Windows 7, Vista, 2008 Tweaks
by Philip (153 comments)

Windows 7 TweaksWindows Vista introduces a number of new features to the TCP/IP stack, including CTCP, and TCP Window Auto-Tuning. This new implementation works much better by default than previous Windows versions with broadband internet connections, and is able to adjust the RWIN value on the fly, depending on the BDP (bandwidth-delay product). This, however, introduces some problems with older routers and restricts the user from tweaking some of the TCP/IP parameters. Still, there is always some room for... »

How to set a Wireless Router as an Access Point
by Philip (223 comments)

ipconfigI've often found it useful to get just the wireless functionality out of a WiFi router and reuse it as an access point. Wireless routers seem more common, and are often priced even lower than wireless access points. Adding an access point to a wired network already in place, or to one where the main NAT router is provided by the ISP is usually the easiest solution. However, introducing a second NAT router on the network is not a good idea, especially without some tweaking to set it... »

Gaming Tweaks
by Philip (25 comments)

Online Gaming can often benefit from some fine-tuning of Windows TCP/IP settings and the Network Adapter properties. This article is intended to supplement our general broadband tweaks and list only TCP/IP settings that are specific to online gaming and reducing network latency. Some of these settings are also mentioned in our general tweaking articles, however, the emphasis here is on latency rather than throughput, and we have complemented the tweaks with more gaming-specific recommendations... »

Windows Vista tcpip.sys connection limit patch for Event ID 4226
by Philip (19 comments)

Microsoft enforces a limit on half-open TCP/IP connections that is hard-coded in tcpip.sys. The maximum simultaneous half-open (incomplete) outbound TCP connection attempts per second that the system can make is intended to limit the spread of malicious viruses and worms, as well as limit the possibility of launching a DDoS attack. However, it has proven to also limit some applications using many TCP connections, such as P2P and P2PTV programs.When the OS reaches the half-open connection limit,... »
