Hey guys,

Basically have my ADSL modem downstairs as that's where my dedicated DSL jack is.
I am using ethernet over power to get a connection upstairs to a Linksys WAG120n which then connects to my computer.

Randomly every 1 - 3 days, I get no internet upstairs. Leaving the powerline adapters and the adsl modem off for about 5 minutes fixes this issue. I have tried plugging the powerline adapter directly to my pc without going through the wag120n, still the same issue.

Is this something to expect with ethernet over power ?

Modem downstairs is a TP-LINK TD-W8960N.

My ethernet over power adapters are the TP-Link TL-PA211 .

I'm using (in total 5) Netcomm adapters and don't have any issues with them, seem to work quite stable. It also depends on your house wiring more than anything, plug the EoP injectors straight into the wall if possible avoiding any surge protectors since these really mess with them.

Could be possibly worth using something like a WRT54GL to do a wireless bridge?

They are plugged in directly, hmm weird. Probably my crappy house wiring.
Its not an old house, but probably bad wiring i guess.

Have you upgraded your Firmware on your modem? Also, if there is a Firmware upgrade on your EoP adapters, do those as well (Just look on the manufacturers website)

I would start by looking at the homeplug adapters.
There will be three lights
1) Power
2) Homeplug connection - sometimes changes colour
3) Ethernet connection

Specifically look for light number 2. It will light up when the homeplugs have paired with each other.
As it drops the speed, the light may sometimes change colour. Eg. Red = 20mbit Yellow = 50mbit Green = 85mbit
If the light goes out completley when the internet fails then you know there is a problem with the connection between the two homeplug units. Often it can be interference from transformers inside appliances that is putting noise back into the power supply in your home.

Other times, it can simply be a borderline connection and it only takes a tiny bit of interference to drop the connection.
To solve this its just a matter of moving them closer together. Remember the wiring between rooms will go from one home plug to another via the main fuse board. So sometimes moving one of the homeplug units to a power socket further away (in some houses) can actually move them closer together when you look at the wiring path distance between the two.
