@Alexandre. First of all thank you for all your help! so did what you said and the main deco is fine however the other decos are doing about 120 to 150 max. so there might be interference with them....

@ImtiazAli main deco then satellite. seems the main one has increased the satellite is still slow

@Alexandre. I'm not sure what you mean as I'm having a moment. the router has a ethernet cable to the deco then tirelessly to the others. I tested it on a app on the deco WiFi that's when it was 200

@Alexandre. so I changed the cable and its upto about 200 now. I did change the m4 for another m4 and I'm not sure if that has made any difference. its much better but not sure if I can get it any...

@Alexandre.

@Alexandre. thank you but I can't find how to change it on the settings that link is completely different to the app on my phone. do I need to log in from a laptop?
