Solve : LAN Keeps Dying...?

1.	Solve : LAN Keeps Dying...?
Answer» I'm using Windows XP SP2 and have Windows firewall ON. I have a small network set-up at my home. Three computers, each receiving my cable internet through my Belkin 4-port router. It seems, at random, my connection will be lost. I have my network settings displayed in the taskbar, and it seems like dozens of times a DAY I'll get the error, "A network cable is unplugged." Almost instantaneously, it will find the connection again. This probably doesn't sound like a problem, but, although I'm imediately connected to the network again, it takes a while to start receiving my internet feed again. (Probably about a minute?) This is extremely frustrating when using a chat client like AIM and MSN, and having all of my conversations wiped out because of a lost connection. One thing that I could think of that's causing the problem: I'm using the P2P client "Azuereus," and I have opened the port 6881 on both my router's firewall and Window's firewall. Opening this port increases download speeds exponentially, so I consider it a necessity. While I said it usually takes a minute to start receiving my cable internet connection, there's something that makes this a little stranger: when my computer is idle, I'll lose the connection...and it won't get it again. If I'm download something overnight, it seems it'll go for maybe 15 minutes, then the LAN will be disconnected. When I wake up and turn my computer monitor back on (it auto-shuts down with power save), I usually am greeted with the "network cable unplugged" message. It's like it hangs at that part of the little "cycle." (By 'cycle' I'm referring to the disconnect, instantly re-connect, wait a minute for the internet...etc that's just been plauging my computer). Any ideas? Maybe conflicting firewalls? I don't know. I'm just really frustrated right now. I've ran NortonAnti Virus, SpyBot Search and Destroy and Ad-Aware -- all with most recent updates -- and eliminated anything that I thought could possibly be doing this to me. Help!

I'm using Windows XP SP2 and have Windows firewall ON. I have a small network set-up at my home. Three computers, each receiving my cable internet through my Belkin 4-port router.

It seems, at random, my connection will be lost. I have my network settings displayed in the taskbar, and it seems like dozens of times a DAY I'll get the error, "A network cable is unplugged." Almost instantaneously, it will find the connection again. This probably doesn't sound like a problem, but, although I'm imediately connected to the network again, it takes a while to start receiving my internet feed again. (Probably about a minute?) This is extremely frustrating when using a chat client like AIM and MSN, and having all of my conversations wiped out because of a lost connection.

One thing that I could think of that's causing the problem: I'm using the P2P client "Azuereus," and I have opened the port 6881 on both my router's firewall and Window's firewall. Opening this port increases download speeds exponentially, so I consider it a necessity.

While I said it usually takes a minute to start receiving my cable internet connection, there's something that makes this a little stranger: when my computer is idle, I'll lose the connection...and it won't get it again. If I'm download something overnight, it seems it'll go for maybe 15 minutes, then the LAN will be disconnected.

It's like it hangs at that part of the little "cycle." (By 'cycle' I'm referring to the disconnect, instantly re-connect, wait a minute for the internet...etc that's just been plauging my computer).

Any ideas? Maybe conflicting firewalls? I don't know. I'm just really frustrated right now. I've ran NortonAnti Virus, SpyBot Search and Destroy and Ad-Aware -- all with most recent updates -- and eliminated anything that I thought could possibly be doing this to me.
