Topic # 112270 3-Dec-2012 13:27 Send private message

Hi,

I was wondering if people could please give me a few pointers to troubleshoot some internet/network issues I'm experiencing in a house I just recently purchased.

I have Orcon ADSL.  My network is both wireless (for two iPhones and one iPad) and Ethernet over power for two desktops, a HTPC, two Xbox 360 (used for Media Center extenders), and one PS3.

The Orcon Genius router is on the top floor next to the phone outlet.  The HTPC is also on the top floor, with one of the Xbox's on the floor directly below it in the master bedroom.  Performance (network, not internet) seems to be very good.  On the same floor (it's a three story place) are the two desktops.  Internet to them is very flaky.  On the ground floor (in my mancave Smile) I have the other Xbox as a Media Center extender, and a PS3.  Network performance to that Xbox is poor at best.  The PS3 hasn't had much attention thus far.

Most things point to poor network performance, but the internet doesn't seem 100% either.  What steps can I take to try and pinpoint where the issue(s) lie?  Are there some basic tests I can do?

Any help would be appreciated.




Cheers.

The Ethernet Over Power seems to be your problem then.... try removing some of those devices from the network and run a test - any better ? Yes, then start adding the devices back in again until the issue rears its head again... if it does before plugging in all your devices, then the last device is causing an issue on the network.

If you have no change after unplugging devices, then Id suspect its some issue with the EoP or even your power cabling....

Got a long CAT5 cable ? Try it as a test...

Are you suggesting that maybe one of the EoP devices is not working correctly?

What sort of tests can I run (sorry, a bit of a noob in this area)?  Is there any way to test power cabling?

I Argree with XPD.

For basic testing you can use "ping" from windows command interface - Click Start , type cmd in the run box and hit enter, in the command line type -> ping x.x.x.x (X=IP address of each device check your router for the IP Range), do this from the pc on the top floor. You wiil see how long it will take from the top floor pc to send a packet to the client and back. And try and do what "XPD: posted : and continue with ping test, see if the reply back from the client improves.

ETHERNET is always a good reliable option.

Oh as for the power cabling test, this is easy, if the outlet has power, the cabling is good, EOA is the device which extracts the traffic from the power line, 9 out of 10 it will be your EOA Device.

Hi Satch

Have you tried a device attached by Ethernet directly to the Genius router?  How is that?  How about the Wi-Fi devices?

Cheers

Llory: Oh as for the power cabling test, this is easy, if the outlet has power, the cabling is good

If thats the case, we should probably disband these guys then. Totally unneeded.

However, in reality, presence of sufficient current is not a reliable indication of the quality (or safety, or reliabiilty) of any power cabling (whether that's for power supply use or otherwise).

As per above recommendations, isolate all networking devices down to ethernet cables (not over power) only, then start adding non ethernet-cable links in one by one, and testing for issues.

And apparently some electrical components are not very good at passing data signals through them. I would try installing some Ethernet cables at least around your top floor or put the modem on ground floor and find a way to get ethernet from there to upstairs. Might not be easy since you have already gone to the trouble of getting the EoP setup, but Cat5e (or better) cable is reasonably reliable if installed properly.

RCD breakers seem to kill any carrier signals on them. Unless the ethernet over power is on the same breaker you are already pushing stuff uphill with a broom getting them to work.

Thanks for all the input so far guys. I'm extremely busy at the moment so won't have time to test a few things out until next week. Will let you know how I get on.
