Yep the settings are obtaining the IP address and the DNS address automatically. The router is set to enable the DHCP server and to have a max of 50 users. I bumped it up to 54 wondering if it was consecutive users (maybe its the 50th user? ) but it made no difference.
Not sure about homegroup. When you try to connect it asks if you want to turn on network sharing or not, neither option makes any difference. It says that there is no homegroup on the network under Network and Sharing.
I did set the IP/dns manually in the Adapter properties. I got 5 minutes of internet then it threw an error, and enabled DHCP and cleared out the fields. Reentering the numbers in failed to get a connection.
Around that time "Microsoft kernel Debug Network Adapter" popped into the Network adapters Devices. I googled it and found that it needed to be disabled. So its now disabled.
There are 5 network adapters 2 Bluetooth 1 Broadcom Gigabit ethernet a Disabled MS one above and the Qualcomm Atheros ar5bwb222 Wireless network Adapter. Version 10.0.204
