Hi,
The game used to run fine around 4 months ago (did not play in between), using same laptop and same router, but now when i play, there is a lot of lag for the first 7-8 min of game time, then it runs smoothly. windows firewall is off.
No player is fp to me, all their pings are below 350, still lags in game. PC is windows 7, 4 GB RAM.

hi
try deleting all the old temp saves here:
C:\Program Files\Microsoft Games\Age of Empires II\SaveGame\Multi
C:\Program Files[86]\Microsoft Games\Age of Empires II\SaveGame\Multi
check your anti-virus, see what its scanning in real time and allow the game/voobly through it.
do a virus/trojan scan of the pc.

I deleted all old stored game files, still it does not work. Also ran the antivirus, no malware was found. Can it be solved using port forwarding? If so how to do it?

hi
it shows you are connecting thro' 16000udp. how ever if you havnt forwarded that port, you can do so and see if it helps.
