Poor performance from Deco x68
I have my Deco x68 plugged into my modem with a cat5 cable. If I connect to my modem's wifi directly and run speedtest.net I get 334Mbps. If I connect to the Deco wifi I get 92Mbps speed. Both tests are run with a laptop less than one meter away from the modem and the Deco. Why is the Deco so much slower?
I don't have much experience with setting up a mesh, so all suggestions welcome.
Thanks.

Hi, have you tried replacing a new Ethernet cable to connect the ISP modem router to Deco X68?
-It is also suggested to connect the ISP modem to another Ethernet port of the main Deco X68.
It seems like the internet connection speed between the ISP modem and the main Deco X68 is capped at 100m/s.
Please also check the QOS settings on the Deco App to make sure it is disabled or set to 1000mbps download/upload.
By the way, may I know how long you have had Deco?
Wait for your reply.
Best regards.

@David-TP Thanks for the reply.
I tried a new cable and different port. Same result.
My ISP has now sorted out my internet connection and I am now getting over 740Mbps, it's even spiked to 790 a couple of times. But the speeds I'm getting from the X68 hasn't changed much. It tends to be around 95Mbps most of the time, but it has reached 130Mbps on occasion, so I don't think it can be capped at 100Mbps.
Tried changing the QOS to 750 and 50. It didn't seem to make any difference. It was disabled before I changed it.
Iv'e had the Decos for a while now, over a year I guess. I have four Deco E4 units around the house and the X68 in the garage next to the modem. Geographically, the garage is under the house, and there is an E4 almost directly above X86. The rest of the E4s are on the same level with some walls in between but not very far apart. Twelve meters max.
