  • knownobounds Jan 28, 2009

    My wireless router works from this hub, however, none of the 1-7 ports
    work with any computer directly wired in. Is there some protocol
    or other set up required to use this hub?

Are you using the 10Base2 coax outlet, the AIU port or the 8port 10BaseT outlets? Also are you using port #8 which is an uplink port and not meant to be connected to another computer? This hub, although rather old, has auto MDI/MDI-X which can accept either straight or cross-over cabling on ports 1-7 and a switchable port #8. Just make sure your cables are pinned correctly. Otherwise, hubs are meant to JUST work. Although this particular hub MAY prevent/hinder DHCP requests (it does prevent DHCP type Boot LAN requests), which means you might want to try connecting between two computers who have a static IP address and are on the same subnet.

How to replace a wheel speed sensor

if abs [also speed] sensor is damaged better off replacing hub most sensors are incorporated into the hub or are a ring style that is a press fit around the hub and still have to remove hub to replace--- larger vehicles and some cross overs u can remove just the sensor not in your case --if just wire damaged can order and replace but if abs needs to be replaced than prior to removing wheel loosen center axle nut dont remove yet jack up and support vehicle- remove wheel,brake caliper,brake bracket,rotor and center axle nut ,disconnect abs wire connection and remove the 3 bolts at rear of hub and remove hub from spindle clean area and reinstall hub careful of wire connection replace all components

All hdmi connections not working on a samsung ue40c8000 every thing else seems to be ok. done a factory reset does this sound like a new board costly? regards. Norman

The tv Samsung refurbish main tv Turner signal board will set u back like $120-130 bucks + shipping and handleling and u must have to have some basic mechanicals skills like take things aparts and putting it back togther again to fixed this tv just for the used of those HDMI hubs ports again.My questions to u is?Does ur tv used 100% must require those useages of those HDMI hubs ports.Not just used the Samsung tv as is.My Samsung tv have the same problems.I just work around it by skipping all the useages of all those HDMI ports hubs of the tv altogther.Most poeple just used about like 3 HDMI ports hubs for like a HD cable box or DVR cable box and a PS3,WII games systems or Blu Ray DVD player.All these devices can go through hook up for like a RCA component cables hook up like AV1,AV2 and last one a HD hookup by a RCA component cable just add 2 more components wires like a green and purple connections or just buy a set of RCA components cable that design for a HD output.I did that,must more reliable set up too.Because those RCA components cables set up have more plastics in it connections for insulation holes for little shorts and sparks better than those HDMI ports hubs and HDMI cables barely help and the plastic for insulation is a joke almost non exiten.Those all dam HDMI ports hubs are all link into one path way on the circuit board,one dies or got shorted all dies and get shorted out.

Changed the battteries and mouse and keyboard. Now can't get keyboard to work.

There is a central antennae that hooks directly to the computer via USB plug...on that central hub is a button, this is a component connect button, push the button on the antennae first and as it is blinking, push the connect button on the keyboard, it may be green in color and you may need an ink pen to depress it....just make sure that you depress it while the other unit is still blinking. This will connect the component to the hub. If you follow the procedure and it does not immediately connect, reboot and perform the procedure again.....try to move the hub to another usb port before you power back up.

Power surge on hub port

Try this to find out which one of your components has an issue. Turn off your machine then unplug all of your USB cables. Turn your machine back on and plug in one of your USB cables. Verify the component you just plugged in works correctly and if it does plug in another cable and verify that component is working. Continue these steps until you have the one component that displays the error you have seen. That component is most likely the cause of your issue and should be replaced.

Good luck, Greased.

How to Connect HDMI Components with AVR 3805 as Hub

In reference to the comment you added to our chat session:

Just connect your receiver to your TV using the same cable your receiver is currently using to connect to your TV, be it Composite, S-Video, or Component. Just switch your TV to that input when you need to set-up something on the receiver.
