Please help me, I'm going mad with frustration! Apologies for the lengthy post!

I have a Sky ADSL broadband connection, my own Draytek Vigor 120 modem and Apple Airport Extreme base station plus a pair of D-Link 306AV adaptors...

My iMac is upstairs, connected to the AEBS downstairs over ethernet, via the D-Link adaptor. However, I am unable to maintain a connection for more than 1-2 seconds, if at all. Very often the Mac would be allocated a 169. address, therefore unable to connect to the internet. Also, the mac would lose visibility of the AEBS via Airport utility. If I switch on wifi on the Mac, all is well in the world.

The modem is set up as standard pretty much, and the AEBS is set to DHCP and NAT mode. I have reserved an IP address to my Mac (reservation via MAC address) in attempt to dodge the IP address allocation issue to no avail.

What I have noticed is that the power line LED goes off on the unit upstairs (indicating it can't see another device of the same key pairing). This could be the issue, but I don't have another machine to test the wired connection from at present.

Just to confirm, wifi via the AEBS is perfectly fine.

What am I doing wrong?
 
Also, I use CrashPlan to backup remotely, but I haven't been able to connect for a while. I understand it uses port 443, I have tried to telnet to this and it is blocked.

Is it likely that my modem is blocking the port by default? The application is granted perms in the Mac OSX firewall menu.
 
Could be your electrical wiring being too poor for the homeplug adapters? Seeing as they're both on different floors, you might be in a home where the two floors are on different electrical circuits.
 
Yes its been standard for a number of years to use seperate ring main circuits for upstairs and downstairs feeds to minimize loading of the circuits and use seperate MRCB for each circuit. This could therefore be your problem.
 
Well I was using them with no problems for a few months with minimum issues so I'm a bit confused.

I'm going to test it downstairs using an old laptop.

Any thoughts on port 443 being blocked though?
