I switched out my Synology to Truenas, it works way better then before. I am much more happy with the current setup with Truenas
I found recently a different firmware for my Asus router and it works way better then the official one. It is called Asuswrt-Merlin and I personally can recommend it, if it works on your router too. You can make a test and report back if you like it too.

I had bandwidth problems with both lan and wifi before and now I can fully utilize it.
Merlin does the original firmware for Asus routers, then Asus just borrows it and fills it with bloatware.
I just keep the Asus OEM firmware because it has autoupdate and dosen’t requires me to keep track of any new updates. And I believe that support will be always there from Asus, it’s a company, but Merlin is just one guy, that gets old and someday will stop developing.
But yes, Merlin firmware for Asus routers is the best.
I firmly believe that networking, and especially anything that has to do with radio, shall be delegated to companies that make it their top priority (and whose livelihood depends on not fucking it up); not those who treat routers as a consumer gimmick (Asus) or “business” gimmick (synology also makes overpriced junk network equipment).
Next, I would consider Asus auto updates a negative. The risk of new security holes being found in foundational software like iptables is miniscule, but risk of Asus fucking up next software update is 99%.
More importantly, if you use wireless as part of your gateway — then you shall not accept anything but enterprise hardware. There is no shortage of way to mess up wifi in a subtle and not so much ways. Consumer electronics companies grab whatever current prerelease chipset firmware was current at the device conception stage at worst, or whatever vendor sends them at best, and ship to you. You don’t want to run that mystery meat.
If you still not convinced: consider, do you really want to have to do anything with the company that allows what led to CVE‑2025‑3464 to happen, on purpose, for no good reason other than sheer ignorance.
