I can't access some websites ... why?

My wife can access all web pages from a wired connection, but when she goes wireless on the same computer, only some of those same pages can be accessed. For example, she can connect to the main page and some sub pages of U-Haul's web site but not to other pages (specifically http://store.uhaul.com/hitches.aspx). Would changing the MTU setting help with this situation? Thanks.

Possibly.

Two reasons I have had for not reaching some websites are:
1. The host file, when the link uses an intermediary advertising link like fastclick, which is in my hosts file. I remove the intermediary link from the address bar and go to the desired destination.
2. The javascript used is not completely proper and the browser I use does not handle it, but IE does handle it.

I wasn't able to get to some sites. I'm on XP home and have DSL. I have an dhcp assigned ip, but was using my dsl providers DNS entries for my network card. I got rid of the dns entries and the sites I couldn't get to showed up immediately. I'm guessing it was a temporary dns issue on their end. I thought adding a dns entry would speed things up. It worked since I setup my system three weeks ago, and all of a sudden just stopped. Go figure.

hey!! wow i love you man lol i cant belive it you fixed it!! ok well make sure you put down MTU numbers that he tells you to and not the ones that he has on his because i didnt listen lol and first i put 1500 and it didnt do anything but then i tried the 1492 and it worked .. oh and if you have windows xp you dont have to reboot you can just go into controll panell and then go to network connections, right click on ur connection and then click disable then enable it again by right clicking on ur connection and clicking enable

this made me able to get onto windows live messenger again and log onto myspace and onto hotmail so if you have those problems i strongly recommend this

ok I have what I consider a different scenario from the ones above. I cannot get to this website but I can ping it. I attempted it from my mother's pc which is a different setup browser etc and it had the same no response. But I could ping the website from my moms computer also. We are on DSL with a wireless network for my pc. so I decided to by pass the router and plug my moms computer directly into the DSL modem. Did that and still could not access the website. So it's not my router. SO i tried tweaking with the modem different things. I reset it completely. Disabled all firewalls. Still I can't get to this page in IE or Mozilla. BUT we have AOL for broadband that connects over our DSL connection. The bizarre thing is I can connect to the website through the AOL portal. Just not directly through Mozilla or IE. There is something that is simple that I am missing. Someone please point it out.

I would like this resolved so that I can get to it through my preferred browsers. I don't really use aol for broadband much and we are fixing to delete the account.

I appreciate any help you might could give.

I am kind of in the thinking that some how maybe my dsl carrier could be blocking the site but I have no idea how that would work or why.

Every time I try to log on myspace.com I will get a message saying internet explorer cannot display the webpage. I have tried everything I tried what you mention above and still cannot access myspace, this problem just occured a couple of days ago, please help.

Thanks much,

I read this thread...with so many solutions. I tried each one...but the answer for me was the one where they suggested that you change the dns setting in TCP from dynamic to a specific address of my router. That worked! I had fought this for HOURS... Thanks to all the contributors on this thread, i am now growing my hair back in.

Thank you very much! I would have never thought that the MTU was causing the issues I had on my home network.

I didn't use Dr. TCP. I went into the setup page of my Linksys router via my web browser (192.168.1.1) and found that I had the MTU setting disabled. Once I enabled it and set it to 1500 it fixed the problems I had with not being able to access certain websites. Thanks.
