sleet storm knocked out wifi completely, help?

hi, i own the nvg589 and it started acting weird after a small sleet/snow storm. sometimes, only the power light will be on. other times, the broandband light will flash red and other times al lights are green but wireless is flashing green. 

i tried resetting the router and unplugging it for a few minutes. nothing seems to work and all the cables are in good condition and plugged in the right places. what am i to do? this problem has been going on for three days now, and i need internet now.
