Learn how to fix slow internet connection with Windows Vista
by windshell / General
 The most recent OS from the Microsoft lab, Windows Vista brought not only many improvements, but also many headaches. One of them is problem with a slow connection. There are some ways how to fix it. There are many reasons for slow connection in Vista. Sometimes you have to clean the browser of unnecessary load, which can be reason for slow connection, and delete all cookies, history and temporary files. If you use Internet Explorer in Vista you should do following: To delete cookies
To clear History files
To delete Temporary Internet files
Malware and Viruses as a reason for slow connection Malware and viruses are often reason for slow internet connection. When your system is infected with a virus, it installs code which will usually send copies of itself through email. Some viruses can multiply at the rate of hundreds of email messages per minute, which leaves little or none bandwidth for anything else. That can cause a major slowdown or even non-responsive PC. Viruses often do not give any obvious indication that they are running, so it is best to run your antivirus software at all times, especially if it has resident scan and protection. Sole antivirus won’t be enough for protection, so you have to run anti-spyware scan. Also, it’s good idea to have installed and enabled firewall as a protection. However, firewall can also be a reason for problem with a slow connection. Maybe this sounds radical, but try to disable or remove Firewall if you have it installed, or its particular features that can cause slow connection, at least temporarily to check if there are any improvements. Hardware Drivers as a reason for slow connection Cause for slow connection can be a problem with Vista drivers for some Network Cards (especially Realtek cards). Rolling back or updating your driver or reinstalling your network card are possible solutions. Update and Reinstall are easy to perform, but there is how you should perform driver roll back:
Windows Vista Networking features as a reason for slow connection It’s useful to know that Vista added support for IPv6, improved network protocols for faster detection and transfer. In theory this should take Internet connection to the next level, but in practice it slows down not only connection, yet whole system. So, this could be reason why your connection in Vista is slowed down. You can perform these 5 steps to improve your connection speed: 1) Turn Off Unnecessary Network Protocols - Turn off unnecessary protocols such as IPv6, Qos Packet Scheduler, File and Printer Sharing or Link-Layer Topology. 2) Use Static IP - Try to use static IP, assign an IP to your computer, don't rely on DHCP server to assign IP for you 3) Use OpenDNS - Replace your ISP DNS server with OpenDNS, or any faster DNS server. To do that do following:
4) Increase local DNS cache - Vista captures every DNS records you access, so increasing the cache size will minimize the needs to query To do that:
CacheHashTableBucketSize = 1 CacheHashTableSize = 180 MaxCacheEntryTtlLimit = ff00 MaxSOACacheEntryTtlLimit = 12d 5) Turn off TCP Auto Tuning - This might be the major reason for slow connection. Try to disable it or other settings. You need to manually configure TCP settings if you disable this function. Use this commands: "netsh interface set global autotuning=disable" to turn off Auto Tuning "netsh interface set global autotuning=normal" to turn it back on These were some basic steps and ways how to fix slow connection in Windows Vista. We hope that at least one can help.
