Internet works fine still cannot connect

[Justforcause]

I have an annoying issue with my internet connection. From time to time i can't connect to Steam, Battle.net or download from torrents (I'm mentioning torrents becuase there might be a connection). I share the internet with 10 other people all of them connected mostly via wi-fi. Is is possible that the connection is too low to connect to the already mentioned above servers? There is nothing wrong with my pc or internet settings because it works fine for a week and then all of a sudden not. Once we tried to hard reset the main router and after that it worked just fine.
Realy don't know what might be the reason and I would love to finally find out what's causing it.

Thank you all for any help.

If 5-10 people are trying to use the internet at once -- especially with torrents, which are a real router workout -- your poor crappy router is probably running out of RAM/horsepower. Either that or your torrents are saturating the uplink, preventing more important packets from getting out.

You need a router with better specs, stable firmware, and good QOS.

Thank you, finally a concrete answer.
Actually I don't care about the torrents and I also think that noone is downloading from torrents at the moment. I just said that because when I cannot connect to battle.net and Steam, torrents usually don't work either.
I would like to connect to Battle.net and Steam. And tell me if I am wrong but youtube, online music etc. are draining the internet more than just playing WoW and such.

Yes, they are, but without QOS everything has the same priority.

You still haven't offered the most important issue, which is what exact model of router you have.

Should I tell you the main modem where the main cable of internet is connected or just the router? The router is http://www.planet.com.tw/en/product/product.php?id=34631
As for the main modem I would have to find out.

Thank you very much for help!

Almost certain it's the router and you need a better one. Do you not live in the US?

No I don't. Can I set anything in the router settings that could be beneficial for my connection? I tried forwarding ports - doesn't work. Maybe decrease speed of wi-fi somehow? I am connected via cable so it wouldn't affect me.

Maybe Bandwidth Control Rule Settings something with this option?
