After trying it on a different network I found that I did not have any limited connectivity issues. However the network was an 802.11b only. I have not tried this out on a different 802.11n network.
The Broadcom wireless adapter was a two antenna version so I added an additional antenna when going to the Intel wireless adapter.
Sony did not recommend this adapter. The recommendations came from other Sony Laptop owners.
I have not seen any other events repeating in the event viewer but will check again and let you know.
