Opening Ports tp allow my Humax box to connect to my router

[#1]

Thanks very much.  I hope this reply gets to all who have contributed, and would you sort that if it will not?  I am doing as you suggest.  Yes the access points are expensive but the house is stone with thick walls, and nothing seems to have worked reliably and I'm always getting signal drop-offs.  My wife is not a happy bunny when she does her Zoom Pilates!  Obviously it's all my fault!   So.......... I'm installing 3 units, plus a few bits and pieces my 26 year old geeky (sorry) grandson has suggested.  He assures me this WILL fix my problems.  Fingers crossed!

Thanks again for everyone's interest.  What a helpful forum this is!  VBW J

We use powerline adaptors to connect Humax box and also to distribute WiFi around the house ( TP-Link TL-WPA7510 ) and never a problem,  they are more reliable than the Plusnet router LOL...

They are dual band 2.4 / 5 GHz wifi and the router wifi SSID is cloned to any wifi extender..
