I noticed reconnecting to a wireless network after waking my Vista laptop from sleep was delayed. Also, running Internet speed tests showed slower rates, both over WiFi and even connected via Ethernet cable. I had been adjusting cabling and my router, so I had thought the problem was in that.
In the end, resetting networking components in Windows fixed all the problems. I gained 3000 Kbps in speed to match the cable Internet service I pay for. If you are having similar problems, try running the following Netsh commands from an elevated command prompt and then restart your PC:
- netsh winsock reset
- netsh int ipv4 reset
- netsh int reset all
Run the following from a command prompt:
netsh wlan show networks mode=bssid
