Is It Possible For Someone To Access My Router And Block My Address How To Do That

I would like to block the mac address for these devices, but cant figure out how to do that.

The access control box is checked, but the only option I could see is whether to allow or to block all new devices from connecting.

If you still have problems, contact D-Link technical support for assistance at.

I have a PC running Windows XP Home Edition connected to a DSL line.

Until recently, it had never given me any problems.

My birthday had just passed and my uncle bought me a D-Link DI-624 wireless router.

As time went on, however, I noticed that my PC was having difficulty connecting to certain Web sites or sending and receiving e-mails.

These were sites and addresses that I have been using for some time now, so I couldnt understand the why I was having a problem.

So just to satisfy my increasing curiosity, I removed the D-Link router from my PC and plugged my DSL line directly into my PC.

To my surprise, all of the sites that gave me trouble were now working flawlessly.

I thought the router might be defective, so I had my uncle exchange it for me.

After installing the replacement, those sites became inaccessible again.

Do you have any idea what might be causing this problem, and how I can fix it.

Ive heard of this type of problem before, but never seen it first hand.

I wish you had included the links to some of those problem sites so that I could have tested this first before advising you.

The MTU is the largest size packet or frame, specified in octets (eight-bit bytes), that can be sent in a packet or frame-based network such as the Internet.

Too large an MTU size may mean retransmissions if the packet encounters a router that cant handle that large a packet.

Too small an MTU size means relatively more header overhead and more acknowledgements that have to be sent and handled.

Most computer operating systems provide a default MTU value thats suitable for most users.

If you frequently access Web sites that encounter routers with an MTU size of 576, you may want to change to that size.

Apparently some people have found that changing the MTU setting to 576 improves performance while others havent noticed any improvement at all.

In more recent Windows systems, the operating system can sense whether your connection should use 1,500 or 576, and it selects the appropriate MTU for the connection.

So I suggest you try decreasing your current MTU settings in increments of ten (e.g., 1,492, 1,482, 1,472 and so on).

To make this modification on your router simply follow these steps.

Click OK to enter the Web configuration page for the device.

Enter the new value in the MTU field and click the Apply button to save your settings.
