Past three nights my internet has died at 11:07 pm on the dot; rebooting the TP-Link Archer A7 brings it back. Only recent change is a cheap outlet timer I plugged in by the router — anyone else?
And i had a mechanical timer do exactly this — when it flipped, the inrush dipped voltage and my Archer A7 soft‑rebooted; putting the router/modem on a small UPS solved it. @OP can you stick the A7 on a UPS or at least a different outlet just for tonight and see if 11:07 vanishes?
