Connection issues (disconnects) with ASUS Router

[cordvision]

My milight hub keeps becoming unresponsive anywhere within 2-24h. I have to unplug/replug the milight hub or re-start my ASUS router to keep it going again.

Over the last few years, I found a lot of people that appear to have the same or a similar issue. I even built a second unit just to make sure there is no hardware problem.
I finally found out what causes the issue: If I disable "IGMP Snooping" on the ASUS router, the milight hub no-longer disconnects and works exactly as expected. What I can gather from my online-research, it looks like this is an issue related to ASUS routers and ESP8266 boards. I'm not sure if this can be fixed in the milight hub firmware, but I thought it would be at least valuable to post here in case other people have the same issue (If I knew about it, it would have saved me a lot of hours).
Having IGMP Snooping permanently disabled is not a real solution... so I guess if there is no fix, I will have to get rid of my ASUS router.
Any chance somebody could give some insight if there might be a firmware fix?

Firmware version
