Slow WIFI connection on MacBook air M1
Is anyone aware of an intermittent slow wifi problem on mac book air. Every now and then my m1 MacBook air running on Big Sur 11.6.2 suffers from an unusably slow wifi connection. when this happens other mac's in the household are running fine so its not anything at the router end. I even loaded up my old MacBook pro 2011 version and that worked fine whilst my fairly new M1 Air could not even load a web page. Not certain but It seems to happen after I have been using an ethernet cable connection via a plugable multiport extender for a while and then switch back to wifi. Its intermittent and maybe only once every couple of months which is odd. The only way I can fix it is to restart the mac, then everything is fine, but clearly not what I expect from a mac. Also it did not use to happen on previous machines I've had, which I used in the same way so seems to have been introduced on the M1 or the more recent O/s's.
Has anyone seen and overcome something similar.
MacBook Air 13″, macOS 11.6
