I’m experiencing a problem with my Deco XE75 PRO after the latest firmware update. I've had the update for six months, and everything was fine at first. Now, I'm experiencing extremely slow video play

No FW update for XE75 for >6 months

HW version is listed as HW version US/2.6. The Deco app gets frequent updates but not the FW. Is this router no longer supported? Should I replace it? I bought it thru Amazon in 2024 as TP-Link Deco X
