Problem with co-op

Hello, I'm new on this forums. I'm sorry if I choose wrong section, but I think it will suit my request best.

I have problem with co-op, I have read all rules of co-op playing, but it doesn't help me. After I reach 30-40 level, I'm not seeing any summon signs, and mine summon signs are almost always ignored. I made new character, cleric, and I could play on co-op, until 40th level, after that I don;t see anything. All my characters has a problem, also my wanderer on 87th level and second wanderer on 75th. They all can't play on co-op, and I don't know why. But I get invaded quite often, and all other forms of online play work.

It depends very much on the areas you're attempting to be summoned at.

For Level 40, Anor londo is the best. On your 75 and 87 characters, the Kiln or Four kings is your best bet.

You have to adjust depending on what level you are. If you're overlevelled for where you are, you can find it difficult to find coop signs.

Hope this helps clarify a bit. Where are you trying to get summons for on you?

That is probrably because where you are there aren't any players who are in your level range the formula is rought (x+10+ or - 10%) Where x is your level. since your are level forty then you can be summoned by anyone between the levels of 26 and fifty four and it takes a while to get summoned unless you are in undead burg. And it is also possible you are just too high level to be summoned in this area.

Damn it... I'm after Ornstein and Smough fight with these 87 and 75 chars, and need humanity like a hell (almost 30 to unlock fog doors in Chaos Servant Convenant to save Solaire). I just need help with Four king 'couse Seth The Scaleless is too hard and accesing demon ruins may kill Solaire. What should I do? Get higher level or try to do all this alone?

P.S. I usually get places to leave summon signs from wiki.I'm trying to be non-trolling player.

around 80 you should be able to get help on every boss past anor londo, so i don't see why you're having a problem :| It may be your connection, or you could try as a better time during american evening when loads of players get on.

Well if you need humanity an easy spot to farm it is the depths, rats drop humanity and if you have the gold serpent ring you should be able to get enough in no time. If you need help with the Four kings I do have a toon at SL 75, but make sure you really need the help...I really hate that boss with a passion, and like to avoid him when I can. So much pain. Seath I can't really help with seeing my character is an int toon with all magic reliance, so Seath will take little damage from me.
