I got my combo plan converted to standalone thunder plan and the phone was taken away before couple of days ....my net worked fine that day but it is not working since yesterday...Iam getting blank default gateway in ipconfig in cmd....i remember taking away my laptop charger which is plugged near my router and other wires yesterday in a hurry which might have maybe caused some problems in wiring...I don't know if the problem is from my end(wires) or their end because of removing the phone..Ps: i am a total noob when it comes to networking etc...
