				Hello, 
 
 I saw in shop that there are external antenas that can be bought separatly (not dlink). Will those work with dlink and "give" a boost to the router if i buy them? I saw some 7 or even 9db antennas (2 - 3 times as big as orginal dlinks). Will it work or i shouldn't even bother?
 
 With regards,

				You need dualband antennas for the 855.
 Most separately sold antennas are 2,4GHz only and you can't use them with this router.

				Well that wasn't the question. There are dual band antenas out there. So the question is if i will buy such antenna and replace those connected will those work, will those work better on short, long ranges) or it won't change anything.
