Router/Version: WRT1900ACSv1 / DD-WRT v3.0-r47656 std (11/18/21)
File/Kernel: CLI webflash / Linux 4.9.290 #2921 SMP Thu Nov 18 01:52:11 +07 2021 armv7l
Previous/Reset: r47608 / No
Mode/Status: Gateway, OpenVPN Client, FreeRADIUS Server, VLANs, VAPs, WPA3 / Uptime 50 minutes
Issues/Errors: The first 20 minutes looked brilliant, but then serious random slowdowns began around minute 23 and I'm not sure why (e.g., down to 1% or less download speed about half of the time, and down to 1% or less upload speed about one quarter of the time). I played with various settings, mostly dns so far, but nothing conclusive yet. Log attached.

EDIT: After 19 hours up and a bit more testing, the intermittent 1% throughput issue didn't seem to be DNS, Wireless, CPU usage or anything else obvious. It might still be OpenVPN, perhaps even my provider (despite indistinguishable results through various of their servers). I've now got about 33% of normal throughput (seemingly random, but possibly related to switching from tcp to udp), which is good enough for me to wait it out to see if anything else improves over the weekend. I haven't been able to test OpenVPN Client definitively because disabling it in the GUI seems to leave me with no usable connection (and I'm not ready to reboot the router just yet). I tried WAN release/renew to no avail, but reenabling the OpenVPN Client does get the sluggish connection back. I must be overlooking something...
