I've just had my internet speed upped from 100 Mbit to 200 Mbit, and I'm having some issues, as my decos seem to be running at 100Mbit still only.
My network plan goes:
Provider hub > Main Deco > Switch > connected devices (every device in the house is either connected to deco wi-fi or through the switch, provider w-fi is switched off)
Other decos (4 in total) no Ethernet backhaul but devices are connected to the Ethernet hubs on the satellite decos.
All cables are Cat5e or Cat 6.
I have connected my pc via Ethernet directly to the provider Ethernet and got the full 200Mbit so I know I'm getting full speed from there.
I've run the 'Test Internet Speed' function on the android app and that also shows that the main dec is getting 200Mbit from the provider hub.
If I test my PC when it's connected to the Switch (TP-Link TL-SG1005D, 5 Port Gigabit Ethernet Network Switch) and run a speedcheck there it's only showing 100Mbit, but if I connect my PC directly to the main deco Ethernet port it's still only showing 100Mbit
On my satellite hub Ethernet port connected PC this is also only getting 100Mbit and that's Wi-Fi mesh connected only, it's not going through the switch.
I'm also only getting less than 100Mbit on my phone WiFi (Huawei P30 Pro) even when I'm only inches from the router.
1. Main Deco > switch (connected devices only get 100Mbit.
2. Satellite Decos Wifi/Phone Wi-Fi is not reaching higher than 100Mbit
Signal going to the Deco is correct
signal leaving the Deco (wired or wi-fi) is losing half of the speed (200 > 100Mbit)
