First of all, you should check your network firewall.

If you set network firewall improperly such as too high security rank, forbidding browsing IE accidently or wrong firewall policy. It may hinder you to open the website.

So, you can try to lower the security banks, check the policy or close down it directly to see whether it can get right or not.

Second, there may be something wrong with your system files.

Any changed or broken Internet Explorer files can have influence on IE. At this time, you can use SFC or scannow order to restore it.

Third, it may be the problem of Internet Explorer browser itself.

When your IE goes wrong, it may influence your browsing. Or, if the IE is revised maliciously, it is unable to surf smoothly. Therefore, you can reinstall your Internet Explorer.

Besides, you can also press “F8” to choose “Last known Good Configuration” and then press “Enter” to restore the Internet Explorer.

Not likely, at least not in anything you would care about. Technically speaking, it could add a few nanoseconds (not even 1ms) to processing and routing time. If you are seeing noticeable speed loss, there could be some other issue such as a virus on another computer, or simply just more computers connected to it.

That would only happen if you have an internet speed of well over 10mbps, and you have an older router that has only a 10mbps WAN port. Then, the router will limit your link to 10mbps....
