Hello,

Last October, I bought a package of 3 TP-Link mesh router Deco 20 AX1800.  

After installing them, I made thorough verifications and tests.  Our home was entirely covered: 3 floors and outside as far as 30 feet from the house with speeds varying from 45 to 65 Mb/s depending of the location of tests.  Our ISP speed is ±60 Mb/s.  

Once in a while, I checked the network and speed was not an issue.  We lived mostly happy ever after ... until recently.  

Speed has been slowing.  At first I thought it was because we changed the wifi network's name.  I made new tests, and it appears that after restarting all routers, I get high speed of ±50 to 60Mb/s but soon after the speed drops to ±8Mb/s).  

Ever heard of a similar problem ?  What is going on ?

Thanks in advance.
