Thats the joys of IT you get the info that the OP knows, and you have to work out the rest, or ask further direct questions to fill in the blanks. You need to understand what is meant by "54mb and above" - what else would it relate to other than WiFi speeds? I can't think of anything, thus it seems reasonable to assume that it refers to 802.11g as a min requirement, there doesn't seem to be enough doubt to request further info from the OP IMO.
"wired network connection for NAS" is very unlikely to be referring to a token ring ethernet since they are so rarely used these days that I've never seen a router incorporating connections of this type (ie - coaxial networking) - so it stands to reason that the only likely requirement inferred is for a 10/100 ethernet connection. (Possibility of GB networking being a requirement I suppose, or even fibre networking, however these are more specialised - thus if they were what was required, the OP would have probably had advanced knowledge, and would have known to include them specifically in the SoR.)
As you say, its a bit of guesswork to come up with those answers, but there isn't a logical alternative for either, and certainly not another one that is more likely, thus stating that the suggested solution is not compatible with the SoR is disingenuous to say the least. (Again - IMO)
Perhaps it would have been better to ask for further clarity in the SoR if you felt confused about what was really required, rather than telling people that the suggested solution was not compatible with the SoR.
