What Firmware version is currently loaded?
I'm using 1.05.
What region are you located?
United States
Are you wired or wireless connected to the router?
I've tested both. With my laptop hardwired to point B port 2 I get around 280Mbit. Wireless to point B about 10 feet away from it I get the same 280ish MBits. When I move 60ft down the hall into the other bedroom, I get 30MBit from point B on wireless.
What is the size of your home? Sq Ft?
What is the distance between the A point router and B point?
The house is about 3400 sq ft. Point A is on one end of the house, it's about a 100ft away from point B on the other side of the house, connected by cat6 Ethernet backhaul. With point B disconnected, I barely get any signal from point A when I'm in the bedroom. With point B connected, the wireless signal is strong and the wired speeds are high, so I know the basic connectivity is working fine, and my devices aren't trying to use point A instead of point B.
Have you turned off your mobile devices WiFi radio after leaving the bedroom then back on after arriving to the farther location?
It's up to the mobile device to connect to a signal source and will mostly keep connected to the farther signal unless such time as the signal becomes lost to the device or the device finally decides to change to a better signal or the radio is turned off then back on
That seems to defeat the purpose of having a mesh if you have to toggle your phone or laptop's WiFi as you move around the house. However, out of curiosity, I tried it, and it made no difference. Same speeds as before.
