Ohayo!

So I have looked around on the wiki page, and also here on the forum but havn't found answers on my question.
Seems I have some problem with a port on Utorrent, and I'm just wondering if It's a big deal or something I really should try and change. According to the message on Utorrent this is what I get "Not connectable - A firewall/router is limiting your network traffic, You need to upen up a port so others can connect to you.
To give you some information:
OS: Windows XP SP3
utorrent client: 1.6
AVG Firewall (disabled)
Windows Firewall (disabled)
Router: Netgear RP614v4
I have tried to login to my router at 192.168.1.1 and login in with admin / password
as default, but seems like I can't get in. So off to my question, as first then is it really necessary to open up the port that utorrent is suggesting?, will it make a big difference? And what port should I use on utorrent?
Also seems like I most reset my router to be able to login to it, and open up the port, but which port should I use at utorrent in the first place?
Thanks.
Edit: My port issue is now fixed, though a new problem has evolved... Posted it further down in this topic to prevent to spam topics. Have been checking the wiki about this, but havn't been able find anything about this issue. Might be lookin at wrong places, but if you might know the issue please scroll further down the topic, thanks!
Edit: Think I have found the issue of my other problem now, was searching some more on the forum and find someone with the same problem as me. Since I recovered my uniqe passkey it seems that I most download all my torrents and torrentfiles again for it to work, since I got another passcode now. Tried it and It's working while downloading now atleast. Just gonna wait to see if my uploading works aswell. I'll keep you posted.
