@Ivaylo Equipment port speed?? Do you mean if the setup from my Isp has 100 or 1000mbps right not the router right

I have a 40 Mbps connection. So is it ok to work on the current settings as you checked in the snapshot or do I need to change it.

@Ivaylo I have changed the settings as suggested. Can you please confirm till what extent can I try adjusting MTU size. I mean right now it's 1480 and what all variations can I do in MTU. Do find...

No i dont have the Tenda ones available sold it to some one already.

@Ivaylo I did checked with my Isp and they don't have a clue. Just had a question which is after changing the value and saving the changes reboot means I have to reboot the router is it??

First pic is when it connected again but at the same time was asking me to sign in. It drops for a few seconds and starts working again. Help with the fix please. For now it's happening oncw or twice...
