I experienced a problem with a brand new ISP supplied router just a month or two ago. Separating the 2.4 and 5gHz bands meant I could only connect reliably when my iPad was connected on the 2.4ghz connection. It’s not only very old router that cause issues. I now use an Araknis router and it works so far.
