Vista Problems 5 Steps to Fix Slow Internet Connection
Step #1 - Turn Off Unneeded Network Protocol.Try to turn off unneeded protocol such as IPv6, Qos Packet Scheduler, File and Printer Sharing, Link-Layer Topology.Step #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.Step #3 - Use OpenDNS.Replace the ISP DNS server with OpenDNS, or any faster DNS server (You need to try them before you know). Go to Control Panel -> Network or Internet -> Network and Sharing Center -> Manage Network Connections, select and highlight the connection, then right click and select properties.Uncheck any unwanted protocol. Highlight IPv4 and select properties, set the IP address and DNS server accordingly. Use 22.214.171.124, 126.96.36.199 for OpenDNS server.Step #4 - Increases local DNS cache.Vista will capture every DNS records you access, by increasing the cache size will minimize the needs to query.Go to registry HKEY_LOCAL_MACHINESYSTEMCurrentControlSet Services DnscacheParameters, create or change the value below, all in hexadecimal:CacheHashTableBucketSize = 1 CacheHashTableSize = 180MaxCacheEntryTtlLimit = ff00MaxSOACacheEntryTtlLimit = 12dStep #5 - Turn off TCP Auto Tuning.This might be the major reason, try to disable it or other settings. You need to manually configure TCP settings if you disable this function.Use this command "netsh interface set global autotuning=disable" to turn off auto tuning, "netsh interface set global autotuning=normal" to turn on auto tuning. All command must run as Administrator.
<p>Every time I try to go online, I get a blank window that says "unable to connect" or "unable to find a web page". I unplug and replug my modem (cable). The dialog box usually says "gateway not available". I then ask to explore other options. This works most of the time (not always). Why do I always have to go through this? What do I need to do to troubleshoot this and how do I do it?</p>
Besides the fact steps 1, 2 and 5 do not tell me exactly how to do the things you are telling me to do, I turned off my starting programs & the problem with my internet persisted & is preforating outside the internet. (ex: I go into my control panel menu & it is lagging sevrely as well). So it was none of the startup programs. This problem does not go away when I plug my Inspiron 1525 into a ethernet cable either! And when I run the diagnostic tools it claims everything is fine harddrive, cpu, cards, internet ports, wireless you name it!
BUT let me be clear that I find it extremely interesting this sudden severe internet lag & malfunctioning DOES NOT IN ANY WAY AFFECT THE DELL WEBSITE! This website loads & functions normally support, diagnostic tool & all! If I switch tabs to a non-dell site the problem persists, if I swtich tabs between dell websites there's absolutely no problem. So how is this possible if my whole internet is just lagging & malfunctioning?
