Wifi is excruciatingly slow on only my home network with Intel 7260

I have the Intel 7260 AC wifi card and  I have a throughput of 150Mb/s, and on wifi I expect to get at least 20Mb/s. This was true with my laptop both when it was running either Windows 8.1, or Linux Mint, it would consistently get 20Mb/s down or more. But, after switching over to Arch, I almost always get 100-500kbps, with a latency that varies around 400-3000ms and I have been struggling to barely get to 3Mb/s, and that is after rebooting the machine or the wifi card. I have the latest updates from the Arch repos and I also have turned off the power management feature via inserting this line of code into /etc/udev/rules.d/80-iwlwifi.rules:

ACTION=="add", SUBSYSTEM=="net", ATTR{address}=="<mac address>", RUN+="/usr/bin/iwconfig wlp2s0 power off"

Also, here is the output of iwconfig:
   

wlp2s0    IEEE 802.11abgn  ESSID:"404-ERROR"  
          Mode:Managed  Frequency:2.462 GHz  Access Point: 44:94:FC:50:33:D6   
          Bit Rate=54 Mb/s   Tx-Power=22 dBm   
          Retry short limit:7   RTS thr:off   Fragment thr:off
          Power Management:off
          Link Quality=70/70  Signal level=-38 dBm  
          Rx invalid nwid:0  Rx invalid crypt:0  Rx invalid frag:0
          Tx excessive retries:4  Invalid misc:5129   Missed beacon:0

As you can see, the power management is turned off, and I can't figure out what else is wrong because my wifi seems to work fine on other networks, such as my school's, where I get 100Mb/s down on wifi. Do you guys have any suggestions?
