Since our internet provider recently upped the download speeds for our subscription plan and then went and matched the upload speeds (before the latter had been at ~20% of the former), I recently ran a speed test - to realise that our internet connection was considerably faster (around 200mbps) than the connection from the router to my gaming PC (around 40-50mbps), which runs via Devolo Powerline adaptors with a supposed maximum of 500mbps. (I know that the maximum speeds given for those adaptors tend to be somewhat fictional.)
What I was wondering:
- Are there relatively easy ways of upping transmission speeds via Powerline?
- Would faster adapters (rated at, say, 1200Mbps) make a worthwhile difference, or are the limitations pretty much set by the flat's electric cabling?
- How easy is it generally to add - i.e. have an electrician come and install - Ethernet cables in a rental flat with existing cabling? Obviously I'd have to check with the landlord, but are we talking about something that's done easily and quickly?
Any information you can provide would be much appreciated. Cheers!

As for the other, if your landlord is amenable, it's easy, relative to regular power stuff since it's not having to be hooked up to a potentially lethal power source or anything. So it might be cheaper. There are electricians who do specifically "low-voltage" or data wiring.
It will still typically necessitate making holes in walls and stuff though, and you never know what you'll find when you do that.
