microSD card causing WIFI connection slowdown while running of batteries

[clrk9000]

I just noticed that if I install the microSD card the wifi connection will go down from 300mbps to 6.5mbps. I have not experienced any WIFI Limited issues in 5 hours of use.

I am using Linksys EA4500 and Lexar microSD 32g.

I have no idea what is the connection but just noticed that removing the microSD card seems to fix the problem.

This is the first time that I have seen anyone reporting anything like that. Try this:

Enable Hyper-V to expose advanced power options settings, restart, open power options, click change plan settings, click advanced settings, expand wireless adapter power settings, change to max performance. Disable Hyper-V and restart.

Welcome to the forum

What you describe could possibly indicate an issue with the SD card as well. You may want to see if there is a corruption by testing the disk.

Thanks ctitanic and lesshor.

Yes, it is a damaged microSD card. My surface pro 3 is back to its old ways of Wifi Limited and 6mpbs speed when on battery.

Setting to max performance seems to work. I am just worried that the fan just keeps on running all the time.

Have you tried rolling back to the previous version of the driver? I did this via device manager and WiFi seems to work fine and I only hear the fan under intense loads.
