Hi support, 

I recently purchased a 3-pack Deco XE75 Pro but it is not meeting the promises that TP Link makes!

Previously I had an Archer AX3000, and this was my setup:

- I have 2 Gbps fiber connection from my ISP (tested with wired directly through their Modem)

- With my ISP support, we configured their Modem to act as a bridge. 

- Connected the 2.5 Gbps WAN Port of the bridge with the 1 Gbps WAN Port of the Archer.

With this setup I used to get 900-920 Mbps through wire (through the 1 Gbps LAN Port of the Archer) and anywhere between 700-800 Mbps on WiFi 5Ghz.

Recently, I replaced the Archer with Deco XE75 Pro (3-Pack) and did the same setup as above (except that the the Deco has 2.5 Gbps WAN Port, not just 1 Gbps).

So I assumed that now with the 2.5 Gbps link between the bridge and router and by using WiFi 6E, I should at least get anywhere between 10%-20% improvement, however that was not the case!

Now using the wired connection I get at max 850 (not 900 as I used to) and over WiFi I get max. 750 (not 800 as I used to)! What's up with that!?

I got a notification to update the Deco firmware, which i did. Then I reset everything and tried the setup all over again, double checking every step. Still same results!

Please advice, thanks
