Hi,
It was given else where in the thread in this forum, i found that saving and exiting is the best way to stop some cross bugs in browsing the router page by some expert. I could not recollect the thread.
If i do not want to save anything, that i entered in-advertantly, fearing that i may loose internet connection, i usually exit without saving but closing the router page.
how to properly exit the page.
The best place to get your answer is from the routers manufacturers support site.
