Why can't I access MSN HotMail through my router?

I have a problem that neither Hotmail nor an otherwise helpful technician
can solve. I have within my home a network: Compaq desktop with a D-link
extreme G card, attached via a modem to an ADSL line, a separate router and a
new Tosh laptop with a wi-fi card. Everything works as it should, except that i
cannot access Hotmail from the laptop: any other URL can be accessed
immediately. I have had various “help” suggestions from Hotmail, including
re-installation of IE 6. Nothing works and my computer adviser has given up. If
I plug the ADSL line into the laptop direct, I can access Hotmail normally, yet
not when I do so remotely through the router and desktop. Do you have any
suggestions?

I have two guesses – one involves your router, and the other involves an
obscure network setting.

I’ve not tested this, but I wonder if HotMail is sensitive to what’s called
double NATing” and wonder if that’s
what you have happening.

Double NATing happens if you are behind two routers, each attempting to
perform “Network Address Translation”. I have seen several cases where a
broadband modem attempts to perform NAT, and thus in some ways it’s “acting
like” a router. If you put a NAT router in front of that modem, then you are,
effectively, behind two routers.

When you plug your laptop into the ADSL line directly, does your IP address
begin with 192. or perhaps 10.? If so, then it appears your ADSL modem is
performing NAT. Addresses that begin with 192 or 10 never appear on the
internet, but are assigned by routers when sharing a single internet connection
between several computers. If your modem is assigning you an address in that
range, then it’s pretty likely that it’s acting a little bit like a router. At
least in a way that we care about.

If that happens, you might consider turning DHCP off in your router and
seeing if a) all computers connected still connect to the internet properly,
and b) whether or not this resolves your problem.

My other guess has little to do with the router, but apparently has resolved
HotMail access issues for others. While I think of this as more of a long shot,
it’s possible that how you connect to the network could impact this.

There is an obscure network setting called “MTU” that deals with how packets
are sent on the network. Several people have reported that reducing the MTU
setting has restored access to some sites that they couldn’t access before.
This article: I can’t access
some websites … why?
covers the setting, and how to go about adjusting
it.

As I said, it’s a long shot, but it is something that could be affected by
your network topology.

  2. You can’t get to your free hotmail account from the laptop, you have to sign up and pay for the hotmail to get it on the laptop.

  3. Hi Leo,

    Love your site, it’s a godsend.

    I’ve been trying, with the previous posts, to figure out what may be wrong. I have been unable to access hotmail either since setting up a LAN.

    I run xp pro, and have a d-link wireless DI624M router hooked up to a d-link 302-g modem via ethernet cable.
    The main computer is in port 1 of the router, and a laptop runs off the wireless.
    Both function ok except for hotmail, gmail style addresses.
    I have changed the mtu on the main computer to 1492.
    I have looked into double nating. The NAT is disabled on the modem, so I presume that wouldn’t be a problem.
    Do you think port-forwarding may be the problem?
    Would I need to assign a static IP for the main computer?

    Any help you could give would be great. (ps, i’m not proficient in networking)

    Thanks, Ben.

  4. Leo you are the BOMB!!!
    This worked for me too, I have a comment to add. I couldn’t figure out the right number to put, I tried 1500 and 1492 but neither one worked. One of my other computers could access hotmail and myspace just fine, so what I did is run the little program on that PC and noticed that the number there was 1300, so I used the same number on the one that wasn’t working and all of the sudden Boom it worked. Once again thanks for taking the time to write this article.

  7. I have a D-Link DI-524 router. I never could get to hotmail through it. Finally, I wild ass guessed, and set the MTU setting in the router to 1200. It worked. I can get into hotmail, upload & download pictures, etc.

  8. Oh my god .. the MTU setting worked for me too !! I too have a D-Link DI-524 router which could not get to hotmail. I changed the default MTU setting of the router from 1500 to 1200 and now hotmail works !! I’ll try slowly increasing the MTU setting to see how far up I can take it.

    Thanks Leo & Tom Young !!

  9. I used my hotmail password yesterday prior to noon. When I needed to get bac k to read my email, it would not accept my password. I had not changed it. Consequently I signed up for the new version email [Email Address Removed] and now that wont accept my password. What gives? This is the second weekend that this happening.

  14. I had this problem ever since moving from Virgin to Orange broadband. I have a D-Link DI-524 router and all computers that had XP could not access hotmail, but the laptop that had vista for some reason. I called Orange who had no clue what they were doing after they had done their usually routine of checks. T
    At one point i was changing the windows clock to 5mins forward…?!?! Anyway, i came across this site and within 5mins problem was solved! I changed the MTU to 1200, restarted and could then access hotmail and the orange email. Btw i had to change the MTU on all of the computers that had XP.

  15. I had this problem whenever I was in my Ubuntu system, but not while in Windows. I couldn’t access yahoo mail, hotmail and moodle. Youtube always stopped working if I logged in.
    Adjusting the MTU setting solved all those problems, thank you very much.
