How to maximize speeds with a Broadcom AC card and R7000?

Hello all, I've upgraded my motherboard to a Asus Maximus VII Impact with an onboard Broadcom 802.11AC Network Adapter. I believe it is model BCM43XAC_NT61 based on the device ID. On my 5GHz ban...

    I changed all the settings. Immediately made the signal jump to four bars, and then drop down slowly to 1 or 2. Not much difference in download speed.

    But, I got a new modem from Optimum, one with Docsis 3.0, the Arris TG862G, and it allowed my dl speeds to go up to around 7.0 MB/s. Much better.

    Should I look into getting one of the high end Surfboard modems to further increase speeds?

    And is there anything else you guys can think of regarding the Broadcom card or the router to further increase DL speeds?

    This is the antenna that came with my motherboard. Would I be better served with some standard antenna?

    Will putting aftermarket antennae like this do anything or is it just gimmicky? How come they don't list it as 802.11ac compliant in the listing?

    Thanks again

    Cheers

It sounds like a windows laptop. Windows does not report the wireless card as .ac, for some reason, but based on your speed it is correct. Here's a list of setting for your card (or similar). Ensure the bottom two are set..

802.11n channel width for band 2.4: Auto (not in 20 MHz only)
802.11n channel width for band 5.2: Auto (not in 20 MHz only)
802.11n mode: Enabled
Fat channel intolerant: Disabled
Preferred band: No preference, or Prefer 5.2Ghz band
Roaming aggressiveness: Medium (or less)
Throughput enhancement: Disabled
Transmit power: Highest
Wireless mode: 802.11a/b/g
HT mode: VHT mode

Also, ensure QoS is DISABLED on the R7000.
