Question Why is my download speed so low but upload speed fast?

[Kenjor]

Ever since I got my new computer (custom built) my download speed as been way slow than my other pc (used to be 15/20 mb per second download but now only 1-2 mb per second)

Further more, on the speed tests my download speed reads 1-2 mb while my upload reads 25-30 mb.

I have reason to believe that a program my be throttling my connection speed as every other device in the wifi gets a solid 20-30 mb, however after a recovery speed is still slow.
Please Help.

If you installed the "ROG Game First" software, that may be the reason. Many of the network optimizer software packages do things like this to "optimize" for gaming network traffic.

I've searched around for that program and I can't find it nor do I remember installing it,
However I Definantly do think a similar program may be installed as I bought the pc prebuilt.

Any suggestions?

Boot up into Windows Safe Mode and try your download speeds then.
This way you will know if its Windows main problem or not.
If it's faster while in Safemode, then its definetly something in software installed on your computer.
If it's still slow, then it has to be something else, maybe hardware?

I tried booting into safe mode but that doesn't allow me to connect to the WiFi through the wireless adapters because they don't show up in safe mode

Is there a way to connect to WiFi in safe mode?

Still can't get my pc to connect to WiFi in safe mode, any suggestions?

Never mind guys I sorted it out.

Downloaded driver booster and updated all of my drivers, after that a clean 90mb download speed.
