Recently, I've reseted my router after the reset my wifi became even slower around 0.3-0.5 mbps which is extremely slow
This is my router model :
DIR-850L

By reset you mean "Factory reset" - Correct.

If so, it is "Do -over" time.

Do the following links match your router?

Do you have the User Guide/Manual for your router? If not, download.

(Note: DIR-850L is listed as 'Discontinued". However, you should still be able to find the information. Be careful as there are some unscrupulous websites that try to take advantage of such things.....)

When you reset the router all of the configuration settings returned to their default values.

You will need the manual to start over and re-establish your network; wired and wireless. If you can remember the original configuration settings then you should not need to change any of the network adapter configurations.
