Why you use the factory image ?
Just use the sysupgrade -> openwrt-18.06.1-mvebu-cortexa9-linksys-wrt1900acs-squashfs-sysupgrade.bin
Thank you that's a very good point 
Works now 
The squashfs-factory.img, as I understood it, is only, if you buy a new router, that still has its factory firmware (mostly crappy lol), its the one you use for flashing, wiping the factory Firmware to OpenWRT ..if you have openWRT already installed, the sysupgrade.bin is the right one to go for =D

Weird LuCI performance hit: When I tried to upload some big distro images to my samba server/USB hdd on my WR1043ND_V1 I noticed a very bad WiFi throughput (jumping between 0 and 1MB/sec in gkrellm). I used Firefox to have a look on the status overview and as I connected to LuCI the throughput went up to steady 5.7-5.9 MB/sec (150 Mbps WiFi in my laptop). Then I closed the Firefox tab and WiFi speed was slowed down again. If you don´t logout before closing the Firefox tab LuCI will wait for hours for the connection to be closed and will slow down. I hope this isn´ t made intentionally for lazy people that should learn to use the logout button.
This is not really an issue with 18.06.1 (although it won't exactly get better with newer software versions).
The TL-WR1043NDv1 has a 400 MHz MIPS 24K SOC (AR9132) and 32 MB RAM, USB (especially USB <3.0) is a quite compute intensive protocol, so is serving wlan cards (interrupts), routing/ NAT/ firewalling at >50 MBit/s or even just refreshing the luci overview page. Whenever you push one of those parameters, the others suffer (single-core CPU), this is particular obvious on devices are are already pretty marginal to begin with.
I understand that this router is the bare minimum hardware supported but why is there still a connection to LuCI hours after the browser tab has been closed. Connecting to LuCI cured the problem even before logging out when the overview page was active. Neither side (browser or LuCI) seems to want to drop the connection even after hours. This polling for a non existent browser tab was ten times worse than a nicely refreshing overview page. This is a thing maybe even more powerful shouldn´t waste cpu cycles on. Powerful hardware might mask it or run a little hot(ter).
@Schugy I don't observe the behavior you are describing.
If you run top in a ssh session, what measurements do you get for CPU% and Load Average before you start Luci, while you run Luci ( say for 5 minutes ) and after you close Luci and wait 5 minutes.
How are you detecting connections are not closing?
Hello mbo2o, thank you for your reply. Luckily I kept the xterm window open and can present you some numbers. The dmesg output is clean. When I added swap the dmesg output was prolonged a single line without errors in between. This unclosed connection theory is only a guess because I used LuCI hours earlier, then closed the browser tab without ever closing the whole browser and the performance hit went away when I logged into LuCI again. Usually I´d guess cpu usage goes up when a LuCI page is actively in use and not running mad in the background.

@Schugy That looks like Samba smbd ( NAS Drive ) working away real hard.
So most likely samba is using up quite a bit of CPU to to write to your disk drive and WLAN is doing the same. It has nothing to do with Luci. Your just pushing your router to its limit.
The firewall fw3 is also has high load but I don't enough about that.
TP-Link WDR4300 updated without problems here.
Upgraded 18.06.1 on TP-Link AC2600 without problem.
Upgraded 18.06.1 on Huawei HG556a with Wifi lost because of cal_data partition corruption, and rollback to 17.01.5.
And Xiaomi Mini upgraded 18.06.1 without problem, too.
Hey,
First off: Thank you all for the new releases!
I'm still running Chaos Calmer on my Linksys WRT1200AC but I finally have the time to upgrade. One question though: The wiki page for the WRT AC series still states LEDE 17.01.5 as the latest stable and OpenWRT 18.06 RC2 as testing. Is the wiki page simply outdated, or is there some reason why I shouldn't flash OpenWRT 18.06.2?

Thanks, 18.06.1 it is. 
Hi,
I'm currently using LEDE 17.01 release on a TP-Link TL-MR3020 and wish to update to this 18.06.1 version. Unfortunately there is no image for this router in download area.
Have you dropped support for this device in this version or is it just a temporal failure? I cannot see that fact in Changelog.

Your device doesn't have enough flash to fit the full release build anymore, while it is still attempted to be built, it fails. You will have to use imagebuilder to strip down the installed packages or use a snapshot image (which don't include the webinterface, luci, by default and are therefore slightly smaller):
Thanks for the answer, I'll try the imagebuilder
@pkreuzt - I have been meaning to upgrade my MR3020 to OpenWRT 18.06.1 from LEDE 17.01.4 as well (just haven't had the time). RAM could still be an issue, but the primary problem is the 4MB flash.
With that said, my recommendation would be to only perform the upgrade if you either plan to use extroot or if a non-LuCI + very bare-bones installation is sufficient for your needs.
Assuming you're going to utilize extroot, you may want to include the packages for the extroot process to make the process a bit easier. There are a few threads about this, such as this one, where there are some recipies suggested (mine is in post #12 of that thread, my last attempt was successful on 17.01.4, haven't tried with 18.06.x).
good luck!
