while collecting wifi packets from my mobile phone (from a linux vm running wireshark on my laptop), I noticed, while collecting packets, the phone began having difficulty connecting to various network services (IMAP, Activesync, pings to local network and remote addresses...etc). Once I stopped collecting packets, the phone network operations began operating normally. This was repeatable. Any idea what is causing the phone TCP/IP problems while collecting packets via wireshark ?

Some additional detail: wireshark 1.2.11 Ubuntu 10.10 WPA2 PSK Android IP 192.168.200.112

wlan1 IEEE 802.11bgn Mode:Monitor Tx-Power=27 dBm
Retry long limit:7 RTS thr:off Fragment thr:off Power Management:off

My wifi adapter for capturing is a NETGEAR WN111 v2 300Mbps 802.11n Wireless LAN USB 2.0 Adapter

thanks Tim

I see a lot of TCP DUP ACK ; TCP Retransmission ; TCP Out-of-order packets when using a display filter of ip.addr==192.168.200.112

further testing ; using wireshark 1.4.4 on my laptop (no vm involved) and using an AirPcap adapter ; there is no affect upon the phone's network connections when capturing packets

The TCP DUP ACK ; TCP Retransmission ; TCP Out-of-order packets don't appear to be related since I still see them
