Re: Linksys WRT1200AC v2 / WRT1900ACS v2 support
Thanks for the response. I tried flashing the image from Kaloz you linked in your first post (openwrt-mvebu-armada-385-linksys-caiman-squashfs-factory.img) and it seemed to soft-brick the router. Fortunately I was able to recover by toggling the power switch 4 time, waiting for the lights to come on each time. I ended up reflashing the CC image and updating the mwlwifi driver per the OpenWRT wiki, and (fingers crossed), everything seems to be ok for now. Should the issue recur, I will delve further into it. As the old addage goes "If it ain't broke, don't fix it."
The link in your last post isn't working
I'd highly recommend @david502's builds. They have the latest wifi driver, are based on LEDE (which branched from Open-WRT about 6 months ago and has had alot more progress made -- it looks and works just like Open-WRT). There's a link in the wiki, but here it is for you (link taken out). It includes most if not all of the packages you'll need (fully featured) and regularly updated (once a week).
I'd recommend flashing back to the stock Linksys firmware, then flashing @david's build.
Some info on LEDE can be found at (link taken out), but if you didn't know, you'd think a LEDE build was Open-WRT. Most, if not all, the devs who make firmware for the WRT series now base it on LEDE.
Edit: And for the fastest speeds and best reliability, you should always and only use WPA2 PSK with CCMP (AES)
Starcms, thank you for the suggestion. The issue unfortunately is coming back again, so I need to do something, and I dont know if my skills are quite up to Sera's suggestion of building my own branch.
