I am troubleshooting wireless connectivity problem in my home network. My Thinkpad X200 laptop which use Intel Wifi Link 5100 AGN is not able to surf the internet stably. Sometimes it works, but most of the time it couldn't load the page completely or not loaded at all.
This is not happening to my desktop PC which is connected to the same D-Link AP as well.
I managed to capture network traffic on my laptop with Wireshark which results in the image below:
From what I know, the black-background rows show that there are erros in TCP checksum / Bad TCP. Is this normal on any wireless network? If not, how can I fix my laptop so it can surf the internet stably as my desktop PC?
Edit: I tried to capture the TCP packet again while the page failed to completely load. It looks like this is related to massive "TCP Retransmission" in Wireshark logs somehow ..
Edit 2: Gave up on investigating this. Tried another ACP. Luckily, it works without those many retransmission message o__o' Many thanks to everyone for the answers!
