Love the solid metal case, tiny size, and low power usage.  I used one to route my gigabit Ethernet for several months.  Compiled OpenWRT from source with LibreELEC&amp;#x27;s patches.  No hardware problems for me--I did apply that voltage patch for the MicroSD.  It handled the connection well, but couldn&amp;#x27;t quite push full gigabit PPPoE with VLAN.  Gets close if you enable acceleration, but then no AQM.  CenturyLink requires you to tunnel IPv6, so that on top of the PPPoE was a bit much for it, I could only IPv6 at about 300mbps.  No eMMC, you have to provide a MicroSD, but OpenWRT doesn&amp;#x27;t write to the flash at all in normal operation, so that was fine.&lt;p&gt;Now I have upgraded to the R5S.  This thing has HDMI out, dual 2.5Gbps + 1x Gigabit Ethernet, and eMMC.  It was a bit difficult to acquire, but I&amp;#x27;m very happy with it.  I can max out the Gigabit WAN now, with AQM which really helps.  IPv6 reaches over 750mbps, and the R5S has cycles to spare, so I think that&amp;#x27;s the full speed.  I can saturate the link over wireguard tunnels too.&lt;p&gt;The R4S is up on eBay now.</text></comment>

One person had a problem, dug into it, figured it out and got it fixed. The effects will ripple through time and space and improve the support of a lot of other devices now and in the future.&lt;p&gt;This is FOSS at its best. Thank you, @kohlschuetter.</text></comment>
