Websites Loading Very Slowly Or Not Completely

Websites Loading Very Slowly Or Not Completely



This is another common issue or problem i have seen around.Sometimes you may experience that websites dont load completely or they are very slow to load.There could be many reasons for this.But two common reasons for this is either slow DNS servers or wrong MTU settings.Most of our ISP's DNS servers are always overloaded as by default everybody uses the default DNS servers and since these servers get so many DNS requests, they do tend to slow down sometimes.Also Incase your MTU settings are incorrect you could experience websites not loading completely.Sometimes only half of the website would load or the whole website would load in textmode which would seem very weird.So here are the two ways you could solve your problem :

As i said there are two ways .Its always adviced to first try changing your DNS servers to opendns and then if that doesnt solve the problem go for the 2nd method which is changing MTU values

1)Changing DNS servers to OpenDNS - 208.67.222.222 and 208.67.220.220

How To Configure(Setup) Or Change Your DNS servers(Opendns) In Windows



This is a small tutorial to help you configure DNS servers in Windows.Typically ISP's DNS servers are very slow primarily because they are overloaded and cannot handle so many requests.opendns a DNS service has some really good DNS servers which are faster,more secure and definetly more reliable..The most important being FASTER.So this tutorial will help you change your DNS server from your ISP's DNS servers to OPENDNS servers.
Firstly, so that you know, opendns server ips are 208.67.222.222 and 208.67.220.220 .. typically two server ips are given,even from your isp.The first one is called Primary DNS server and the second is called Secondary DNS server.
OK, now on to the procedure..Its simple!!

2)Changing MTU values



How To Change MTU Values In Windows



Sometimes you may face problems connecting to the internet where certain websites may not load and others may..Like for example google.com might work but yahoo.com may not.Then the first thing which you would try to do is change your DNS servers ( mostly opendns :D thats what everybody tells you to do) .So you go ahead with their advice and change your DNS servers to opendns.Then reboot your pc and oops..what happened? Nothing???If nothing happened, then dont worry you can try one more thing, and that is changing your MTU values.
MTU meaning Maximum Transmision Unit is basically the size of the packet that is transmitted.Sometimes in certain cases default MTU values may not work depending on your network setup you might have an incompatible MTU configuration.So what you could do then is modify your MTU values.By default Windows uses 1500.Sometimes you may have to lower it down to say 1492 or 1454 to get things working!!
I would recommend you to first try 1492 , if that doesnt work you could try these other values like 1454,1460,1452 .

So here's how you do it in Windows

Step 1 : Go to Start-> Run ( or press the windows symbol on the keyboard + R) and then type regedit.exe in the popup window
Step 2 : You have now entered the registry,Navigate to HKEY_LOCAL_MACHINE\ SYSTEM\ CurrentControlSet\ Services\ Tcpip\ Parameters\ Interfaces
Step 3 : Now under the Interfaces key try finding the correct key which corresponds to your network adapter.. view the contents of the key by clicking on the key and see if you find a key with your network ip address somewhat of the form 192.168.1.x or 192.168.0.x .That would most likely be the correct key
Step 4 : Once you have found it Create a NEW DWORD VALUE by going to Edit -> New -> DWORD Value and call it MTU
Step 5 : Double click on MTU to open its settings and choose the Decimal Option and type the MTU value ( as i said, first try 1492 , if that doesnt work then try 1454,1460,1452)
Step 6 : Then click on OK and close the Registry Window and Reboot your PC
Step 7 : This should do the trick and hopefully will be able to browse all websites successfully!!
