as I said before the only real way to find out if they work is connect and see if they affect your connection speed then look for alternatives - but try them first
I have continued to use the powerline adaptors but mainly because i don't have (yet) any alternative as none of our desktops at home (which i assembled) have WiFi adapters / dongles. I experienced dropouts during the first 3-4 days but it has been fine ever since.
Broadband speed has been playing between 100-250 Mbps which may be fine, but very inconsistent and has yet to realize the 300 Mbps which i am paying for. I can not ascertain if the homeplugs are causing any issues on the Ultrafast router because I haven't checked performance without them.
What I'm confused about is that the Openreach Engineer was certain that the homeplugs / powerline adaptors are fine to use with the Infinity smarthub routers, but NOT with the ULTRAFAST router !!!!...
In fact some of the of the answers here claim that it should be the other way around, i.e., the G.fast FTTP setup should not be affected.
Any more ideas / explanations please ?
Which is delivered by copper and thus susceptible to interference, whereas FTTP is completely fibre and therefore totally immune to interference.
But that doesn't explain what the Openreach engineer said... which is that " homeplugs / powerline adapters do not affect Inifinity routers, but affect Ultrafast (g.fast) fibre ".
Thanks. You meant question 5 though, right?
I had a good chat with a knowledgeable guy from BT ultrafast repair team a while ago, and i was told that the powerlines would not have any adverse affect on the G.fast bandwidth data track coming from DSLAM, (if there is poor electrical wiring in the property, the powerline / homeplugs will not be effective).
