Sometimes when i play dota, my ping would jump to 3000 for no reason, theres no one else loading, im the only one using.
Internet will be not usable as well, sometimes showing limited connectivity.
restarting the modem would not help as well, just have to wait for a very long time for it to be over.

Using everything TM provided me, my modem is grey in color, not the orange one.

is it because im using wireless? will a wired connection fix my problem? or modem settings?
