Asus N66U - Merlin Firmware indication

[Bambalacul]

Hi,

On my router where I have installed Merlin last version of firmware 378.55 usual I have problem (with all version) when temperature rise and router start to be stuck. Now I eliminate upper cover and install one fan. When temperature go down under around 40 degree C on Network Map screen start to don't have any indication about internet connection, wireless availability , usb present etc. When stop fan again and temperature rise to ~45 degree I give refresh on Network Map screen and start to be visible all icons and informations.
I want to ask if this is any problem or I can ignore.

Thanks,
Dan
