Also I would add; I had been onto Epson telephone support who completely failed to solve this issue. I had a suspicion that the printer might require a driver update as mesh's are quite new, but their only response was Epson printers don't support wireless exenders and they have o plans to issue driver updates to deal with it.
Not the best solution (to switch to 802.11b). This will have a negative effect on your overall wireless network.
Solution is for BT to *fix* the WholeHome system.
This is my undersaztnding of what has happened. I have not noiticed any adverse impact on the network speed in general. The Epson net config utility seems to simply instruct the printer what speed to communicate at.
Agree. I've used an wired ethernet connection. I'm not prepared to compromise my wireless network by using 802.11b.
Interesting article on why not to use 802.11b devices here https://www.howtogeek.com/210062/how-802.11b-devices-slow-down-your-wi-fi-network-and-what-you-can-d...
I completely agree that the BT Whole Home should be fixed to allow the Epson Wireless printers mentioned to work without changing their wifi settings.
Until then however, if ethernet is not possible, a "work around" is identified which I have been using for over 6 months. It has not caused any wifi performance issues in practice and we have lots of devices on a busy network
The printers are a few years old now. Have you checked that you have the most up to date software on the printers.
