When I use a ethernet connection to the internet and work on battery power, my internet speed is around 30 Mbps, if I plug in the charger (AC-power) this speed drops to around 5-6 Mbps. When working wireless I don’t notice any difference. I really don’t understand how this is possible. Can someone explain and perhaps point to a solution?
Laptop: Acer E 15, Windows 10, 8Gb memory, Realtek PCIe Gbe family ethernet card.
I found a solution that worked for me, and maybe it will help others. I had the exact same problem mentioned in this question: WiFi speed normal (at the max of my plan) when laptop was unplugged, then as soon as I plugged the charger into the battery immediate horrible drop in speed (1/10th the speed or worse than what it was just moments before). The problem was easily to duplicate. Plug it in, SLOW. Unplug it, FAST. The connection between my actions and the result on the WiFi speed was impossible to write off as mere coincidence. The solution offered by Gajendra Parmar did not help. My settings were already set to what he suggested and changing them to anything else made no difference. Also I had the latest drivers, and the issue could not have been a weak signal since I am within an arm’s reach of the router. However I found a 2013 forum post on HP’s website about a similar problem. The suggestion offered did not apply but had to do with the Power Plan, so it made me look into those settings on my laptop. Here’s what I did to fix the problem:
Open: Control Panel\All Control Panel Items\Power Options\Edit Plan Settings
Click on “Change advanced power settings”
Expand “Wireless Adapter Settings”, then expand “Power Saving Mode”.
Changed the “Plugged in” setting to match the “On battery” setting.
Clicked OK.
Hello! Go in the power options and in “Wireless Network Adapter Settings”, put on maximum performance at the electrical outlet!
