I dont have a fix for u, but my router same model as yours crashes about once a day for me lately.
This has just started for me not to long ago and i have had my router replaced once, same issue.
i belive its some firmware glitch, but not sure i have a case going with tp-link.
Thanks for the reply!
This is strange, then it really must be a firmware bug/glitch... Would really appreciate some help from the tech savvy people on the forums. Someone surely knows something about this : \.
