Thank you very much for your explanation. The test with the earlier mentioned Archer C7 V2 was indeed done on an internet connection with far less upload bandwidth. So the bottleneck was probably on the WAN link instead of wifi link, masking the wifi bufferbloat of the client.

Unfortunately, I cannot reposition the antenna, since the router and laptop client both have internal antennas. The 2.4ghz wifi performance of the Mediatek platform is pretty poor in itself, but this is probably an inherent property of the Mediatek platform unfortunately. 2.4ghz performance was definitely way better on the Ath9k platform.

In case it is helpful, related braindump follows, maybe it will be helpful:
When I worked deploying outdoor nodes in campgrounds and such we moved from using long coax antenna cables to putting the AP and clients with external ants mounted up on the poles with a single POE cable for data and power (for non WAN repeaters, just power). The run from the router to the ant was just a ~6" pigtail and gave us several dB advantage of the long coax. With an RF transparent enclosure (I suppose you could get away with tupperware + rtv at the low end; with more frequent inspections) you could put any router up high/outside similarly. Put tiny weep holes (too small for nest building flying insects) in the lower corners to drain any condensate and paint the enclosure with a non-metallic base bright white to reflect UV and heat better if it will be in direct sunlight. Non-metallic box and paint because your antennas are in there and need to "see". We used metal boxes with external antenna connections so I'm winging it on the tupperware/paint thing but most plastics are mostly transparent at 2.4Ghz+. If you go too high in populated areas you pick up a lot of noise from the surrounding area APs and clients on same or near channels and other RF noise sources in the band. Go up just high enough to maximize LOS and minimize longer distance noise from other APs. If you can mount under an eave out of direct sunlight then probably better for both UV issues and heat issues for the router. For ventilation, if required (lm-sensors package is your friend for determining this; or just climb up and check how it feels on hot days), use normal downward facing vent type slits along the top edge of vertical face (to keep rain out) and put window screen behind slits to prevent insect nesting.
