So I recently purchased the TP-Link BE550/9300 router from the deal I posted not long ago. Out of the box everything connected without issues and worked as they should, however after the firmware update for whatever reason it killed the connection of this wireless garage door control unit I have that was connected to the router via ethernet cable. I contacted TP-Link phone support and the lady on the phone noted down my issue and said she'll pass the info on to their technician/engineers. I got an email response within a day and within the week they had already developed and sent me a beta firmware that actually fixed the connection problem and during that time they kept me updated throughout.
It was obviously a very niche issue so I was pleasantly surprised they took it seriously instead of just palming it off like it's not their problem and actually got it fixed for me.
Thought I'd share what was actually a very positive support experience for once.
The first batch of items I bought for my home server rack was a Synology NAS, few suvillence cameras and a TP-link POE switch.
Over the past decade I have gone through many different TP-link products, there were products dead on arrival (DOA), there were faults happened within or outside warranty period.
But overall my experience with them is A++, I don't like to stick to brands so I can try out different things, but with few unfortunate expereinces with other brands with similar origin, all my important POE switches are now solely from TP-link
