Think of it as a local five-port switch. One connects the PLC, one connects the wireless AP, the remaining three are on the RJ45 cable jacks. Your real world performance largely depends on how good...

First you should figure out what exactly disconnects. Does the PC lose the wired connection to the 8030, does the 8030 lose the PLC connection to its partner on the router, does the router lose the...

Why would you even want to do that? Use a powerline device with integrated WLAN function, and set that up to copy the SSID and passphrase of your original WLAN.

Then connect to one of the 8030P using the tpPLC utility, and manually add the WPA422 by entering its ID code and then plugging it in.

Obviously one does not make multiple connections from the router into the powerline network. One PLC connects to the router with one cable. Then go pair all the PLCs into one single PLC network. Then...

Physical line speed can go up to 500 Mbit/s in perfect conditions. 233 Mbit/s in real life is reasonably good. Now, as with any shared-media connection, payload throughput does not come near physical...
