I just bought the RE7000 Linksys extender and the Linksys EA8100 router. I'm not getting the advertised speeds on my Samsung S21 Ultra phone and when I connect to the extender it drops speed. I refuse to call Linksys tech because the last 4 times I contacted them they have foreign people and I can't understand a damn thing they are saying. One told me that the speed of the router would override the extender. The router is 2.6 Gbps and the extender is 1.9. The highest I get on the 2.4 is 86-175 through the extender, I get 156-175 on the 2.4 without the extender. On the 5 I get 866 Mbps through the router and get this it shows 756 then drops to 260 Mbps. Something isn't right and I spent 5-6 hours trying to figure it out. The reason I got the extender was that we plan on getting security cameras and need the wi fi to reach the garage. At this rate, it's not going to happen. Any help would be appreciated.
