Hi

Just got the  Archer GE800 to update my Archer C5200
 

I have the following issues

1-    In some rooms ( around 6 meters away ) I get not less than 75% of the signal , but the speed is very slow, my connection is speed is 1gb , but what I get 3-5mb, i tried the smart connect , 6ghz, 5ghz,      2.4ghz, and the MLO , all the same.

     my older AC5200 game me much better speed

2-   The 6Ghz sometimes disappear, or won't connect.

3-    MLO is slower than 2.4/5Ghz ( Smart connect )

problem 2 & 3  , maybe will be solved with firmware update, or is it something wrong with the router?

But number 1 , is the main problem for me, why do i have good signal but really poor speed?

I even tried an extender ( RE650 ) just to see the result , the 2.4ghz in the extender connected to the router with no issue, but the 5ghz did not.
i tried both smart connect or separate the 2.4 and 5ghz in the router, still the extender could not connect to the 5ghz. whenever I scan for available network , the router 5Ghz never shows up.

So , is there any special setting I need to do  , wait for an update , return the router, or go for other brand?
