Welcome to Vodafone Community
I've found the TP-Link powerline extenders useful where walls are solid in the past. They also offer a convenient way to extend ethernet cabling options if you want.
Thanks for the advice. I am pretty sure these don't work that great due to the wiring - we have had 3 extensions so the wiring is safe and approved but probably not as expected. I tried these when we had the original Vodafone router and they were no good.
Then I’d leave the router in place and invest in a good wifi extender; unless your place is huge in which case google nest mesh WiFi looks like simplest option . I trust Tom with his reviews re standard extenders:
My son who is a very competent electrician has installed an Asus Mesh system in his house which is substantially bigger than ours and since doing so he states his coverage is much better and the signal is consistently stronger with no drop outs or buffering.
However he does have Virgin fibre optic or whatever it is with speeds of 100+ so very different to our steam driven broadband. He does think it would do the same for us though albeit at a much lower speed etc.
It is this one:
ASUS RT-AX92U AX6100 Tri-Band Whole Home Mesh Wi-Fi System
Any thoughts form anyone?
