870 a step backward from 850

Ya, you won't see anything faster as your USB adapter is limited by its USB 2.0 support:

You need a adapter that supports USB3.0 to take advantage of what Wifi6/6E or 7 offer. 

Not a good comparison or result for what your using. My 870 out performs my 850 series though the 850 series is solid for his features. All my BE adapters are USB 3.0 or PCIe supporting.

I just "upgraded" from a 2 satellite 850 system to 1 satellite 870 system.

I moved from a house to a condo with smaller square footage and did not need the coverage area.

The new system will not support in the same locations the router and 1 satellite.  I have to use a hardwire link.

The speeds are almost exactly the same even if I use a wifi 7 dongle in the computer (ASUS BE92).

 

The units are larger.  The biggest improvement is putting the sticker with the default SSID and password on the front of the unit rather than the base.

 

I see none of the benefits except for the ability to select 5ghz channels to move away from neighbors.

 

Unless you need the wifi 7, it is not worth the money, as the 850 2 satellite system is about 40% of the 870 system.

 

Really a disappointment.
