Hello everybody and thank you for trying to help, here is my problem.
I have 2 desktop PCs connected to the same router, PC1 via wireless, PC2 via network cable.
PC1 has 7000-10000kb/s download speed but 1000-1500kb/s upload speed.
PC2 has 7000-10000kb/s download speed and 5000-7000kb/s upload speed.
So my question, why PC1 has slower upload speed than PC2?
