Problems with wireless router

Recently I purchased a D Link DI - 524 802.11g/2.4GHz Wireless Router for my home. This was purchased considering the option to be online from every corner of my house and be connected to my other laptop and desktop PC. The router was easy to install or maybe my experience working with SBC Global Yahoo made it simpler for me :p. Everything worked fine until my sister complained about she not being able to attach files on email using her laptop. As usual, I ignored her completely thinking that she is not so good when it comes to these devices.

One day later, I was trying to upload a few files over ftp and it wasn’t happening. I thought it must be the Internet connection and started writing a post on this blog. To my surprise I was getting a ‘page cannot be displayed’ error every time I tried to publish or save a post. I quickly wired my laptop to the router and it worked. I was pretty tensed now thinking that I would have to do this all time when I need to upload something or post on my blog.

I asked a few friends who use wireless routers. None of them were of any help. I did a lot of research on the Internet but that did not help me. I thought this router was a total waste of money and I should replace it when I found this person on wireless forums. This guy had replied to a worried person who had a similar issue like me. The resolution to this is very simple. Just go to your router by typing in the IP address in your browser (usually 192.168.1.1 or 192.168.0.1). Go to the WAN link and change the MTU value. I have it set to 1000 now and everything works like charm. I haven’t bothered about knowing what this exactly is but I will definitely find some more information and post it here. Hope this helps anyone who is facing issues with uploading or attaching files using a wireless router.
