[WRT1900AC] "Linksyssmartwifi"/default firmware is... really bad.

Question

I've bought two WRT1900AC's, one for my home, one for my company's small office. After using them for a few months, I've run into a few problems which are basically going to force me to swap both of them to third party firmware (once it's stable enough to do so), at least until I replace them with Netgear/Asus routers. I am not inexperienced in this sort of thing, but I can't even tell if the options to fix some of these issues exist somewhere in the pages, or if they're simply nonexistent due to what looks like random reorganization and dumbing down of features.  1. When I try to log into my office router from my office via "linksyssmartwifi.com", it presents me with the email/password login, and logs me into my home router. There is no link to log into the local router on the page. I would much rather be able to go to 192.168.1.1 by default--you're not making anyone's lives easier with this "linksyssmartwifi", largely because existing tutorials usually direct readers to 192.168.1.1.  I had to interrupt someone working so I could log in to change the guest password, which leads me to the fact that... 2. I can't remove the guest network password. I have 100 megabits downstream in each of my locations, so let me deal with any pirates or bandwidth thieves; I'm fine when I see my neighbors' guests connect to my WiFi with their iPhones.  3. The "simplified" device view is often incorrect in matching the names of devices/IPs/manufacturers. Give me a proper table with all of this information, including DHCP lease times, preferably not in an oval-shaped format.  4. I'm limited to three devices for QoS prioritization. I have dozens of devices, including at least 4 Rokus. 5. I'm pretty sure there was no use of HTTPS when I initially registered my router account.  The router is probably fine for most people. The packaging was neat, the hardware feels solid, and the idea behind working with OpenWRT is great, but the existing firmware is irritating to use every time I need to use it. If 1 and 2 can be fixed by the time I change routers, I'll consider recommending Belkin products to my family again, but not until then.

Here are my takes on the challenges you are experiencing with the router. I hope you will find these answers helpful:
1. When you access your office router's configuration page, do not use the username and password you assigned to you home network. Be sure to use the right login credentials when accessing the router's page.
2. We cannot disable the security settings of the guest network but we can disable the router's Guest Access instead.
3. A firmware upgrade may help refresh and update the Device List.
4. You can connect all the other devices to the network. Adjust the router's wireless channel to improve the wireless connection.
5. If you want to set the router to use https, you can enable it on the router's configuration page under Connectivity -> Administration.
