X55 Pro (3-pack) crazy speed drop after update.
Everything worked great for 2 days after purchase. Got solid 900mbps wired and wireless speed (backhaul) from every pod. Until today. Update was installed and now speed dropped to 80mbps wired/wireless. Spent whole day with tech support, no solution. What's interesting is that main deco still has 900 wifi speed, but when wired only 80. 2nd and 3rd deco 80 mbps. Tried everything including switching main deco, hard reset all 3, nothing works.
I was trying to downgrade firmware,but it doesn't let me because latest firmware installed. Is there a chance to downgrade? Everything worked great before update.
