I purchased this router at a great price on Black Friday. It replaces a Linksys EA6900, an AC1900 router, which I had upgraded to run Tomato USB.I have a two-story home and have devices on both floors. Internet is Charter Spectrum at 60Mbps. My Lenovo and Dell laptops have 802.11ac wireless cards but no MU-MIMO support. In addition to the laptops I'm running a TiVo, Surface Pro 2, and Roku 3 over wireless as well as a couple of wired devices. I have not enabled guest access nor did I use Linksys Smart Wi-Fi for setup. I don't have a need for remote access and so have not installed the app. The EA7300 supports static DHCP assignments as well as MAC address filtering, both of which I use.The router runs cool, unlike the EA6900.Overall the EA7300 seems to have better 2.4GHz range than the EA6900. It has been stable although there's really no way to tell from the UI how long it has been up between reboots. The 5GHz range seems about the same. I have noticed that the wireless throughput on 5GHz is markedly slower than with the EA6900. Opening a large file on a laptop over the network from my wired desktop (gigabit) takes much longer than with the EA6900 with the throughput showing about 9Mbps even when the connection speed shows 200Mbps. Not sure what is going on.I have a USB stick with about 3,300 MP3s connected to the USB port. Using DLNA I am about to find and play these files on the Roku. However, the initial scan for the files by the Roku Media Player is much slower than the same flash drive in the EA6900 w/ TomatoUSB.The graphical interface is just OK, a bit sluggish sometimes. The amount of performance data and configurability available from 3rd party firmware like TomatoUSB (e.g. WAN usage details, throughput to each device, uptime of device, etc.) makes that interface superior to what Linksys offers. Unfortunately, 3rd party firmware is not available for Qualcomm-based routers. On problem I was having was that the router rebooted a lot when I had static DNS value set. I removed those and it stays up now. It does use Google DNS if you don't specifyUpdate (1/11/17): My problems with downloading speed continue, and I'm deducting a star for that issue. My download speed is nominally 60Mbps after rebooting the router. After several hours (or overnight) the speed always drops to around 9MBps. The upload speed stays at 5Mbps. After rebooting the router, the download returns to 60Mbps. This holds for a couple of hours and then the problem reappears.I am on the latest firmware.Update (1/16/17): Amazon replaced the router (great customer service!) and the replacement exhibited the same speed issues. Linksys offered help. I started changing router options, including reverting to earlier firmware, none of which helped. I did notice that the Intel Ethernet adapter on my motherboard was throwing disconnect errors but it had been doing that since I updated to the latest Intel driver in September. That never seemed to bother the EA6900 but I decided to delete the driver and the Intel ProWin64 software and let Windows 10 reinstall just the driver. The driver that was installed was an older Microsoft driver and the problems seem to have disappeared! I'm getting full speed from my ISP as well as between computers.
