Sudden loss of wifi internet.
Sudden loss of wifi internet.
Had no problems for 2 years.
Then I tried to add an E4 to my 3 M5's.
Undated all the firmware at that stage.
Then everything went wrong............... wifi connected but very intermittent internet. Wired is fine, not over wifi.
Disconnected the e4 but the problem remains.
Do I factory reset?
Any suggestions?
