[ASK] A problem with iwlwifi on Arch Linux.


Hello everyone, I am in Vietnam. I have a question about my wireless card.

I am using DELL Inspiron 5448, Arch Linux x86-64, with 

"Network controller: Intel Corporation Wireless 3160 (rev 83)"

Everything was good when i booted on Live CD. I can access internet from wifi normally.

But, after I install it on hard disk, i can access internet from wifi but ping is sometimes above 1000ms or 2000ms even above 10000ms . At the moment, my android phone can surf normally so i have to connect my phone to computer and use "USB tethering" to connect the internet.

I am so sad with my computer's status.

I hope there is a way to fix this problem.

Thank everyone !!
