Hello,

My brother has big concrete house and he has been using the deco M5 for two years and it has been great in all aspects with great connection stability and speed but the coverage and range has degraded over time.

Now I'm planning to buy m9 plus for my big house and i feel it's more powerful than m5. However, I'm concerned about the connection stability with m9 as I've read in this forum some people having connectivity issues after the update. I care most about connection stability and one of the reasons for me to buy the deco series. Is the issue has been fixed with m9 plus and which deco do you recommend me to buy? M9 plus or the m5?

Thank you
