Hi. I have an Aspire e5-571, which has a Broadcom 802.11n network adapter. It has an infuriating habit of suddenly going into very low download speed (3 or 4 Mbps) after running at 40ish Mbps. Often the upload speed is OK. The only way to restore the speed is to reset the adapter. We have tablets, phones and another PC that work consistently at high speeds so I have ruled out the router (it happens on 2 different routers anyway). I have updated the adapter to the latest drivers, changed various settings in the adapter, moved the PC closer to the router, all to no avail. Does anybody have any idea what is going on here? Any logs I can check for more information?
