Solved Can't connect ethernet switch to NVG510

August 25, 2012 at 18:35:54
Specs: Windows XP
We have a network in place. A week ago we switch to AT&T's UVerse and they replaced the Motorola modem with a Motorola NVG510 modem/router. There was a Netgear router behind the original Motorola but since we only needed 4 ports I pulled that out of the loop and used the Motorola. The three computers connected directly to the Motorola came right up. However, there was a switch with two computers connected to it and when the switch was connected niether of the computers connected to the switch would go to the internet. I took one of those off the switch and connected directly to the Motorola and immediately connected to the internet. Put it back through the switch and nothing. Any ideas? Thanks...

✔ Best Answer
Have you done a power reset on both the modem and switch in sequence?
Power down all devices. Power up the modem/router then after it has settled power up the switch. This will allow any auto-adjusting ports to accommodate themselves to whatever type of ethernet cable you have between the modem/router and the switch.
Rule of thumb is Like devices require crossover cable. Unlike devices use Patch.
Modem & Switch are "Like" devices. Switch & PC are "Unlike"

Not all modems, routers and switches have self-adjusting auto-sensing ports. If you do not have devices with self-adjusting ports you must use the appropriate type of cable. If the ports are self-adjusting they can only do so following a power reset.

That may be it. I ran into the same problem a few months ago with another customer. Problem is the cable is about 100' long and is run throught the wall. Odd however that the Netgear router had no problems with the switch but AT&T's Motorola router does. Maybe I'll look for a self-adjusting switch. Thanks...

You can also get a patch/crossover adapter plug to fit to the end of the cable rather than purchase a new switch.

Or I can just clip the ends and pin it out myself. That's if I can find my RJ45 jacks .Thank you very much for you help.
