Solved! WiFi Download Speed Capped at 5Mbps

[anderson.james2090]

All of a sudden the WiFi download on my personal Dell laptop seems to be capped at 5 Mbps on a connection of 40 Mbps. Laptop is right next to the router. I was getting 40 just few days back.

I'm getting 40Mbps on all other devices & getting 40 on the laptop via Ethernet. Just not on WiFi. Same cap when connected to hotspots as well, so it's definitely something with the machine. The upload seems to be fine.

Things I've tried:
> Update the Wireless card drivers from Intel & Dell's sites to latest.
> Flushed DNS & all the cmd prompt commands to renew everything
> Uninstalled & reinstalled wireless card several times
> Reset the settings on my router
> Reset wifi settings several times

I'm pulling my hair out. Please help.
P.S: I know the difference between MBps & Mbps. All references are in Mbps.

Might be the wireless card has gone bad. You can get a replacement for cheap on Amazon so it doesn't cost much to try that fix.

It's sounding like either a failure with one of the cables or the card itself. You've gone through all the hoops besides replacing it, I think that may end up being your next step.

Did you already check the settings for the card through Device Manager?

True. That would be the last resort.

Yes, played with all the settings. Probably hardware failure I'm starting to believe.
