Before Windows 7 (i.e. on Windows XP Professional) on the same Internet Connection (a Mobilink Infinity Wifi Broadband Connection) I was having a great Internet surfing and downloading experience. So finally after some 2 months of suffering, I finally decided to see if I was the only one suffering from the same issue and thus decided to do a Google Search and found out that I was not the only one with the help of Google Suggest, so instead of writing my own search query I decided to go with Google Suggest and searched for "slow internet windows 7".
So the first article that came up in search at that time was Microsoft's own explanation in the form of an article titled "Why is my Internet connection so slow?", after skimming through the article I found that this was of no use to a tech user as he would have already checked and made all the suggestions provided in the article. Then I found two really helpful articles on "Microsoft Social" which were "Painfully slow internet on Windows 7" and "Slow Internet and Page Timeouts". Although the second article was intended for Windows Vista, but works for Windows 7 as well. Here I will summarize only the key points from the two and will try to make them equally useful for both teach and general user. Please be advised not to make any changes to the Windows Registry without proper backup or supervision and better to try out all the other suggestions leaving registry as the absolute last resort.
Use Selective Startup (Clean Boot)
- Click Start, click Control Panel, click Administrative Tools, and then double-click System Configuration.
- Click Continue, or provide Administrator credentials if prompted.
- Click the General tab, and click Selective startup.
- Under Selective startup uncheck Load startup items.
- Click the Services tab, check the Hide all Microsoft services box, and then click Disable all (not necessary to disable all services but a few that take up internet or network resources. On Dell its found that "Advanced Networking Service" by Dell is found to cause the problem).
- Click the Apply, then OK, and then Restart.
Use Fix it For Me or Fix it Yourself
Try uninstalling IPv6 on all interfaces, removing any IPv6 virtual adapters, and resetting the TCP/IP stack. To remove IPv6, go into the properties for each network adapter and either uncheck the box next to the protocol "Internet Protocol version 6 (TCP/IPv6), that will disable it, or select it and click uninstall, which will remove it off the computer. Then go into device manager and remove any 4to6 adapters, WUN miniport adapters, or tunnel adapters.
NOTE: You should do this for each network connection.
