Hi,
also check what other electrical devices are running nearby
(e.g. microwave ovens are killers of wifi signal, but others
like neon lights can influence it too).
2,5 ghz signals normally are more resilient to obstacles like armed concrete
walls meanwhile 5ghz is not so resilient but faster at least in theory.
One more check is to see what parameters the loaded kernel modules
for the wifi adapters support and what they do (modinfo), experimenting with them
can help improve stability.
Check if any firmware files are loaded for the adapters in the logs
(dmesg) anf if there are any newer files (packaged in backports
repo or on the kernel.org site).
Last resort is longer antennas with higher signal gains which can
be bought on the web or directional antennas that bundle the
signal only towards the access point that can also be bought
or if you like it DIY.
