Tom,
It's DHCP server
.
There are many issues with the IP stack in Windows. When certain pieces of malware "attach" to your Windows installation, one of the first things many of them do is attack to the TCP/IP stack to subvert DNS and redirect name lookup traffic to a DNS server that will return erroneous (i.e. more malware, advertisements, bad Windows Updates) traffic to it.
Running "netsh winsock reset" restores the TCP/IP stack to a known good state without malware or the "hooks" that would point to the DLL files and executables that malware uses to redirect traffic.
If you don't run this after removing malware, your TCP/IP stack may be broken due to those hooks existing and pointing to nowhere.

I have seen some routers make the connection (ie 54 Mbps), but the DNS server refuses to lease an IP address. The solution was to power cycle the wireless router.
Don't know why. Never had sufficient time to learn why. But if you are having the same problem, the Geek squad would never see the problem and still charge you.
First suggestion: determine if the problem is in the router. IOW any computer that has not connected wirelessly to that router in over a day would demonstrate the same problem. (Any computer connected wirelessly in less than a day may not see the problem.) If both connect at some speed but will not talk, then you have saved yourself a payment to the Geek Squad.
A second suggestion: enter "IPCONFIG /ALL" in the same command window where "netsh winsock" was entered. If the IP address for your "Wireless Network Connection" does not start with 192.168.xxx.xxx or 10.xxx.xxx.xxx, then an IP address is not provided by the router.
A computer can connect. But without an IP address, it still will not communicate. Later in the day, that routers DNS server can fail. But your computer would continue to work for the next 24 hours - when the lease for the IP address expires and it was ask the router's DNS server for an new address lease. No new lease from a failed DNS server means it would again connect only to the router at 54 Mbps, but not connect to the network.
