Tip & How-To about Computers & Internet

CAN SEND BUT CANNOT RECEIVE EMAIL

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.

When I recieve an email, open it and clik on the picture usally it use to direct me to the web the email is coming from. Now when I do so, a window opens telling me 'This operation has been canceled due to restrictions in effect on this compt.Please contact your system administrator. What is wrong, or I am doing something wrong. Thank you


if this is a laptop check if this problem only occurs at certain places. For example if it is only at your home it may be an issue with a router, modem or even your ISP. See if you can bypass the router and connect your computer directly to the modem. Try to restart once connecting to be sure. If you are connecting without the router you may need to check the filters or open up ports. This would depend on the site those links are going to.
If the same issue occurs even at the office it may be a setting at your computer. Normally problems with links your email is diverted to the junk. At the top of these email it should prompt you to enable access to the link. See if you can enable them. You may do the same process for different links or programs but be careful. Only enable those you are familiar with.

i have this router for a week ,and no problems, but yesterday its fell,the router its working fine,but the laptop who receives internet from my router via wireless its show it conected to internet,but I can not connect to to a webpage.i installed the latest firmware but nothing happens,Sorry for my english but its not my first language


Make sure all the connections are secure. try plugging the laptop into the network cable directly and see if you can access a web page to verify that the laptop is working as it should. Try to connect a different device wirelessly to the router to see if the router is broadcasting as it should. Is the router broadcasting a SSID? Does the router have an antenna and is it attached correctly? Try to reset the router and connect.

Does your computer connect to the Internet okay at other wireless locations? Make sure you have the latest drivers in your laptop for the wireless network adapter. You should also verify that you have the latest Windows updates installed.

Is your computer sometimes used in a business network?? If so, make sure the "use proxy" setting has been disabled in your browser when using the dlink router.

Check the D-link website at http://www.dlink.com/products/support.asp?pid=565&sec=0#firmware to verify that you are using the latest version of firmware on your router. If it has any known problems, a firmware upgrade could fix it.

Let me know if you need more details on any of these points. Hope this helps!
