Upgraded to tplink A6 V3 latest version from old netgear router in hope of getting better wifi experience and speed. But internet stops working (WAN port light shows red light) after few hours of working. Reboot resolves the problem, but it recurs every few hours. Got everything checked from ISP PPPoE, everything is fine from ISP as old router works good. Went through google search, found some articles on community and you tube that almost everyone who got this new version of A6 facing this issue. Firmware is also updated on first connection to latest. As suggested in you tube/community articles, updated the MAC address of new router with ISP even though it seems irrelevant with PPPoE, did it to rule out if that is the issue. Noticed that with Smart Connect setting OFF, it works for longer time and then gives issue. But with Smart Connect ON for 2.4 GHz and 5 GHz to share same SSID problem issue happens frequently.

Going by articles and videos on you tube, it seems to be firmware issue and should be fixed in software by tp-link. Please fix this and release a new firmware with a fix soon. Not happy with my upgrade to tp-link.
