Tip & How-To about Computers & Internet
Verify if you are connected to the router you were able to receive an email.If even directly connected to the router you are not able to receive an email you may try to by pass the router and connect the computer to the modem and check if you can receive an email. If only through the router you are having problem with you may try the following steps to troubleshoot the problem:
a.Check your e-mail program settings the correct incoming server address, also known as the POP Server if you use a POP3 e-mail server. This address must be what your Internet Service Provider assigns for e-mail communication. If unsure of the setting, please contact your Internet Service Provider.
b.This is sometimes due to your ISPs MTU (Maximum Transmission Unit)being lower than what the router is set to. To adjust this correctly,follow the steps below:
To find the proper MTU Size, you’ll have to do a special ping of the destination you’re trying to go to. A destination could be another computer, or a URL.
1.Click on the Start button, select the Run option.
2.In the “Open” field type in command (If you’re using Windows2K/NT/XP use CMD instead).
3.Once the window opens, you’ll need to do a special ping. It should be formatted:
ping[url] [-f] [-l] [MTU value] [Enter] an example would be:
pingyahoo.com –f –l 1472
pingyahoo.com –f –l 1462
pingyahoo.com –f –l 1452
You should always start at 1472 and work your way down by 10 each time. Once you get a reply, go up by 2 until you get a fragmented packet. Take that value and add 28 to the value to account for the various TCP/IP headers. For example, let’s say that 1452 was the proper value, the actual MTU size would be 1480, which is the optimum for the network we’re working with.
4.Once you’ve found the optimum MTU size open up your browser,usually Internet Explorer, which is located on your desktop (Or on the Start menu in Windows XP).
5.Once Internet Explorer has opened inputhttp://192.168.1.1/Filters.htm into the “Address” bar.
6.You will be prompted for a User Name and Password. Leave the User Name blank and input admin as the password then click OK.
7.Under the Set up tab set the MTU to manual and input the optimum value you got earlier. So for our example this would be 1400. Hit the Save settings button then you are done.
Hope this help everyone.
