What Barca said.
Try to dung with Nesters, as w117 tends to have... noobs.
Yell in SN for a team before you try out w117.
One thing that really helps me is keying myself. It gets really frustrating when others key badly.
As for weapons and armour:
If you can, get a friend to make you a prom 2h, and set your ring to berserker. Prom plate is also helpful, until you land a Shadow Silk Hood.
I also bound some gorg arrows as sometimes you need to range bosses.
So three things to bind: Prom2h, promplate(or SSH), and gorg arrows.
At the start of every dung, try to be fully equipped with a toolkit, laws, cosmics, and astrals (if you want to cure).
And listen to the keyer. That always, ALWAYS speeds dungs up.
Hope this off-the-top-of-my-head tips helps
