 router because it was dropping my connection through PPPoE. At that time this was a weak point with this router (as stated by their tech support). I don't know if they've fixed this or not. As I understand it, it was only a problem with the PPPoE configuration. Not everyone had a problem.

      Brian- The dsl I signed up for says it supplies 2 ip addresses and I set both to auto detect ip and they are different. I can't imagine I would need to buy yet another piece of hardware to make this thing work but maybe so. Thanks for the response.

        The 2 IP issue must not be part of your problem. Maybe you can return the hub for a refund. The DSL routers also provide a necessary firewall function.

          Are you sure that all the wires you are using are good? I've seen transfer rates shot to hell by wires that are too long and/or low quality. What's packet loss like?

            Wombat- thats a possibility, i'll check my cables. Two really long ones came with the kit I bought and I already have 3 other short ones so i'll switch them around. How do I check packet loss?I'm using win 2k on my main system. Thanks

              Kookstick as long as the wiers are under 50m you should be fine!

              EDIT: Oh you are from USA 50m is ~150feet

                I don't know what you would use in Windows. And I've seen a 50ft cable cause huge problems when a 20ft cable fixed the worries.

                  Well, I have a 125ft cable to a computer all the way on the other end of the house, on another floor, no problems.

                  Try disconnecting one of the computers and see if the upstream is still bad. You could also try connecting one of the computers directly to the DSL modem.

                    Is your ADSL meant to go into your uplink port, or just a normal one?

                      Err... see... there's a twisted vs. non-twisted issue here. My cable modem requires a twisted wire to run from the modem to the PC. HOWEVER, when I run the modem into my switch, it HAS TO BE a non-twisted wire or it just won't work.

                      So you may be better off switching wire types and going into a standard port.

                      Or get a switching hub.

                        Get a cheap $50 LinkSYS switch from Buy.com. You response time wil go back to normal. Worked for me.

                          you may wish to check to see if your dsl provider uses collision avoidance or collision detection...detection only will interfere with your upstream performance because it will stop and start the data flow whenever both systems are in use...the downstream will maintain because it is not bottlenecked by the modem. I think this may be one of the more annoying limitations of the PPOE protocol...

                            Ali- I believe it has to go in the uplink because it wont work otherwise, it has a gateway which I guess is some kind of modem.

                              could someone explain the difference between hubs and switches because they seem to do the same thing, yet the switch is faster at doing it. Why use a hub then? Maybe I will return it all for a refund and get 2 better nic's and a switch instead.
