Powerline trouble

I've been tearing my hair out trying to find a solution to this but had no luck searching online so decided I'd try asking on some forums, I recently purchased a TP-Link TL-PA8010P (v1) Kit to link my PC upstairs 2 floors to the Router downstairs, I paired both the links as instructed in the box

http://uk.tp-link.com/res/down/doc/TL-PA8010P_KIT(UK)_V1_UG.pdf

Bother powerlines find each other and all the LEDs on the side are solid green, the PC detects it's now connected to the router and the internet, the moment I try to download something or join skype the router somehow loses the internet, LEDs on the router go from flashing green to nothing everything goes off except the power and ethernet, not just the powerline connected pc but the wifi too and I cannot find anything on this problem most posts are about the powerlines disconnecting from each other none about killing the internet.

I've tried
-Updating powerline firmware
(this has temporarily fixed it for an hour or so)

-Moving the router do a different power socket
(the router https://sales.talktalk.co.uk/product/fibre/superrouter)

-Using different Ethernet cables and ports

Currently gone back to using wifi and the internet doesn't end up killing itself, any help would be greatly appreciated

I'm not familiar with the router but does it provide any type of system log you can see through the admin interface that might reveal more information as to why the internet died?

If not then see if you can borrow an alternative router that does have the facility and see what happens when you try and use the PC on the other end of the powerline.

I'm wondering if traffic between the powerline adaptors, or mains-borne noise from the adaptors themselves, is being seen as interference to your router and causing it to lose sync. The frequencies that the homeplugs generate probably overlap nicely with those used for ADSL/VDSL.

Are you are able to connect via ethernet cable direct to your router and monitor the noise margin with and without the powerlines plugged in / in use? It would help confirm that it's definitely the powerlines involved. If the noise margin takes a dive and/or the router loses sync then a few possibles may be:

- faulty router power supply - not filtering out and sufficiently immune to mains-borne 'noise' properly
- powerline traffic causing excessive noise on incoming phone line to router (coupling from non-twisted pair telephone extensions running alongside mains cables?? dodgy filters?)
- faulty homeplug that generates mains-borne noise/RFI (try swapping them around?)

Edit: found this which suggests a minimum 2m separation between homeplug and router:

Run a cable

I've tried running a cable to a laptop and it works fine that way no disconnections, I cleared the logs on the router and set them to debug level, this is what they showed after connecting the PC to the powerlines and I tried running a speed test it doesnt' even make it to the upload before disconnecting.

Attached log https://www.dropbox.com/s/ylc6as7ix9sfe7m/syslog.txt?dl=0

I mean permanently run a cable, get rid of the powerline adapters.

Not possible, renting a single room and they don't want cables running through the house, if the logs don't help I'll send these back and try a different pair.

I'm 2 floors up from the router.

Tried plugging in the router on opposite side of the room to the powerline and still had the same issue, as soon as I started using it the internet dies

Are the sockets on the same ring ( breaker ) on the fuse box? if they arent then that will be the problem and its likely no brand of adapter will work well.

I am lucky that mine are and i still get the odd random drop out. Powerline adapters are ok but not perfect, and no where near as good as a proper cat5E cable i am afraid.

The fact you are 2 floors up most likely means they are not on the same breaker so you are plum out of luck.

I have homeplugs on 3 different ring mains and they all work without issues.

Them not working isn't the issue here. If you read the OP it's a problem with them knocking the router out.
