An older i5 based Lenovo sff machine with a half height Intel Dual Band AC7260 adapter refuses to stay connected. Constantly have to let the troubleshooter "reset" the adapter. Sometimes only a reboot will restore the connection, which may or may not drop again within a minute. All software/drivers/bios updated to most recent available. Router is a TP-Link wifi 6 and signal is fair to good. Using a high mounted dual stick external antenna and a range booster is installed nearby. Is this adapter just not new enough to play nice with the 6 router?
