Can you please upgrage my Routers Firmware - TPLink AR1600v
Its currently running - 0.1.0.0.9.1 v5006.0 Build 180828 Rel. 56416n
The Route is running extremely slow....it takes 2-3 minute to log into it.
Your modem has the latest firmware.
Have you tried to use another browser? If not, try to use a different browser (FireFox, Chrome, Safari, etc.)
Have you tried using another device to access the modem interface? If not, try to use another device for comparison.
Are you using a WiFi or a Wired connection? If WiFi, try to connect via Wired then turn off the WiFi of your computer, then access the router interface if there's any difference.
Let us know how it goes.
