Homeplug ping spike problem

[Yorkshirelion]

Hi all,

Just got a Netgear HDXB101 200Mbps starter kit, plugged it in and installed the software which was a piece of cake, however the reason i bought these was to cure a flaky and packet lossy (made up word) problem.

One is connected to my router downstairs, one is connected to my PC upstairs, when i ping my router downstairs i can ping spikes as follows;

Is that just interference on the wiring that is causing this ?

If anyone else that has some could test there's i would appreciate it

I got these using 85Mbps Zyxel HPs. The spikes, coincidentally or otherwise, were when our daughter phoned us on our DECT phone.

Damn,

It would seem that these are not the solution to my network problem then

I'm out of options, can't run Cat 5, wireless is lossy and these have big spikes, i wouldn't mind if it was just the old 10-20ms but i have seen 300-500ms and that is gonna cause a lag issue for sure.

Im afraid theres just as much noise on the powerlines in your home as there is in the airwaves

powerline uses a lot of algorithms (just as 802.11 wi-fi does) to overcome this and can be a lot better in some circumstances, just not all.

Some things are very noisy on the wire - switched power supplies (like those that come with mobile phones) and transformers (some low voltage light fitting ones) are the worst offenders, so try not to plug these in anywhere near the homeplugs
