|Not sure if this has any bearing on your situation but Devolo (in Germany who I think pioneered this system) advise "not" to plug homeplug adapters into long flying lead extension power bars etc. (the sort that are a single lead feeding two or more outlets) but to go straight in to a wall power outlet directly. This to apply to all adapters. They suggest signal attenuation can be significant when using power bar extensions...|
My own experience has occasionally seemed to support their view, but not always.
Also, although most homeplug adapters (regardless of manufacturer) allegedly work straight out of the box - and that has been my general experience - i have found it useful to run the basic software that many arrive with. Devolo provide a utility which in effect registers each adapter, allows to accept the default encryption key, or to redefine that key. I have found that utility useful once or twice to resolve an apperent dropped connection event via a given module/adapter; regardless of the encryption aspect.
I have a printer that is accessed over homeplugs - one of which connects to a D-link parallel port server. The printer is upstairs (former study/office). Most of the time it works fine - connects and the data trf to server is max...; and then suddenly and for no detectable reason it will fail to connect the D-link to the lan, at the least suddenly drop significantly if not actually lose connection. Substitute another homeplug in the same outlet - no improvement. However use another adapter or another outlet (just outside that study/office) and it will work perectly and at max speed and no drop off etc.
The two outlets are on different ccct. breakers, and the study cct. Is not on the same
fusebox as the one just outside that room. That other "fuse box" includes an RCD/GFI - while the study one doesn't... Whether or not it is RCD/GFI which impinges here - not sure; but based on discussions here recently, and my own experience I am inclined to think it does... Though why sometimes and not others?
Also I am wondering if it's a router issue... I have ip addresses for all my network devices, but of course that doesn't apply to the any of actual homeplug adapters.
You reboot your laptop and all is well; that hasn't ever worked for me. The "study" connection will work OK or not as it pleases... Occasionally pinging the server ip address will sort of resolve it, but not always. The "situation" is independent of which computer - Macbook, MacMini, Acer Windows laptop - is involved...
