Recently bought a Devolo DLAN200 AV Wireless N Starter Kit. Set up as instructed. Took a while to work out my router settings. The kit now works but is extremely slow to download from internet. Wireless signal is fine. But whether I connect to the wireless, or connect to the ethernet port of the Devolo adapter, it is very slow. Via ethernet, I can get to a speed test site, and it shows less than 0.5Mbs. This compares with 6Mbs if I connect to the router's ethernet or wireless. I have tried other settings on my router, including all combinations of channels, but there is no improvement. I have tried other plugpoints around the house, but no difference. Devolo support on the phone was no use. Can anyone help?
