Hi all 

for about 2 days i have a slow speed problem. Speed test of deco principal doesn't exceed 9mb (i have a 200mb fibra connection with tim) 

For 3 month i had no problems and speed connectivity was always good. I scan with deco lab from android app and he tells me that there is an high interference from other wifi network. I think to change channel to avoid this issue but i see that it's not possible 

what can i do about you ? 

sorry for my english, i'm italian and i tried to explain as best as possible :) 

thanks in advance 

Daniele
