@ect76 Install one of the band-select enabled beta firmwares and try locking to band 3 or 1. The MR600 is known for it's problems picking the best channel. Could even be locking to band 20 (only 5Mhz...

@niemals_sebi can only speculate, if TP-Link know they aren't saying (or fixing it). It usually means bad memory management. On the MR600 that's compounded by not having enough RAM to start with &...

QoS isn't designed to arbitrarily throttle connections. It's designed to prioritise important ones. AFAIK there's no quota management support on the MR600, it's only a low end router bolted onto a...

@dvyx That sounds exactly what you'd expect from QoS. It should only limit bandwidth IF something higher priority needs it. TBH I'm surprised, I've never seen it work that way on my V1 and others...

WiFi bandwidth 300Mbps over 2.4GHz, 867Mbps over 5GHz You won't see that in real life use, even sitting next to this router. Use it wired or replace it.

And already reported as not supporting SMS, despite that bug being fixed in a beta a year ago. Just more chaff to distract us from their utter lack of effort supporting the V1.
