sysupgrade will not nuke partitions, as long as the partitions in the image match those already on the disk. It's a somewhat high risk strategy, because few of us will actually track whether there have been partition changes. However, it does allow you to have the OS and persistent data on one SD card.
I am keeping regular backups and will just roll the dice, every time I upgrade.
havent tried. i'm still using an older anaelorlinski image.
untill they sort openwrt for stable i'm not really spending time trouble shooting rc builds as i dont have much free time lately.
edit : also given they just disabled ARM hardware encryption cos of arguments over the pi not supporting it. I'd rather have hw encryption than not. its NOT a god damn router and the fact you do not have hw licence in place for transcoding or encryption cos raspberry crew didn't pay for it makes it a VERY poor choice as a router as VPNs will be crippled on it. also its wifi is pitiful 1x1
If you are going to use openwrt you can either run it using a NVME SSD, Sata SSD, a good quality USB stick or a SD card.
The only thing to pay attention is that if you are going to use a NVME SSD, you will need to add a heatsink to the NVME and might need to add a 40mm 5v 4pin fan to the bottom of metal case, otherwise the NVME generates a lot of heat.
BTW that link that i provided is the best version out there right now, its the brand new V4 version with a brand new 2.5 Gbe ethernet controller the intel I226-V.
Also dont buy the combos which include ram and ssd, buy the bare bones unit(no ram and no ssd) and buy good quality ram and storage by yourself.
You can also buy it strait from the board manufacture ChangWang, since they also now have a store in aliexpress:
Thank you
I build my own PCs and have DDR4 and a few M2 drives.
I also have the heatsinks from those as motherboards come with their own. Shoot, I even have a 40mm Noctua setting around.
I think the new offering is what I've been waiting on.
I won't buy anything without 2.5 Gbe Ethernet ports any longer.
Yes, this new v4 version is using the brand new intel I226-V 2.5 Gbe which might not be supported by openwrt yet.
If that is a problem, then you can buy the v3 version instead which comes with the intel I225-V B3 2.5 Gbe ethernet controller which is already supported by openwrt as you can see below:
I'm building a dashboard for Grafana using Prometheus for the R4S but the nice features is that I have both the R4S as a router stats + the R7800 as AP wifi stats.
And I've also recreated the local dashboard to Grafana Cloud free account, so I can browse my home stats without using VPN but I use the local dashboard to save long term stats and receive the alerts (features not free for the Cloud Grafana)
I use this setup also to retrieve sme push alerts to the iPhone when xyz trigger is active, useful for know when the R4S is "working" for SQM or the temps rise a bit too much, an ayz Mac address join the WLAN, etc..
I'm writing an article with the details for the dashboard and setup, the R4S is a very nice device. I'm also trying a wifi 6ax AP attached to it with OpenWrt (the Netgear WAX202) but I'm not happy with the speed, near the AP I get 7/800mbps, but just few meters far and I have worse speed than the R7800 wifi 5ac. Maybe is too soon to use wifi ax on OpenWrt.
I'm only waiting for the Gigabit home connection. Now to me seems incredible to have 0 bufferbloat under load. And I don't have any issue but I think my device is one of the latest because it's different from the review I saw online, for example it doesn't have the hole on the rear (what's this? for a wall mount? but it's horrible ), and the "rubber/plastic feet" (but maybe he added them) and it doesn't suffer from the microSD power with safe reboot. I can reboot it via SSH without need to manually remove the power cable.
You have not posted screenshots of the ping from the R4s to internet, just to understand if it's a DNS issue or not, because opkg needs to resolve the addresses to avoid the failures you are getting.
Yes but I suspect you can browse internet because you have the right DNS on your clients and not on the R4S, from your config there's only WAN DNS, try to set the DNS also on the LAN interface:
Example, my config, use your/cloudflare DNS in your setup 1.1.1.1
config interface 'LAN'
option device 'br-LAN'
option proto 'static'
option netmask '255.255.255.0'
list dns '192.168.1.4'
option ipaddr '192.168.1.2'
PS: sometimes, in my case (during the first setup)by just using service network reload after I changed the network settings, didn't work correctly, I had to restart the device. I have no idea of why.
