RT-AC5300 not getting gigabit speed on ethernet

    Hey there guys, so I recently upgraded to gigabit internet. The Ac5300 router I have had for a while now and followed some online guides to get it set up to get some decent speeds on wifi. I am getting about 450-530 Mbps on wifi on my phone and only 110 Mbps wireless on my laptop. So I tried hooking up the laptop via ethernet and still only get 560 Mbps. I am unsure if it has something to do with the settings I changed in the router or the settings in the network cards on my laptop. My laptop is a Dell Inspiron 7559 and the phone I am using for the speed tests is a Samsung Galaxy Note 10 plus. I would like to get the highest speed possible on both wired and wireless but mainly wireless. the settings I changed on the router were based on a network where there is sometimes a lot of devices connected at once. Please let me know if I am missing important information to diagnose my issue. Also, the router is on stock firmware and up to date. Thank you!

    The laptop has an Intel Dual Band Wireless-AC 3165 card and the advanced settings are as follows:
    802.11a/b/g Wireless mode= Dual-band 802.11a/b/g
    802.11n/ac wireless mode= 802.11ac

    Advanced EEE= Enabled
    ARP offload= Enabled
    Auto Disable Gigabit= Disabled
    Energy Efficient Ethernet= Enabled

    Here are screenshots of the settings on my router:

    Swap out the old wifi card in your laptop for the 7260. The 3165 has some major issues. It was made when mfg’s thought that it would help with battery life but in turn killed modern day users speeds.

    Does this give you accurate results? I've always found that an on-router speed test gives unrepresentative results because the router cannot use hardware acceleration. For example, my LAN client can get ~360Mbps whereas the same command issued from the router only gives ~100Mbps. I would imagine the discrepancy would be even larger at gigabit speeds.

    You said you upgraded to "gigabit internet". Does that mean that they're actually supplying you with 1Gbps or is the 560Mbps you're seeing more realistic?

    Can you plug your computer directly into the ISP's internet feed (i.e. without an intervening router) and test the "raw speed" that way?
