Slow internet using Arch Linux

Solution 1:

Here are some things to try:

Ping the IP directly (i.e. ping 8.8.8.8). Is the responses quicker? If yes, it's probably a DNS issue.
Connect via an Ethernet cord (Wired). If the response is quicker you might have a driver issue or some software issue concerning your wireless card.
Run wireshark and then ping. Is your ICMP package sent at all? This will display some wireless network issues.
Run strace ping 8.8.8.8, by looking over the output you'll be able to determine some software issues (like, not being able to bind to a socket).
