Hi all.
I´ve come to a conclusion.
The problem with the constant restarting is one of my wired PCs.
I can have all of the wireless units connected, but when I start the PC in question, the 855 restarts 7-8 times.
I´ve been in contact with Dlink support, but they havent come further than asking me about my different wireless equipment, kinds of wireless-cards, drivers firmware etc. etc.
I still haven´t come to any solution, but now believe I´ve found the source of the problem.
I´ll be back when I know more. If any of you can be of assistance, please don´t hold back on your thoughts
