I will try to explain this the best way I can, cause it's a bit complicated. I have Windows XP, Professional. I am the only user of this PC. I have recently installed a DSL router, along with a new DSL connection (a month ago). Also, I have installed Skype, and i have MSN as well and Emule. (These are the programs I mainly use). The thing is that when I made some settings to my router for emule to work better (i.e. I have assigned 2 ports so that i can have a high ID in emule), ever since I have this problem: If I turn on emule and then close it, Explorer, Skype and MSN cannot connect to the Internet, and only emule can reconnect. If I turn on my PC, and open only Skype or MSN, it connects for some minutes, I can send and receive messages (this goes for MSN as well) and then I lose the connection and Explorer stops working too. By "stops", I mean that I see that I am online but I do not see any pages ( I get the blank page) or receive or send messages. So basically, everyone else sees me as offline, when I see that I am online. I have contacted my Internet provider and they say the line is fine, without any problems. I should point out that the router is working fine, the line does not disconnect and only rebooting the PC or shutting down the router can correct the problem for 4-5 minutes only.
Can anyone please tell me what could be a possible reason for this? Where can I look to locate this problem?
Thank you so much!
