After being a loyal Asus router customer for many years, I thought I should try other brands to see if grass is greener on the other side.... so I got this D-link DIR-3040 plus two of their mesh units to extend wifioh boy, BIG MISTAKE, where do I begin, I've only had this D-link setup for 6 months, and have encountered the following issues:1. in router admin panel, connected device page is totally inaccurate, half of my devices don't even show up.2. I'm running two d-link "mesh" units with this router, after a router reboot, you often have to reboot each of the mesh units as well, what a PITA3. after a reboot, on most of my devices wifi will stop working until you do a "forget" and re-connect cycle4. wifi unstable, drops connection all the time, and just randomly stop working5. for some reason network shares randomly stop working, can not see the share even on same network. Didn't have this issue with my old Asus router.6. no firmware support, man I didn't know how good Asus's firmware support was until I started using this D-link, the firmware support is non-existent, D-link just don't fix things, even with this relatively new product. Asus pushed an update to my FIVE YEAR OLD Asus router.To D-link's credit, at least they didn't mess up wired connection, wired Ethernet connection is rock solid stable and fast. But nearly all of the WIFI related functions are a mess, nearly unusable.
