Hey guys,

I already have an external network (Fritzbox 6490) and an internal one (Archer C7). Now I want to build up a dedicated Smart Home Wifi.

The Xiaomi Router 3C I got was not the right thing to order for that. Later I read that the Router is not able to have OpenWrt or so on it and only supports 20 computing devices (64 in total, but 44 IoT-devices (Yeelights and so on do not count ...)).

Now I am looking for a cheap Router (<40€ in Germany) for a dedicated Smart Home network. The Router has to support like 40 wifi connections at the same time. I thought about 128 MB Ram (The 3C got 64 - seems not enough). Will that work if I just search a Router that supports OpenWrt with 128 MB Ram? Or are there any other limits (guess bandwith should not be a problem with the lights)?

Thank you in advance for your input.

Greetings
Andy

If you have a Xaiomi in your hands now, there are some people building firmware for it (not sure what the difference between 3C and 3g is).
for example https://forum.lede-project.org/t/xiaomi … g/5377/106

Devices which are connected but not moving much data do not require many resources of the router, perhaps a few kB each for their data structures.  The default in hostapd is 150 devices but that can be expanded.  In theory, a wifi AP can connect 2007 clients at once but no one actually does that.

Hey mk24,

thank you for your answer.

The 3G seems to have a different CPU and way more RAM and also supports 5 GHz, has a USB-Slot and Gigabit-Ethernet:

3G - MT7621A - 128MB Flash - 256MB DDR3 RAM
3C - MT7628N - 16MB Flash - 64MB DDR2 RAM

Guess that firmware will not work on the 3C. But thank you for your find

I guess I will just need to buy a new Router, but I do not know which one...

If you want to buy a new device, see https://lede-project.org/toh/views/toh_available_864

Thank you tmo26 for that link!

I will go it through and find a router with 128MB-256MB RAM. Should be enough for 40-50 devices at the same time I guess. Already saw the Xiaomi 3G on that list too - maybe I will just get that one (long time shipping ...).
