What matters is not the brand name but compatibility of protocols. There is no point in, say, investing in an 802.11n router and using it with clients whose wireless adapters only support 802.11g. You only state the speed of the router and not its protocol standard, so it could be a "pre-N" or "draft-N" version of 802.11n.
Don't use a wifi adapter unless it provides an obvious advantage -- Ethernet wins every time if there is no practical gain, such as a positional issue.
And please close your other thread -- duplicate postings are discouraged, for obvious reasons.
