Re: Video speed at a crawl

For a week or two showing video on my Raspi 5 with NVME is impossible. The framerate is now something like 2-3 seconds per frame.
Before the axe fell it went smooth, Youtube video, TV, videos in news sites, no problem at all. The problem exists no matter if the connection is via wifi or ethernet.
Per now this raspi is mostly used for checking news, and there is no problem with that, except for embedded videos that run at 2-3 seconds per frame. Pages load at normal speed.
 I have tested up- and download speed with Speeedtest.net. The results are 50 to 52 Mb/s, and the connection is specified for 50/50 up and down.
 A Win11 PC standing next to the Raspi have no problem showing video. Win11 PC and Raspi are connected to the same wifi-net. This wifi is coming from an extender with wifi 2, 5 and 6. Connecting the Pi to the extenders ethernet port does not help the raspi's performance, but the Win11 PC shows videos fine using that ethernet port.
 I have some time ago experienced that having both ethernet and wifi active on the Raspi at the same time gives trouble, so I am careful not to run both at the same time.
 I have used some test from Tom's hardware, using vcgencmd, as shown at the bottom.
https://www.tomshardware.com/how-to/raspberry-pi-benchmark-vcgencmd
   Most test run on my raspi show similar values to the tests from Tom's. Difference comes at vcgencmd pmic_read_adc at 3V3_DAC_A current(17)=0.00000000A and current(18) where my raspi shows 0.0000000A, but Tom's show like 0.4 to 0.5.
 There has been several updates coming in to the Raspi lately. I check what is in the updates but often have no clue to what is does, and just let it install. But if an update causes havoc like this, other people would have been hit, and it probably would have been mentioned in this newsgroup.
 Hope it is something simple :-)
 Here is theoutput from my Raspi for the tests from Tom's:

A question: The router has the same SSID for 2.4 GHz and 5 GHz, but it is possible to click a setting "Split" and give them separate SSID's. Could that make a difference, except for making it more complicated?
Best regards
