I installed Ubuntu 14.04 LTS alongside Windows 7 about a month ago.
Since then my internet connectivity has been extremely slow. I am connected using WiFi and I have a Intel wireless 7260 network card. Webpages take forever to load. Other devices connected to the same network have no problem at all and my Windows installation does not either. I have been browsing the Ubuntu forums for a while now and have tried a lot of different things such as disabling ipv6 but to no avail.
Edit: As requested:
# /etc/modprobe.d/iwlwifi.conf # iwlwifi will dyamically load either iwldvm or iwlmvm depending on the # microcode file installed on the system. When removing iwlwifi, first # remove the iwl?vm module and then iwlwifi. remove iwlwifi \ (/sbin/lsmod | grep -o -e ^iwlmvm -e ^iwldvm -e ^iwlwifi | xargs /sbin/rmmod) \ && /sbin/modprobe -r mac80211
