Hi, all.
I have TP Link Archer C7 v2 (16MB flash, 128MB RAM, Atheros-based, MIPS CPU architecture), dd-wrt build r45454 (1/15/2021). GUI has no SNMP support, so I attached USB flash drive (512MB Optware ext2, 64MB linux-swap, 14GB Data FAT32 to share with Windows devices via FTP), installed Entware, then added SNMPD. No errors during installation.
It works, but the bandwidth output is weird - about 3 times over than the real values. I tried with different interfaces, but they all report the same, roughly 3 times higher bandwidth (I got 20Mbps up/down, and when do speed test, the graph reaches almost 60Mbps). Also, the graph looks "choppy", like it shows activity, then stays at zero for 1-2 seconds, then shows spike again. Tried different apps (even mobile), but they all have the same readings. Is this a bug?

kernel-panic69,
The SNMP is Entware package, the router firmware itself do not have SNMP built-in. I just think the hardware of this Archer C7 v2 is really cheap, and will never work better for this specific purpose. I also can't have FW logging on high, because it would run 100% CPU non-stop. Even with this logging set on medium, I still see a delay in the Wall Watcher entries...
At this point I have accepted the fact that it's as good as it gets with this router.
Thank you for your input. I am "glad" it's not only me having such issue. I can't go back to such old build(s), as I need some of the features that recent builds have...
