Fixed up my post..
Edit:
- Server (ethernet connect) thruput of 900Mb/s only 60Mb/s on Beta4.
- Laptop: (wireless connect) the thruput is about 70-80% of normal on Beta4, then Beta3 in same physical location (my desk).
- SpdMerlin. Beta3 & Beta4 (loads 3/4/5) thruput the same. Beta4 1st & 2nd loads, thruput was less then a 1/10 of usual.
Summary: Beta3 ok on all units for thruput. Cannot find a solution for Beta4, after power off/ons reloads, server & laptop re-boots etc. Saying with Beta3.
UPDATE
I also had thruput performance issues with Beta4 on my RT-AX88U. Download went from 900Mb/S to 60Mb/s after a dirty conversion from Beta3 to Beta4. Checked GUI settings in QoS, disabled AI Protection and no resolution. BTW - with Beta3 install, had done a full factory reset and re-install of everything, after installing Beta3.
Actions to date to find a fix...
- Reinstalled Beta4 on Beta4 and no change.
- Reinstalled Beta4 again on Beta4 with USB mounted (opposed to unmounted which I usually do) and no change. Grasping at ideas now...
- SpdMerlin (Add-On Tab) was also showing the big drop of download speed on Beta4.
- Dirty conversion from Beta4 to Beta3. SpdMerlin, my laptop & server all back to previous performance download performance. yippee!!
- Reinstalled Beta4 in another dirty conversion over Beta3. Now Spdmerlin & my laptop ok, but not the server (60Mb/s). Did ethernet ipconfig resets on server, no changes.
Still playing to find what will resolve getting the server back working at 900Mb/s download on Beta4, opposed to current 60Mb/s.
