My Netgear C6300 wifi modem gives me only 75mbs when i use wifi and 300 when i use ethernet.

hi ve6cgx and thanks in advance.

im very bad in computers matters.

i have conected to my wifi modem my mac book

i dont know which band iam using, how can i get that info?

i didnt set up or change anything, just conected and called TWC and they activated my modem.

Should i change the wirelles configuration? i notice that i have a 5ghz wireless too, should i use that one?

thank you.
