Powerline adapter suitability

Rotor

Hi everyone, I have poor wifi coverage in the parts of the house away from my router so want to get better coverage. Also have an outbuilding about 40m from the router I'd like covered.

All have mains electricity from the house but both would be on different circuits to the downstairs sockets ( that router is plugged to).
Is this suitable to remedy this ;-

And how easy is the set up? Does it require more than plug in and respond to prompts (sadly I'm a certified techno duffer)

Thanks

Oh I should add that the broadband speed here is very low so any limiting of top broadband speeds is pretty irrelevant

The 40m outbuilding may be a problem; a decent hard-wired connection is best (ethernet or even second phone line if its an office); TP-LINK stuff is adequate at best. Buy a pack with single wifi unit to try it out (should be fine in the house). PS. Costco (if you have a card) do the single wifi pack for less than £30 (£40 @Amazon).

Run an outdoor grade Ethernet cable from the router to the outbuilding and either plug it into the laptop/PC or install a WiFi access point on the cable.

Think along office/commercial lines, rather than domestic bodge job with WiFi extender or data over power line adapters. The result isn’t expensive and will be reliable.

Done about 30-35, using N class wifi, and got about 3MB/s. was clear line of sight and did do through a cavity wall. AC class wifi on newer routers is supposed to be a bit stonger.

I'm using BT 1Gb powerline adapters for both PC's and both BTTV set top boxes, works far better than the BT dual band wifi dongles we used to use. Price from the BT shop is silly, but I picked the powerline adapters up on ebay for £20 for 2!! The adapters need to be on circuits that are on the same consumer unit/fusebox/phase to work - which caused some amusement as for some reason this house has 3 phase power supply, so 3 consumer units (circuit breaker boxes), and the router and living room TV are on different phases.

I'm very wary of powerline gear, I and a few friends tried out several of the 200-500 era sets and none of us got a usable speed in our houses (I think the 500 set in one instance got something like 12mb and that was the best result*).

If you can get them with a guaranteed return as an option, or borrow a set from a friend try it, but I would be wary of paying £50 or whatever.

As has been said for the outhouse/garage if you can get some external grade cat5 that will give the best result.


*Rather amusingly that was on a run that went against the "best result" recommendation from the manufacturer (from an internal ring on one breaker, to a garage over armoured cable and onto a separate ring via a separate breaker in the house and a mini RCD fuse breaker box in the garage).
