Hi there, i have been having issues with wifi being poor and assumed it was my feed from Vodafone however when checking i am gettin 180+ MBS when in front of the router but can only get around 25 MBS from the tp links ? Is that about it ?. I have updated firmwear but mde no difference.I know the wiring can be an issue but i set the 3 units up on the same extension plug and still had the same results
