I've seen exactly the same behavior, and I'm really struggling with it right now. So far, the wireless connectivity leg appears to be the common piece in this trouble.
I've tried it two ways - One all in-network (with only a wireless AP in the mix) and one over the public Internet, with who-knows-what in the mix. Scenario 1- A WinXP SP2 machine w/Linksys wireless USB 54G NIC connecting to an Apple AP Extreme base station, running RealVNC Server 4.1.1. Connecting to it via another WinXP SP2 machine wired to the backbone shared by the AP Extreme. Behavior: VNC Viewer will find and connect to the VNC Server right away. I'll get 10-30 seconds of normal connectivity before the link fails, viewer reports 'reset by peer', the server side (with the USB wireless NIC) drops off and Windows reports the NIC was disconnected and reconnected (not just network, but the NIC itself). Scenario 2- WinXP SP2 machine running VNC Server 4.1.1, Mac OS X 10.3 running OSXVNC server. Both inside private LAN attached to public Internet via D-Link wired router + cable modem. Win XP SP2 laptop attaches to VPN server @ home via broadband service in distant city via built-in 802.11G NIC + D-Link wireless router + cable modem. Behavior: Laptop connects to VPN fine using std. Win XP PPTP. Open cmd prompt and start a ping to VPN server to monitor connectivity. Start VNC viewer and connect to either host (above). Connection stable for 10-30 seconds, then drops (reset by peer) and ping stream shows 'no response' messages, but VPN connection still up. Bouncing VPN clears problem, ping works again, and it all repeats. All these devices work properly over an all-wired infrastructure. Any thoughts? ----------------------------- Chris' original e-mail --------------------------------- I found this was commented on once before when I searched google and saw a few replies. Let me give you the rundown on what's happening. Setup: Desktop running XP home w/sp2, is wired to the Linksys Router. Laptop running XP home w/sp2, is wireless connected to the router. 802.11g -Signal strength was at full, 5 bars, and throughput was at 54mbps. -There are 4 wireless phones in the house, 2.4ghz. I even unplugged them, and removed the batteries from the cordless handsets. -Tried channel 6 and 11, same problems. Linksys Router, it's still setup to basically default setting, the QoS feature is not enabled. Quality of Service, it is suppose to balance out the bandwidth usage over the network, default setting is disabled, so that's not limited the connection speed to the laptop. I have Windows firewall disabled on both machines. Symptom: I am trying to connect to the desktop from the laptop. Once I'm connected, I get about 10-30 seconds before "Error, read: Connection reset by peer (10054)" But wait, there's more...After that error pops up and VNC closes, I get the little windows wireless connection bubble from the system tray saying a connection has been made. Well I thought I had a connection? WTF gives... So I open AOL and run AOL for about 2 hours running AOL Radio, getting constant streaming audio, then I try VNC again. It lasted for 20 seconds, I almost thought it was working...nope. same problem. But, AOL gets kicked off as well, because...the wireless connection is disconnected. By the time AOL flipped out, and the VNC error popped up, the Windows Wireless connection icon in the sys tray had popped up again saying that I've made a connection again. Obvious Theory: When running VNC something causes the wireless connection to drop completely. Duh. But why? And how can I fix it? Anyone? I have not tried this yet, to help confirm its only the wireless causing the problem...Tonight I will connect to the router with the laptop via a Cat 5 cable instead of wireless. Thanks everyone!
